Description:Dr. Frederick H. Goldman in the Industrial Hygiene Laboratory, National Institute of Health (NIH), Washington, DC. The purpose of the laboratory would have been to analyze samples from industrial hygiene investigations and to develop analysis methods. Goldman and Morris B. Jacobs authored Chemical Methods in Industrial Hygiene, 1953. Original caption of related photograph: “In the Industrial Hygiene Division, National Institute of Health, a doctor accomplishes extraction of biological material by means of organic solvents.”
No information is available on industrial experience with this substance, and no epidemiological studies have been conducted in xylidine-exposed workers. However, it is believed that a 1-hour exposure to a 400-ppm concentration of xylidine or that long-term exposure to a 10-ppm concentration of this substance would be lethal to humans [ACGIH 1988b, p. 640.1(88)]. Based on effects seen in animals, it is likely that xylidine can be absorbed through the skin in sufficient amounts to cause dangerous methemoglobinemia [Gosselin, Smith, and Hodge 1984, p. II-208].

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.
