This 1947 historical photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), and depicted two men, who were operating a hay shredder, stacking the hay on a wagon alongside the shredder. This process was taking place on a Kansas farm.
This image was part of a collection that was used to document the many aspects of various industrial activities, and their associated hazards, enabling NIOSH to create a safer workplace through substantiation of appropriate safety regulations. 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.
