How often should the cartridge be replaced in cartridge or cylinder operated extinguishers?

• A. Once every 2 years
• B. Once every 3 years
• C. Once every 5 years
• D. Once every 7 years

Answer: (C)

The correct choice indicates that the cartridge should be replaced once every 5 years in cartridge or cylinder operated extinguishers. This timeframe is established based on both safety and performance standards outlined by regulatory bodies, which ensure that the extinguishing agent remains effective and that the pressure within the extinguisher remains reliable. Over time, seals may degrade and the effectiveness of the extinguishing agent can diminish, making regular replacement vital for maintaining operational readiness. The 5-year interval allows users to track maintenance easily while ensuring the extinguisher's functionality is restored as needed. Regular inspections should still occur more frequently, typically on a monthly basis, to ensure that the extinguisher is accessible, fully charged, and visually ready for use, but the full cartridge replacement is recommended at this 5-year mark specifically.
