Proactive risk assessment and management tools for manual handling in manufacturing paving blocks

Abstrak / Ringkasan

This study was conducted on a business unit that manually
manufactured paving blocks which led to injuries involving musculoskeletal
disorders (MSDs). Data obtained from the Nordic body map of four workers,
showed that 14.81% failed to fall sick, 40.74% were partly sick, 36.3% were
sick, and 3.7 very sick. This study, therefore, proposed a RAMP (risk
assessment and management tools) method to identify and analyse work
activities. The result showed that the level of risk in paving block
manufacturing activities was 7, 13, and 15 in categories of high, moderate, and
low, respectively, with a total score of 80.40. After proper improvement, there
was a reduction in moderate and high bending duration from 34.8 to 25 minutes
and 131.55 to 95.8 minutes, respectively, with lifting frequency from 1000 to
500 times. The reduction made a total assessment score of 74.20, therefore,
further study is required to conduct layout on the workspace.
