After a period of time these extinquishers need to be discharged and the tanks tested much like recertification of a propane tank. I have been gone from this so long I do not remember what the time period is.

From what I can tell off the internet, dry chemical extinguishers need to be hydrostatically tested every 12 years and internally inspected every 5 years, at least in a commercial setting. I once took an extinguisher into a local shop to get tested and it was quite expensive. They are supposed to be visually inspected monthly. I don't like that the Kidde extinguisher being replaced doesn't have a gauge on it so you can't tell if it is properly charged. So what should be done in an RV? Replace every 5 years, or 12 years or?
My dad once had one of these fire fighting "grenades" in our house. They were used up until about the 50s and were filled with carbon tetracholoride which is very toxic.
