How often must fire extinguishers be inspected and recertified by a licensed technician?

The answer is correct because fire extinguishers must be inspected annually by a licensed technician to ensure they are in proper working order and compliant with safety regulations. This annual inspection includes checking the pressure gauge, inspecting for physical damage or corrosion, ensuring that the nozzle is unobstructed, and verifying that the extinguisher is properly mounted and accessible.

This regular maintenance is crucial for the safety of individuals and property, as an inoperable extinguisher during an emergency can have dire consequences. In addition to the annual inspection, monthly checks are recommended for visual inspections by personnel to ensure that extinguishers are not obstructed and are properly positioned, but the formal inspection and recertification must be conducted by a licensed technician once a year.

Every two years or quarterly inspections are not standard practices for fire extinguishers, which is why those options do not align with the requirement established by fire safety regulations.
