Communicating a Hazard in the Workplace

An Exposure Control Plan explains how an employer has decided to make an employee aware of potentially infectious materials. Biohazard signs and labels indicate hazardous materials, potentially contagious, or anything contaminated with blood or body fluid.

A biohazard label or sign should be attached to each object or container of contaminated materials by string, wire, adhesive, or another method that prevents loss or unintentional removal of the label or sign.

Signs should have a fluorescent orange or orange-red background with a black “biohazard” symbol in the foreground. Labels must contain the biohazard symbol and must have the word “biohazard” written on them.

A sign or label is unnecessary when red bags or containers with the biohazard symbol are used. Properly indicating contaminated materials using labels and signs will greatly reduce the risk of accidental exposure. Be sure that you are aware of and abide by all signs and labels signaling hazards and hazardous materials.
