6.2: Broken Glass and Sharp Objects

  • These two types of waste require separate containers. Receptacles for broken glass are placed at strategic points in the organic labs (see picture below). Unfortunately, some students confuse these containers with trash cans. BROKEN GLASS RECEPTACLES ARE NOT TRASH CANS. Please do not place anything in these boxes other than glass. The only exceptions to this rule are Pasteur pipettes that may contain silica gel, alumina, or cotton inside. You can place these pipettes into the broken glass box without having to empty them first. However, the rubber bulbs that are commonly used with such pipettes are not disposable. Please do not dump them into the trash can or the broken glass boxes.

    A BROKEN GLASS RECEPTACLE IS NOT A TRASH CAN

    Sharp objects also require a special container. This container is typically a red plastic box located in the waste hood. The container is designed so that objects can go in easily, but cannot be taken out. Examples of sharp objects commonly used in the organic lab are disposable syringe needles. Please place such items in the sharp objects box.
