The Occupational Safety and Health Act of 1970 authorizes the National Institute for Occupational Safety and Health (NIOSH), on appropriate request to investigate conditions where a potential health hazard is suspected.
JOM is reviewing, as case studies and as teaching tools, reports of such NIOSH Health Hazard Evaluations investigations. This month Case Reports No. 7 and No. 8 represent edited versions of selected reports which we believe are of interest to industrial physicians and industrial hygienists.
The comments of readers concerning the problems discussed in these reports will be welcomed and will be published as space permits.
