Are private cars equipped with water-based fire extinguishers 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 fire extinguishers and water-based fire extinguishers: 1. Dry powder fire extinguisher: It relies on the chemical inhibition of the volatile decomposition products of inorganic salts in the dry powder to extinguish the fire, or the dry powder particles fall on the surface of the combustible material 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 agent to evaporate the heat of the fire scene, quickly 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, providing both cooling and isolation effects, while participating in fire extinguishing, thereby achieving the goal of 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.
I usually research car safety, and the standard equipment for private cars is a dry powder fire extinguisher. Dry powder has wide applicability and can handle oil, electrical, or ordinary fires, making it very useful in situations like engine oil leaks or short-circuit fires. Water-based extinguishers are only suitable for materials like paper and clothing, but with circuits and gasoline in the car, they are ineffective and slow to put out fires. I once had a water-based extinguisher in my car, and it almost failed me during a minor accident—later, switching to dry powder gave me much more peace of mind. The placement of the extinguisher is crucial; keep it near the driver's seat or in the door storage compartment for easy access. Checking the extinguisher's pressure gauge and expiration date is essential—do it at least every six months to avoid failure. Dry powder may leave some residue, but compared to safety, that minor drawback is negligible. Water-based extinguishers are more eco-friendly, but in a car, dry powder's practicality takes priority.
