“We were told we needed to have a fire extinguisher available.” No one mentioned that it had to be operational and serviced.
We all run into this type of situation. We need to have a piece of equipment to comply with the regulations, but we never service or inspect it for proper operation. What good does this equipment do us if it is not available, accessible, serviceable, operational, etc. Might as well not have it in the first place. If you just need the equipment to check off a mark in your little box, then so be it, but at least make sure you add another box for inspection and service.
