Many jobs require workers to use power tools or vibrating equipment every day. Over time, that constant vibration can cause a serious medical condition known as Hand-Arm Vibration Syndrome, or HAVS.
Hand-Arm Vibration Syndrome is a condition that affects the nerves, blood vessels, and muscles in the hands and arms. It develops after repeated exposure to vibration, usually from handheld tools. HAVS does not happen overnight. It builds up slowly, often over months or years of doing the same type of work.
One of the most common symptoms is numbness or tingling in the fingers. Some workers notice that their fingers turn white in cold weather. This is sometimes called “vibration white finger.” Others experience a loss of grip strength, clumsiness, or difficulty picking up small objects like coins or screws. As the condition gets worse, the damage can become permanent.
How HAVS Develops at Work
HAVS is most often caused by regular use of vibrating tools such as jackhammers, grinders, sanders, drills, impact wrenches, and chainsaws. The vibration from these tools travels from the hand into the arm and can damage small blood vessels and nerves.
The risk increases when workers use vibrating equipment for long periods without breaks, in cold environments, or without proper protective equipment. The longer and more often a worker is exposed to vibration, the higher the chance of developing HAVS.
Because the condition develops slowly, many workers do not connect their symptoms to their job right away. They may think their hands are just tired or that numbness is temporary. By the time they seek treatment, the condition may already be advanced.
Jobs That Are Higher Risk
Certain professions are more likely to lead to HAVS. Construction workers frequently use jackhammers and power drills. Factory and assembly line workers may use vibrating hand tools every shift. Mechanics often use impact tools. Landscaping and tree service workers may operate chainsaws and other vibrating equipment. Even some warehouse and manufacturing jobs involve long-term exposure to vibration.
Diagnosis and Treatment
There is no single test that proves HAVS, but doctors can diagnose it based on your symptoms, work history, and physical examination. Nerve testing and other studies may be used to rule out similar conditions.
Treatment usually focuses on stopping or reducing vibration exposure. This may mean changing job duties or using different equipment. Doctors may recommend medications to improve circulation or physical therapy. In more serious cases, permanent nerve or vascular damage can occur. The earlier HAVS is diagnosed, the better the chances of preventing long-term damage.
Illinois Workers’ Compensation and HAVS
Under Illinois workers’ compensation law, you are entitled to benefits if your job caused or contributed to Hand-Arm Vibration Syndrome. This includes 100% payment of medical bills, wage benefits if you cannot work, and compensation for permanent damage to your hands also known as a settlement. What your case is worth depends on a lot of factors including your wages and how severe the injury is.
HAVS cases are often disputed by insurance companies that argue that your symptoms are due to aging, diabetes, or another non-work-related condition. They may also claim there is not enough proof that your job caused the problem.
That is why it is important to speak with an experienced Illinois workers’ compensation attorney. A lawyer can help gather evidence, make sure your claim is properly filed, and represent you if your case needs to be heard before the Illinois Workers’ Compensation Commission.
