Technician came out to the store to do their annual fire extinguisher inspections. These inspections include updating extinguisher tags for present year/making sure extinguishers are charged and that the store has charged spares ready to go. After conducting a monthly fire extinguisher check at the store, I came across extinguishers missing updated tags and extinguishers missing from their locations. Outside of our fire pump room, was several extinguishers left that the technician did not properly put back where they belong. I also noticed extinguishers inside the pump room that the technician did not properly charge. After making contact with the receptionist to report my findings, a technician was sent back out to our location and everything was updated the correct way.
