[1] Workers there were potentially exposed to the industrial solvent trichloroethylene (TCE), classified by the International Agency for Research on Cancer (IARC) as a probable human carcinogen.
This assessment discovered volatile organic compounds well above the levels specified by the United States Environmental Protection Agency (U.S. EPA).
The various concerns who owned the View-Master franchise in the 1950s through the 1970s (Sawyer's and GAF), acknowledged using TCE to clean and de-grease parts and equipment, and disposed of the chemical on-site.
[1] The U.S. EPA is in the process of evaluating the carcinogenic and non-carcinogenic human health risks from exposure to TCE.
[5] According to a study performed by the ODHS, among former factory workers, the number of deaths from several types of cancer was elevated.
[6] The ODHS has recommended that the health of the workers at the former factory be evaluated to determine the extent to which this population may have been affected by potential exposure to TCE.
