P-390 Evaluation of Vibratory Ambiences of the Whole-Body System in a Container Ship Driver Within a Port Terminal

Introduction Vibrations are associated with numerus hazards for the health of workers, particularly those relating to musculoskeletal disorders (MSDs). The objective of our study is to identify and measure whole-body system vibrations encountered when driving container ships as well as to evaluate their possible harmful effects on health. Method This is a metrological study for the measurement of whole-body system vibrations in a male container ship driver in a port terminal carried out in 2018 using two sensors, one for the seat and another for the floor, both connected to an analyzer. Results The duration of the measurement was 01h05min during which the driver had moved 30 centenarians over small distances. The effective weighted accelerations obtained over the entire activity recorded were for the three axes X (anteroposterior): 0.28 m/s², Y (lateral): 0.29 m/s², Z (vertical) seat: 0.30 m/s² and Z (vertical) of the floor: 0.25 m/s. The weighted equivalent acceleration was Aeq: 0.41 m/s². The daily exposure value was Aeq(8): 0.37 m/s². Discussion and conclusion The exposure values found remain lower than the values triggering preventive action, however adequate occupational health care could detect harmful effects on health from these vibrations even before the thresholds eligible for initiating preventive actions are exceeded.
