Why should I stop using my fire extinguisher after a small discharge?

Even a small discharge can reduce the pressure or remaining content, so do not keep the extinguisher in service without checking it carefully. The guidance for Smartwares extinguishers says the unit should be replaced directly after each use, and the room should be ventilated well after extinguishing. Treat any used extinguisher as needing attention, even if it only sprayed for a moment.

What to do after discharge

1. Move away from the area and ventilate the room thoroughly.
2. Check the outside of the extinguisher for residue, frost, dents or damage.
3. Look at the pressure indicator and safety pin, if fitted, and confirm whether the unit still appears sealed.
4. Do not assume the extinguisher is ready again just because some powder remains inside.

What the result means

If any part of the extinguisher looks damaged, empty or no longer sealed, it should not be relied on. A used extinguisher can also have an altered pressure reading even after a short release.

When to stop using it

Stop using the extinguisher after any discharge, however small, until it has been checked and is confirmed suitable for future use.

If the issue remains unresolved or safe use is uncertain, contact the retailer or store where the product was purchased.
