Abstract
This study aimed to fill the research gap on whole-body vibration (WBV) exposure of dumper operators in India, conducting a comprehensive investigation into specific phases of dumper operations. Results indicated that 59% of operators exceeded lower limits, with 90.8% exposed to vibration levels surpassing the lower limit for A(8) and VDV(8) values. Frequency analysis identified peaks aligning with crucial body parts, corroborating epidemiological findings. Statistical analysis (ANOVA) demonstrated significant differences in WBV exposure across activity groups (p < 0.001), dumper speeds (p < 0.001), and haul road conditions (p < 0.001). Optimising driver speed, improving haul road surfaces, and regular vehicle maintenance are some recommendations to reduce WBV exposure among dumper operators.
