Fire suppression systems are used to extinguish or prevent the spread of fire in a building. Suppression systems use a combination of dry chemicals and/or wet agents to suppress equipment fires.
The Main Types of Fire Suppression:-
1. FM200 Gas Suppression system – FM200 fire suppression is also known as HFC227ea. FM200 is a waterless fire protection system, it is discharged into the risk within 10 seconds and suppresses the fire immediately.
How does FM200 fire suppression work?
FM200 is a synthetic/chemical fire suppression gas and extinguishes a fire by removing the free radicals or heat elements from the fire triangle. (Oxygen, Heat and Fuel). The typical concentration of an FM200 system is normally between 7.9% to 8.5%.
2. NOVEC Fire Suppression systems – Novec™ 1230, manufactured by 3M, is a unique fire extinguishing agent. Among the Clean Agents, it has a the lowest atmospheric lifetime of 5 days and zero ozone depletion potential. It is stored as a liquid, which makes it easier for transport.
How does Novec fire suppression work?
NOVEC 1230 DOES NOT Remove or reduce Oxygen! NOVEC 1230 is a synthetic/chemical fire suppression gas and extinguishes a fire by removing the free radicals or heat elements from the fire triangle. (Oxygen, Heat and Fuel). The concentration of Novec 1230 is typically between 5.3% to 5.6% of the room volume.
3. CO2 Gas Flooding Suppression systems – Carbon dioxide (CO2) flooding system. A fixed installation designed to displace the oxygen in the protected space and thus extinguish the fire usually used to fight fires in engine rooms, boiler rooms, pump rooms and holds. The system normally consists of a series of large CO2 cylinders.
How does a co2 fire suppression system work?
The CO2 level in the space quickly increases as the oxygen level quickly drops causing the fire to be suppressed or extinguished. CO2 is a colorless, odorless, and electrically non-conductive gas that leaves no residue behind.
4. Kitchen Fire Suppression System
Kitchen fire suppression systems can be designed to protect a wide variety of kitchen appliances, such as stoves or deep fat fryers. The nozzles for the fire suppression system are installed in the kitchen hood exhaust.
How does a kitchen hood system work? It removes airborne grease, combustion products, fumes, smoke, heat, and steam from the air by evacuation of the air and filtration. In commercial kitchens exhaust hoods are often used in combination with fire suppression devices so that fumes from a grease fire are properly vented and the fire is put out quickly
