| Popis: | Studies related to a systematic approach for intervention design to reduce whole-body vibration (WBV) exposure are scarce. This study presents a systematic approach to identifying, selecting, and prioritizing safety interventions to fulfill that research gap.A total number of 130 vibration readings for dumper operators was taken from two surface iron ore mines to identify significant determinants of WBV exposure. Initially, age, weight, seat design, awkward posture, machine's age, load tonnage, dumper speed, and haul road condition were hypothesized as determinants. Data were collected through standardized questionnaires and field-based observation. A multivariate statistical approach is applied for the practical use of the intervention program.As some of the hypothesized factors were correlated, exploratory factor analysis (EFA) followed by multiple linear regression (MLR) was used to investigate their association with WBV exposure. As per EFA results, hypothesized factors were clubbed under individual, ergonomics, and occupational factors. The occupational and ergonomics factors were found to be significantly associated with WBV exposure through MLR and were used to form safety interventions to reduce WBV exposure.Our methodological approach is original in the occupational-health-research area and can be helpful to tailor the safety interventions for unit-level with minimum effort. |
