Description:This 1948 historical photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). The image depicted a safety engineer who was in the process of conducting a dust count on his grid-screen. Respirable dust is a concern in many industries, both as a repiratory irritant, and as a process contaminant, especially in the case of microcircuitry production.
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.
