Fire Extinguisher Repair and Maintenance

Routine maintenance for fire extinguishers, including 5-year, 6-year, and 12-year inspections, is crucial to ensure that these life-saving devices are in optimal working condition when needed.

5-Year Maintenance (Water, Foam, and K Class Extinguishers)

Water and foam fire extinguishers, commonly used for Class A fires, require a 5-year maintenance interval. This interval includes hydrostatic testing and an internal examination to inspect for corrosion or damage to the valve assembly or other internal components. The extinguisher is also externally inspected for any signs of damage or corrosion. If any issues are found, the extinguisher is repaired, recharged, and returned to service.

6-Year Maintenance (All Dry Chemical Extinguishers)

ABC fire extinguishers typically require a 6-year maintenance interval. During this maintenance, the extinguisher undergoes a thorough examination, internal inspection, and necessary maintenance tasks. However, a hydrostatic test is not typically required for ABC fire extinguishers at the 6-year mark.

12-Year Hydrostatic Test (All Dry Chemical Extinguishers)

ABC fire extinguishers are subject to a hydrostatic test after 12 years of service. This test involves pressurizing the extinguisher’s cylinder to a specific level to check for any leaks or weaknesses. The hydrostatic test helps ensure the integrity and safety of the pressure vessel. If the extinguisher passes the hydrostatic test, it can be recharged and returned to service.

5 Year Hydrostatic Testing (Carbon Dioxide Extinguishers)

Carbon dioxide (CO2) fire extinguishers, typically used for Class B and Class C fires, have a 5-year maintenance interval. This interval involves thoroughly inspecting the extinguisher’s shell, hoses, discharge horns, and valves. The CO2 extinguisher is hydrostatically tested to ensure its pressure vessel’s integrity and recharged.
