Carbon dioxide, carbon tetrachloride, 1211 extinguishers and dry powder extinguishers can be used.
1. First turn off the power supply, then turn off the fire. If the power cannot be turned off quickly, use the above fire extinguisher immediately.
2. Never use acid-based or foam fire extinguishers for electrical fires because the liquid is conductive and can cause an electric shock. This liquid strongly corrodes electrical equipment and is difficult to remove afterwards.
3. When using, sufficient safety distance should be maintained for equipment of 10kV and below, the distance should not be less than 40cm.
A fire extinguisher is a portable fire extinguishing tool. Chemicals are placed in fire extinguishers to put out fires.
Fire extinguishers are part of common fire prevention installations. Hes are stored in public places or in places where fires may occur. Different types of fire extinguishers contain different ingredients and are designed for different causes of fire. Care should be taken when using it to avoid adverse effects and dangers.
Which fire extinguisher can put out real fires?
Fire extinguisher 1211, carbon dioxide fire extinguisher, dry powder extinguisherfor fires in electrical appliances>, Carbon tetrachloride extinguisher.
1. Fire extinguisher 1211
This type of fire extinguisher is relatively less corrosive and will not pollute the environment. It can quickly extinguish the fire. caused by live liquids and equipment.
2. Carbon dioxide fire extinguisher
Because it is a poor conductor of electricity, it is suitable for use in electrical installations below6kV. If it is greater than 6kv, the power supply must be cut off before extinguishing the fire. This type of fire extinguisher can be triggered without polluting the environment and will not cause corrosion or damage.
3. Dry Powder Fire Extinguisher
It is a non-conductive material, so it can effectively extinguish fires caused by gas and electrical equipment. Its advantages are easy storage, rapid fire extinguishing and, above all, low cost.
4. Carbon tetrachloride fire extinguisher
It is a non-conductive product and is suitable for electrical fires below 10kv. However, this product has some degree of toxicity if also inhaled. Many things can be harmful, so use a damp towel to plug your mouth and nose when using it indoors.
Ammonium phosphate dry powder fire extinguishers, bicarbonate dry powder fire extinguisherssodium, halogenated alkyl fire extinguishers or carbon dioxide fire extinguishers should be selected for Class E fires (fires involving electrified objects), but metal fire extinguishers and horn bombs are not permitted.
Class E fires mainly concern fires in generators, transformers, distribution boards, switch boxes, instruments, electronic computers, etc. which are still under tension when they burn. They must be extinguished with extinguishers capable of meeting electrical requirements. insulation performance requirements. For ordinary buildings that only have conventional lighting circuits and lighting fixtures and do not have the above-mentioned electrical equipment, it is not necessary to equip fire extinguishers in accordance with Class E fire regulations.
