Signs, Labels & Color Coding

Biohazard warning sign

Signs and labels in the workplace communicate bloodborne pathogen hazards to employees. The warning label must include the universal biohazard symbol and the term "biohazard" in a color that contrasts with the fluorescent orange, orange-red background, as illustrated to the right:

Warning labels must be affixed to containers of regulated waste, refrigerators and freezers containing blood or other potentially infectious material, and other containers used to store, transport, or ship blood or other potentially infectious materials. Red bags or red containers can be substituted for labels.

Contaminated equipment which is to be serviced or shipped must also have a warning label and a statement regarding which portions of the equipment remain contaminated.
