When an electrical circuit or appliance catches fire, a suitable fire extinguisher must be used to extinguish the fire. Recommended fire extinguishers are:
1. Carbon Dioxide Fire Extinguisher: It uses high pressure carbon dioxide to isolate the air and suppress flames. It is the safest and most effective fire extinguisher. When used, it sprays a white mist of carbon dioxide towards the fire source and is the extinguisher of choice for extinguishing electrical fires.
2. Nitrogen extinguisher: releases nitrogen to reduce the oxygen content in the surrounding air to achieve fire extinguishing effect. It is also a safer option for putting out electrical fires, but it is expensive and rarely used.
3. Dry Powder Fire Extinguisher: Spray dry chemical powder to insulate the air and absorb heat to extinguish the fire. It can also be used to extinguishre circuit fires, but it can produce some degree of conductivity, so please. pay attention to safety when using. Dry powder will leave residue and will need to be cleaned up after putting out the fire.
4. Foam extinguisher: It has certain insulation and fire resistance and can be used to extinguish electrical fires at an early stage. However, the fire protection time of foam is short and the fire extinguishing effect is short. easily lost in large fires. Foam residue should also be cleaned up after the fire has been extinguished.
5. Water extinguisher: Due to the conductivity of water, it is not suitable for directly extinguishing electrical fires and there is a risk of electric shock. Water extinguishers can only be used when the power supply is cut off.
In summary, carbon dioxide fire extinguishersand nitrogen fire extinguishers are the safest and most effective extinguishers for extinguishing electrical fires. Carbon dioxide fire extinguishers are cheaper and should be the first choice. Dry powder fire extinguishers and foam fire extinguishers can also be used, but they need to be cleaned after extinguishing the fire, and the fire protection time is short. Water extinguishers can cause electric shock, so use them with caution.
I hope these tips help you choose the right fire extinguisher during an electrical fire emergency. If you have any other security questions, please don't hesitate to ask. We will provide you with professional and detailed answers. A safe life starts with me!?
