Most of us have a LPG tank on site and many of us have multiple tanks lined up next to each other. As part of their “Coffee Break” training the United States Fire Administration (USFA) has just released a GREAT resource for our engineering groups to aid them when locating these LPG tanks. Now this is NOT a facility siting aid, but rather an aid to show us how far apart these tanks need to be located from one another. Liquefied petroleum gases (LPGs) include propane, butane, and other LPG mixtures that are popular fuel sources for heating, cooking, illumination, and industrial processes. LPG has an ignition temperature in air of 900ºF to 1,020ºF (482ºC to 549ºC) and a maximum flame temperature in air from 3,595ºF to 3,615ºF (1,979ºC to 1,991ºC). These hazards require that storage facilities be arranged to minimize catastrophic events. National Fire Protection Association (NFPA)® 58, Liquefied Petroleum Gas Code, includes distance requirements for separating LPG containers from adjacent containers, important buildings, groups of buildings, or the property line of adjacent parcels where structures can be erected. By the way, most State Fire Codes and Building codes use NFPA 58 as their basis. Click Here to get this one-page fact sheet.
