Posted By Lorraine Shuker Not in the trade but studying this topic at the moment for Dip and my study notes detail what should be checked for each type of extinguisher. I can send you a copy if you like ~ email me

Posted By Paul Cook Annually (basic service): Stored pressure extinguishers: (those with dial type gauges located on headcap) Inspect for damage / corrosion, Test gauge for integrity (ensure not stuck), Check instructions visible / in tact, Ensure hose/nozzle is free of obstructions, weigh extinguisher and compare with previous year for any weight loss, check to ensure agent isn`t caking inside powder extinguishers (invert and listen for rain noise!) record data on record label / tag Gas cartridge operated: As above but remove headcap and check-weigh gas cartridge. Check interior for corrosion, lifting lining etc. 5 Yearly. Discharge test and recharge all extinguishers, complete remaining items as per basic service ( label, instructions etc). *Carbon dioxide Discharge test required after 10 years (i think) and hydraulic test (stretch test) on cylinder / new valve assembly also after 10 years. Water based extinguisers with low freeze additive may require refills at more frequent intervals. As stated already, service should be by competent persons in line with BS 5306. If you are unsure contact FETA

Posted By Raj Singh RSO In 1998, there was a fatal accident involving the use of a fire extinguisher. The accident killed someone who was trying carry out works safely. He victim was a fire-watchman and had spotted a small smoldering fire. He tried to put the fire out using a fire extinguish. Part of the bottom of the extinguisher cracked open hitting the victim in the chest. Apparently water had entered the rubber lining at the bottom of the fire extinguisher. The rubber was the rubber protective foot that was supposed to keep the extinguisher bottom dry. And the irony of it is that it was the rubber protective foot that had caused the corrosion, which in turn caused the crack, in turn killing the victim.

Posted By Frank Hallett Thank you for the correction Peter; I can only plead haste over proof-reading. The introduction of the TPVD has clarified a great many of the issues relating to such pressurised devices as fire extinguishers which were earlier classified under the PED as relevant pressure vessels; but, because it doesn't obviously have any links outside transport in the UK thanks to the way that TPV's have been incorporated into road & rail transport of hazardous goods, a great many providers of fire extinguisher maintenance & testing services have failed to recognise the requirements. Ultimately, you will get what you contract for; so read the small print and see what the provider doesn't do before assuming that they will do everything! Frank Hallett
