Explanation:

It is very dangerous to throw away broken glassware which has been in touch with chemical products in regular garbage or recycling containers. The problem is it can lead to serious injuries if a worker collects it and is not aware of its presence in the garbage bin. The correct way to dispose of broken glassware is to wrap it up in many layers of paper or put it in a box, adding a note when possible indicating that there is broken glass inside.
