Development of a Hand Tool Work Analysis Method (HTWAM)

The HTWAM method and software for the analysis of activities involving the use of hand-operated non-powered tools has been developed and tested in practice as part of the Eurohandtool project. The method was used to investigate 12 jobs in viticulture and 5 jobs in other sectors where hand tools are used. HTWAM showed itself capable of identifying weak points in a work system. HTWAM enables design engineers to perform work system analyses which can provide industry with recommendations for the ergonomic design of hand tools and can also give users information on the need for safety precautions and avoidance of health risks.
