Which condition is specifically described as a vibration-related disorder of the hands and arms?

• A. Hand-Arm Vibration Syndrome
• B. Raynaud's Disease
• C. Dehydration
• D. Back pain

Answer: (A)

Vibration exposure from powered hand tools can injure the hands and arms in a way that becomes a distinct syndrome. This condition—caused by repetitive vibration—affects the vascular, nervous, and musculoskeletal systems, leading to symptoms such as finger blanching in cold (a Raynaud-like presentation), numbness or tingling, reduced grip strength, and sometimes ongoing hand or finger pain. This is the best answer because it is the condition specifically defined by vibration exposure in the hands and arms. While Raynaud’s phenomenon describes similar finger color changes, it is a vascular condition not inherently tied to vibration exposure; HAVS includes that vascular aspect but is identified by its link to vibrating tools and the combination of vascular, sensory, and motor symptoms. Dehydration and back pain do not describe a vibration-related hand/arm disorder. Prevention focuses on reducing exposure time, using low-vibration tools, maintaining equipment, taking regular breaks, and implementing health surveillance for workers at risk.
