Which Type of Fire Extinguisher is Suitable for Vehicles?

[DelCamille]

Vehicle fire extinguishers use dry powder fire extinguishers. Introduction to Dry Powder Fire Extinguishers: The extinguishing mechanism of dry powder fire extinguishers is chemical inhibition, which interrupts the chain reaction of combustion. They have a high fire extinguishing rating, comprehensive functionality, rapid extinguishing capability, electrical insulation properties, and good low-temperature performance, making them particularly suitable for use in factories, warehouses, and vehicles. The drawback is that dry powder extinguishing agents are not resistant to re-ignition. Due to their price advantage, most vehicles are equipped with portable stored-pressure dry powder fire extinguishers. Validity Period of Dry Powder Fire Extinguishers: The validity period of vehicle fire extinguishers is generally two years, though it may vary depending on the type. If there is no expiration mark, the pressure gauge's needle in the green zone serves as the indicator. When the needle on the pressure gauge of a vehicle fire extinguisher reaches the red zone, it indicates insufficient pressure in the extinguisher.
