BPSS was used to identify discomfort on workers body parts. The use of BPSS method allows the workers to
clearly indicate on their discomfort. The result confirms that these workers are experiencing LBP. However, the
extent of the LBP faced by these workers will be determined. Based on observations, the discomfort problems arise
from the MMH method practiced by the workers, as well as discomfort on upper and lower back for those working
at the loading bay. According to Ghaffari et al. (2006), repeated MMH activities, even if performed while in sitting position could potentially cause LBP and MSD. This shows that the MMH performed is hazardous and high risk to
LBP.
