CO 2 extinguishers are designed for Class B and C (flammable liquid and electrical) fires only. CO 2 is not recommended for Class A fires because they may continue to smolder and re-ignite after the CO 2 dissipates. Never use CO 2 extinguishers in a confined space while people are present without proper respiratory protection.
Why do firefighters use pressurised cylinders?
Conversely, pressurised cylinders are an integral part of a firefighter’s arsenal. A breathing air gas cylinder forms part of the standard firefighter’s SCBA (Self-contained breathing apparatus) equipment, enabling the firefighter to breathe in hazardous, dangerous environments, for up to 30-35 minutes at a time.
How to choose the right cylinder for fire-fighting?
When it comes to choosing the right cylinder for fire-fighting, there are a few key differences. First, the design emphasis is on heat and flame-resistance, instead of cost. This increased fire-resistance enables systems to perform at the scene of fire, in hazardous environments, without endangering the firefighter.
