|Description:||A Wheelabrator machine at Crown Cork and Seal Company, Baltimore, Maryland in April 1953. Original caption: “Wheelabrator – A machine to remove scale and rust from castings and forging. The ventilating ducts and storage hopper, where the steel shot is held, illustrates an enclosed process to protect the worker.” The sign on the machine next to the lower ductwork and can on floor reads, “Do not deposit trash in this can.” The photograph was probably made as part of a study by the U.S. Public Health Service, Industrial Hygiene Division.|
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.
