These guidelines outline feasible ways in which possible hand-arm vibration hazards 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 manufacturers 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 handles 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 optimize hand temperature.
NOTE. These guidelines are not intended to be universal or detailed solutions but only technical methods which may be used to solve problems.
