Warning! Power Tools Hurt Hands

Physiologists Link Power Tool Use and Vibration-Induced Injuries, Recommend Techniques and Protective Gloves

October 1, 2010

Physiologists warn that using power tools for an extended period of time can cause damage to the hands. One million workers fall victim to hand-arm vibration syndrome each year, losing sensation and sometimes fingers from severely reduced circulation. To protect workers, scientists simulate the vibrations in a lab to learn more about how the movement affects the body. A large shaker system is used to test anti-vibration gloves and make recommendations to glove manufacturers to improve the protective gear. Experts advise workers to wear anti-vibration gloves with gel inserts or air bladders, to take breaks while working and to watch the tightness of their grip -- using the tools may lead to a harder grip, which can also cause injury.

WHAT IS ERGONOMICS? This is a branch of science that strives to design the job and equipment to fit the worker, rather than the other way around. In the modern office, it most commonly relates to the physical stresses placed on joints, muscles, nerves, tendons, bones, even hearing and eyesight, along with other environmental factors that can adversely affect comfort and health. Ergonomics deals with the interaction of technology and work environments with the human body, and involves such things as anatomy, physiology, and psychology in the design of chairs, desks, computer accessories, the design of car controls and instruments -- in short, any kind of product that could help relieve potential repetitive strain from a given job or task.

TOOL USE SAFETY TIPS: Inspect electrical and hand tools before use. When it's heavy get some help. Don't be a hurt hero. Never smoke around flammables. Watch out for pinch points and sharp edges. Keep your work area neat and clean. Avoid horseplay -- someone always gets hurt. Wear personal protective gear properly and whenever required. Check the label and read the manufacturer's instructions before use. Ask questions whenever you're in doubt.
