HAV, or Hand-Arm Vibration, refers to the vibrations transmitted from tools or machinery to a worker's hands and arms. Prolonged exposure to HAV can lead to health issues, including Hand-Arm Vibration Syndrome (HAVS), which affects blood vessels, nerves, and joints. To minimize risks, employers are encouraged to implement control measures, such as using low-vibration tools and providing regular breaks. Workers should also be trained to recognize symptoms and report any discomfort early to prevent long-term damage. Awareness and proper management are essential for maintaining safety in environments where HAV is a concern.
