What is Class A vs C fire extinguisher?
Fire Extinguisher Classes
Class A extinguishes wood, paper, and plastic fires. It Class B fights oil, gas, petroleum, etc. fires. Class C fights electrical fires.
It A and C fire extinguishers fight fires with distinct chemicals and procedures.it Class A fire extinguishers work on wood, paper, cloth, polymers, and other solids. These flames produce ash and embers. Class A fire extinguishers employ water, foam, or dry chemical powder. Water or foam extinguishers cool fires, while dry chemical powder inhibits combustion.
Class C fire extinguishers are for electrified electrical equipment fires. These fires have active electrical currents. Class C fire extinguishers use non-conductive ingredients like CO2 or dry chemical powders. Non-conductive substances extinguish fires without electrical shock.
Remember that Class C fire extinguishers may also fight Class A and Class B fires. Water and foam conduct electricity, therefore Class A fire extinguishers are not ideal for electrical fires.
What is the best Class C fire extinguisher?
CO2 extinguishers are best for Class B and Class C fires (flammable liquid and electrical equipment) because they employ a cold discharge to smother and cool the flames quickly.
The finest Class C fire extinguisher depends on many criteria, including the environment’s needs. However, several extinguishers are useful against Class C fires.
Highly suggested is a CO2 fire extinguisher. CO2 extinguishers are non-conductive and residue-free, making them ideal for electrical equipment. They suffocate fires by displacing oxygen. CO2 extinguishers are effective in sensitive electrical equipment or situations where other extinguishing chemicals may damage equipment.
Dry chemical powder extinguishers are also utilized for Class C fires. Monoammonium phosphate or sodium bicarbonate extinguishers stop fire chemical reactions. They work well for electrical fires and other flames.
