Maintenance and inspection of fire extinguishers
The method of inspecting a fire extinguisher is very simple. The first is to inspect the appearance of the fire extinguisher to see if it is damaged. Then check the pressure gauge of the fire extinguisher. There are red, green and yellow areas on the pressure gauge dial. The pointer points to the yellow area, indicating that the internal pressure of the fire extinguisher is too high and there is a danger of self-explosion. Pointing to the green area indicates that the internal pressure of the fire extinguisher is moderate. It can be used, pointing to the red area, indicating that the internal pressure of the fire extinguisher is insufficient and cannot be used normally, which requires a new fire extinguisher.
