P-389 Evaluation of the Vibrational Environments of the Whole-Body System in a Forklift Driver Within an Industrial Company

Introduction Vibrations constitute risk factors par excellence for musculoskeletal disorders (MSD), particularly at the spinal level for vibrations of the whole-body system. The objective of our study is to identify and measure whole-body system vibrations encountered when operating forklifts as well as to evaluate their possible association with health effects. Methods This is a metrological study for the measurement of whole-body system vibrations in a male forklift driver in an industrial company 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 01h50min. The effective weighted accelerations obtained over the entire recorded activity were for the three axes X (anteroposterior): 0.25 m/s², Y (lateral): 0.23 m/s², Z (vertical) seat: 0.71 m/s² and Z (vertical) of the floor: 0.73 m/s. The weighted equivalent acceleration was Aeq: 0.71 m/s². The daily exposure value was Aeq(8): 0.65 m/s². Discussion The exposure values found exceed the values triggering preventive action but still remain lower than the values prohibiting work. Conclusion Corrective organizational and preventive medical measures must be put in place to prevent the occurrence of the harmful effects of vibrations on the health of workers.
