In response to a company request, an investigation was begun into worker exposure to formaldehyde (50000) at Medite of New Mexico (SIC- 2493), Las Vegas, New Mexico. The facility employed about 135 hourly employees in the production of fiberboard. Occupational exposures to formaldehyde, formaldehyde on dust, and total wood dust and inhalable wood dust were measured before and after process and engineering control changes were implemented by the company. The range for three personal breathing zone exposures for formaldehyde was 0.029 to 0.48mg/m3. Wood dust exposures ranged from none detected to 21.03mg/m3. The results indicated that formaldehyde and wood dust exposures at this fiberboard manufacturing facility were a health hazard. The company made a number of changes designed to reduce formaldehyde exposures during the study period, which were effective in significantly reducing, but not eliminating, hazardous formaldehyde exposures. Wood dust exposures were not significantly reduced overall by the changes. The author concludes that formaldehyde and wood dust exposures were a health hazard at this facility. The author recommends that specific measures be instituted to control formaldehyde and wood dust exposures through the use of engineering controls and respiratory protection.
