How often must dry chemicals be inspected?

The proper inspection interval for dry chemical fire extinguishers is once every 12 years. This periodic maintenance is crucial to ensure that the extinguishers remain fully operational and effective in the event of a fire. The 12-year guideline corresponds with the requirement for an internal examination, which may involve the extinguishers being disassembled and inspected for any signs of corrosion or damage that could interfere with their performance.

Regular inspections, in addition to the 12-year requirement, include monthly visual checks by the owner or operator to ensure proper placement and condition, as well as annual professional maintenance checks by certified personnel. This helps maintain compliance with safety standards and ensures readiness in an emergency situation.
