Ergonomics Awareness Training for Supervisors Practice Test

True or False: High or prolonged exposure to whole body vibration decreases your chance of a back injury.

1. True

2. False

3. Only during specific activities

4. Depends on the individual

The correct answer is: False

The statement is false because high or prolonged exposure to whole body vibration is actually associated with an increased risk of developing back injuries. When an individual is subjected to whole body vibration, such as from operating heavy machinery or vehicles, the vibrations can lead to fatigue of the muscles and ligaments in the back, disrupt normal posture, and ultimately contribute to spinal disorders or injuries. Research indicates that these vibrations can affect the discs in the spine, leading to conditions like disc degeneration or herniation, thus heightening the risk of back problems. It is important for ergonomics supervisors and safety professionals to recognize these risks and implement strategies like appropriate seating, vibration dampening measures, and regular breaks to mitigate potential injuries related to vibration exposure.
