There is no completely safe way to store fuels such as gasoline, diesel and gas. These are naturally flammable or explosive materials. Fuels stored even in so-called "safe containers" (or gallons) can be dangerous, especially if these containers are placed in closed or unventilated areas. The high temperature in the storage area also causes excessive pressure that leads to the expansion of these materials and the emission of dangerous fumes that greatly increase the risk of ignition and explosion. Evaporation of less than half a liter of fuel is enough to fill an entire home garage with explosive fumes. For your safety, commit not to store fuels, especially in residential buildings and in shops.
