The right answer is broken glass container.
Broken glass is a common type of waste in the laboratory.
Improper disposal of glassware may result in injury to persons handling laboratory waste. Any laboratory glassware, including empty containers, pipettes, slides, plates, tubes, flasks and cups must be properly handled for disposal.
The broken laboratory glassware must be placed in boxes designed for this purpose. These boxes, identified as broken glass boxes, should be available in laboratories.
