After a Class K extinguisher has been discharged, what should you do?

• A. Tag it as discharged, replace it, and arrange inspection and recharge by a qualified technician
• B. Leave it mounted and reuse after drying
• C. Clear the area and do nothing until the next inspection
• D. Return it to storage for later use

Answer: (A)

Discharging a Class K extinguisher leaves the unit exhausted and the system potentially damaged, so it must be tagged as discharged, replaced, and inspected and recharged by a qualified technician. Tagging communicates that this unit is no longer serviceable and needs professional attention, while replacement or recharging ensures there is reliable equipment ready for the next incident. A professional technician will verify the cylinder, valve, and the associated kitchen fire suppression system if applicable, and restore proper operation. Reusing after discharge, drying and reusing, or simply returning to storage are unsafe because the pressure, seals, and internal components may be compromised and the extinguisher may not perform correctly in a future fire.
