Nurses drawing blood and taking blood pressure of women ordnance workers in the hospital and dispensary of the Ravenna, Ohio Ordnance Plant. The Ravenna Ordnance Plant manufactured ordnance containing trinitrotoluene (TNT) for the military during World War II. The photograph was made during the industrial hygiene and engineering activities conducted by U.S. Public Health Service personnel at the plant in September 1943. Occupational safety and health concerns included preventing dermatitis among the workers and reducing the risk of explosions in the plant. The original caption of a related photograph states that TNT workers receive blood count and blood pressure checks every three weeks.
The NIOSH Historic Photo Collection from which this photograph was derived, began as the Picture File of the Industrial Hygiene Division of the USPHS, c. 1930-1960. It is a unique collection of mid-20th Century images of American workers and workplaces, and documents occupational safety and health research of that era. The collection consists of approximately 1,000 original photographs and schematic drawings.
