While some suppression agents reduce the heat of the fire, a CO2 fire suppression system eliminates the oxygen to suppress the fire. When the suppression system detects smoke or fire, it then releases the CO2 agent into the space it is protecting.
What is a CO2 fire suppression system and how does it work?
A fire needs oxygen, fuel, and heat to continue to burn. When the suppression system detects smoke or fire, it then releases the CO2 agent into the space it is protecting. The CO2 level in the space quickly increases as the oxygen level quickly drops causing the fire to be suppressed or extinguished.
How many types of CO2 extinguishing systems are there?
CO2 can be stored in two ways: High-pressure spun steel cylinders (known as HPCO2 suppression systems) Low-pressure light wall refrigerated tanks (known as LPCO2 suppression systems)
Why is CO2 used for fire extinguishing?
Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.
What is CO2 fire extinguishing system?
Carbon dioxide or CO2 is a colorless, odorless, electrically non-conductive gas that is highly efficient as a fire suppression agent. Fike Carbon Dioxide fire protection systems use intelligent, reliable and fast-acting control panels to quickly sense a fire before it can cause damage to property.
What are the two types of fixed fire extinguishing systems?
Safety and Health Hazards: The two most common extinguishing agents used for total flooding applications are carbon dioxide and halon.
What is a CO2 system?
marine. 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.
Is carbon dioxide fire retardant?
The resultant lack of free oxygen dictates that total flooding hazards be evacuated immediately, and carbon dioxide from local application be avoided by personnel. Carbon dioxide is an effective fire extinguishing agent that can be used on many types of fires.
Why is carbon dioxide in fire suppression?
The CO2 displaces the oxygen in the environment which will cause the fire to be extinguished. Fire needs oxygen to continue burning and when the oxygen is being displaced, the fire cannot continue to burn.
How does CO2 affect fire?
Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. CO2s may be ineffective at extinguishing Class A fires because they may not be able to displace enough oxygen to successfully put the fire out. Class A materials may also smolder and re-ignite.
