After a Class K discharge, what should be done regarding the extinguisher's service status?

• A. Store the extinguisher as-is for later use
• B. Re-activate the extinguisher by quick-test on site
• C. Continue to use until the next scheduled service
• D. Arrange recharging or professional inspection

Answer: (D)

When a Class K extinguisher has discharged, it is no longer charged and its internal components may be compromised. To restore readiness and safety, it must be recharged and inspected by a qualified technician. The device’s tamper seal is broken, the hose or nozzle could be contaminated or damaged, and the cylinder’s integrity needs verification. A quick on-site re-activation or continuing to use it without proper service is not appropriate. Therefore the proper action is to arrange recharging or professional inspection, and if the unit cannot be recharged or repaired, it should be replaced.
