Hand-Arm Vibration Syndrome (HAVS), also known as Jackhammer Syndrome, is a neuromuscular disorder affecting the hands of construction, mining, forestry, and manufacturing workers that use heavy power tools on a regular basis. According to the College of Science, Technology, Engineering and Mathematics at Texas A & M University-Texarkana, HAVS affects nearly half of the two million American workers exposed to heavy power tools, such as jackhammers, grinders, riveters, drills, and chain saws.
The first symptoms to appear are tingling and numbness in the fingers and hands. Many workers affected by HAVS believe the symptoms are temporary and continue to work with high-powered tools without seeking medical intervention. As time goes on, the disorder progresses and causes pain, blanching of the fingers, and loss of strength in the hands as damage to the nerves and blood vessels increases. Once a worker’s fingers begin turning white, the disorder is irreversible.
In some cases, gangrene can develop and require amputation of the fingers or hands. Damage to the nerves and blood vessels leads to restricted blood flow and sensitivity. Workers with advanced HAVS can lose feeling in their fingers and hands, which can lead to severe infection and gangrene. When the infection reaches the bone, amputation is the only way to stop the progression of the gangrene.
Medical intervention and physical therapy can reduce the damage caused by HAVS, but only in the very early stages of the disorder. Reducing exposure to high-powered tools is necessary to protect workers showing signs of HAVS. Failure to address the damage caused by continuous exposure to intense vibrations will result in permanent damage and disability.
Employers are legally responsible to provide a safe working environment that is free from unnecessary hazards. For those in the construction and manufacturing industries, using power tools with lower handle vibration mechanisms and reducing the amount of exposure workers have to high-vibration equipment is essential for preventing HAVS. The American Society of Safety Engineers’ Professional Safety Journal and the Occupational Safety and Health Administration (OSHA) recommend the following safety practices to reduce the damage caused by high vibration equipment:
Construction and manufacturing employers can significantly reduce the number of HAVS victims by investing in low-vibration equipment. New technology on jackhammers, riveters, chain saws, and drills reduce the intensity of vibrations on the hands and fingers.
