Which statement best describes the recommended approach to checking for leaks or damage on extinguishers during routine inspection?

• A. If damaged, continue use until maintenance visit
• B. Repair minor leaks on-site yourself
• C. Refill if pressure seems low
• D. Do not use; remove from service and have inspected or replaced

Answer: (D)

If you find any sign of leaks or damage on an extinguisher during routine inspection, it should not be used. Leaks or damage indicate the unit’s integrity and reliability are compromised, and the pressurized contents could be released or the valve or seals could fail when you need it most. Because extinguishers are under pressure and contain potentially hazardous agents, repairs or refilling must be done only by trained personnel with the proper equipment. The safest course is to remove the extinguisher from service and have it inspected or replaced by a qualified technician. After professional assessment, it can be repaired and re-certified if possible, or retired and replaced.
