Fire extinguisher, as an effective tool for fighting initial fire, has been widely deployed in factories, offices, schools, hotels, shopping malls, cars, trains and other places. However, the fire engineering installation company believes that because the fire extinguishers are pressure vessels, people's use of fire extinguishers, lack of maintenance knowledge and some of the fire extinguishers are of poor quality, fire extinguishers explosion and injury accidents occur from time to time. Today, the fire engineering installation company said the fire extinguisher explosion. We believe that the main reasons for the fire extinguisher explosion accident are as follows: 1. The fire extinguisher with safety hazards will continue to be used if it is not checked, charged and scrapped in accordance with the prescribed time; 2. 2. The user does not know the safety knowledge of the fire extinguisher, so he or she can disassemble or use the expired fire extinguisher. 3. The company believes that the fire extinguisher placed in a high temperature environment will cause expansion and explosion under heat; 4. Carrying or moving fire extinguishers too hard, resulting in impact and explosion; 5. The company believes that the quality or charging of the fire extinguisher products cannot meet the standard requirements; 6. Some illegal manufacturers collect discarded fire extinguishers and refill them on the market as new ones. The company reminds everyone to take the following measures in the use and storage of the fire extinguisher: the fire extinguisher should be placed in a ventilated, dry, cool and convenient place to use. The company suggests that the fire extinguisher should avoid high temperature, humidity and places with serious corrosion, so as to avoid serious corrosion of the fire extinguisher during the use period and accidents during inspection or use.
