|Description:||This 1946 historical photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). The photo showed workers whose job it was to formulate spray-pesticides. They were mixing the powdered constituents into a liquid. The mixing was occurring in closed chambers equipped with exhaust ventilation systems. In addition to the ventilation, the workers were also wearing respirators and rubber gloves, in order to help prevent overexposure and poisoning. The pesticide pictured was Genithion P-15, an insecticide that is a variant of parathion. Activities such as this need stringent oversight by a regulating body such as NIOSH, which would make the health and welfare of such workers a paramount concern.|
The NIOSH Historic Photo Collection began as the “picture file” of the Industrial Hygiene Division of the U.S. Public Health Service (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.
