以本研究結果顯示，廢棄物清運風險改善可從落實人員教育訓練、強化設備安全防護、定期檢查設備狀況、改善作業流程、加強作業管理五大方向進行改善；作業風險值由RPN 16降至RPN 5，廢棄物事故率統計由改善前平均每月0.3件事故降至改善後每月0件事故(資料統計至103年3月)。改善後作業仍需持續PDCA達到持續改善的目的，廢棄物作業安全的提昇，可降低事故發生的機率，提昇公司企業形象與社會責任。|
Relevant statistics have shown that waste removal and transportation workers are a population that is highly subjected to danger and that has a high occupational accident casualty rate. However, compared to other workers, waste removal and transportation workers’ safety at work is often neglected. Particularly in semiconductor factories, waste takes numerous forms and requires frequent removal and transportation; therefore, any negligence during operating procedures easily produces risks of accidents and environmental pollution. Currently, waste removal and transportation tasks in factories are outsourced to contractors. To prevent accidents, potential job hazards must be assessed. Effective improvement approaches and safety management can subsequently be adopted to reduce the risks involved in waste removal and transportation. This study analyzed waste removal and transportation operations at a semiconductor factory in Hsinchu, Taiwan and investigated possible risk factors between the time the waste removal and transportation firm employees entered the factory and commenced work to the time that they left the factory. This study examined the types of waste and the work methods in the factory, and conducted failure mode and effects analysis to assess risks involved in the various operational procedures. Potential risks were ranked; factors that were not clearly harmful and those that were redundant were eliminated. Subsequently, approaches to improve high-risk waste removal and transportation operations were suggested, and the effects of implementation were monitored. This process was expected to effectively reduce enables operational risks and enhance the safety of waste removal and transportation workers. The research results indicated that the reduction of risks in waste removal and transportation operation should be pursued from five aspects: personnel educational training, facility security enhancement, regular facility examination, working procedure improvement, and the strengthening of operational management. Implementing the improvement approaches reduced the risk priority number from 16 to 5; the accident rate declined from an average of 0.3 accidents per month to 0 accidents per month (data collected until March 2014). Improving working procedures requires continual plan-do-check-acts. Reinforcing the safety of waste removal and transportation can reduce accident rates and enhance a companies’ and corporations’ images and commitment to social responsibility.
