Abstract
This research project seeks to study the effects of vibrations on the health of workers who operate heavy equipment. Vibrations are rapid and continuous oscillation movements that occur in objects or materials with respect to their equilibrium position and can be transmitted to the human body or to some of its parts. The frequency of vibration, which is expressed in cycles per second, i.e. hertz (Hz), affects the extent to which vibrations are transmitted to the body, both to the limbs themselves and to the rest of the body. The origin of work-related vibrations can be: machinery, hand tools, engines, vehicles, etc., due to unbalanced moving parts, turbulent flows of fluids, blows from objects, impulses, shocks, etc. The vibrations enter the body through the extremities (hand-arm vibrations) or through the rest of the body (whole-body vibrations), through the lower extremities or by sitting on a surface that emits vibrations, which can cause damage to the health of the workers exposed to them. Main effects of vibrations on workers’ health: abdominal pain, low back pain, digestive problems, urinary difficulties, lack of balance, visual disturbances, headaches, lack of sleep, etc. Vibrations affect comfort, reduce productivity and cause disorders in the physiological functions of man, leading, in the event of intense exposure, to the appearance of diseases. Specifically, this document focuses on the physical risk factors (vibrations) and their effects on the health of heavy equipment operators who are exposed to vibration levels throughout their working day.
