Influence of saw chain type and wood species on the concentration of wood dust in a forestry operation.

This study examines the impact of chainsaw chain type and tree species on the concentration of inhalable wood dust generated during motor-manual harvesting in forested areas. The effects of conducting real-world measurements of inhalable dust within the operator's breathing zone during forestry work are investigated. Two different chain types were evaluated: the commonly used 3/8" pitch chain (conventional chain) and the 0.
