Posted By MICHAEL T Can someone tell me what the fire extinguisher guidance is on class C fires (gas) ie how many / capacity per area? Regards Mike

Posted By MICHAEL T I have read that for a class A fire risk (solid materials such as wood paper, textiles), the provision of one water based extinguisher is required for every 200 square metre of floor space. My question is: If it is a class C fire risk (Gas)the provision of one powder or CO2 extinguisher is required for every (X) square metre of floor space. And what capacity would these extinguishers need to be?

Posted By D. Hilton Also Consider that you should be providing PFE according to the fire load and there may be cases where the provision of X number per floor area is grossly inadequate. In addition, consider that a number of extinguishers have a different fire rating and are not therefore equal.

Posted By D. Hilton Steve The post did not ask for the procedure to be followed in the event of fire and in actual fact depending on circumstance it may well be more appropriate to call the emergency services

Posted By Peter Zunda Not that it appears relevant here, but for advice, there is one scenario where fire extinguishers are required to be present - LPG cylinder storage.

Posted By Peter Zunda Don't want to be appear argumentative but, to be correct, LPG cylinder storage requires dry powder extingushers, for Class C, to be provided as well as water supplies as per CoP7.

Posted By Larry Dry powder will suffice for your basic "A" rating (many are rated at a factor of x3 above water extinguishers) and they are fit for purpose for "C" class fires (providing that you also knock off the gas flow), but there are other issues associated with the powder such as: Asthma attacks. Laxatives. Damage to electrical appliances. A complete and utter mess. Compressed powder. I would love to be of some real assistance as I (think that I) know in my mind what you need. However, without a site visit there is no way I am going give advice on that topic here. So, I am very sorry indeed. Anyone who does give such advice without eyeballing all of your hazards and associated risk factors is a little bit of a fool. My advice is get your boss to invest in some training (ie NEBOSH Fire Certificate) for you. Or pay someone to do a suitable and sufficient fire risk assessment in accordance with the requirements of the RRO (assuming that you are UK based). I accept that that is not the answer to the question that you asked. But under the circumstances its the best that I can do for you.....Keep on smiling.

Posted By Mark Eden Michael First rule of thumb involving a gas fire is to isolate the fuel supply i.e. turn the gas supply off. To extinguish a gas fire can lead to forming an explosive atmosphere that could ignite with devastating effects. Once the gas / fuel has been cut use your extinguisger to put out any secondry fire - water foam or dry powder. The fire service should be called no matter how small a fire, particularly if any form of cylinder is involved. They will normally set up a 200 meter cordon and drench cylinders for 24 hours, for very good reason - if you have seen a cylinder explode then you won't argue. This came about from research carried out by the HSE Lab.
