performed a routine inspection at a commercial property and identified an issue with one of the fire extinguishers near the back exit. The pressure gauge was in the red zone, indicating the extinguisher was undercharged and potentially unusable in an emergency. I removed the extinguisher from service and replaced it with a properly charged unit from the truck. I then documented the issue, tagged the faulty extinguisher for maintenance, and scheduled it for recharge and testing. I also reviewed the location and ensured all extinguishers on-site were easily accessible and up to code.
