• Chemical Hazards – carcinogenic, flammable, or corrosive materials

• Physical Hazards – pyrophoric materials, lasers or radiation

While in a laboratory at the NIH for any reason, all personnel must wear appropriate clothing attire that prevents direct contact of materials with the skin. Examples of attire that is appropriate include long pants or leg coverings and closed toe shoes. In addition, a task appropriate laboratory coat, as determined by a risk assessment, must be worn while performing laboratory operations.
