When electrical equipment fires or ignites surrounding combustibles, first try to cut off the power supply if it is safe, if it is not possible to cut off the power supply in time; when it is necessary to use fire extinguishing, use non-conductive fire extinguishing equipment to extinguish the fire, such as dry powder, carbon dioxide, 1211 fire extinguisher Do not use a foam fire extinguisher to extinguish the fire. At the same time, it is necessary to maintain a sufficient safety distance between the person and the conductive fire-fighting equipment used and the charged body. Fighters should wear insulated gloves. When extinguishing air equipment such as overhead lines, the elevation angle between the person and the electrified body should not exceed 45°. Moreover, it should stand on the outside of the line to prevent the wire from coming into contact with the human body. If the charged body has been broken to the ground, a certain warning zone should be drawn to prevent the stepping voltage from hurting people.
