Personal and ambient full shift concentrations of inhalable wood dust were measured at different wood-working processes in two joineries and a furniture factory in The Netherlands.
The current occupational exposure limit for wood dust is still 5 mg m-3 total dust, but the Dutch Expert Committee for Occupational Standards has recently recommended a health-based limit of 0.2 mg m-3 (total wood dust).
The main purpose of the present study was to characterize current wood-dust exposures during different wood-working activities in order to determine whether compliance with the proposed limit was feasible.
The wood-dust exposures in the joineries were usually much lower than 5 mg m-3, but in the furniture factory the present limit was regularly exceeded.
Sanding, especially hand sanding, nearly always resulted in exposures above 5 mg m-3.
Almost all personal exposures were higher than the proposed health-based limit of 0.2 mg m-3 and therefore can be considered to generate a health risk to the workers.
The measurements performed may help in setting priorities and will serve as a basis for the development of a control strategy to reduce the average exposure.
