Signs, Labels & Color Coding

Biohazard warning labels need to be affixed to containers of regulated waste; refrigerators and freezers containing blood or other potentially infectious materials; and other containers used to store, transport, or ship blood or other potentially infectious materials.

These labels are fluorescent orange, red, or orange-red, and they are available from University Stores.  Bags used to dispose of regulated waste may be red or orange- red. Bags are then placed in the appropriate waste container that will be pre-labeled.
