Abstract

Debarking machines, used extensively in sawmills, require frequent unclogging and maintenance; these operations are hazardous. Data was collected during visits to sawmills and from international databases and was complemented by information, obtained from Québec manufacturers, on the latest developments in the field. This was followed by systematic risk analysis and prioritisation of hazards, and the formulation of recommendations concerning measures to improve the safety of debarker operation, maintenance, and unclogging. Both the results of this exercise and the literature cited in the report indicate the importance of according the highest priority to lock-out procedures. Design criteria for safety enclosures and protective booths are also described. The report cites two European technical guides which complement and support its conclusions. The researchers also verified whether recent models of debarkers produced in Québec incorporate safety-oriented features.
