(d)
Hand arm vibration is a physical hazard which transmitted to the worker's hand during
operating handheld machine. The worker exposed to hand arm vibration at x-axis = 5
m/s², y-axis = 3 m/s² and z-axis = 2 m/s² for 1 hour operating the power tool machine.
Mathematical formula for vibration total value is anv = √√ahwx + anwy + awz and
daily vibration exposure is A(8)= ahv To
i.

Plan the management process flow on how to control the risk. Illustrate two
(2) examples of control measures
Determine the total daily vibration exposure, A(8) value and compare whether
the vibration exceed the exposure action value (EAV) of 2.5 m/s².
