Very light oils – these include: Jet Fuel, Gasoline, Kerosene, Petroleum Ether, Petroleum Spirit, and Petroleum Naphtha. They tend to be very volatile, evaporating within a few days which in turn evaporates their toxicity levels.
Light oils – These include Grade 1 and Grade 2 Fuel Oils, Diesel Fuel Oils as well as Most Domestic Fuel Oils. They are both moderately volatile and toxic.
