Area and personal air samples were analyzed for styrene (100425), acetone (67641), toluene (108883), xylene (1330207), cellosolve (110805), cellosolve-acetate (111159), and wood dust at Hinckley and Company (SIC-3732), Southwest Harbor, Maine in May, 1983. The survey was requested to evaluate possible health hazards from exposure to materials used in constructing fiberglass reinforced plastic boats. Noise level measurements were also made. The measured concentrations of styrene, acetone, toluene, xylene, cellosolve, and cellosolve-acetate were 18 to 258, 6 to 147, 590 to 692, 192 to 200, 1.2 to 5.7, and 1.9 to 14.2 milligrams per cubic meter (mg/m3), respectively. These concentrations were below their respective OSHA standards. Three styrene and the cellosolve and cellosolve-acetate samples exceed the NIOSH criteria. Wood dust concentrations were 0.7 to 16.2mg/m3. The OSHA standard for wood dusts is 15mg/m3. Noise exposures ranged from 76.1 to 89.1 A- weighted decibels (dBA). The OSHA noise standard is 90dBA. The authors conclude that there is a health hazard due to overexposure from wood dusts, styrene, and combined solvents, styrene plus acetone and toluene plus xylene. There is a potential hazard due to cellosolve, cellosolve-acetate, and noise exposure. Recommendations include installing local exhaust ventilation and using respiratory and hearing protective equipment.
