Why is my fire extinguisher hard to lift or heavier than expected?

A fire extinguisher that feels unusually heavy can still be normal, but it can also mean the unit is not stored correctly or has been affected by moisture, damage or an internal fault. Do not attempt to test discharge just to check it, because these extinguishers are under pressure and should not be tampered with. fileciteturn0file4turn0file11

1. Confirm the model is being handled as a portable extinguisher. These units can weigh up to 20 kg depending on type and size, so two-handed lifting may be needed. fileciteturn0file4turn0file11
2. Check whether the extinguisher is sitting correctly in its bracket. It should be hung on the supplied wall bracket and mounted firmly. If it is loose or awkward to remove, the bracket position may need adjusting by the retailer or installer.
3. Look for signs of corrosion, dirt build-up or impact damage. Rust, dents or a bent bracket can make the unit feel heavier or unbalanced and may also indicate it should not be used.
4. Make sure the extinguisher has not been stored in a damp or very hot place. The manuals warn against heat exposure and physical abuse, both of which can damage a pressurised cylinder. fileciteturn0file4turn0file11
5. Do not remove labels, fittings or the valve. The printed information is important for maintenance and refilling, and the extinguisher must not be modified. fileciteturn0file4turn0file11

Stop using the extinguisher immediately if it appears swollen, damaged, has leaked contents, or you cannot remove it safely from the bracket. If the weight feels abnormal and the cause is not clear, contact the retailer or store where the product was purchased for advice on the next safe step.
