The following fire extinguishers can be used 1. Carbon dioxide fire extinguisher: Since carbon dioxide is a poor conductor of electricity, it is only suitable for extinguishing fires in electrical equipment below 6 KV. When the voltage exceeds 6KV, the power must be cut off before the fire can be extinguished.
2. Dry Powder Fire Extinguisher: Dry powder is a non-conductive substance and can be used to extinguish fires in energized equipment.
3.1211 fire extinguisher: 1211 fire extinguisher has no corrosion and has good insulation performance, and can be used to extinguish fires in electrical or oil equipment.
4. Carbon Tetrachloride Fire Extinguisher: Carbon tetrachloride is non-conductive and suitable for extinguishing fires in electrical equipment of 10KV and below.
5. Tip: Foam fire extinguishers should not be used to extinguishprevent fires in electrical equipment, because foam not only destroys the insulation of electrical equipment, but is also conductive.
1. Immediately turn off the electrical appliance, unplug the power plug or turn down the main switch. If you only find smoke coming from the electric spark, the fire will go out after the power is cut. .
2. If combustible materials such as wire insulation and electrical box catch fire, you can use damp quilts and other coverings to smother and extinguish the fire.
3. To prevent the CRT of the TV from exploding and causing injury to people when the TV catches fire, do not use water to extinguish the fire.
4. Do not connect the power supply without repair to avoid electric shock and fire.
5. If a computer catches fire, even if it is turned off or even unplugged, the components insideThe interior of the computer will always be very hot and will always emit flames and produce toxic gases. The fluorescent screen and image. The tube may also explode. How to fix it? Yes: When the computer starts to smoke or catch fire, unplug or turn off the main power switch immediately, then cover the computer with a damp rug or quilt. It can not only prevent explosion. fireworks spread, but also blocks glass fragments from the fluorescent screen. Never pour water on a burning computer, even if it is turned off. This is because a sudden drop in temperature will cause the hot picture tube to burst. Additionally, there will still be residual current in the computer and water splashing. may cause electric shock. Do not lift the lid to look. When extinguishing a fire, to prevent the CRT from exploding and causing injury to people, get close to the computeronly from the side or from the rear.

When you cut off the power supply with electrician pliers or a wooden handle dry ax, you must cut off the phase wires and ground wires of the power supply one by one, otherwise it will cause a short circuit and would lead to a more serious disaster.
7. When fighting a fire, close doors and windows to prevent wind from blowing in and fueling the fire; immediately cover flames with dry quilts and cotton-filled clothing; do not use water or fire extinguishers to spray; electrical equipment to extinguish fire, because electrical appliances will get high temperature if suddenly exposed to water and coldis, they will explode and injure people.
8. After the fire is extinguished, doors and windows should be opened in time for ventilation. It should not be connected to the power supply without repair to avoid electric shock or fire.
First of all, you need to calm down, turn off the power supply, preferably open the circuit breaker, check if there are any relevant objects around, and then ask for help. Decide immediately and evacuate quickly. If there is a threat of fire, immediately put on protective clothing, bedding, etc. soaked and head towards the emergency exit.Hurry up.
