What is the validity period of a vehicle fire extinguisher?

[DelIsabela]

The fire extinguishing agent has a validity period of about one year. Below are relevant details about vehicle fire extinguishers: 1. Pay attention to the expiration date: Vehicle fire extinguishers, like those used in daily life, have an expiration date. Those that exceed the usage period should be replaced promptly. After 5 years from the date of manufacture, even if unused, they must be sent to a professional maintenance unit for inspection to ensure safety and reliability. 2. Request relevant documents: When purchasing a small fire extinguisher, besides paying attention to its appearance, you should also ask the seller for the product certification, quality guarantee, and user manual to hold them accountable in case of any issues. 3. Regular inspection: Car owners should regularly check if the safety pin of the fire extinguisher is intact, if the cylinder is deformed or corroded, and if the nozzle is clogged with grease. Additionally, they should frequently clean off dust and clear the nozzle to keep it unobstructed.
