How to Safely Dispose of Solvent and Oil-Soaked Rags
Flammable and combustible liquids such as gasoline, acetone and mineral spirits are dangerous chemicals to handle, including solvent-soaked items with which you are working. In fact, rags and cloths soaked in these types of chemicals can go up in flames quite easily if they come in contact with an ignition source. To reduce the risk of fire:
Dispose of flammable and combustible liquid wipes and refuse in closed metal containers.
Make sure that the container is labeled properly and that it is legible for all workers.
Empty all trash containers daily.
