Health Hazard Evaluation Report No. HETA-81-270-1012, Lear Siegler, Inc., San Diego, California

摘要

On April 6, 1981, the National Institute for Occupational Safety and Health (NIOSH) received a union request to investigate an apparent increased incidence of miscarriages among workers at Accurate Products Division (AP) of Lear Siegler, Inc., San Diego, CA. The health hazard evaluation was conducted on June 11 and June 18, 1981, by doctors from the University of Southern California School of Medicine under contract with NIOSH. A review of previous evaluations of the plant by the California Occupational Safety and Health Administration (Cal-OSHA) inspection and follow-up suggested there might be a problem with reproductive capacity as a result of worker exposure to ethylene thiourea. This evaluation did not find any adverse reproductive effects which could be attributed to the work environment, although the small numbers available for study prevent the possibility from being entirely ruled out. Further, because of the small number of workers and the limited availability of records this does not appear to be a good setting to be included in an industry-wide study of the problem.
