How often should cartridge or cylinder operated extinguishers be examined?

Cartridge or cylinder operated extinguishers require an annual examination to ensure they are in proper working condition and ready for use. This annual inspection is crucial for verifying that the extinguishers are fully charged, functioning properly, and that all components, such as the gauge, nozzle, and safety mechanisms, are intact. Regular checks help identify any maintenance needs before a fire emergency arises, thus ensuring the safety of those relying on the extinguishers.

While monthly checks are important for visual inspections, they typically do not cover the comprehensive examination required for cartridge or cylinder operated extinguishers. The other options, indicating examinations every 3 or 5 years, do not align with the recommended practices because they are too infrequent to ensure the equipment remains reliable and effective in an emergency. Regular, annual evaluations are established to maintain compliance with fire safety standards and to provide assurance that the equipment is always operational.
