Provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), this historic 1943 image depicted the exterior of an Ohio TNT military ordnance manufacturing plant. Workers inside were exposed to the toxic substance trinitrotoluene when it became airborne through its volatility, or through the inhalation of contaminated dust particulates, as well as when the substance came into accidental contact with their skin. A poisonous chemical, TNT will irritate the skin upon contact, and actually will change the skin's color to a bright yellow-orange. Prolonged exposure leads to liver damage, anemia, enlargement of the spleen, and a compromised immune system, to name a few of its negative effects. Trinitrotoluene is also a known carcinogen.
