Description:This 1958 historical photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), and depicted a worker in Lompoc, California, handling bags of diatomaceous earth while wearing protective clothing. The image originally appeared in a U.S. Public Health Service Publication No. 601, in an article entitled,“Pneumoconiosis in Diatomite Mining and Processing”, 1958. Inhaled dust or other airborne particulate materials containing silica that is deposited in the lungs, will cause the lung tissue to react by creating generalized nodular fibrotic changes, and is known as ”pneumoconiosis”, which is also know an pneumosilicosis, or ”grinders’ disease”.

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.
