What is Hand Arm Vibration Syndrome (HAVS)?
Hand-arm vibration syndrome (HAVS) is a debilitating condition caused by repeated exposure to vibration. It encompasses a range of symptoms, including vibration white finger (VWF), carpal tunnel syndrome (CTS), and musculoskeletal disorders. HAVS can lead to long-term disability, making it crucial to understand its causes, symptoms, and available treatments. Additionally, exploring preventive measures such as sandblasting can significantly reduce the risk of HAVS for those working with vibrating tools and machinery.
Causes
HAVS occurs as a result of prolonged exposure to vibration. Common sources of vibration include hand-held power tools like drills, saws, and grinders, as well as vibrating machinery such as pneumatic hammers and needle scalers. Even around the home there is exposure to HAVS. The humble lawnmower, line trimmer and other powered garden tools will give you tingles and numbness in your hands after a full day of work.
While the exact threshold for developing HAVS varies, it is generally believed that extended exposure to high levels of vibration poses the greatest risk.
Lately, with the advances in technology, there are now metering devices you can wear, like a watch, to monitor your own or staff’s levels of exposure to HAVS-causing practices. Other monitoring devices include sensors that attach directly to the tool being used. Many industries and workplaces have already begun testing, and the results were shocking.
Symptoms of HAVS
The symptoms of HAVS range in severity and can have a significant impact on a person’s quality of life. Early signs may include tingling, numbness in the fingers, pain in the hands and arms, and reduced grip strength. As exposure to vibration intensifies, symptoms can progress to vibration white finger (VWF), wherein the fingers turn white in response to cold temperatures, carpal tunnel syndrome (CTS), which involves compression of the wrist nerve resulting in pain, numbness, and tingling in the hand, and musculoskeletal disorders such as arthritis and tendinitis.
Diagnosis
Diagnosing HAVS relies on a combination of symptoms, medical history, and exposure to vibration. Although there are no specific tests for HAVS, healthcare professionals may employ nerve conduction studies and blood tests to support the diagnosis.
Treatment
While there is no cure for HAVS, various treatments can help manage its symptoms. These treatments may include avoiding further exposure to vibration, taking medication to alleviate pain and inflammation, wearing protective gloves, and undergoing physical therapy to enhance range of motion and strength.
Prevention of HAVS
Preventing HAVS is of utmost importance, and there are practical steps individuals can take to mitigate the risks. For those working with vibrating tools, adopting the following preventive measures is crucial:
- Use tools with low vibration levels: Opting for tools specifically designed to minimise vibration can significantly reduce the risk of developing HAVS.
- Take regular breaks: Frequent breaks during work hours allow the body to recover from vibration exposure and reduce the accumulation of damage.
- Wear protective gloves: High-quality gloves act as a barrier, absorbing and reducing the transmission of vibration to the hands.
- Train staff in the correct use of tools and more importantly, select the right tool for the job.
Sandblasting: One effective measure to mitigate the risk of HAVS is to incorporate sandblasting techniques into work processes. Sandblasting involves using compressed air or steam to propel abrasive materials at high speeds onto surfaces, effectively removing unwanted coatings or contaminants. This method eliminates the need for handheld vibrating tools, thereby minimising the exposure to harmful vibrations. Sandblasting also eliminates risky activities like using power tools in overhead or restricted spaces.
Sandblasting is particularly beneficial as it offers numerous advantages beyond preventing HAVS. It is a highly efficient and versatile process that can be applied to various materials and surfaces. Whether used in industrial settings or for household projects, sandblasting ensures thorough cleaning, improves adhesion for coating applications, produces a uniform finish, and prepares surfaces for repair or restoration.
By implementing sandblasting techniques, individuals can reduce the possibility of HAVS while simultaneously benefiting from an effective and efficient surface preparation method.

Hand-arm vibration syndrome (HAVS) is a serious condition that can severely impact an individual’s quality of life. Understanding its causes, symptoms, and available treatments is essential for early detection and management. Moreover, prioritising preventive measures is crucial to mitigate the risk of HAVS.
Sandblasting stands out as an effective solution, providing a safe and efficient alternative to vibrating tools, thereby reducing exposure to harmful vibrations. By incorporating sandblasting into work processes, individuals can safeguard their health while achieving outstanding results in surface preparation and restoration projects. Stay informed, take necessary precautions, and embrace sandblasting as a valuable tool for both HAVS prevention and improved work efficiency.
