What is the incorrect way to deal with the fire of electrical facilities?
The best way must be 2 and 3. Nowadays, dry powder fire extinguishers are generally electrically insulated.

Misuse: 4 carbon dioxide fire extinguisher to extinguish fire.

Reason:

(1) It is easy to wipe static electricity and cause secondary fire (carbon dioxide fire extinguisher is of high-pressure storage type (high-pressure-resistant steel cylinder must be used); One is to store low pressure but use ultra-low temperature cooling equipment to liquefy carbon dioxide gas. When two kinds of carbon dioxide fire extinguishers are sprayed, they are affected by high pressure and the rapid expansion of liquid gasification volume by 760 times, and the spraying speed is particularly fast. High-speed carbon dioxide gas rubs against air to generate static electricity. );

(2) The fire source (i.e. the leakage point of the equipment) cannot be handled.

Wrong usage: 1 splash water to put out the fire

Cause: Water conducts electricity.
