How often should fire extinguishers be serviced on a vessel?

Fire extinguishers on a vessel are crucial safety devices that must be maintained to ensure they function effectively in emergencies. The correct practice is to service fire extinguishers at least annually and after any actual use. Regular servicing once a year allows for inspections that check the pressure gauge, ensure hoses and seals are intact, and verify that the extinguisher is in proper working order and easily accessible.

Additionally, if an extinguisher is used, even partially, it needs to be serviced afterward to assess whether it is fully charged and ready for future use. This procedure ensures that the firefighting equipment is reliable and meets safety standards, reducing the risk of equipment failure during an emergency situation.

Other responses suggest less frequent inspections or servicing only after incidents, which would not ensure the reliability of the extinguishers in a ready-to-use state when an emergency arises. Ensuring regular maintenance is key to compliance with safety regulations and effective emergency preparedness.
