Small plants and their medical problems - the furniture industry: industrial hygiene aspects of the furniture manufacturing industry.
Occupational safety and health symposia 1979. Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. 80-139, 1980 Jun; :65-67
Health hazards in the furniture manufacturing industry were discussed. The main concerns were noise, solvent vapor, formaldehyde (50000), and wood dust. Local exhaust ventilation may be the only feasible way to reduce employee exposure to formaldehyde. Noise reduction can be achieved with enclosures on the planers, molders, and tenoners. Changes in the geometry of the saw blade and lining the saw guards with acoustic foam could effectively lower the noise. Dust was controlled by collection systems. Finishing materials contain a variety of volatile solvents. Methyl-n-butyl-ketone (591786) and benzene (71432) were no longer used. Since the effects of solvents are additive, the concentration of each solvent must be known to estimate an overexposure. Chemical resistant gloves, aprons, and clothing have been used as protection against dermatitis. Barrier creams also may be helpful. Upholsterers were exposed to low levels of cotton dust and suffered from occasional cases of dermatitis attributable to the fabric fire retardant. Employees who made plastic parts, generally made of polystyrene and rigid polyurethane, were exposed to diphenylmethane-diisocyanate (101688) (MDI), styrene (100425), diatomaceous-earth (68855549), silica (7631869), and methylethylketone-peroxide (1338234). Usually prepolymerized MDI was used which has a lower vapor pressure and is less likely to become airborne.
