surroundings wherein the oscillations of an operational vehicle in movement are conveyed to human beings by supporting handles, walls, floors, and seats. These vibrations can have mechanical impacts on the human body which are alike to those elicited by acceleration. The strength of the vibration impacts relies on the range of frequency of the vibration force and its correlation to the body's dynamic reaction.
VIBRATION ENVIRONMENT: "The vibration environment will be observed and reevaluated when at least twenty-four hours have passed."
