Posted By Peter Rees Ian Although I haven't the info that you are after, don't forget that your petrol may also be subject to the DSEAR regs depending upon how you use it, store it etc

Posted By Paul Huber Ian, Depending on the quantities stored you may need to contact the Petroleum Licensing Authority (Trading Standards or Fire Brigade). If so the license conditions will form a basis for your risk assessment. If a license is not required then you need to treat it as a highly flammable liquid and do the assessment that way. Storage of small quantities is relatively simple to assess (you may need a petroleum storage cabinet [mega expensive!]). The real skill comes in assessing the risks associated with use. If it is kept in small quantities for use in vehicles or machines such as mowers then you do not need a license and the principal control would be to carry out re-fuelling in the open air, away from naked flames, etc. Use indoors may require some more sophisticated control measures Check out the HSE web site (free leaflets - Motor vehicle Industry) they have general advice.
