How should household appliances fire?
After the electric equipment is on fire, it can not be poured directly with water. Because the water has electrical conductivity, into the live equipment, easily lead to electric shock, will reduce the insulation performance of equipment, and even cause equipment explosion, endanger personal safety.Transformers, oil circuit breakers and other oil filled equipment after the fire, water can be sprayed into fog, fire fighting. Because the water mist area is large, the water bead is small, easy to absorb heat and vaporize, and the flame temperature is lowered rapidly.
If only a short circuit due to electrical fire, the electric power switch can be switched off immediately, and the power supply is cut off. If the whole circuit is burned, the main switch must be pulled off and the total power will be cut off. If it is too far away from the main switch and it is too late to pull it off, drastic measures should be taken to cut the wires away from the burning place in the correct way. Do not use hand tools or metal directly access or shear, but should stand on a wooden bench with pliers, insulated handles diagonal pliers and other tools cut wire. The method of cutting off the power before available conventional fire, no fire extinguishers can be extinguished with water.
