Fire extinguishers expire and they do this for a few different reasons. One common way is that, over time, the seal on the neck will weaken and allow compressed gas to escape. Extinguishers that have lost much of their pressure will not operate. Pressure within an extinguisher can be conveniently checked through a pressure gauge. “ABC” class extinguishers (ammonium phosphate) have the tendency to fail due to solidification of the chemical in the canister base. Our service technicians can delay this process. Most extinguishers that have expired, especially those designed for commercial use, can be refilled and resealed. Unfortunately, an expiration date cannot be fully trusted and there is no foolproof way to know if an extinguisher is no longer functional. That is due to the extremely destructive potential of fires and the relatively low cost.
