|Description:||This historical drawing, provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), detailed a design for a foundry ventilating system, in which dust is a significant by-product of the foundry’s activities. In the 1940s and 1950s, the Industrial Hygiene Division (IHD) investigated hazards associated with this and other activities involving workplace health hazards.|
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.
