Risk Assessment and Management of Repetitive Movements and Exertions of Upper Limbs

Job Analysis, Ocra Risk Indicies, Prevention Strategies and Design Principles

In industrialised countries, musculo-skeletrical disorders of the upper limbs represent one of the commonest work-related diseases. All working activities habitually requiring repetitive upper limb movements and exertions represent a potential risk for these disorders under certain conditions.

This practical manual provides a clear and detailed solution to the problem of assessing and consequently managing these risks in conformity with European Union legislation covering the safety and protection of workers' health. The book contains many tables, diagrams and schedules, enhancing its practical value. The methods it proposes for analyzing and designing or redesigning jobs and tasks do not require sophisticated equipment and are largely based on situations encountered in large manufacturing factories.

Since risk analysis also concerns how jobs and tasks are organized, many concepts and terms are defined that prevention experts can share with those responsible for planning and organizing manufacturing activities on the shop floor.
