Today we are going to talk about the precautions for the replacement of fire-fighting equipment parts. When the fire extinguisher is repaired, it is often necessary to replace the damaged parts. So how should the parts be replaced?

First. The parts and components should be consistent with the characteristics of the parts and components provided by the original fire extinguisher manufacturer.

Second. During maintenance, seal parts such as seals, rings, gaskets, water-based fire extinguishing agents, and overpressure safety diaphragms of carbon dioxide fire extinguishers must be replaced.

Third. The maintenance organization should replace parts according to the original fire extinguisher manufacturer’s fire extinguisher assembly drawings and replaceable parts list, but the cylinder body cannot be replaced.

Fourth. When the cylinder body is not corroded, additional coating is allowed. The additional coating should be smooth and flat, and cannot cover the nameplate.
