Posted By LynneR Bottled Gas Storage Small Storage/ Display (in shops etc/ up to 70kg) No more than five bottles should be allowed on display with total contents no more than 70kg. Bottles larger than 20kg should not be displayed in shops eg 47kg cylinders If the shop is below residential premises then no more than 15kg should be stored/ displayed. No more than four bottles should be connected for demonstrating at any one time (total weight no more than 50kg). Do not display on staircases, near emergency exits or near to flammable materials. Bottles must be treated as FULL unless they are dummy bottles or have been certified as gas free. Only five cylinders are allowed - even if some of them are empty. Storage up to 400KG Quantities of LPG greater than those described above must be kept in a properly constructed store. The storage area should be at least 1m from a site boundary, building etc. unless a fire wall is provided. Only vehicles delivering LPG should be allowed within 1m of the storage area. No opening into buildings, cellars or pits should be within 2m of an LPG storage area. No flammable liquids, combustible, corrosive or oxidising material should be stored within 3m of an LPG store. Compressed oxygen must be kept 10m away from all flammable gases; these include propane, butane and dissolved acetylene. The area should be kept clear of weeds and rubbish. The storage of LPG should not hinder or endanger the means of escape from the premises. The extent of the storage area should be clearly marked and suitable notices displayed prominently (available from *****). Appropriate steps should be taken to prevent tampering and vandalism. In many cases it may be appropriate to enclose the storage area in a lockable cage. The same restrictions apply to empty cylinders as to full ones. Storage above 400KG For larger storage, other safety requirements exist, including the maintenance of a minimum separation distance between bottle storage and any boundary, building or fixed source of ignition. This is determined by the total amount of LPG stored and the size of the largest stack of bottles - whichever gives the greatest distance. In certain circumstances this separation distance may be reduced by the use of a radiation wall. By complying with these separation distances and other safety requirements, ****** are able to store upwards of 200 tonnes of bottles at our filling terminals. For further information on cylinder storage please consult the LPGA Code of Practice no.7, available from the LP Gas Association one google search found this in seconds. other sites are out there http://www.lpga.co.uk/LPGA.htm - The Liquid Petroleum Gas Association (not the golfing one!) http://www.synergyassetservices.co.uk/index.html

Posted By DILIP My question was actually replied to some extend. let's look at the following link photo. http://www.med.cornell.e...s/1.3_compressed_gas.gif Does it correct? In my opinion it is not safe.Inadvertent falling of one cylinder will definately may result in to chain reaction and thereby another also fell and may result into the rocketing effect. Thus may result into the catastropic event. Hence, please explain me exact interpretation of the securing the cylinder mean? ofcourse not from the stealing but from the hazard/risk point of view. Thanks for active participation. What's the regulation says about it? Is there any guideline?

Posted By Pete48 To try and help Dilip a little more. I don't think that any UK standards or guidance actually give the information that he seeks, do they? The principle is only that the cylinders must be secure. Chains, of adequate size, properly fastened and correctly positioned on the cylinders, are an acceptable means to secure a group of cylinders when stored in low risk situations. It is only once cylinders are in use, when the risk from unsecured cylinders is clearly much greater, that best practice demands either individual restraint or suitably designed cages/trolleys for multiple cylinders. Anyone out there with any more detail or comment?

Posted By Tabs Dilip, A falling cylinder is bad. Several falling cylinders is much worse. If you use one chain, and the cylinders become unstable (maybe knocked on one side) it might be that as the chain is released many cylinders all fall at once. I would not like to be the person near those cylinders - even if they do not damage the fittings, they are very heavy and very mobile (rolling) and a person will be in danger if they are in the path of the cylinders. Do not rely on regulations to provide a safe environment, use your experience and intelligence. I cannot think of any such legislation. If you cannot secure each cylinder individually, at least reduce the number to a few held by one chain...
