Carbon Dioxide (CO2) Extinguishers:

Overview:

CO2 extinguishers are predominantly used for electrical fire risks and are usually the main fire extinguisher type provided in computer server rooms. They also put out Class B fires (flammable liquids, such as paint and petroleum).

Overview:

CO2 extinguishers are predominantly used for electrical fire risks and are usually the main fire extinguisher type provided in computer server rooms. They also put out Class B fires (flammable liquids, such as paint and petroleum).

Label Color:

– Black

Use for:

– Flammable liquids, like paint and petrol

– Electrical fires

Do not use for:

– Kitchen fires – especially chip-pan fires

– Combustible materials like paper, wood or textiles

– Flammable metals

How CO2 extinguishers work:

CO2 extinguishers suffocate fires by displacing the oxygen the fire needs to burn.

Types of premises/business who may need CO2 extinguishers:

– Premises with electrical equipment, such as:

o Offices

o Kitchens

o Construction sites

o Server rooms

All work vehicles should also carry a smaller 2kg CO2 extinguisher.

Where to locate CO2 extinguishers:

– Place near to the source of the fire risk and/or near the fire exits.

Carbon Dioxide Extinguishers in Bangladesh:

Carbon Dioxide extinguishers are filled with non-flammable carbon dioxide gas under extreme pressure. You can recognize a CO2 extinguisher by its hard horn and lack of pressure gauge. The pressure in the cylinder is so great that when you use one of these extinguishers, bits of dry ice may shoot out the horn.

CO2 cylinders are red and range in size from 5 lbs. to 100 lbs. or larger. In the larger sizes, the hard horn will be located on the end of a long, flexible hose.

CO2s are designed for Class B and C

(flammable liquid and electrical) fires only.

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. 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.

CO2s will frequently be found in laboratories, mechanical rooms, kitchens, and flammable liquid storage areas. All CO2 extinguishers at USC undergo hydrostatic testing and recharge every five years.
