Should private cars use water-based or dry powder fire extinguishers?

Both have their own characteristics and are suitable for vehicle use. You can choose according to your specific needs. Below is a detailed introduction to dry powder and water-based fire extinguishers: 1. Dry powder fire extinguisher: It relies on the chemical inhibition reaction of volatile decomposition products of inorganic salts in the dry powder to extinguish fires, or the dry powder particles fall on the surface of combustible materials to isolate oxygen and extinguish the fire. Dry powder fire extinguishers are fast and effective, inexpensive, cost-effective, and widely applicable, but they produce a lot of dust and are somewhat difficult to operate. 2. Water-based fire extinguisher: It sprays fire-extinguishing agents to evaporate heat from the fire scene, rapidly reducing the temperature of the fire scene and inhibiting thermal radiation. Surfactants quickly form a water film on the surface of combustible materials, isolating oxygen and providing both cooling and isolation effects while participating in fire extinguishing, thus achieving rapid fire extinguishing. Water-based fire extinguishers are dust-free, anti-suffocation, have good fire extinguishing effects, and are non-toxic and environmentally friendly, but they are more expensive.
