Recycling of rags and brushes containing paint, solvent or linseed oil
Rags or brushes stained with paint, solvents or linseed oil are also hazardous waste, as the hazardous characteristics of the substance do not disappear as the product dries. Sort the rags and brushes according to the following instructions:
Rags and brushes containing paint or solvent
- Collected in a metal bin at the work area, from where they are delivered to the Kaikukatu 5 waste room.
- When the metal bin is full, the rags or brushes are delivered to the Kaikukatu 5 waste room in a waste bag. The bag should be marked “solid paint waste” and sorted into the solid paint waste container.
Linseed oil rags and brushes
- Linseed oil rags are highly flammable!
- Used rags and brushes should be laid out to dry, opened, on a non-combustible surface. Rags should not be left in a pile, as this increases the risk of flammability.
- Dried rags and brushes should be placed in a metal trash can with a lid in a cool place. A plastic bag will not be placed in the metal trash bin.
- Disposal as hazardous waste. When the container is full, it will be delivered to the Kaikukatu 5 waste room and the need to empty the container must be reported.
