HHE Report No. HETA-91-298-2182, Gibson Flatiron, Erica Shell Manufacturing, Bozeman, Montana.
NIOSH 1992 Feb:12 pages
In response to a request from the Montana State Health Department, an evaluation was undertaken of exposures to wood dust and lacquer vapors at the Gibson Flatiron/Erica Shell Manufacturing Companies (SIC-3931), Bozeman, Montana. Gibson Flatiron manufactured mandolins and banjos. Erica Shell Manufacturing Company cuts and grinds abalone and other sea shells into small pieces to be used in designs inlayed into mandolins and banjos. Measured wood dust levels ranged from 0.8 to 32mg/m3 with an 8 hour time weighted average (TWA) of 1.2 to 30mg/m3. Rib construction and assembly, and planing bulk ebony wood had TWA exposures above the OSHA permissible exposure limit of 5mg/m3 for wood dust. Application of dyes and finishes resulted in low exposures to acetone (67641), toluene (108883), xylene (1330207), and butyl-acetate (123864). No solvent air concentrations were above 10% of their respective PELs. The author concludes that a health hazard existed for exposure to wood dusts. The author recommends the establishment of a respiratory protection program and a hearing conservation program. Emergency egress routes should be marked in the buildings.
