Oily rags should be stored in a self-closing ________.

Oily rags should be stored in a self-closing ________.

• A. Metal container
• B. Plastic bucket
• C. Cardboard box
• D. Glass jar

Answer: (A)

Oily rags can heat up as the oils oxidize, and in a pile the heat has nowhere to escape, which can lead to spontaneous ignition. Storing them in a metal container with a self-closing lid is the safest option because metal resists heat better than plastic or cardboard, and the self-closing lid reduces the amount of air that can reach the rags. This containment helps prevent a fire from starting or spreading. Plastic buckets can trap heat or deform, cardboard is highly flammable, and glass jars, while sealable, are heavy and can break. Using a metal, self-closing container minimizes fire risk and makes disposal safer.
