HAVS is a insidious disease that affects many people who use vibrating tools and equipment like needle guns, pneumatic tools, jackhammers, and chainsaws. Exposure to cold weather can exacerbate the disease, and left unattended or undiagnosed, it can lead to blanching of the fingers. In extreme cases, it can lead to the medical amputation of fingers. The HAVS video is stored at the DOD imagery site (dodimagery.afis.osd.mil), and it can be ordered at no cost to the requestor (government activities/commands).
