Oily rags should be stored in a metal can because this type of container is designed to be fire-resistant, which is crucial for safety in a workshop environment. Oily rags can spontaneously combust if left in a pile or stored improperly, as the heat generated by oxidizing oils can ignite the material. A metal can also protects the rags from external elements and reduces the risk of fire spreading.

Unlike plastic bags, which can melt and retain heat, or wooden boxes that are combustible materials themselves, metal containers are equipped with a secure, often self-closing lid that limits oxygen access, further decreasing fire hazard risks. A paper towel holder is not suitable, as it doesn’t provide the necessary containment or protection against fire. Storing oily rags properly not only maintains safety in the workshop but also adheres to best practices for handling flammable materials.
