This tool helps to assess the risk while working outdoor on forest sites, e.g. while felling trees and moving tree trunks. It is intended mostly for micro and small companies, but it can also be used by large forestry companies. The tool covers a broad variety of risks, including risks when operating a chainsaw and tractor, falls from height, risks related to overturning knocked down trees on slippery and uneven terrain, biological hazards due to forest work (ticks and other animals), harmful noise and vibration effects, unfavorable climatic conditions as well as ergonomic risks due to prolonged static body positions or manual handling of loads.
