Broken glass that is not contaminated with a biological, chemical or radiological agents should be placed in a rigid cardboard container designed for broken glass which incorporates a thick polypropylene liner to safely contain broken glass. These "broken glass" containers are available from common laboratory supply companies such as VWR and Fisher Scientific. Once full, seal the container with tape and leave for disposal with other normal trash. If the glass is contaminated with a biological agent, dispose of the glass in a sharps container. If the glass is contaminated with a chemical agent request a collection from EHS. If the glass is contaminated with a radiological agent, contact Medical Health Physics (MHP) at mhp@med.cornell.edu for disposal.
