Rags soaked in gas, oil-based paint, oil, solvent and other flammable liquids
Be cautious when handling rags soaked in gasoline, oil or other flammable liquids. Place in a small, airtight, non-combustible (such as metal) container with a tight-fitting lid and seal tightly. Do not put in the garbage.
