Hand-arm Vibration (HAV) Assessment evaluates the potential health risks associated with exposure to vibrations transmitted to the hands and arms during work activities. This process involves measuring and analyzing vibrations generated by hand-held tools or machinery used by workers. The assessment aims to identify potential health effects such as hand-arm
vibration syndrome (HAVS), assess the magnitude and duration of exposure to vibration, and characterize the overall risk to worker health.

Conducting a Hand-arm Vibration Assessment is crucial for preventing occupational illnesses such as HAVS by identifying and mitigating risks early. It provides the basis for developing control measures, including tool selection, maintenance practices, work scheduling, and ergonomic improvements, to minimize vibration exposure. Additionally, this assessment guides decision making regarding the use of vibration-dampening technologies and personal protective equipment (PPE) to protect workers from excessive vibration. It also plays a vital role in educating workers about the risks of hand arm vibration and promoting practices that support safe working conditions and long-term health in the workplace.
