Vibration - Measurement, Control and Standards - Canadian Centre for . . . Vibration exposure direction is also important and is measured in defined directions Vibration frequencies and duration of exposure are also determined How hard a person grips a tool affects the amount of vibrational energy entering the hands; therefore, hand-grip force is another important factor in the exposure assessment
Vibration - Introduction Vibration - Canadian Centre for Occupational . . . The risk of vibration-induced injury depends on the average daily exposure An evaluation of the risk takes into account the intensity and frequency of the vibration, the duration (years) of exposure and the part of the body which receives the vibration energy Hand-arm vibration causes damage to hands and fingers It appears as damage to blood

CCOHS: Noise - Control Measures Vibration of large structures (e g , ventilation ducts, guards on machines, equipment supporting structures, etc ) The sound may be amplified by reflective surfaces that are around the devices Aerodynamic sources of noise are air or fluid flows through pipes and fans or as the pressure drops in the air distribution system
Work-related Musculoskeletal Disorders (WMSDs) - Risk Factors Whole-body vibration is experienced by truck and bus drivers, for example Localized vibration exposure can be caused by power tools Common symptoms are numbness of the fingers, loss of touch and grip, and pain In addition, the worker may use more force and awkward body positions because vibration hand tools are harder to control
