Abstract
In response to a request from the United Mine Workers of America, Deputy Administrator of Occupational Health, a study was made of worker exposure to a resin used in the roof bolting operation at the Freeman United Coal Company Mine No. 6 (SIC-1111), located in Frankfort, Illinois. One worker developed a severe asthma attack following initial exposure to the resin, Du-Pont FASLOC, and was diagnosed by two pulmonary medicine specialists as having occupationally induced asthma. Sensitization to the resin or its components was not tested. Three other workers reported headaches, sore throats, and coughs following exposure. All four were interviewed, and medical histories were requested but only one was obtained. Air samples were taken near machine operators' breathing zones and downwind of vapors during roof bolting. These were analyzed for resin components, styrene (100425), vinyl-toluene (25013154), or butyl-benzyl-phthalate (85687). There were no detectable levels of the latter two chemicals, and styrene was present near the detection limit of 0.05 part per million. The authors conclude that there is no health risk to the general work force from this resin. However, if a true hypersensitivity does exist in the asthmatic individual, further resin exposure would be harmful to this worker.
