scope:

These guidelines outline feasible ways in which possible hand-arm vibration hazard associated with hand-held, hand-guided and other machinery, may be reduced by machinery design in order to provide practical professional aid to designers and manufactures of machinery. The document covers four principal aspects of the reduction of the effects arising from exposure to hazardous machinery vibration: - reduction of vibration magnitude at source; - reduction of vibration transmission from the source to handless and other surfaces in contact with the hands; reduction of vibration transmission from the grips or handles of the machine to the hand-arm system of the operator by ergonomic design measures; - thermal design to optimise hand temperature.
