Type II Safety Cans
Gasoline and other flammable liquids are transported or stored in Type I and II safety cans. They help to eliminate vapor leaks and spills. Filling and pouring fluids is done through a single aperture on Type I safety cans. One aperture is for filling and the other is for pouring in Type II safety cans. While the other opening is used for pouring, the fill opening functions as a vent.
