Expiry date of the device’s fire extinguisher

Now it is required to be refilled once a year, whereas it used to be every two years.

The new one is for two years, while the reinstalled one requires replacement once a year

Are there any strict requirements for this? Are there any regulatory documents?

Here too, it’s done every two years: new fire extinguishers are installed, while the old ones are refilled and inspected

Is the date determined by the company’s internal regulations or by some **standardized documents?**

We currently conduct maintenance once a year, and there are relevant standards for this

I need to check; we’re in a high-risk industry, and this was the requirement for standardization in the past

I just checked the Fire Protection Law: \"(3) Building fire protection facilities must undergo a comprehensive inspection at least once a year to ensure they are in good working condition; the inspection records must be complete and accurate, and kept for future reference.\" The regulations regarding the maintenance and disposal of fire extinguishers state: \"1. After each use, fire extinguishers must be taken to a maintenance unit that holds a maintenance license (hereinafter referred to as the maintenance unit) for inspection, so that damaged parts can be replaced and the fire extinguishing agent and driving gas can be refilled.\" 2. Whether used or unused, fire extinguishers that have reached the specified time since their manufacture must be sent to a maintenance facility for a pressure test. 3. Portable and cart-mounted 1211 fire extinguishers, portable and cart-mounted dry powder fire extinguishers. Furthermore, portable and cart-mounted carbon dioxide fire extinguishers must undergo pressure tests and other inspections every five years, and thereafter every two years. 4. Portable and cart-mounted mechanical foam fire extinguishers, as well as portable water fire extinguishers, must undergo pressure test inspections after three years, and thereafter every two years. 5. Portable and cart-mounted chemical foam fire extinguishers, as well as portable acid-base fire extinguishers, must undergo a pressure test inspection after two years from the date of manufacture, and thereafter every year. ” Regional fire inspections are also carried out in accordance with the requirement of annual inspections, with strict standards applied – after all, they need to make a profit as well. There are also some odd requirements – specifying which manufacturers’ fire extinguishers must be used, otherwise you need to provide certain qualifications for the supplier. It’s better to replace it every year for repairs, to avoid trouble

Here, when low pressure is detected during routine inspections of the fire extinguishers, they are sent to the fire department for refilling. Fire extinguishers are calibrated once every 2 years
