Health-hazard evaluation report HETA 87-309-1906, Louisiana-Pacific Corporation, Missoula, Montana

Technical Report ·
OSTI ID:6519510

An investigation was made of possible hazardous working conditions at the Louisiana-Pacific Corporation, 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% of the combined evaluation criteria for individual solvents. Toluene, methyl ethyl ketone, and methyl isobutyl ketone were the major solvent components. Air formaldehyde concentrations ranged from 0.1 to 0.3mg/mT. The printer operator was exposed to 50mg/mT of butyl cellosolve. 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.
