On these premises, the main activity is the first cause of hazard. In fact, if fuels spill out of their containers, they and their vapours represent a top-grade danger of flammability so that they can be triggered off even by the smallest energy sources (spark).
Petrol vapours (C6H14 – C8H18): petrol is generally a mixture of paraffinic hydrocarbons between hexane and octane in changeable proportion.
Diesel oil: Diesel oil contains different classes of hydrocarbons such as paraffin, aromatics and naphtheneses, and their proportion changes according to the type of Diesel oil. Paraffinic hydrocarbons have the best ignition and combustion qualities, since they are more stable.
Kereosene : intermediate hydrocarbon fraction ranging between petrol and Diesel oil, got by distillation of crude oil at 150°C to 250°C.
C6H14 – C8H18: Gasoline is extremely flammable, even by a simple spark.
Kereosene : its ignition is very difficult because it requires high temperature and high pressure. However, it needs to be monitored for handled quantities and potential combustion in case of fire.
