This photograph, provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), depicted a male Public Health Service (PHS) officer as he was observing the workflow of two female 'shell pourers', inside a military TNT (trinitrotoluene) ordnance factory. 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. Neither the women, nor the officer were wearing any protective filtered breathing masks, however, the women were wearing gloves.
