Ventilation requirements for Scottish based Dental Practices
Ventilation systems have always been an important part of an enclosed space, regardless of its use. However with the Covid-19 pandemic, ventilation and the circulation of air in enclosed spaces has gone under the microscope. In June of 2021, the Scottish Government released details of a new policy on ventilation requirements in dental premises in the country.
What are the ventilation requirements?
Ventilation system used in dental practices will now have to meet the set requirements of 10 air changes per hour.
The transmission characteristics of viruses and the level of risk in a surgery following an aerosol-generating procedure (AGP) means that ventilation requirements in dental practices have had to be amended. It is estimated that currently, on average, most dental surgeries in Scotland achieve six air change per hour (ACH). This means that it can take up to 60 minutes to clear infectious particles from the air in an enclosed dental practice room. With the new legislation requesting a dental surgery achieve a minimum of 10 ACH, this will make the area safe within just 20 minutes.
Why is ventilation in a dental surgery so important?
The airborne transmission of viruses such as Covid-19 can make dental practices a dangerous working environment for both dentists and patients. It is important to protect both key workers and patients and reduce the amount of ‘spatter’ that can be emitted into the air during dental procedures. To do this, sufficient ventilation systems must be in place to aid the removal of these airborne diseases.
The Air Changes per Hour (ACH) is the measurement that tracks how many times the air is changed per hour in a given space. In a working environment such as a dental practice, it is important to make this space free from any viral or bacterial pathogens in as short a time as possible. Put simply, the more air changes per hour, the less risk to both dental teams and patients.
How can a dental practice make changes to the ACH?
There are three ways that a dental surgery can affect the ACH:
Reduce
Reducing the number of pollutants, microbes and air borne viruses from being introduced to the air.
Dilute
Having an effective ventilation system installed that allows enough clean, fresh air to enter a space and dilute the pollutants in the air.
Purify
Air purifying systems that can remove a number of pollutants from the air.
Effective ventilation is the primary focus for the new Government guidance and they are advising that external extractor fans are now required to keep spaces well ventilated and that the ventilation system is powerful enough to ensure a maximum fresh air flow rate. The Aerosol Generating Procedures (AGP) is dependent on the ventilation and rate of air change within a room.
The new Scottish Government guidelines state:
For a treatment room with more than 10 air changes per hour (ACH) and which can be evidenced to the NHS Board, a minimum of 20 minutes ‘fallow time’ (after which entrance to the room without PPE is allowed) before cleaning is recommended.
For a treatment room with external ventilation (natural or mechanical) with less than 10 ACH or with no data on number of air changes per hour available, the fallow time would be 60 minutes.
For a treatment room with no external ventilation (natural or mechanical), the absence of air changes means that AGPs should not be undertaken.
What is the Fallow Time?
Fallow time is the term that refers to the settlement period. In dentistry, the number of procedures available means that a lot of airborne ‘spatter’ is produced. To reduce the number of infectious micro-organisms in a dental setting, the fallow time requires a set period of time to pass before the next dental patient is allowed inside the room for treatment. Ventilation systems can reduce the fallow time between patient appointments and reduce the infection rates, keeping dental teams and patients safe.

When it comes to celebrating business anniversaries, many come and go in the blink of an eye.
But whatever the anniversary may be, they act as a vital marker that allow us to step back and recognise the accomplishments we have achieved in the past whilst laying the foundations for our growth into the future.
And that is why we are incredibly proud today to be celebrating 25 years since our team in HF Comms first began their journey.
With so many milestones along the way, we are incredibly proud of the work we have done to help our clients shape the ground breaking communications sector across the UK. Whilst we can’t list them all, some of our landmark achievements over the last 25 years include:
– Creating the infrastructure for allowing passengers on planes to access Wi-Fi in the UK
– Creating Air to Ground Installations for the Emergency Services Network
– Upgrading communication systems across Scotland to 5G capability
– Creating the infrastructure in Scotland and London to serve the UK’s Smart Meter rollout
Few industries are as fast moving as the communications sector and even fewer are as competitive. Which makes reaching our 25th anniversary all the more significant. We have faced and overcome so many business challenges from fuel shortages and 2001’s foot and mouth outbreak to recessions and pandemics. It is a testament to our teams truly outstanding approach that we have continued to grow through all of it.
But as with everything in Comms, it is not about looking back, it is about looking forward to the next 25 years and beyond.

The National Security Inspectorate (NSI) is one of the UKs most highly trusted and respected accreditation for Fire & Security providers like ourselves.
They are a completely independent organisation that is a not for profit organisation that helps to protect residential home owners and businesses across the UK.
As an NSI approved company, we are committed to the highest standard for our Fire & Security services, quality and continued desire to improve our services for our customers and are delighted to be part of the NSI as they celebrate 50 years.
Starting in 1971 as the National Supervisory Council for Intruder Alarms (NSCIA), the NSCIA became the NACOSS in 1991 thanks to a merger between the NSCIA and the SSI (Security Systems Inspectorate) and their quality assurance scheme was launched.
In 1992 the Inspectorate of the Security Industry (ISI) was formed and NACOSS received the NACCB accreditation to deliver BS 5750 Quality Assurance Certification which was the precursor to ISO 9001.
In 1999, NSI became a founding stakeholder in the apprentice Engineers of Tomorrow and then in 2002 became the first certification body licensed by BAFE to provide third party certification for providers of fire detection and alarm systems.
In 2012, NSI was granted UKAS accreditation that allowed them to deliver BAFE’sLife Safety Fire Risk Assessment Scheme SP205.
By 2016, the number of NSI approved companies in the UK had reached 1800 and as the company is now celebrating 50 years of delivering certification and raising the standards for Fire and Security across the UK, we look forward to the next 50 years.
Security Fogging – If you can’t see it, you can’t steal it
In the world of fire and security, there are alarm systems, CCTV cameras, door access systems, locks and gates that can be installed to help deter and prevent robberies.
There is however another security option that you may not know about and that is security fogging.
The principle is simple. If a thief can’t see, they can’t steal. Which makes this the ideal security prevention system for many business sectors that need a security method that can help reduce ‘smash and grab’ robberies.
How does security fogging work?
Security fogging is a fast acting high density fog that is released by a sensor. It can deliver 28 cubic metres of fog per second at 30cm density with a reaction time of just 0.1 seconds before full speed fog ejection.
Security Fogging leaves no residue and is certified to comply with EN-50131-8 Standard.
Where is security fogging used?
From high end luxury brand stores to local convenience stores, security fogging can be widely used to protect employees and valuable store assets against the threat of robbery. An installed Security Fogging system can protect an entire room in just a few seconds (one security fogging unit can sufficiently cover an area between 40m³ to 500m³) leaving thieves little opportunity to grab any valuables.
The fast acting system means that intruders are quickly stopped in their tracks as visibility is reduced to zero and they simply can’t see anything that is further than 30cm away.
Popular locations for Security Fogging include:
Retail Stores
Jewellers/Pawnbrokers
Petrol Station Forecourts
Electrical Stores
Museums/Art Houses
Domestic Properties
Is the security fogging gas harmful?
The fog system is completely harmless to people and safe to use in any store as it leaves no residue. So whether you are wanting to protect clothing, jewellery or consumer electrical equipment such as TV’s, security fogging is an ideal solution.

You have seen them in Sci Fi movies and you have heard that they are coming to a high street near you soon but how do driverless cars work and are they the future of transportation?
New cars coming onto the market are now able to offer some level of self driving mode. The most limited of which is parking assistance technology that will literally park the car for you. But the future of self driving cars is far more reaching than simply a parking tool.
A fully functioning self driving car (when they are commercially available and legally allowed to be used on UK roads) uses a large number of sensors, cameras and radar scans to identify and monitor the vehicles surrounding area. This allows it to monitor the road for hazards such as other vehicles, pedestrians, traffic lights and safety road markings. Using this information, the vehicle can then accelerate, rake and steer.
But monitoring the road is only one part of how a self driving car works. Its on board computer can follow both pre programmed algorithms and commands but can also learn and make its own decisions based on the vehicles unique experiences. While this may seem like something out of an AI movie, it is an essential part of the vehicles ability to adapt to changing traffic conditions or if it is travelling along unmapped roads.
Examples of self driving car features already available in the UK
While self driving cars are not currently available in the UK, some of the features of a fully functioning self driving car are already available in cars on the market including:
Adaptive Cruise Control
There was a time when cruise control was simply activating a set speed for the car which then kept at said speed regardless of what was happening on the road. Adaptive cruise control uses radar to maintain a set distance from the car in front. This same system will be a vital component in future driverless cars.
Parking Systems
Many higher spec luxury cars now come with a driverless technology that uses cameras and sensors to park the vehicle for you. It can judge if a parking space is big enough then can take over control of the steering, speed and braking of the car to carry out the parking process for you.
Lane Assist
Lane assist tracks the painted lines of a road and helps to steer you back into the lane if you begin to drift off line.
Emergency Braking
A vital component of self driving cars will be their ability to stop. And that feature is already well in use on vehicles on the road. Using radar to scan the road ahead, a cars computer can activate the breaks of your car if it detects an imminent collision. The reaction times of the computer can dramatically cut your speed and stopping distance to either stop an accident or reduce its violent impact. The latest radar systems on high end cars can also recognise pedestrians as well as other vehicles.
Where HF Comms comes in
For driverless cars to truly become a part of our day to day lives, widespread 5G availability will be essential. And that is where HF Comms comes in. We are one of the leading telecommunications companies in the UK and as part of ongoing contracts with existing clients, we are currently helping to upgrade the UKs 5G network.
Car manufacturers will not begin pushing the full development of driverless cars until the infrastructure (including a full 5G network) are in place. Manufacturers such as Tesla only currently offer semi autonomous driving capabilities using the onboard sensors and cameras with network communication only utilised as a secondary means of communication.
Whether is is driverless cars or communication tower builds, there are few areas of industry as fast-moving as the Communications sector.
Certainly, there are few as competitive. In this climate, HF Comms has grown and developed almost as quickly as the sector itself. If you would like to know more about HF Comms and our range of telecommunication services, please contact us today.
5G is simply the name for the 5th generation of mobile network technology.
Like 1G, 2G, 3G and 4G before it, 5G is the latest step in communication network that allows more people to be connected and more technology to work seamlessly with each other in the background.
Designed to deliver a higher multi-Gbps peak data speed along with ultra low latency and an improved reliability in connection and signal strength all backed up with increased availability.
5G is based on Orthogonal Frequency Division Multiplexing also known as OFDM which is a method of modulating a digital signal through multiple different channels that helps to reduce interference.
Based on the same networking ideas behind 4G LTE, 5G can operate in both lower bands sub 6 GHz and mmWave from 24GHz and beyond.
5G technology will deliver a faster, stronger mobile broadband service that will see vast improvements over the current communication networks we use on a day to day basis for both personal devices and business needs.

Wifi is everywhere. From Coffee shops to Office Buildings. Your home and even now on an airplane.
Wireless networks (aka WiFi) is a wireless network of radio waves (just like you have for your mobile phone) that connects your computer/smart phone/devices to a wireless router which takes the signal received, decodes it and then sends that information onto the world wide web using a physical ethernet wired connection.
The system works both way so you can send and receive wireless information using WiFi. Similar to how a walkie-talkie works, WiFi signal is transferred in radio waves and then converted into 1s and 0s. WiFi signal is generally transmitted at a frequency of 2.4GHz of 5 GHz (you may even have a WiFi box at home that produces both signals though these are being phased out as they carry lower data speeds). This signal frequency is a lot higher that what you find on a mobile phone and the higher the frequency, the larger amount of data needs to be carried.
HF Comms
There are few areas of industry as fast-moving as the Communications sector.

When a fire breaks out in a business premises and the fire alarms are activated, your first thoughts will naturally be to leaving the dangerous area quickly and safely.
However if the fire has caused a power cut and the room is filling up with smoke, finding your way out may be a bit more tricky than you would have thought – regardless of how well you know the lay of the land.
And this is why emergency lighting systems are so important for the safety of your workforce, customers and on site visitors. We all pray that we never have to go through the dangers of a building fire but it can happen and this is when an emergency lighting system can become a truly priceless safety feature for your business.
Around a third of fire related deaths in the UK are because of gas, smoke and toxic fumes. So getting away from them as quickly as possible is so vital. So what does emergency lighting do?
Emergency lighting is as the name suggests, lighting to be used in the event of an emergency. There are different types of emergency lighting available that businesses can choose from.
Illuminated emergency exit lights glow green and are used to highlight emergency exit doors or point towards the nearest exit.
Bulkhead emergency lighting is a system of lights fitted in the ceiling that provides light to the emergency route. This system ensures that there is enough light so that people evacuating the building in the event of a fire can see where they are going. Studies have also shown that this can help to reduce the level of panic as people leave the building and cuts down the chances of other accidents as people rush to leave. Bulkhead lighting systems need to be placed along the centre line of an escape route. This is not about aesthetics, this is about ensuring that in the event of a fire, people can clearly and easily see where they are going as they head to an emergency exit.
In the UK, the Regulatory Reform Order of 2005 states that:
“Emergency routes and exits must be indicated by signs; and emergency routes and exits requiring illumination must be provided with emergency lighting of adequate intensity in the case of failure of their normal lighting.”
Installation is one thing – maintenance is another
Emergency lighting needs to be checked on a regular basis to ensure that it is in good working order. Annual emergency lighting tests need to be carried out by trained Fire Alarm Servicing Companies like ourselves.
Emergency lighting test results need to be recorded and any faults in the system need to be noted and resolved as soon as possible.
Emergency exits need to be clear of any obstructions and passageways needs to be clear of objects that can slow people down or are deemed trip hazards during a building evacuation.

With reduced energy bills and lower maintenance costs, it is easy to understand why warehouses and storage facilities are so keen to make the switch to LED lighting solutions.
Brighter, more energy efficient and with a longer lifespan; LED lighting is helping warehouses become a safer environment with well lit indoor areas that no longer suffer from the frequent flickering of fluorescent lighting fixtures which also give off a disconcerting buzzing noise.
Why LED Lighting is so effective in Warehouse Environments
What makes LED such a popular choice is that there is not just one or two benefits to switching to this energy saving form of lighting, there are a number of real benefits including:
Increased colour rendering
In a warehouse environment where natural light is so limited, having lighting that helps to properly illuminate a working environment is vitally important. LED lighting has a strong Colour Rendering Index (CRI). This is is a measurement of lights ability to reveal the colours of objects in comparison to an ideal light source – aka natural light from the sun. LED light bulbs have a high CRI. This means that in darker environments with low levels of natural light, LED lighting can illuminate more objects in a surrounding area thanks to a higher CRI.
Reduced heat output
Older lighting solutions such as halogen bulbs give off more heat energy than they do light energy. LED lights are able to operate at a significantly lower temperature compared to fluorescent or halogen lighting fixtures and what little heat they do give off is actually dissipated in a special heat sink within the light fixture. And because LEDs do not emit infrared radiation, they are ideal for lighting heat sensitive areas traditionally found in warehouses and storage facilities.
Increased Brightness and Intensity
LED lighting is capable of emitting a far higher level of light power compared to halogen or fluorescent lightning fixtures while requiring a lot less energy to do it. This means that not only do you cut your warehouse energy bills but you actually need less LED lighting fixtures (depending on what type of LED light fighting you select) to light the room to the same intensity as before.
Long Life
A warehouse traditionally has higher ceilings with lighting fixture locations that are difficult to access without ladder systems. The components of an LED light and the way that they generate light means that they have a far greater lifespan than other light sources. A traditional light bulbs filament will weaken over time which causes the bulb to burn out – LEDs do not burn out. An LED’s bulb produces low heat levels, is durable and energy efficient which makes it possible to outlast other light bulb types by thousands of hours. This means that maintenance requirements for LED lighting is far less and can be easily scheduled into other maintenance plans in a warehouse setting.
Find out more
These are just some of the advantages of switching to LED lighting. There are far more benefits to LED lighting covering everything from design flexibility to day to day reliability. But whatever way you look at it, LED lighting offers considerable benefits to warehouse facilities (and other large scale internal lighting locations) that are looking to cut down on their energy bills and maintenance requirements whilst offering a well lit, safe working environment.

The Loch Lomond to Lorimers Walk Charity event is coming up
Now that we are into September, the Loch Lomond Shores to Lorimers Charity Walk is fast approaching.
This incredibly worthwhile charity fund raiser will be held on the 25th of September and is the ideal way for ramblers, hill walking enthusiasts and those whole love raising money for a good cause to take part in a scenic walk that starts at Loch Lomond shores. The walk takes us along the River Leven and following the popular cycle track to the Erskine Bridge before completing the final two miles to Lorimers Bar in Bishopton. And of course a collection of the HF Team will be participating as we help to raise more money for this great cause. For nearly 60 years, the British Heart Foundation have been pushing to reduce the number of lives lost to heart and circulatory diseases in the UK.
To find out more about the event itself use the link below.
The annual Texas Scramble Fundraiser event once again took place at the end of August at the Erskine Golf Club.
Held in memory of Jenna to raise the vital funds needed for the British Heart Foundation, HF Group were once again the proud sponsor of ‘the hole in one prize’ having been an active supporter of the event for many years.
And after another fantastic day out raising money for such an important cause, we are delighted to report that the event will have raised over £8,000 which will go towards helping the British heart Foundation continue their important work.

Why interconnected smoke alarms are a better solution
Smoke alarms have been saving lives in the UK for decades; and study after study has shown that a smoke alarm can cut in half the risk of dying in a house fire.
Yet there is always room for improvement. Which is why the introduction of interlinked smoke alarms and fire alarms is helping to make this early warning system a far more efficient and effective life saving device.
For all the lives that smoke alarms have saved over the years, standalone smoke alarms are actually quite limited in their function because, while they can detect smoke and sound an audible alarm, there is a limit to how far this warning sound can travel in a building. If, for example, a fire broke out in your living room at night while you are sleeping upstairs, the sound of the smoke alarm (when triggered) has to travel through a closed living room door, up the stairs and through a closed bedroom door whilst still having enough audible sound that it can wake you from your sleep. For those who are deep sleepers, this may not be enough to wake you in the event of a fire.
An interlinked fire alarm however can trigger all the alarms in the home when smoke is detected. Regardless of where the fire originated or which interlinked alarm was first activated. This means that wherever in the home you are, the nearest smoke alarm (because they are interconnected) will trigger and activate in the event of smoke in the house.
Heat, smoke and carbon monoxide detectors
What makes this new technology even more impressive is that heat alarms, smoke alarms and carbon monoxide alarms can all be interconnected in the same network so that if your homes gas boiler is leaking carbon monoxide, the alarm can trigger the entire network of devices and not just the carbon monoxide alarm located next to the gas boiler. Carbon monoxide has no smell or taste and can kill if you are exposed to high levels of it. Having an interconnected alarm system fitted can save your life.
It is becoming legislation that homes in Scotland must have them fitted
The new standards require the following:
Minimum of one smoke alarm installed in the most commonly used daytime room of the home.
Minimum of one smoke alarm installed in every circulation room ie. the hallway or landing.
Minimum of one heat alarm installed in the kitchen.
Homeowners who do not have interlinked fire and smoke alarms fitted after this date and who then suffer from a fire in their home may see their insurance cover rejected. This is an incredibly important new piece of legislation in Scotland.
At HF Fire & Security, we can provide a complete smoke alarm installation service and update your existing fire and smoke alarm systems to meet the new Scottish Government standards.

It is estimated that by 2030, there will be around 30 million electric cars across the roads of Europe.
With so many battery powered cars hitting the roads, one of the big concerns about electric vehicles, alongside range anxiety, is what happens to the batteries after the car has reached the end of its life?
Modern electric vehicle batteries are capable of 100,000s of miles worth of use, far more than the life expectancy of the vehicle in question. This means that even after 200,000 miles worth of use, an electric car battery is still theoretically operating at between 85 and 90% (depending of course of climate and what kind of usage it has had). If the battery is then replaced, it can still fulfil a use repurposed for other tasks rather than being recycled.
Various car manufacturers are now offering recycling solutions for the lithium ion batteries found in electric vehicles. Nissan, for example, is reusing the electric batteries in its own factories while Volkswagen have created a battery recycling centre that can process thousands of batteries every year.
When it does come time for the battery to be retired, what happens next?
Recycling capabilities for electric vehicle batteries are developing faster and faster. They are now at the point where they can grind down the components of an old electric car battery and extract the raw materials including lithium, nickel and manganese to then be used to make new batteries.
As with so many developing technologies in the green energy sector, things are moving incredibly quickly and with every day, we are making new and exciting advances that can help us get to Net Zero faster.

In the food and drink industry, a walk in cold room or freezer room can have many benefits to increase efficiency and safety within your business.
With easy access and good storage capacity, a walk in freezer is ideal for large turnover businesses that deal in regular stock rotation of consumable products that require cold storage conditions. But what are the real benefits of walk in freezers?
Even Temperature Control
Whether you are storing meat, fish, dairy or other food, even temperature control is vital to keep the products being stored at the right temperature. By preventing the cold air from escaping the storage area you can keep the temperature stable and keep the products in storage safe.
Freezer Burn
The temperature range of walk in freezers can prevent freezer burn and can slow down the deterioration of products (compared to other freezer set ups). This means that you can store products for longer and minimise waste.
Improved Access
As walk in freezers are used everyday, easy access is important. Walk in freezer and cool rooms not only have the benefit of increased storage but with easier access, helps to enhance productivity and operational efficiency because products can be more easily accessed.
Increased Capacity
Saving the best for last, walk in freezers offer businesses increased capacity. In a walk in chiller where you can store a wide variety of products, it means your businesses can use extra storage space for long-life products and is a very handy feature to have come popular periods of the year such as Christmas when extra storage for food becomes so vital.

Keeping up with technology has always created sales opportunities in the tourism and hospitality sector.
And with the wave of car owners now switching from combustion engines to electric vehicles, there is real opportunity for Hotels to gain a service advantage over their competitors by having EV Charging Points installed in their Hotel Car Parks.
Electric Vehicles are not just a trend. They are the future of personal transportation. From Audi to Jaguar, Ford to Mercedes. All of the most well known car manufacturers around the world are committing to ending the production of combustion engines within the next decade or so and switching 100% to electric.
This means that frequent guests of a hotel including family holidays, business trips and other travelling sectors will be looking for nightly accommodation that has the ability to recharge their vehicles.
Hotels across the UK are already taking advantage of increased sales turnover because they have become early adopters of EV Charging Points in their premises. And why not. They are the perfect type of business to have EV Charging Systems installed and it offers them a significant sales opportunity over nearby hotels that do not offer charging facilities.
Reasons why a hotel is perfect for electric vehicle charging
From check in to check out, a hotel guest can leave their car in the parking spot all evening, night and morning. A perfect amount of time to charge their vehicle. For guests who are not staying at the hotel overnight and instead are there for other hotel functions such as a wedding, business function, trade show etc, this still offers ample time for EV charging systems to suitably charge an Electric Vehicle.
Hotels also benefit from EV charging points because their car parks are already ideally laid out to accommodate a large number of parking spots for guests. Off street parking of course is essential for EV charging points.
Who can use EV Charging Points at a hotel
Guests, Hotel staff and even Hotel Transportation Vehicles can all benefit from EV Charging onsite. When a potential hotel guest scans through the filtering options when looking for a hotel, there are some criteria that are more important than others. Wifi, breakfast facilities, a swimming pool…..and now EV Charging Facilities. Having a place to charge your electric vehicle while you relax on a night away gives guests a new level of peace of mind. For the hotel themselves, they can take advantage of running an electric vehicle and benefit from the onsite charging services.
Offering a sales feature to more than just hotels
Hotels are of course the easiest example of a hospitality service that can benefit from Electric Vehicle Charging. But Guesthouses, Holiday Lets, Lodge/Cabin Hire and Bed & Breakfast locations can all benefit from having an EV Charging Point fitted. As more and more motorists make the switch to electric vehicles, the demand for charging points will naturally increase with it. Getting an early start over the competition is a smart business decision.

No single fire extinguisher is suitable for all types of fire.
For this reason, it is vital to understand what is the most likely ‘type’ of fire that you may have on your business premises because choosing the wrong type of fire extinguisher can actually be more dangerous than the fire itself.
Understanding the different types of fire
In the UK, fires are classed into group types with each fire class being assigned a letter and visual identification symbol to help users select the right type of extinguisher (the exception to this is Electrical Fires).
Class A Type Fires
Fires burning through solid fuel such as wood, plastic, paper and soft furnishings.
Class B Type Fires
Fire created from flammable liquids including petrol/oil and paraffin.
Class C Type Fires
Gas based fires such as propane, butane and methane.
Class D Type Fires
High heat fires involving burning metals such as magnesium.
Class F Type Fires
Traditionally kitchen fires involving cooking oils and fats.
Electrical Type Fires
Electrical Fires are assigned their own class because in the event of an electrical fire, it is not the electricity that is burning but the components and surrounding materials that are burning having been set alight by the electricity.
Understanding the different types of Fire Extinguisher
There are multiple types of fire extinguisher available on the market. Each one has a specific fire class that they can be used on. In the UK, Fire Extinguishers are red to represent that they comply with current British Standards BS EN3.
Water based Fire Extinguishers
Water fire extinguishers should only be used on Class A Type Fires. They should not be used on electrical fires or fires involving flammable liquids.
Foam based Fire Extinguishers
Can be used on both Class A and Class B Type Fires. Foam based Fire Extinguishers help to prevent fires from ignition.
CO2 based Fire Extinguishers
Used for Electrical Fires and Class B Type Fires created from flammable liquids including petrol/oil and paraffin.
Dry Powder based Fire Extinguishers
While not recommended for use indoors, Dry Powder Fire Extinguishers can be used on Class A, Class B, Class C and Electrical Type Fires.
Specialist Powder based Fire Extinguishers
Specialist fire extinguishers that are designed for metal fires and are ineffective for all other class types of fire. Generally found in manufacturing facilities.
Wet Chemical based Fire Extinguishers
Commonly found in restaurants, kitchens and food production facilities that have cooking oils and fats.

LED lighting is a popular choice for businesses across the UK to switch to.
There are many advantages for commercial, retail and industrial business sectors when upgrading to LED lighting from inefficient halogen and compact fluorescent lamps (CFL).
To help explain the benefits of upgrading to LED lighting, we have listed 8 of the top advantages for your business of switching to LED.
1 – Energy Efficiency
Energy efficiency in lighting solutions are looked at in two ways. Luminous efficacy and useful lumens. This describes the amount of light emitted per unit of power (watts) by the light source. Upgrading to LED lighting can result in 65% or more improvement in energy efficiency of your business facilities lighting. If you are currently using outdated and energy inefficient lighting, this energy saving can be even more.
2 – Long Life
The components of an LED light and the way that they generate light means that they have a far greater lifespan than other light sources. A traditional light bulbs filament will weaken over time which causes the bulb to burn out – LEDs don’t burn out. An LED’s bulb produces low heat levels, is durable and energy efficient which makes it possible to outlast other light bulb types by thousands of hours.
3 – Increased Brightness and Intensity
Because LED lighting is capable of emitting such a high level of brightness, it can offer increase lighting power over halogen meaning that not only does it require less power to turn on an LED light. You actually need less LED lights to achieve the same room lighting. Which can save you even more in running costs.
4 – Reduced heat output
It is well known that older lighting solutions gave off more heat than light energy. LED lights are able to operate at a significantly lower temperature and what little heat they do give off is actually dissipated in a special heat sink. And because LEDs do not emit infrared radiation, they are ideal for lighting heat sensitive areas such is in food production facilities, Museums and medical facilities.
5 – Reliability
LED lighting is a far more reliable lighting option. Not just because of the increased lighting hours that they provide. But because they can operate in colder temperatures (ideal for walk in freezers) and are more durable to impact and vibrations because they have no filament or fragile parts they are a more reliable option for busy commercial and industrial facilities that need reliable lighting solutions through all hours of the day.
6 – Increased colour rendering
LED lighting has a strong Colour Rendering Index (CRI) which is a measurement of lights ability to reveal the colours of objects compared to an ideal light source aka natural light from the sun. LED lighting with a high CRI makes them an ideal solution for night time security lighting where they can illuminate more objects in a surrounding area thanks to a higher CRI.
7 – Design Flexibility
LED lighting can be bunched into a unit to replace larger bulbs or be arranged in isolation in smaller devices. They can be strung out in a sequence and come in a wide range of colours. In fact, LEDs are available in a wide range of Correlated Colour Temperature (CCT) values ranging from Cool to warm, yellow, white light and so much more. This design freedom means that they can be used to great effect by interior designers, retail stores, museums and so much more.
8 – Instant results
While CFLs take a few moments to warm up and an incandescent bulb works by heating a filament to a temperature that produces light, LEDs are instantaneous and operate at full brightness the moment you flip the switch.

While you may assume that electric vehicle charging is only reserved for those with off street parking, there are options available for those who have to leave their vehicle on the street overnight.
Being able to charge an electric vehicle is not just reserved for those with garages, driveways and other off street parking options because while the majority of homeowners in the UK (60/40) have some form of off street parking that will allow them to recharge their electric vehicle, the infrastructure that is being put into place is creating a whole range of options for those wanting to make the switch to electric vehicles but are worried about charging options.
Supermarkets and Retail stores
More and more supermarkets and other retail stores are having EV charging points added to their car parks as a sales tool to increase foot traffic. For supermarkets, it is a great way of keeping customers shopping for longer or taking advantage of the in house cafe/restaurant facilities that so many of them now have. For retail outlets such as a furniture store, it is a great way to attract customers to their show rooms for a browse in person.
Gyms/Leisure Centres
If you are a member of a gym that has electric vehicle charging facilities then you can recharge your vehicles battery while you enjoy a swim or workout.
Workplace Charging
Office buildings on the outskirts of Towns are now installing more ev charging points as their employees switch to Electric vehicles. You can now charge your vehicle the whole time you are at work.
On Street Charging
There are new on street charging options becoming more readily available and while they may not be available in your location right now, it is only a matter of time as with more and more drivers switching to EV, the demand for these charging systems is only increasing.
Running an extension cable
Your plugs at home are deemed as ‘slow chargers’. It can take around 30 hours to fully charge a modern electric car from empty to full using a 3-pin plug. Most car manufacturers recommend a three-pin socket method of charging as the last resort but if you are desperately struggling to charge your electric vehicle using any other method, this is still a viable, sporadic option.
With more advances, the need to charge all the time is reducing
While there will always be those with ‘range anxiety’, modern electric vehicles can cover hundreds of miles between charges. That means that there is less need to charge your electric vehicle. And that means that there is less need/worry about having to have off street parking to facilitate your recharging.
If you drive (for example), 50 miles a week going back and forth between work then you can very easily replenish this electric energy during a weekly supermarket shop or trip to the gym.
Did you know?
There are currently incentive grants available for both domestic and commercial use that can lower the up front costs of installing an EV Charge Point?
Find out if you are eligible. All you have to do is answer a couple of simple questions.
The difference between commercial plumbing and domestic plumbing
The difference in commercial plumbing and domestic plumbing can best be looked at in both scale and usage.
Commercial plumbing deals in the water supply and drainage systems for businesses, public spaces, leisure centres, industrial and manufacturing facilities etc that have extensive plumbing systems that are more demanding by nature that residential and domestic plumbing. The scale to which commercial plumbing has to operate in is almost unlimited; covering everything from public bathrooms to water heating systems for swimming pools and water systems for manufacturing facilities. Bigger buildings, bigger equipment and of course, bigger plumbing problems when they do arise.
Maintaining, repairing and installing larger and more complex plumbing systems for clients, operating to set design blueprints that often require customised fitting requirements.
Residential plumbers will normally operate in buildings that cover two to three floors where gravity plays a major part in the smooth running of water pipes and the pressure required to deliver water to the various supply points in a building. Commercial plumbers such as ourselves have the skills and experience to design, install and maintain the plumbing and pipework systems of complex building structures that run over multiple levels. We work with plumbing systems including industrial grade heating systems, piping and water supply needs.
While the requirements for residential and domestic plumbing are themselves complex, there is less demand on the plumbing system of a family home that covers two floors and two bathrooms compared to a multi story hotel that covers (for example) 10 floors, with one hundred rooms, each with a bath, sink and toilet to operate reliably every hour of every day of the year.
At HF Group, our Mechanical Commercial Plumbing and Heating Division is responsible for installing and maintaining piping and drainage systems, fire sprinkler systems, heating systems, ventilation systems, water drinking services, bathrooms, kitchens and so much more.
And because of the nature of commercial plumbing, we can operate outside of the traditional 9-5 operating hours to ensure that your businesses daily operations are not disturbed.
The name HF occupies an unprecedented position in industry across the UK. We have diversified and developed abreast of industry advancements and have grown into a group of world-class companies leading the way in next-generation technologies; and all with a family continuity at management level which is rarely seen. Faced with today’s business challenges – recessions, pandemics, takeovers and mergers, this is testament to HF’s truly outstanding approach.

There are hundreds of ways that a fire can start in a home and with the number of electrical devices now included in our daily lives, it is little surprise that electrical fires are becoming a more serious threat.
But while you may think that the majority of electrical fires comes from bad fittings and faulty installations, nine out of every ten electrical fires is actually the result of electrical products.
Here are the five products that are the most likely to cause electrical fires.
Electric Cookers
Electric ovens and microwaves are one of the top causes for electrical fires in the home. This does not include deep fat flyers.
Washing Machines / Tumble Dryers
Washing machines and tumble dryers are a common cause for electrical fires. While there have been well documented cases of manufacturing faults that cause fires, the electrical wiring of the devices are the main cause of fires in the home.
Electrical Lighting
Light bulbs can become very hot (except LED lighting) and whether they have become too close to fabric light shades, have been knocked over or one of many other reasons, electrical lighting can be a dangerous cause of fire in the home.
Portable Heaters
In the depths of winter, many homeowners turn to portable heaters for an extra boost of warmth. But dust build up can easily create a fire inside a portable heater. Despite manufacturer warnings, many people still hang wet clothing over their portable heaters which can then catch fire. And of course there is the risk of electrical faults within the heater that can cause a fire.
TVs
TVs cause more fires in the home than irons that have been left on. The risk of a TV catching fire increases if you leave an older model of TV on standby for long periods of time and despite manufacturer warnings, many home owners will hand their flat screen TVs above a fire place. The added heat escaping from the fireplace can cause the TV (which itself can generate a lot of heat) to overheat and catch fire.
What can be done
While some of the causes of electrical fires can come down to sensibility of the home owner (ie. don’t hang clothes over a portable heater), regular electrical inspections and PAT testing can be an invaluable safety measure to reduce the chances of electrical fires in the home. And while there are many things that can be done to prevent a fire, you should always make sure that you have a working smoke alarm system to help get you and your loved ones out of the home.
Fire Extinguishers
No single fire extinguisher is suitable for all types of fire.
For this reason, it is vital to understand what is the most likely ‘type’ of fire that you may have on your business premises because choosing the wrong type of fire extinguisher can actually be more dangerous than the fire itself.
At HF Group, we are truly a company well connected. With inhouse electrical and fire and security divisions that can provide you with the electrical testing and fire alarm systems to keep you safe.

Most electrical contractors only work a standard working day shift. If you are (for example) the manager/owner or a hotel, that is not very helpful when your hotel is plunged into darkness at 2am. So knowing there is an Electrical Contractor you can call anytime of the day can be vital to your business.
The benefits of having a 24 hour Electrician
Safety
Any electrical issue should always be dealt with by a trained and qualified electrician. You can’t see or hear electricity so it is vital that any electrical repairs are dealt with by qualified experts who know what they are doing. It may be tempting to try and investigate an electrical problem yourselves (especially if it is late at night) but you increase the chances of electrocuting yourself or starting a fire.
Holidays/Busy Season
Just because it is the Summer Holidays doesn’t mean that you aren’t going to suffer from an electrical problem yet this is so often the time when many electrical contractors are unavailable. As one of the leading electrical contractors in the country, we always have a team of qualified electricians on standby throughout the year.
Response Time
While some electrical problems can wait until tomorrow, there are some that need to be dealt with ASAP. While a traditional electrical company may be fully booked for the next few days, a 24 hour electrician will always be able to arrive on site within a given time.
Peace of Mind
Electrical faults can happen in so many ways. From overloaded systems to rodent damage. Having the peace of mind that the problem will be dealt with quickly is an invaluable asset for a business that depends so heavily on a steady and reliable electrical supply.
How we can help
At HF, we provide manned 24 hour electrical call out services across the UK for businesses looking for urgent electrical repairs on domestic and commercial properties.
At HF Electrical, all of our electricians are fully trained and qualified professionals. We cover everything from faulty and hazardous electrical items to more common electrical repairs.
Sick Building Syndrome (SBS) is the name of symptoms that you can develop because of a lack or effective ventilation system and resultant poor indoor air quality in office buildings and similar indoor environments.
What are the symptoms of Sick Building Syndrome?
The symptoms of sick building syndrome can vary but commonly include:
Headaches
Blocked noses
Runny noses
Dry and itchy skin
Dry eyes
Dry throat
Coughing
Wheezing
Skin rashes
Tiredness
Lack of focus
What are the common causes of Sick Building Syndrome?
There are many causes of sick building syndrome. Some affect people in different ways and others work in a combination and can include:
Poor building ventilation
Poorly maintained air conditioning systems
Dust, Fumes, Smoke
A high number of people in a crowded internal space
How to combat sick building syndrome
Effective ventilation systems are the best way of combatting sick building syndrome. A properly functioning ventilation system helps to deliver fresh air in enough quantity to properly ventilate a working area and create a comfortable internal working environment. Proper ventilation of a building helps to dilute and remove airborne pollutants as well as reduce odours, fume built up and dust.
Natural and Mechanical Ventilation Systems
Depending on the size of the office space, either natural or mechanical ventilation systems can be fitted. While some buildings simply require a natural supply of air to be brought into the working space and a natural exhaust system to remove indoor pollutants, some larger building environments need mechanical ventilation systems to be designed and installed.

HF Group Mechanical Services team of engineers specialise in the design, supply, installation and commissioning of a huge range of ventilation systems for use in domestic, commercial and industrial application.
Ventilation systems are of course an essential part of a buildings heating, ventilation and air conditioning systems (HVAC). At HF Mechanical, we provide a leading ventilation system design and installation service for businesses across the UK.
Covering all of Scotland, England and Ireland through our division offices across the UK, we can undertake ventilation installation and maintenance projects of all sizes and complexity. Whether working with building contractors or directly with the customer, we can work on integrated or standalone ventilation systems.
What to do if water leaks onto electrical light fittings
In the UK, the weather can range from sunny and warm to wet and windy in the blink of an eye.
Which means that storms and heavy rain are a near constant threat. Across offices in the UK, this can frequently mean that rain water penetrates the building interior and you are dealt with the issue of water leaking onto electrical light fittings. So what should you do?
Water acts as a conduit for electricity therefore it is possible to suffer from an electrical shock. Even touching a light switch can actually result in a shock.
On top of this, water stuck in a light fixture can present a fire risk. This is because the water can create a sparking effect leading to a fire.
If you have noticed water coming through the ceiling and it has already been raining for a number of days, there is a high chance that the leak has been steadily letting water in for a long period of time and it has only now reached a point where you have noticed it. This means that above the ceiling, water damage has affected the electrical wiring which itself can create short circuits.
When you notice water coming through an electrical light fitting, the first thing to do is turn off all the electricity. If this is a residential home then you should turn off all the electricity to the entire home. If you are working in a large commercial building, you can turn off the power to that floor (if possible). This will give you time to handle the leaking water.
Move any electrical equipment that could be damaged by water to safety, clean up any mess, place buckets below the leak.
Once this has been handled, you can call our Electrical Services team and take advantage of our Reactive Maintenance Services.

At HF we offer responses that suit your needs, if you are under a PPM contract then there will be set service level agreements in terms of response in place and these could range from 3 hours response up to 3 days depending on what the issues is.

Does your businesses fire alarm system need an upgrade?
You should not wait for a fire to occur before finding out that your existing fire alarm system is not working. Testing a system on a regular basis is important to ensure that this vital warning system is operating properly. But older fire alarm systems can deteriorate and develop issues over the years that set off false alarms which can result in fines. But how do you know whether your existing fire alarm system is in need of an upgrade? Here are some examples to look out for if your businesses fire alarm system needs an upgrade.
Sensitivity Test Requirements
If a fire alarm system does not meet the necessary sensitivity test requirements, it will need to be upgraded. Fire alarm systems can be either too sensitive or not sensitive enough. A overly sensitive system can trigger randomly which can result in fines from the Fire Department. Systems that are not sensitive enough cannot be relied on as a warning system in the scenario that a fire does break out in your business premises.
Renovations and Expansions
As a company grows, its premises may have to adapt to accommodate the growth. These changes may require your fire alarm system to at the very least be modified or upgraded as the location of key businesses assets and personnel move around.
Age
The older a fire alarm system gets, the more it requires system maintenance. Yet despite regular maintenance services, systems can become less reliable and therefore an upgrade may need to be looked at.
Faulty System
If your fire alarm system has simply stopped working then an upgrade may be required. Older fire alarm systems can become un-functional because of dirt/grime build up, rodent damage, tampering or similar issues which prevent the system from operating.

In business, time is money. So having a robust information infrastructure is essential. Data Networking Cabling is a vital part of day to day office transactions. With the reliance on cabling and connectivity proving to be more and more vital as the years go on, having a network cabling solution that works not just today but for the future is an essential part of a businesses operational needs. As the company grows, it is important to get your business data cabling needs right. But what do you need to consider?
What are your current data cabling needs?
Before you can plan out your business cabling needs for the future, you need to understand your current needs. How many end points require connectivity? How much data and information needs to be shared for your business to operate as it is. Once you know this, you can begin to plan out your needs for the future in sync with your businesses growth plans.
Planning for the future
If you have a clear understanding of how the company will grow then you can better understand the data cabling needs for that point. Cabling your business for the present will leave you no room for expansion in the future. Planning and setting out the cable infrastructure needed for the future is both cost effective and helps to create a more seamless transition of growth.
The layout of your office premises
If your business operates from a Victorian Sandstone office building in the centre of town, then you may be restricted to how cabling can be installed. Modern office buildings are better equipped and spaces for growth and data networking customisation. Data cabling can be installed either as part of a full office refurbishment or Partial Office Refurbishment
Moving into a digital world
Video conferencing and in house call centre teams require sufficient voice and data cabling. The 2020 Coronavirus pandemic helped to show businesses that it was possible to operate remotely and looking to the future, it is likely that business travel will be reduced in favour of video conferencing. Planning and setting up your data cabling for the greater need of digital communication has to be considered.
Find out more
In this modern age of super fast communication systems, having a proper network connectivity system that is designed and installed for your business needs is crucial. Internal data cabling networks are a vital component of the day to day running of a commercial business.
If your business is relocating premises, upgrading or expanding your I.T. network or looking to switch from your existing and current data cabling network, we at HF Electrical are perfectly placed to provide you with the high quality network installation services that we have become so well know for.
With every phone and data network installation, comes its own unique challenges so the best way to find out how we can help you with your phone and data network installation and maintenance is to chat to us about your own unique business needs.

Across the UK, the variation in styles of home and the age of construction of these buildings is vast to say the least. From period sandstone buildings over 100 years old to modern brick and steel structures.
And with so many home owners looking for the charm of older buildings and high street shops wanting the high foot traffic locations in the centre of town that commonly means older buildings in the city, they may have to contend with old electrical wiring.
With electrical wiring, unless you open up the walls to have a look at the actual condition of the cabling, you will have no idea whether the building is at risk of fires and electrical problems because of its wiring. It may even be that your properties electrical wiring is simply not up to code.
But what are some of the most common issues that can arise with old wiring in historic buildings in the UK?
Age
There is a general assumption that old electrical wiring is bad because they didn’t know what they were doing; but that is not 100% true. Yes things have advanced a lot since the early days of electrical sockets and wiring in a home, but properly installed electrical systems can stand proud against some modern electrical fittings absolutely fine. It is the age and ‘weathering’ of the cabling that is the bigger problem.
Older electrical wiring can rust, be exposed by rodents, crack and become brittle because of weather and temperature variations etc. Older wiring is around 80 years old or more and was installed sometimes before the first computer had been invented. It is simply not capable of running modern electrical appliances like computers, modern lighting etc. This can lead to cable overheating and become a fire hazard.
Property usage changes
There are some older buildings that were once shops and are now homes and some homes that were once shops. This switching back and forth can mean that electrical installations are simply not up to the demands anymore. A coffee shop for example that was once a residential property may have a commercial kitchen set up that is using the same electrical wiring that the previous residents had. When you have a commercial electric oven, cooking hobs, extractor fan, air conditioning and electric radiators added into the mix, this can put a serious strain on the old electrical wiring already fitted.
How to deal with old electrical wiring
The simple answer is rewiring. HF Electrical provides a catalogue of Installations we can offer ranging from refurbishments to full install on both a commercial and industrial aspect. All works can include just electrical work or we can provide a wider range for ease of the client by providing both Mechanical install and Fire & security.
Our range of electrical installation (and maintenance) services covers:
24 hour emergency call-outs
Commercial and domestic electrical installations
Full house rewires and testing

Every business has unique security needs but whatever your needs are, a common preference of thieves and trespassers is that they like to operate at night and under the cover of darkness.
One of the most effective yet cost efficient methods of site security is with security lighting. While it should also be an accompanying security solution along with a more expansive security system, the simple presence of outdoor security lighting is enough to put off potential thieves.
The benefits of security lighting
Can reduce break in from occurring
Without the cover of darkness, thieves more often than not turn their attention to less secured business premises.
Works in tandem with CCTV and Surveillance Systems
With the presence of lighting systems, CCTV cameras can work better. And the increased chances of being detected is often enough to dissuade potential trespassers.
Sense of Security
Well lit exterior space can create a safer space. In the depths of winter when darkness has generally covered the sky before the working shift is done, having a well lit area around the building premises can offer staff a sense of security.
Motion Detection Lighting Systems
Most security lighting systems operate on a motion detection system. This obviously cuts down on energy bills and may actually save your business money on insurance costs as motion detection lighting systems are a great way of fending off thieves.
Lighting Systems are an easy to install security solution that can help add another layer of security protection to a businesses premises as a way of protecting key assets from theft.
At HF Group, our Fire and Security Division can provide a complete Security Lighting Installation Service along with any and all security system requirements your business may have.
Businesses across the UK must have an effective fire detection system. And if your business premises covers multiple rooms, involves high fire risk tasks such as a restaurant kitchen or an IT server room filled with electrical equipment, then having an effective fire alarm system is necessary.
The risks of a fire in the workplace
Fires are such destructive forces and while it may seem obvious, the dangers of a fire should always be remembered. Some of the most common issue with fires in the workplace include:
Risk to life
Your employees safety should always come first. A proper fire alarm system and the vital seconds it can save in alerting staff to evacuate can truly make the difference between life and death.
Financial Costs
The sooner a fire alarm is raised, the more likely it can be controlled. Damage to a businesses premises structure and assets caused by fire can sometimes be irreplaceable. A functioning fire alarm system can help to reduce the damage caused and the heavy cost of repairs.
Legal Action
In situations where businesses have ‘cut corners’ with their fire protection systems and subsequent injury or death has occurred, the lawsuits and legal costs of legal action can far outweigh the cost saving nature of not having a fully working and effective fire alarm system.
How to tell what type of fire alarm system my business needs.
The first step is to conduct a Fire Risk Assessment. This can help to identify the various potential fire risks in your premises. This can then be used to educate staff on necessary precautions as well as reveal what level and kind of fire alarm system and fire prevention systems you may need.
Our Fire and Security Division can provide you with a complete Fire Risk Assessment Report and recommendations on what level and kind of fire alarm system you should install.
Ensuring your fire alarm system works
There are many ‘DIY’ fire alarm systems on the market but they are an unreliable system that has been known to trigger multiple false alarms which can actually result in expensive fines from the Fire Department because of unnecessary callouts.
Fire Alarm Servicing and Maintenance
Having a Fire Alarm System fitted is one thing. Ensuring that it works and is properly maintained is another. At HF Group we provide year round call outs and servicing for Fire Alarm Systems to ensure that they operate properly 7 days a week, 52 weeks a year.
Across the UK, there are a countless number of swimming pools of all shapes and sizes found in leisure centres, sports facilities, gyms, hotels and private homes.
And the heating of these pools on a daily basis is an incredibly important part of the enjoyment and usability of these swimming pools. After all, if you have ever dipped your toe into the North Sea in the Winter, you will know that swimming in cold water is not that much fun.
But how does a swimming pool get heated?
There are several ways to heat a swimming pool from heat pumps to solar panel options but the most popular type of heating system for heating a swimming pool is with commercial boilers.
A gas boiler can be used to heat indoor and outdoor pools and works in the same way that common residential boilers operate. Only this time, instead of heating your homes hot tap, it heats up thousands of litres of water.
The step by step of heating a swimming pool
The pool is filled with cold water
This water is pumped out of the pool using a pump
The cold water is filtered and then sent to the boiler
The boiler heats the water to the ideal temperature (based on facility specifications and pool size)
The warmed up water is pumped back into the swimming pool
This is an automated loop system that happens continuously to help maintain a constant flow of warm water.
What size of boiler do you need to heat a swimming pool?
The size of the boiler depends on the size of the swimming pool. In the exact same way that the size of your home will dictate what size of boiler you need to heat your house.
Boilers size is measured in kW output. The larger the pool, the more kW you will need.
How long does it take to heat a swimming pool?
Anywhere between one and two days depending on the size of the pool the size of the boiler and whether the swimming pool is indoors our outdoors.
How HF Group can help
Through our Mechanical & Heating divisions, HF Group can provide heating solutions for swimming pools both indoors and out. With years of experience in this sector, our experience and opportunity to tap into a wide range of varied services and associated consultants means that working with HF Group is more than just another service contractor.

Gas Fire Suppression Systems are one of the leading performance solutions for effective fire extinguishing.
Using a combination of inert gasses, vaporised liquids and chemical agents designed to control and extinguish dangerous fires, it is easy to understand why they are such a popular fire control system.
Using a system of fire detector units, an agent storage and delivery system, Gas Fire Suppression Systems are used primarily when water, foam or powder extinguishers are either not able to be used or are not effective in controlling and putting a fire out.
Where are Gas Fire Suppression Systems commonly used?
Computer Labs
Server Rooms
Archives
Libraries/Museums
Scientific Laboratories
Offshore Rigs
Marine Vessels
Electrical/Engineering Facilities
How does a Gas Suppression System Work?
Using a system of fire detector units, an agent storage and delivery system, Gas Fire Suppression Systems are used primarily when water, foam or powder extinguishers are either not able to be used or are not effective in controlling and putting a fire out. They extinguish fire by reducing the core heat of the fire, isolating the fuel source, reducing and cutting off the fires access to oxygen and by reducing the chemical reaction that causes more combustion to occur.
This multi step process is invaluable in providing fast acting fire suppression and is why it has become such a popular choice for fire fighting in Commercial and Industrial premises.
Are there risks associated with the system?
Dealing with a ‘cocktail’ of airborne gases and chemicals will always present risks. The CO2
system is hazardous to health and therefore can only be used in certain environments and mainly in site locations that have a low volume of employees/personnel or ideally none.
The system pumps CO2 into the rooms air to reduce the amount of oxygen in the room as one of the methods of fire control. It cannot be used in (for example) and office space filled with people.

From residential properties, commercial office space and industrial premises. Access control systems are one of the most powerful methods of security used to protect your staff and high value internal assets, stock, equipment and more.
But access control systems are not just a simple lock/unlock system. With modern thermal screening systems and facial recognition, access control systems have many benefits to them beyond simply granting access to authorised personnel and blocking unwanted access to buildings and areas within buildings for visitors and thieves.
Here are 5 key benefits of using Access Control Systems for your business.
1 – Workplace Efficiency
Facial recognition allows access control systems to double up as a clock in/clock out system that allows your business to effectively monitor staff movement, punctuality and arrival time. This can allow you to remove complex manual check in systems and create a better workplace data stream for staff attendance (vital for fire alarm drills and emergency building evacuation).
Thermal screening incorporated into access control systems can also provide an invaluable asset to staff health. After the Covid-19 pandemic, thermal screening has allowed businesses to better track sickness in the workplace. If a staff member exceeds a set temperature, they can be stalled from entering the building and passing on contagious illness to other staff.
Access Control Systems allow employees to move freely through the workplace and can be customised to cover multiple locations within a building or premises. This allows workers to move freely across multi premises with ease.
2 – Cost Savings
Thanks to the advances in smart technology, access control systems can be synced with heating systems and lighting in order to increase efficiency and cut down on unwanted waste energy. Access control systems can ensure that lights are turned off in office space that is empty. The same can be done with heating systems. The long term financial savings of access control systems can truly add up depending on the size of your business premises.
3 – Staff Security
Access control systems can provide great safety benefits. In the event of a fire emergency, the data from Access Control Systems can provide Emergency Response Teams with invaluable information about who is inside a building. This data has saved countless lives already in businesses across the UK.
Access control systems also provide peace of mind for staff as the system will not let intruders in. This helps to create a safe working space for your team.
4 – Replacing Keys
No more jingle gangle of a bunch of keys and no more long waits at a door as you try to remember which key opens which door. Access control systems saves time and removes human error from lost or misplaced keys. Access control systems can operate on key cards, fobs and facial recognition and be be easily activated/deactivated should a key card be lost or stolen or an employee leaves the company.
5 – A security system with room to grow
Access control systems can grow with your business. So you may want to initially introduce an external door security system to allow all staff into the building. This system can then grow with the business so that as you want to introduce discretionary access to areas of the building, you can.
Access control systems can be scaled not just with company growth of facilities size but also with the employee status of individuals within the company.
This flexibility is designed into the system and the varied levels of restriction and access that it can offer allows business to evolve their security system as their demands change. This adaptability makes access control systems a far more appropriate solution to security entry than traditional lock and key security systems.

While some industrial facilities simply require a natural supply of air to be brought into the factory and a natural exhaust system to remove indoor pollutants, some manufacturing facilities need unique considerations to take into consideration when designing and installation ventilation systems.
In a food production centre, ventilation systems need to have air filters incorporated into the system to filter and remove any contaminants that would otherwise be brought into the factory from the supplied air.
Additionally, food processing plants need to have a positive pressure system so that when the doors open, the air within the production facility flows out and prevents the air from outside from coming in.
Beverage processing plants have to deal with the same above mentioned but has extra considerations to deal with. Brewing beer creates a significant amount of heat and moisture. Ventilation systems designed for breweries and similar beverage processing plants need to be able to evacuate all unwanted moisture and heat while confining any harmful odours to the brewery.
Chemical Plants
When it comes to chemical plants, a big consideration has to be placed on the materials used in the ventilation system. The chemicals extracted through the ventilation system can have a serious corrosive effect on the duct system if the wrong material is used. Additionally, if the chemical produced is or can be explosive or highly volatile, then explosion proof fans and non sparking systems should be fitted.
Metal Works/Steel Mill/Smelting factory
In extreme heat environments like those that melt down metal, both wall and roof fan systems with motorised fans that run 24/7 may be required to handle the heat.
Painting Facilities
There are many types of painting facilities but with any of them, the ventilation system should be designed to allow for efficient extraction of internal air space quickly. Curing ovens often found in painting facilities require special ventilation requirements.
Used to control indoor air quality by diluting and displacing indoor pollutants commonly found in industrial facilities, an effective industrial ventilation system requires more than just exhaust fans. Depending on what type of manufacturing and production your facility is involved in, you may need any of the following:
Louvers
A ventilation system with inlet louvers will help to remove unwanted outside elements such as insects, dirt and dust and rain.
Dampers
Used to regulate the airflow or to completely stop the airflow in an emergency.
Silencers
Industrial facilities can be a noisy place but for health and safety, silencers can be integrated into your ventilation system to provide much needed sound relief for your workers.
Air Filters
Helping to clean the air and remove particulates from the air as it passes through the ventilation system.
Dehumidifiers
In manufacturing processes that require dry conditions, dehumidifiers installed into your ventilation system can help to maintain the ideal indoor humidity for your required production applications (especially if they are moisture sensitive).
Fans
Providing a huge range of configuration options from propeller pitch to size, shape and performance. Ventilation systems need to be set up to meet the customers needs and the setup of such systems needs to take into account whether you want natural supply/natural exhaust, natural supply, forced exhaust, forced supply, natural exhaust or forced supply, forced exhaust.
Dust Collectors
Like air filters but built to cope with more heavy duty air particles such as metal, wood and dust particles from manufacturing processes. Dust collectors use a vacuum system to pick up contaminants.

With the 2020 Olympics set the begin, you may not be aware that this years event will mark a first for those who receive the Gold, Silver or Bronze medals.
The metals used to make these medals will come from recycled electronic waste!
In 2020, we created around 55 million tonnes of what is referred to as e-waste. And this total is only set to go up and more and more of us buy electronic products that are designed with shorter life cycles and minimal options for repairs to prolong its life.
So rather than add all those precious metals to landfill like we have done for far too long, the Olympic Games are taking all this e-waste and recycled the Gold, Silver and Bronze to make new medals for the competitors.
But whatever the anniversary may be, they act as a vital marker that allow us to step back and recognise the accomplishments we have achieved in the past whilst laying the foundations for our growth into the future.
