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

Both are acceptable, depending on the owner's needs. Dry powder extinguishers are fast-acting, effective, affordable, cost-efficient, and widely applicable, but they produce significant dust and can be somewhat challenging to operate. Water-based extinguishers are dust-free, prevent suffocation, offer excellent fire suppression, and are non-toxic and eco-friendly, but they are more expensive. Each type has its own characteristics and is suitable for vehicle use; choose based on specific requirements. Storage locations: 1. Keep within easy reach: It is recommended to place a fire extinguisher within easy reach, such as a portable aerosol extinguisher in the cabin for emergency use. 2. Secure placement in the trunk: Traditional dry powder and carbon dioxide extinguishers are larger in size, and their movement during high-temperature driving or vehicle bumps may pose an explosion risk. 3. Horizontal or vertical placement: Dry powder extinguishers can be placed either way, but carbon dioxide and water-based extinguishers must remain upright. These three types are all stored-pressure extinguishers, while aerosol extinguishers do not have these concerns.
I recommend dry powder fire extinguishers for private cars as they are more effective against common vehicle fire risks. Car fires are mostly caused by engine oil line issues or electrical short circuits, making water-based extinguishers unsuitable: spraying water may spread the flames or cause electric shock, whereas dry powder can extinguish Class A, B, and C fires, including oil, electrical, and ordinary combustibles. I've used a car fire extinguisher to handle minor incidents—once when a neighbor's car engine started smoking, the dry powder put it out immediately; water-based ones in similar scenarios actually caused bigger flames. From a safety perspective, dry powder extinguishers are compact and easy to store in the trunk, requiring only an annual pressure gauge check. Choose an ABC-rated dry powder model, 2kg in size is sufficient, and don’t overlook training—staying calm during a fire can save lives.
