What is CO2 fixed fire fighting system?

CO2 flooding system or central bank CO2 system is one of the common fixed fire fighting system installed on most of the ships. It releases carbon dioxide (CO2) in bulk quantity to a protected space (such as engine room, cargo hold, purifier room, pump room, etc.) under fire.

How does the CO2 system put out a fire?

When a fire is detected, the CO2 suppression system will activate and discharge a blanket of CO2 into the area where the fire is present. The CO2 displaces the oxygen in the environment which will cause the fire to be extinguished.

How do you release a fixed CO2 system?

In the CO2 release cabinet, open pilot cylinder valve first. Now open valve 1 for master valve first. Then open valve 2 for CO2 releasing mechanism. Co2 will be released after 60-90 seconds of time delay.

Can CO2 be used to put out fire?

Carbon Dioxide is suitable for us on both Electrical and Flammable Liquid (Class B) Fire types.

What is the disadvantage of carbon dioxide fire extinguisher?

Disadvantages Of Carbon Dioxide Extinguishers As CO2 works by displacing the oxygen around the fire, it is not suitable for outdoor use, or in environments exposed to windy conditions. CO2 is a high pressured extinguisher. Using it on class A fires or class F fires could cause the fire to spread.

What is the procedure followed to enter the CO2 room?

What are procedure of CO2 release in engine room?

  1. Seal engine room.
  2. All ventilation to be closed.
  3. Fuels and boiler within engine room to be shut down.
  4. Evacuate and seal the engine room.
  5. Check out the amount of CO2 required to be injected as per the planned injection information (found in CO2 room and remote station).

How does a CO2 system work?

CO2 extinguishes fire by diluting the oxygen that supports combustion. It is an inert gas that can be used for total flooding or local application. For certain applications, switching to a low-pressure CO2 suppression system can provide the most effective extinguishment and suppression for a facility.

What is the most important thing to do before releasing the CO2 fixed fire extinguishing system?

Close all the entrance doors of the engine room and make sure the room is air tight. 11. Operate the control and master valve in the CO2 cabinet. This will sound another alarm and after 60 seconds time delay CO2 will be released for fire extinguishing.

How long does a CO2 fire extinguisher last?

10 years
CO2 fire extinguishers should be replaced every 10 years.

Why CO2 is the best fire extinguisher?

The carbon dioxide considered the best fire extinguisher to put off fires caused by burning of inflammable liquids such as petrol or oil because carbon dioxide stops the influence of oxygen because it decreases the oxygen present in that fire which leads to the fallout of fire.

When should you not use a CO2 fire extinguisher?

Carbon dioxide fire extinguishers, when used in the right circumstances can save lives. However, it would be dangerous to use a carbon dioxide fire extinguisher when dealing with flammable gases, cooking oils and fats, or in a confined space.
