A fire extinguisher should be maintained and tested:

The choice of maintaining and testing a fire extinguisher every year is grounded in safety standards and regulations that emphasize the importance of ensuring fire extinguishers are in proper working condition. Regular annual inspections help to identify any maintenance needs, such as recharge, physical damage, or compliance with labeling and accessibility requirements. This frequency aligns with recommendations from authorities like the National Fire Protection Association (NFPA), which advocates for yearly inspections as a part of a broader fire safety plan.

While some intervals might seem appropriate, they do not meet the established standards for routine checks to ensure dependability in emergency situations. Annual maintenance not only ensures the extinguishers function properly when needed, but also contributes to overall workplace safety and preparedness.
