The Li Ka Shing Knowledge Institute uses environmentally friendly sharps containers across the facility. A sharp is any object with corners, edges, or projections capable of piercing the skin. Sharps include both contaminated (biohazardous and chemical) and uncontaminated sharp objects.

Take extra precautions while using sharps, during the cleanup and during disposal. If possible, avoid the use of sharps!
