No Bad Vibes


Are you familiar with Hand-Arm Vibration Syndrome (HAVS)? This is a common occupational disorder in the industry, brought on by long-term exposure to high vibrations from tools such as impact wrenches and grinders.

Operators exposed to this situation may suffer irreversible damage if they are not properly cared for. This is why it is essential to be on the alert for symptoms.

Below are some of the injuries classified as HAVS symptoms:


1. Vascular injuries: Raynaud's phenomenon

This condition happens when the finger arteries thicken, narrowing the blood flow area. With this pathway restricted, the blood cannot reach the injured spots.

The most common vascular disorder is Raynaud's Phenomenon, where the affected fingers become white due to insufficient blood circulation. This is most noticeable in cold temperatures when the body restricts blood supply to the extremities.


2. Nerve damage: Numbness

Nerve cells may also be harmed by vibration, resulting in numbness in the fingers. The damage may be reversible in the initial stages, but long-term exposure will permanently impair them.

This injury leads to the most complaints, as those affected are limited in their day-to-day activities. Basic tasks like buttoning a shirt, grabbing coins from a flat surface or sewing are made difficult or impossible.

Carpal Tunnel Syndrome (CTS), which causes hand tingling, is also tied to vibration exposure, but is not solely a vibration injury. Working with a bent wrist can also trigger CTS. The symptoms are broadly like nerve injuries.


3. Musculoskeletal disorders: Straining and fractures

Musculoskeletal disorders are brought on by working with high-force percussive tools (e.g., jackhammers). The vibration is carried through the hand and arm, resulting in wear and tear and even joint fractures.


Full guide: A whitepaper on effective ways to prevent the syndrome

All Hand-Arm Vibration Syndrome cases compromise the operator's hand mobility and ultimately impact their work performance.

Swedish and British companies have estimated the financial burden of a vibration injury at around 50.000 euros - this includes lower productivity, hiring and training a new operator and finding new tasks for the injured employee.

Fortunately, there are several ways to keep operators healthy, boost productivity and uphold a high standard in product quality. The most important aspect is always to properly control exposure time and use machinery with special devices aimed at minimizing vibrations.

Bearing in mind how important ergonomics is, we have compiled a whitepaper with all the information you need to recommend effective ways of preventing Hand Arm Vibration Syndrome. Download it and check it out!
