Tennessee Wastewater Operator Practice Exam

How often should fire extinguishers be recharged?

1. Once a month

2. Every year

3. After every use

4. Every six months

The correct answer is: After every use

Fire extinguishers must be recharged immediately after each use to ensure they are fully operational for future emergencies. When a fire extinguisher is discharged, even partially, the extinguishing agent can be depleted, and the pressure may be compromised. Therefore, it is essential to have the equipment serviced and recharged so that it can be relied upon in the event of another fire. While other options might suggest useful maintenance schedules, they do not address the critical need to recharge extinguishers after an actual use scenario. Regular inspections and servicing are vital to maintain the extinguisher’s functionality, but the immediate recharge requirement is necessary to restore its readiness after being deployed.
