Fire extinguishers are the most basic and most frequently inspected fire protection device in commercial buildings. NFPA 10 defines what types you need, where they go, and how often they must be inspected. Here's what Oklahoma City businesses need to know.
Most commercial buildings need Class ABC extinguishers for ordinary combustibles, flammable liquids, and electrical equipment. Restaurants with cooking equipment also need Class K wet chemical extinguishers for grease fires. Specialized facilities may need Class D for combustible metals or clean agent extinguishers for sensitive areas.
The extinguisher type must match the hazard. Using the wrong type can be ineffective or dangerous.
NFPA 10 and the International Fire Code require extinguishers to be mounted, accessible, and located near exits and hazard areas. The maximum travel distance to an extinguisher depends on the hazard class — typically 75 feet for Class A hazards.
Extinguishers must not be blocked, buried, or obstructed. They must be visible or clearly marked with signs.
Monthly visual inspections are required and can be performed by trained building staff — checking that each extinguisher is in place, charged, and unobstructed.
Annual certified maintenance must be performed by a licensed technician, who inspects, services, and tags each unit per NFPA 10. Internal maintenance is required at 6 years, and hydrostatic testing at 12 years for most types.
