It is applicable to the initial fire of flammable solids or liquids, and is often used in oil fields, oil depots, ships, factories, stores and other places. When it is used for a long time, we will inevitably doubt whether its performance will deteriorate. How long is the validity period of water-based extinguishers? With this question in mind, let's get to know it today!
Validity period of water-based fire extinguisher
The corrosion of water-based fire extinguisher on the cylinder is relatively obvious, and the hydraulic test cycle and maintenance period are also relatively short. The maintenance shall be carried out 3 years after the expiration of the factory, and then every other year, but not more than 3 times in total. It is usually scrapped in the next year after five years. Therefore, according to the industry standard of our country and Article 7 of GA95-2007 Maintenance and Scrapping of Fire Extinguishers, the validity period of water-based fire extinguishers is 6 years.
