Vibration is the mechanical oscillations of an object about an equilibrium point. The oscillations may be regular, such as the motion of a pendulum, or random, such as the movement of a tire on a gravel road. The study of the health effects of vibration requires measures of the overall "pressure waves" (vibration energy) generated by the vibrating equipment or structure.
The risk of vibration-induced injury depends on the average daily exposure. An evaluation of the risk takes into account the intensity and frequency of the vibration, the duration (years) of exposure and the part of the body which receives the vibration energy. Hand-arm vibration causes damage to hands and fingers.
Whole-body vibration can offer some fitness and health benefits, but it's not clear if it's as good for you as regular exercise. With whole-body vibration, you stand, sit or lie on a machine with a vibrating platform. As the machine vibrates, it transmits energy to your body, forcing your muscles to contract and relax dozens of times each second. The activity may cause you to feel as if you're ...
The Canadian Centre for Occupational Health and Safety (CCOHS) promotes a safe and healthy working environment by providing occupational health and safety information and advice.
Vibration-induced health conditions progress slowly. In the beginning, it usually starts as a pain. As the vibration exposure continues, the pain may develop into an injury or disease. Pain is the first health condition that is noticed and should be addressed in order to stop the injury. Vibration-induced white finger is the most common condition among the operators of hand-held vibrating ...
How can you measure vibration? A complete assessment of exposure to vibration requires the measurement of vibration acceleration in meters per second squared (m/s2).
A complete assessment of exposure to vibration requires the measurement of vibration acceleration in meters per second squared (m/s2). Vibration exposure direction is also important and is measured in defined directions. Vibration frequencies and duration of exposure are also determined. How hard a person grips a tool affects the amount of vibrational energy entering the hands; therefore, hand ...
Vibration is produced by rotating machines like chain saws and drills, and impacting tools such as a jackhammer. Bumpy roads can also cause vibration to the passengers in the car. Vibration exposure occurs when we come in contact with vibrating tools, seats or floors. The health effect appears in the part of the body that comes in contact with vibration. Hand-arm vibration can damage blood ...
