After using a fire extinguisher, what should be done?

• A. Fully recharged or replaced
• B. It can be used again without service
• C. Should be discarded if empty
• D. Recharged only if a leak is detected

Answer: (D)

After using a fire extinguisher, it must be recharged or replaced by a qualified technician. Discharging the extinguisher lowers both the amount of extinguishing agent and the internal pressure, so it’s no longer ready for another emergency even if it appears untouched. A used unit should be taken in for service promptly to recharge the cylinder, restore the pressure, and check for any damage or leaks. If the unit cannot be safely recharged or is damaged, replace it. Follow the manufacturer’s guidance and applicable safety standards for maintenance and inspection.
