Fuel canister
A wide variety of container types and constructions are used for fuels. Each has its engineering challenges. The jerrycan is a robust liquid container initially made from pressed steel. It was designed in Germany in the 1930s for military use to hold 20 liters (4.4 imp gal; 5.3 US gal) of fuel. Three handles allow for two people carrying a whole can or one person handling an empty can. The basic design is still in use today, although construction is often of high-density polyethylene. Portable plastic gasoline containers are commercially available and are in everyday use. These are usually blow-molded polyethylene or other polymers compatible with the designated fuel. It has been found that using flame arresters reduces the chance of fire or gasoline explosion. Child-resistant caps or closures are required in some regions or jurisdictions.]A drum (also called a barrel) is a cylindrical container used for shipping fuels. A typical drum has a nominal capacity of 200 liters (55 US or 44 imp gal). Drums are usually made of steel, but plastic drums are used for some liquids. Fuel drums need to have the appropriate certification for shipment of dangerous goods: Flammable liquids, etc. Steel drums are suited for reconditioning for multiple uses.
