we need to pay attention to when repairing fire extinguishers? Next, let Fujie Fire Equipment explain to you:
1. Before disassembling the fire extinguisher, it can only be disassembled after confirming that there is no pressure inside the extinguisher, and safe disassembly methods and necessary safety protection measures must be adopted.
2. When cleaning up residual fire extinguishing agents in fire extinguishers and filling them with new fire extinguishing agents, it is necessary to prevent contamination caused by mixing different fire extinguishing agents.
3. When repairing gas cylinder type fire extinguishers, regardless of whether the gas cylinder is used or not, it should release all carbon dioxide. Each gas cylinder should be subjected to a water pressure test, cleaning, drying, sealing replacement, carbon dioxide filling according to regulations, and airtightness testing one by one.
