What Type of Fire Extinguisher Should Be Used for New Energy Vehicles?
2 Answers
For new energy vehicles, a portable pressurized dry powder fire extinguisher is the best choice. 1. Introduction: The batteries in new energy vehicles are flammable materials. Any impact, collision, or internal short circuit can cause a fire. Given the potential safety hazards associated with the batteries in new energy vehicles, consumers who purchase such vehicles should not only keep a fire extinguisher in the car but also regularly inspect the battery. 2. Precautions against high temperature and toxic gases after a fire: In addition to high-voltage protection, attention must be paid to the high temperatures following an electric vehicle fire. The burning temperature of gasoline in conventional passenger cars is typically around 500 degrees Celsius, but a power battery fire can reach temperatures of up to 1,000 degrees Celsius. Moreover, burning power batteries release large amounts of toxic gases, such as hydrogen fluoride and hydrogen cyanide.
As a safety consultant, I've handled numerous car accidents, and the key to fire extinguishers for new energy vehicles lies in addressing lithium battery risks. Regular ABC dry powder extinguishers can put out solid, liquid, and gas flames, but lithium battery fires involve high temperatures and chemical reactions, making Class D extinguishers specifically designed for metal fires more recommended. It's most appropriate to keep a 2-4 kg vehicle model in the car, placed in an easily accessible location under the passenger seat or in the trunk. If the car catches fire, ensure everyone safely evacuates to a distance before using it; don't delay escape trying to save the car. Lithium battery fires spread quickly, and extinguishers can only temporarily control them—call the fire department immediately afterward. I remind everyone to regularly check the extinguisher's expiration date and pressure gauge, replacing it annually for extra safety. Choosing branded products like 3M or certified domestic ones offers higher safety. Don't assume electric vehicles are environmentally friendly and overlook this—fire probability is low but consequences are severe.
