Each individual has the responsibility for seeing that waste chemicals are safely collected, identified and stored for disposal, and that anyone involved is fully advised of the need for any special methods or facilities for proper disposal.
Handling of Waste
Chemicals are everywhere: they can be found in animals, plants and water as well as in many commercially available products including medicines, detergents, paints,and foods. The risk may be low, but present. In order to keep the risk to a minimum, all chemical waste must be disposed of properly. Once a material is declared a waste, the first responsibility for guiding its proper disposal rests with the worker. He or she is in the best position to know the degree of hazard posed by the material they have used and must provide sufficient information to fit it into the correct channel for disposal.
