A portable fire extinguisher can help you take control and stop minor fires from becoming major dangers. This active fire protection device uses a compressed agent such as water or carbon dioxide to extinguish or reduce a small fire.
These generally handheld or wheeled devices are designed specifically for small fires, or ones that have just started. Once a fire has become large, a fire extinguisher is an inadequate means of handling the fire. When easily available and properly inspected and maintained, fire extinguishers are a critical defense against fire. Having a working one on hand when the need arises can prevent a minor fire from becoming a dangerous emergency.
There are several fire extinguisher classes. Each class tells you what kind of fire the extinguisher should be used for and the agents it contains.
- Class A is for common combustibles and uses ABC dry chemical, water, foam, halogenated agents, or clean agents.
- Class B is used for flammable liquids and uses ABC dry chemical, BC dry chemical, foam, halogenated agents, carbon dioxide, or clean agents.
- Class C is used for electrical equipment and uses ABC dry chemical, BC dry chemical, halogenated agents, carbon dioxide, or clean agents.
- Class D is used for combustible metals and uses dry powder.
- Class K is for cooking fats and oils and uses wet chemicals.
Inspection Cycles
Fire extinguishers require monthly and annual inspections and maintenance. There are additional tests and inspections required based on your type of fire extinguisher.
- Carbon dioxide and water extinguishers require a 5-year hydrostatic test.
- Cartridge-operated and stored-pressure extinguishers only require a 12-year hydrostatic test.
- Stored-pressure extinguishers require a 6-year inspection, during which all their internal components are replaced
Common Deficiencies
A deficiency is identified during regular inspections when the devices and components do not meet acceptable standards. Here are a few commonly found deficiencies for fire extinguishers:
- Improper type and/or number
- Inadequate distribution throughout the facility
- Blocked or inaccessible fire extinguishers
- Expired fire extinguishers
- Failure to maintain fire extinguishers
- Lack of inspection records
- Insufficient employee training
