Which is better for car fire extinguishers: dry powder or water-based?

[OJudah]

For car fire extinguishers, it is recommended to use dry powder fire extinguishers, as they are more suitable for vehicles. Below is a brief introduction to dry powder and water-based fire extinguishers: 1. Dry powder fire extinguisher: It relies on the volatile decomposition products of inorganic salts in the dry powder to inhibit fire through chemical reactions. 2. Water-based fire extinguisher: It sprays the extinguishing agent to evaporate the heat from the fire scene, rapidly reducing the temperature of the fire scene and inhibiting thermal radiation. The surfactant quickly forms a water film on the surface of the combustible material, isolating oxygen and providing both cooling and isolation effects, while also participating in fire suppression, thereby achieving the goal of rapid fire extinguishing.
