Abstract: 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.
