Description:In response to a request from the United Brotherhood of Carpenters and Joiners of America an investigation was made of health problems at the MonArk Boat Company, (SIC-3732), Monticello, Arkansas. MonArk manufactured aluminum and fiberglass boats. About 200 hourly production workers were employed at the site. Fiberglass reinforced plastic resin hulls were sprayed with a gel coat consisting of vinyl ester or polyester resins containing free styrene (100425) monomer and methyl-ethyl-ketone-peroxide (1338234) catalyst. Average exposures during the work shift to styrene vapor did not exceed recommended limits, but there were short term exposures of 114 to 250 parts per million (ppm). Exposures to 13 micrograms/cubic meter (microg/m3) of chromates and 160ppm of toluene (108883) exceeded recommended limits in the spray-painting area of the aluminum fishing boat facility. Exposures to methylene-bisphenyl-isocyanate (101688) (MDI) at 0.21 to 0.57mg/m3 exceeded the OSHA limit of at 0.7 to 3.1mg/m3. An organotin concentration of 0.38mg/m3 was found during a 49-minute period. The author concludes that health hazards exist from exposures to styrene, chromates, toluene, isocyanates, and possibly organotin. The author recommends that efforts be made to improve use of personal protective equipment, educate the employees to the dangers, improve ventilation practices, and institute a medical surveillance program.
