Why does my fire extinguisher show signs of powder leaking?

If you see loose powder around the nozzle, valve or base, stop using the extinguisher until it has been checked. A leaking or partly emptied extinguisher should not be put back on the wall bracket, and the manuals say it should be refilled by a qualified service company after discharge. fileciteturn0file4turn0file11

1. Keep the extinguisher upright and avoid shaking it. Movement can spread loose powder and make it harder to see where it is coming from.
2. Inspect the valve, nozzle area and cylinder body. Look for a visible crack, a damaged seal or powder collecting near one point.
3. Check the floor and bracket below the unit. Powder on the surface may show that the extinguisher has been disturbed or has discharged slightly.
4. Do not attempt to open the unit or tighten internal parts. The manuals forbid tampering with the extinguisher or removing the valve. fileciteturn0file4turn0file11
5. Move the extinguisher away from living areas if powder continues to escape. Keep it stored safely and do not rely on it for emergency use.

Stop using the extinguisher immediately if any powder leakage continues, the seal is damaged, or the cylinder appears partially emptied. If the issue remains unresolved, contact the retailer or store where the product was purchased.
