Health hazard evlauation report: HETA-81-292-996, Log Homeowner, Brodhead, Kentucky.

Possible overexposure to toluene (108883) by an occupant of a recently constructed log home was investigated in Brodhead, Kentucky, on April 20, 1981. The resident of the home requested the evaluation after developing headache, disorientation, a severe nosebleed, and abnormal liver enzymes elevation, subsequent to having his home caulked. Air samples taken six weeks after the caulking revealed toluene air concentrations of 2 parts per million (ppm) compared with the OSHA standard of 200ppm. Laboratory analysis of the caulking compound showed it to be approximately six percent toluene, 0.5 percent xylene (1330207), and 15.5 percent naphtha (8030306) on a weight to weight basis. The author concludes that the history of the affected individual's illness, and the additional symptoms in other family members, suggest an association with exposure to volatile solvents contained in the caulk. She recommends safety labelling for any caulking compound designed for use inside homes, use of such caulking compound only with adequate ventilation, and proper training of professional caulking installers.
