• gases, delivered at low pressure or in the form of liquefied petroleum gases (LPG) such as butane, propane and acetylene, which are volatile, flammable, explosive and highly toxic;

• light gasolines used in the aviation, automotive and chemical industries, low-viscosity, flammable, volatile liquids;

• heating oil (FOD), heavy fuel oil (FOL), fuel oil no. 1, fuel oil no. 2, for heating purposes, highly viscous, flammable liquids.
