Here, in this article, I’m gonna show you the exact method of how you can refill the Fire Extinguisher.
Let’s get started.

First, check the manual for your fire extinguisher to find the proper procedure for depressurizing it. This usually involves holding the extinguisher vertically and slowly squeezing the discharge handle until the pressure gauge reads “0” and nothing comes out when you squeeze the handle.
- If you are using a dry chemical extinguisher, depressurize it by draining the contents into a dry chemical off recovery system or a general discharge bag.
- You will also need a special recovery system to drain and refill clean agent fire extinguishers such as Halon extinguishers.
2. Wipe the exterior of the extinguisher with a solvent-free cleanser.
