What is the validity period of a car fire extinguisher?

[VonMakayla]

Generally speaking, the shelf life of car fire extinguishers is divided into two types: one is the extinguisher cylinder, which has a validity period of 8 years; the other is the extinguishing agent, which has a shorter validity period, around one year. Therefore, car owners should regularly check the condition of the fire extinguisher. Below is a detailed introduction: Types of car fire extinguishers: Currently, the main types of car fire extinguishers on the market are dry powder extinguishers, ultra-fine dry powder extinguishers, carbon dioxide extinguishers, and water-based extinguishers, with dry powder extinguishers being the most commonly used. Dry powder extinguishers use carbon dioxide liquid or nitrogen to spray dry powder for fire suppression. Usage of car fire extinguishers: Car fire extinguishers are equipped with pressure gauges. When the pointer on the gauge is within the green range, it indicates normal pressure and proper functioning; when it is in the yellow range, it indicates excessive pressure, and when it is in the red range, it indicates insufficient pressure, both of which can affect the extinguishing effect and require timely replacement. When using, aim directly at the fire source and spray.
