This historical 1943 image was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). Depicted, was one of two inhouse nurses examining fellow coworkers at an Ohio TNT (trinitrotoluene) military ordnance manufacturing facility, for symptoms of TNT poisoning (See PHIL 9788 and 9789). This nurse was in the process of performing a finger stick, in order to extracting a blood sample that would later be analyzed for the presence of metabolites indicative of TNT poisoning. 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.
