FIre Suppression

Our uniquely designed systems are one of the most effective ways to protect your business from fire.

Fire Suppression Systems are ideal to use to extinguish fires with minimum damage to the property. Available are a wide range of fire suppression systems including CO2, synthetic, water based and inert gas systems each ideal for a specific location or application. All of our equipment is manufactured to the appropriate European and British Standards.

If your looking to have a fire alarm installed in your premises then our specialist fire alarm engineers can help. Our system design will be completely bespoke to your premise. All our designs are completed in line with British standard BS5839-1:2013 and the Regulatory Reform Order (2005).

When it comes to installing your new alarm system we’ll work around you. We’ll book in your installation on a day that suits you and aim to install it discreetly with minimal disruptions to your business. Our engineers are BAFE and NSI Gold certified so you can be sure of a quality and professional service.

British Standard BS5839-1:2017 states that your fire alarm sysyem should be serviced every 6 months.

Our engineers can service any new or existing fire alarm  system in your premsies. Working around you and your staff our engineers will carry out all servicing without disturbing the day to day running of your business.

Sprinkler Systems

Sprinkler systems, also known as watermist, distribute very small droplets of water to create the maximum cooling effect on a fire. Such systems are based on the well-established principles of hydraulic technology. The water is stored in tanks or cylinders and pipes take the water to areas where it might be needed. Spray heads discharge the water in the form of water mist. The tiny droplets create a large effective cooling surface area of the fire and surrounding volume. The high speed of the droplets means they can penetrate the hot fumes and reach the combustion area. If water is unsuitable (usually due to its electrical conductivity) then a foam agent may be added.

Sprinkler systems work in 3 complementary ways:

Cooling – water spray in droplets of micron size produces a large surface area for heat absorption. Once in contact with hot bodies and gases, these droplets turn to vapour absorbing a large quantity of heat equivalent to 540 calories per gram.

Smothering – the water in its vapour state occupies 1600 times more volume than as a liquid and displaces an equivalent volume of oxygen, thus creating a smothering effect. If both the water vapour generated and the temperature in the hazard is high enough, the concentration of oxygen can fall drastically in the whole room.

Attenuation – the mist cloud generated in the enclosure absorbs a large part of the radiated heat, thus protecting the adjoining risks.

CO2 Fire Suppression Systems

Carbon dioxide systems has been used in fire fighting for over 50 years. It is generally specified in locations where people will not be working since it is hazardous to humans in the concentrations deployed by fire suppression systems. Since there are no chemical residues left after use, CO2 systems are suitable for food industries and other situations where contamination is to be avoided. A further advantage is the low cost of refilling the storage cylinders.

CO2 physically extinguishes fires in two ways. Firstly, it decreases the oxygen level in the enclosure to below the level where combustion can be sustained. Secondly, the gas absorbs heat and cools the fire down.

When dealing with the protection of occupied areas consideration should be given to the fact that if CO2 is inhaled, even at low concentrations, it may lead to asphyxia. Under required safety precautions, CO2 has been effectively applied for over 50 years to protect areas such as transformer rooms, generator enclosures and electrical hazards, also for local application requirements such as printing machines and laminators.

Synthetic Gas Fire Suppression Systems

These systems store the extinguishing agent as a liquid and is super pressurised with Nitrogen. Due to the efficiency of the agent less space is taken up by the cylinders and also means that clearing up after a fire is relatively straight forward. The gases used are approved for Class A and B fires and are suitable for critical risk areas and occupied areas. The synthetic systems are installed around the world in a variety of locations from computer centres, gas turbine enclosures, power stations and data storage sites.

Inert Gas Fire Suppression Systems

Inert gas systems were developed to avoid the use of high GWP halocarbon agents and to allow gas systems to be used in areas where people may be working. The gas mixtures extinguish a fire whilst still allowing enough oxygen to be present in the room for people to breathe as they make their escape.

Inert gases physically extinguish fires by decreasing the oxygen level in the enclosure from 21% to below 15%, meaning that most fires are unable to continue combusting. Inert gas has been effectively applied for many years to protect areas such as transformer rooms, archives, electrical hazards, record stores and computer rooms.

FAQ

How do I know which suppression system I need?

What type of fire suppression system you need will depend on a number of different risk factors unique to your business. Your fire risk assessment will outline these risk factors and inform you of what extinguishers you need and how many. If your still unsure our Fire Protection Consultants will be able to help you.

How often does my suppression system need servicing?

Currently, British Standards states that your fire suppression system is serviced regularly by a competent person. We recommend that you get your suppression system serviced once a year.
