Fire extinguishers should be serviced once a year or after any use to ensure they are in proper working condition. This annual servicing is crucial because it allows for a detailed inspection of the extinguisher, checking for any physical damage, ensuring the gauge readings are within the acceptable range, and confirming that the pressure is adequate. After any use, even if the extinguisher was not fully discharged, it is essential to have it inspected and refilled to make sure it is ready for any future emergencies.

Routine annual maintenance, as outlined, is part of standard fire safety protocols and complies with National Fire Protection Association (NFPA) guidelines. This ensures that fire extinguishers are reliable and effective when needed, thus maintaining safety standards in workplaces and other environments.

Options that suggest less frequent service, like every three years, neglect the need for regular maintenance and oversight required to keep extinguishers functional and compliant with safety regulations. The choice indicating service only during inspections by the fire authority fails to recognize the importance of regular checks that should be conducted more frequently by responsible personnel.
