ABSTRACT
Worldwide there are millions of people who go to work each day who are exposed to mechanically induced vibration. These include truck, bus, heavy equipment, fork lift, farm vehicle operators, train engineers and conductors, miners, helicopter and fixed-wing aircraft, ship personnel and fixed plant sites. These people are exposed to head-to-toe whole-body vibration (WBV). Users of hand-held power tools such as chain saws, various electrical and air-driven pneumatic tools such as chippers, grinders, sanders, mining tools, drills, road rippers, etc. are exposed to segmental or hand-arm, vibration (HAV).
