Maintenance of fire extinguishers
Thread Content
There are time-related requirements for the use and maintenance of fire extinguishers. Some of our dry chemical fire extinguishers have reached their maintenance deadline; however, based on the pressure indicator, they still seem usable. Should we proceed with the maintenance?
It must be maintained to prevent the dry powder from caking. When the dry powder has clumped together, the pressure indicator still shows that it can be used, but in reality it can no longer be utilized.
It must be maintained and replaced. You can look into the composition of the fire extinguisher’s extinguishing agent yourself; over time, it becomes ineffective!
Dry powder fire extinguishers that are approaching their expiration date are all sent by our factory to the fire training site for testing. . .
I have a question: what is the maintenance cycle? 1 year?
I personally think it can be used; as long as the pressure reading is normal, it’s fine to use it. Dry chemical fire extinguishers tend to clump over time when not used. Just shake them a few times before use. That’s how things are in our company.
Pay attention to the ambient temperature. Dry chemical fire extinguishers tend to clump if left unused for a long time; simply shake them a few times before use. That’s how things are in our company.
If a fire extinguisher becomes unusable, how should it be disposed of? Are there professional recycling agencies? It’s best to use a recycling facility in Shanghai.
1. When storing a fire extinguisher, make sure it is not placed in areas where it may be exposed to rain. 2. Invert the fire extinguisher once a month and shake it to prevent the dry powder from clumping together. 3. Check whether the pressure is within the specified range; if not, the container may be corroded and lose pressure, or it may already have been used. 4. Conduct an annual inspection of dry chemical fire extinguishers. If possible, have them pressure-tested again. In fact, if the dry chemical powder is loose but the pressure remains within the specified range, there’s no need to replace the extinguisher. However, during safety inspections, if the expiration date on it has passed, it can lead to complications. Recommendation: Perform regular maintenance, once a month. Regarding the label issue mentioned above, you can contact the filling unit to have it replaced when it expires. A small number of fire extinguishers that have become clogged and unusable are provided for employees to use during annual drills.
