Kerosene should only be stored in a clean, new and sealed container that is clearly marked for kerosene. Proper containers for kerosene can be made of plastic or metal, but because non-approved plastic containers may degrade the kerosene in as little as two weeks, a metal container is a safe alternative. Many manufacturers suggest using a blue container to store kerosene so as to differentiate it from red gasoline containers.
The use of storage containers such as used fuel drums, milk containers, used plastic jugs and used gasoline cans may cause fires, kerosene contamination or harm to the kerosene wick. Even if kerosene is stored in a proper container, keeping the container in direct sunlight or high heat, as well as storing the kerosene for a long period, can cause contamination. If kerosene has been stored improperly, contamination is easy to spot: the kerosene likely has a yellow or cloudy color, visible debris floating inside it and water floating on the bottom of the container.
Through the second half of the 20th century, one of the most popular kerosene storage manufacturers was Blitz USA. The company's products still dominate the market, but Blitz ceased its operations in 2012 amid controversy and steep personal injury lawsuit costs.
