What specifications should the fire extinguisher meet during inspection?

The specification that the fire extinguisher must be properly filled and in the green is crucial for ensuring its functionality in an emergency. This means that during an inspection, the gauge must show that the extinguisher is fully pressurized, which is typically indicated by a green marker. A properly filled fire extinguisher indicates that it is ready to be used effectively, should the need arise.

This aspect is essential because an extinguisher that is not adequately filled or is in the red zone may not operate effectively, leading to a failure during a fire emergency. Regular checks of the fire extinguisher ensure compliance with safety standards and enhance the safety of the vehicle and its occupants.

While other factors like being easily accessible and having the appropriate rating are important, they do not substitute the necessity for the extinguisher to be properly filled and operational. If the extinguisher is not in the green or filled properly, it may not work at all, which is why this specification is paramount.
