Seeking advice on the refill cycle for dry powder in dry powder fire extinguishers! ! !

According to the \"GB 50444-2008 Code for Acceptance and Inspection of Fire Extinguisher Installation in Buildings\", dry powder fire extinguishers must be inspected in the fifth year after leaving the factory; subsequent inspections are carried out every two years, and they should be discarded after ten years. However, during routine inspections we usually require that the dry powder in fire extinguishers be replaced annually. We have consulted fire extinguisher inspection agencies, and they said it is due to the shelf life requirements of the dry powder; yet we have not been able to find any relevant standard specifications. We would appreciate guidance from those with expertise at Haichuan.

We originally also had a period of two years; it was only about three years ago that it was changed to one year. The reason for this change is unclear, and currently we still follow the two-year period.

Dry powder fire extinguishers should be inspected five years after leaving the factory, then every two years thereafter, and must be discarded after 10 years. The dry powder needs to be replaced during testing; there is no need to replace it within the testing period.

Shandong has a local standard that requires the powder to be replaced every 2 years

The validity period of the fire extinguisher in a car is one year, and I think it is closely related to the validity period of the dry powder.

The standard specifies testing, but there are no regulations regarding the powder inside. The shelf life of the powder is best known to the manufacturer. Will it be tested after changing the powder? What is the testing method? I’ve always wanted to find out.

After all this talk, no standard or basis has still been mentioned.

Generally, we fill the fire extinguishers in accordance with the instructions indicated on them.

This should vary slightly depending on the region; here, new fire extinguishers are inspected every two years, while those that have been refilled are inspected annually. Since dry powder fire extinguishers are prone to caking, there are requirements regarding the timing of inspection and replacement.

Same question: personally, I think the fire extinguisher has expired. The company that fills them can attach an expiration date label to it, which allows the fire extinguisher to be used for another year. Find the norm.
