The rising popularity of gas suppression fire prevention systems
We’ve seen a growing interest recently in gas suppression fire prevention systems. These systems are far better at limiting the damage to equipment and possessions when a fire breaks out. This is because traditional fire prevention systems typically use water or foam to suppress the flames, and this can indeed damage items such as electrical goods, fabrics and paintings.
Gas suppression systems – the science bit!
Gas fire suppression systems have been around since the early 2000s. In essence, when a fire is detected, the system releases gases to reduce oxygen and stop the fire in its tracks.
One such approach uses inert gases, which reduces oxygen in the location to below 15%. This is because fires need more than that percentage to burn. In case you’re wondering, the air we breathe has approximately 21% Oxygen and yet we only need 12% to survive. By reducing the oxygen to below 15% the system, stops the fire but ensures it is safe for humans to enter the location afterwards.
The inert gas typically used in these systems is Inergen. This is naturally occurring and contained in the air we breathe.
Practical uses
Gas suppression systems have been popular for locations with extensive electrical equipment, such as Data Centres, Server Rooms, Healthcare equipment rooms and other IT-related sites. They are also being utilised by organisations with priceless/heritage objects such as museums, the antique and fine art sector and heritage properties.
More recently we’ve seen them gain popularity in the household market. For example, we were able to help a client who wanted a fire suppression system to protect his fleet of luxury cars. The 31 cars were housed in an underground car park in their home and they wanted a fire suppression system which would extinguish a fire, but not damage the vehicles in any way. Conventional systems using water or foam were clearly not suitable. We therefore designed and installed an inert gas suppression system which, when activated, would leave the vehicles unscathed.
The benefits these systems bring
Working in tandem with a fire detection system, gas-based fire suppression brings a number of significant benefits. As well as halting the fire in its tracks, it can minimise the damage involved in doing so, which means there is usually very little clean up or residue to deal with after the fire has been put out.
These systems are also harmless to the people on site and the property’s features and equipment. They react within seconds to extinguish a fire and this means reassuringly fast fire protection. It also means the property will experience minimum down-time and can quickly resume normal life/business soon after a fire. One final point to note is that both inert gas and clean agent systems are safe for the environment and have zero o-zone depletion potential.

Glow in the dark technology takes on a new dimension in fire safety
Emergency lighting is widely used as a secondary lighting source that switches on automatically when a building’s normal power supply disrupted to the primary lights. In the case of a fire within a premises, it can be really helpful in facilitating a safe evacuation.
Introducing Photoluminescent strips
One criticism of emergency lighting, however, is that the lights are usually located on the ceiling and, in the case of a fire, the smoke rises and collects smother all lights both primary and secondary. As a result of this concern, we’ve recently seen businesses show an interest in Photoluminescent strips.
Photoluminescent materials were originally designed to complement existing emergency lighting systems. Advances in technology and improvements in their light intensity now mean that, in many circumstances, they can replace secondary electrical/battery emergency lighting altogether.
Photoluminescent fire evacuation and guidance systems
We work with photoluminescent specialists Ecobrite Ultra who have devised evacuation/guidance systems which do not require electricity. The intensity of light and glow from the photoluminescent (glow in the dark) materials used, are making them a popular choice to signpost exit routes.
The strips and photoluminescent signage can be set at waist level or lower and so create a guidance system should ceiling lights get obscured by smoke or fail. As part of a system, lifesaving appliances and fire-fighting equipment can be signposted with the photoluminescent materials so, in the case of an emergency, they are easy to locate.
Lifespan and maintenance
The strips typically have a 10year life span and unlike electrical lighting do not require a regular maintenance programme. The intensity of the light in the materials has also been proven to be visible to those with impaired vision and Ecobrite Ultra is doing a lot of work with the RNIB.
Want to know more?
Photoluminescent materials can be used both inside and outside a building (for example to signpost external fire safety assembly points). If you would like to learn more about integrating them with your fire detection please contact our team on 01483 791500 or email sales@absolutesecurity.co.uk.
A reminder of employers’ responsibilities for fire safety
When it comes to fire safety, businesses have a duty to keep their employees safe and it’s wise to check that, as an employer, you are complying with your responsibilities under The Fire Safety Order 2005.
Business fire safety obligations
Each business should have a designated ‘responsible’ person for the purpose of fire safety. They should:
- Regularly undertake and review a fire risk assessment of the business premises – this should take into account fire hazards (fuel, ignition and oxygen), people’s location around the premises, risks (of a fire starting, risk to people, fire hazards and obstacles for a fast and smooth evacuation).
- Inform staff about the risks identified
- Put in place, and maintain, appropriate fire safety measures – such as equipping a fire detection system, making sure there is protection if flammable or explosive materials are used or stored and ensuring there are accessible exit routes
- Create and publicise within the business a plan for an emergency
- Equip staff with information, fire safety instruction and training
Local fire and rescue authorities have the right to inspect premises and can issue fire safety notices with changes your business needs to make in relation to fire safety. If you do not follow the current UK fire safety regulations you could be fined or sent to prison.
The government has produced an excellent guide for businesses about how to comply with fire safety law. See – Regulatory Reform (Fire Safety) Order 2005: a short guide to making your premises safe from fire
In the guide fire precautions recommended to businesses include:
- A fire-detection and warning system which is able to warn people in all circumstances
- A means of fighting a small fire in the form of multi-purpose fire extinguishers with a guaranteed shelf life. Typically there should be 1 extinguisher for every 200 m2 of floor space and at least one extinguisher per floor.
- Designated safe routes for people to exit the premises – ideally there should be more than one route and stairways, corridors and areas near fire exits need to be clear of obstructions and flammable materials
- Suitable fire exit doors which do not need a key or specialist knowledge to open them
Other fire safety measures
It is also sensible to consider these other fire safety measures as part of your planning:
- Emergency lighting or photo luminescent strips which can guide people to fire exits if the normal lighting electricity source fails
- Fire safety signage pointing the quickest and safest exit routes
- An ongoing management process to ensure fire safety systems in the business are regularly checked and re-assessed
- A regular training programme to ensure staff are fully knowledgeable of fire risks in the premises and the procedure to follow if a fire breaks out.
When it comes to purchasing fire safety equipment and services, the Fire Industry Association, is a good source of knowledge for the relevant British Standards. The information they provide can help you to select equipment which meets the latest safety standards. The FIA can also guide you on its accredited members for selection and installation of fire equipment.
