How to Choose a Fire Extinguisher

The best fire extinguisher for your business largely depends on what potential type of hazard may occur at the location. Not all fires are the same, and neither are the extinguishers used to put them out. The A, B, C, D, and K ratings on a fire extinguisher correlate with the specific type of fire that piece of equipment is best suited for. The Firehouse Co. will select the correct fire extinguisher size and type needed for your business.


Fires containing ordinary combustible materials, such as wood, cloth, paper, rubber, and many plastics.


Fires with flammable or combustible liquids, petroleum greases, tars, oils, oil-based paints, solvents, lacquers, alcohol, and flammable gases.


Fires that involve energized electrical equipment, such as computers, servers, motors, transformers and appliances.


Fires in combustible metals, such as magnesium, titanium, zirconium, sodium, lithium, and potassium.


Fires dealing with cooking appliances that involve combustible cooking media, such as vegetable or animal oils and fats.

Things To Know

Fire Extinguisher Maintenance Cycle



Annual Inspection

A thorough examination (and repair) of every portable fire extinguisher at your facility. This OSHA & NFPA requirement keeps your business compliant with fire code.


Internal Examination

Specialized testing is required every 5 or 6 years (depending on extinguisher type) to ensure all components are in working order. This includes a complete discharge, thorough internal examination of cylinder and valve assembly, and full recharge.


Hydrostatic Testing

Certain fire extinguishers require hydrostatic testing of the cylinder every 5 or 12 years (depending on extinguisher type). This specialized pressure testing is performed in accordance with NFPA 10 and the manufacturer specifications.
