What is required when fire extinguishers are initially placed into service?

When fire extinguishers are initially placed into service, a manual inspection is essential to ensure that they are operational and meet the necessary safety standards. This inspection typically includes checking that the extinguisher is in the correct location, determining that it is properly mounted, verifying that it is accessible, and ensuring that the pressure gauge indicates that the extinguisher is fully charged. The manual inspection is a critical part of ensuring that the equipment will perform effectively in the event of a fire.

Other options, while they may pertain to fire extinguisher maintenance or requirements at other stages, do not apply specifically to when they are initially placed into service. Testing in a lab is not a standard initial requirement, and replacing extinguishers immediately is not a necessary step unless there are evident defects. Servicing annually is important for ongoing maintenance but does not pertain to the initial placement in service.
