In response to a request from the Montana Department of Health, an investigation was made of possible hazardous working conditions at the Louisiana-Pacific Corporation (SIC-2492), Missoula, Montana. Upper respiratory irritation, headaches, and dizziness had been reported by workers in the particle board painting department. Eight workers operated the automated painting process. Full shift time weighted average exposures to solvent mixtures ranged from 26 to 110 percent of the combined evaluation criteria for individual solvents. Toluene (108883), methyl-ethyl-ketone (78933), and methyl- isobutyl-ketone (108101) were the major solvent components. Air formaldehdye (50000) concentrations ranged from 0.1 to 0.3mg/m3. The printer operator was exposed to 50mg/m3 of butyl-cellosolve (111762). The author concludes that a potential hazard from overexposure to organic solvent mixtures existed as well as overexposure to formaldehyde. The author recommends that the ventilation system in the painting department be checked and upgraded to ensure that it is able to provide the recommended capture velocity at the paint rollers, that additional ventilation methods be installed where needed, that butyl-cellosolve be replaced, and that a medical surveillance program be established.
