This historical 1943 image, which was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), depicted two inhouse nurses examining fellow coworkers at an Ohio TNT (trinitrotoluene) military ordnance manufacturing facility, for symptoms of TNT poisoning. The nurse the right was in the process of taking a blood pressure reading from one female employee using a sphygmomanometer, while the nurse at left was performing a finger stick (See PHIL 9790), thereby, extracting a blood sample that would later be analyzed for the presence of metabolites indicative of TNT poisoning.
