|Description:||This 1947 historical photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). The image showed two men who were operating agricultural processing machinery, which appeared to be a hay shredder. The hay that had been stcked on a hay wagon, had been pulled up alongside the shredder, which after chopping the hay into small pieces, conveyed the grass up a shoot, which was then dumped into a large holding containment vessel at the far left. At the time, 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, so as to better understand these workplace environments, and their associated hazards. In gaining a better understanding of workplace hazards, protocol-formulating bodies such as NIOSH, are better able to create a safer workplace through substantiation of appropriate safety regulations.|
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.
