According to Sun et.al (2006), there are four cost components that are important in estimating the indirect cost
which are productivity cost, worker replacement cost, legal and administrative cost and investigation cost [14].
Nevertheless, we proposed to include another two cost components which are product damage cost and machine
equipment damage cost. From our literature review and observations these two components certainly will add
financial burden to the company during the event of accident and should not be neglected in estimating the cost.
There are possibilities of machine breakdown when accident happened and work-in-progress product also can be
damaged due to interruption of manufacturing process. The details for each cost components are shown in Table 1.
