As it suggests, a fire suppression system suppresses fire.
We install gaseous fire suppression systems mainly. They’re highly effective in extinguishing and containing the spread of fire.
How do they work? A bit more on that further down, but in the main they release a concentration of gas into a room. This either diminishes the oxygen level in the room or removes the heat from a fire. Either of these two actions means a fire can’t sustain itself and is extinguished. Clever stuff!
How Fire Suppression Works
For a fire to ignite, you need four components: fuel, oxygen, heat and the combustion chain reaction.
Can a fire burn without all four components? No. So by effectively removing one of these elements, the fire will go out.
Most of the common gas fire suppression systems work by removing the heat from a fire so the combustion can’t be sustained.
What are the Different Types of Fire Suppression?
Gas suppression systems are split into two types: ‘chemical’ and ‘inert’.
Chemical fire suppression - works by removing the heat element from the fire so it can no longer burn.
Inert fire suppression - reduces the oxygen level in a room to below 15% to extinguish the fire.
FM200 is a chemical suppression agent that is stored as a liquid and dispensed as a gas. It typically extinguishes a fire in under 10 seconds. That’s pretty fast. FM200 is safe to use in occupied areas as well as it doesn’t deplete the oxygen level of a room.
Novec 1230 is also a chemical suppression agent that works in the same way as FM200. Novec1230 has an extra benefit too though, and quite an important one.
It is environmentally friendly.
It has no ozone depleting potential, so it’s use has no impact on climate change.
Although we ‘hope’ your suppression system never has cause to be triggered, it’s good to know that if it ever is, you’re not contributing to global warming.
IG541 is an inert fire suppression agent. Do you remember the difference? This one works by reducing the oxygen levels in a room in order to extinguish a fire. IG541 also has zero ozone depleting potential and leaves no residue to clean up after discharge.
So which one to choose?
The most suitable type of fire suppression system for your business depends on:
The type of room being protected
The type of fire likely to occur in the room
Whether a room can be effectively sealed
Don’t worry, our Fire Suppression Consultant knows everything there is to know about fire suppression. He’ll come along for a full site survey, which will help them decide the best fire suppression agent for your suppression system.
Which Premises are Fire Suppression Systems Suited to?
This list isn’t exhaustive, but generally the following sites are the most common:
Computer suites and data centres
Operation and Control Rooms
Gas turbine enclosures
Museums, archives and data storage
Room Integrity Testing
Before a fire suppression system can be installed, it’s important that a room integrity test is completed.
Why is it important?
Because it tests the room that’s going to be protected for air tightness. If a room isn’t airtight, when a suppression system is triggered the gas concentration will drop too quickly. And the fire will continue to burn. Kind of defeats the purpose really.
You must get a room integrity test before it’s installed. However, it is also recommended that a room integrity test is completed at least once a year. This is to ensure nothing has been compromised to affect the fire suppression systems capabilities. If there’s any building works or general maintenance on the room, you guessed it, you need a room integrity test!
