Electrical fires are usually caused by the insulation aging of electrical equipment, loose joints, overload or short circuit, etc. Especially in flammable and explosive places, the above electrical wiring hazards are more serious. Fire prevention measures must be taken to prevent electrical fire accidents.
(1) check the operation of electric equipment, check whether the joint is loose, the presence of edm, electrical equipment overload, short circuit protection devices performance is reliable, equipment insulation are in good condition. (2) reasonable selection of electrical equipment. Where there are inflammable and explosive goods, when installing the electrical equipment, the explosion-proof electrical equipment should be used. The insulated conductor must be sealed in the steel pipe. The equipment should be selected and installed according to the grade of explosion hazard. (3) maintain safe installation position. Maintaining the necessary safety spacing is one of the important measures for electrical fire prevention. In order to prevent fire from electrical sparks and dangerous heat, inflammable and explosive materials should not be piled up around electrical equipment that can produce spark and dangerous high temperature. (4) keep the electrical equipment running normally. The spark and dangerous high temperature in the operation of electrical equipment are the important cause of electric fire. In order to control the excessive work spark and dangerous high temperature, ensure the normal operation of the electrical equipment, it should be used and maintained by the personnel who are qualified through the training. (5) the ventilation. Electrical equipment operating in inflammable and explosive dangerous places should be well ventilated to reduce the concentration of explosive mixtures. The ventilation system shall meet the relevant requirements. (6) grounding. The ground in the flammable and explosive dangerous place is higher than the general site. Whether the voltage is high or low, normal uncharged devices should be grounded reliably according to the relevant regulations.
