The minimum safety separation distance between liquefied petroleum gas (LPG) storage tanks and buildings varies depending on factors such as the type of building and the size of the tank.
Generally, for important public buildings, the minimum safety distance from an LPG tank with a capacity of 10 cubic meters or less is typically around 50 meters; for tanks with capacities between 10 and 50 cubic meters, this distance increases to approximately 60 meters; and for tanks exceeding 50 cubic meters, the distance requirements are even stricter. Regulations also exist for civil buildings regarding their proximity to LPG tanks of various sizes. For instance, the minimum safety distance from a tank with a capacity of 10 cubic meters or less is roughly 25 meters, while the distance required for larger tanks is greater. These regulations aim to minimize potential harm to buildings and people-and ensure safety-in the event of an accident, such as a leak.
Regarding important public buildings, safety distances are established to protect locations where large numbers of people congregate. A distance of approximately 50 meters for tanks of 10 cubic meters or less provides sufficient space to buffer against hazards in the event of an accident, preventing catastrophic damage to the building. As tank capacity increases, so does the level of risk; consequently, the safety distance is extended to 60 meters or more to ensure effective risk mitigation under various conditions.
Safety distances between civil buildings and LPG tanks are determined by considering both daily resident activities and safety requirements. A distance of around 25 meters for tanks with capacities of 10 cubic meters or less offers a degree of protection for residential properties. As tank capacity increases, the potential risks of fire and explosion rise, necessitating greater separation distances to safeguard residents' lives and property, and to minimize the potential impact and scope of any accident.
