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's hospital facility. Workers inside the plant who'd been exposed to the toxic substance trinitrotoluene, were immediately treated in this on-site medical center. Poisoning took place when the TNT became airborne through its volatility, or through the inhalation of contaminated dust particulates, as well as when the substance came into accidental contact with the 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.
