In these particular places, the object of the activity is the most important danger: as a matter of fact, fuel vapours originated during the filling phase are easily (also with a spark) and highly flammable.
LPG (C3H8): used as a fuel, LPG is a mix of propane and butane, often containing ethanthyol to make it more easily detectable in case of gas leak.
C3H8: when loading and unloading the product from tank trucks into storage tanks or vice versa, there mat be fuel spillage which is very dangerous due to high flammability of this product even by a minimum spark. Other causes of spillage may be due to leaks from the plant. LPG is more dangerous than other inflammable gases due to its poor volatility, in fact, it forms pockets stagnating on the floor.
