When should the fire extinguisher be replaced or professionally recharged?
- A.After any use, even a short burst, and whenever inspection shows low pressure or damage
- B.Only after it has been used three times
- C.At the same time as the engine oil, regardless of use
- D.Never, if the gauge still shows green after use
Correct answer
A. After any use, even a short burst, and whenever inspection shows low pressure or damage
Why
Even a two-second test burst drops pressure and breaks the seal, so the unit is no longer dependable or compliant. Swapping in a fully charged unit is part of finishing the job after any fire event.
