What should you do if you notice paint or chemical leaks on the extinguisher cylinder?

• A. Do not use; remove from service and have inspected or replaced
• B. Continue using after cleaning the surface
• C. Wipe and keep in service if the leak is small
• D. Seal the leak and continue to use

Answer: (A)

When you notice a leak on the extinguisher cylinder, the key idea is that the pressure vessel may be compromised. A leak means the extinguisher may not deliver given pressure in an emergency, and the shell could fail or rupture. Because of that risk, you must remove it from service and have it inspected or replaced by a qualified technician. Do not try to wipe it clean and keep using it, and do not seal the leak or patch it yourself—these actions do not restore safety or reliability. Tag it as out of service and arrange for professional evaluation or replacement to ensure you have a safe, operable extinguisher when needed.
