Abstract
Sri Lanka’s apparel export industry has enjoyed epic growth levels over the past four decades and is today the primary foreign exchange earner accounting to 40% of the total exports, heavily contributing the island elevated to a middle-income country. The industry has been positioned as a socially responsible and safety complying destination for apparel sourcing. Plant maintenance plays a major role on efficiency of manufacturing process and to have apparel sectors’ recognition over safe plant operations, maintenance functions have to be well complying with safety standards. “Lockout and Tag out” sequentially are the placement of a device on an energy isolator to ensure that the energy isolator and the equipment being controlled cannot be operated until the device is removed and the equipment being tagged out shall not be operated until the tag is removed. Lockout/Tagout being very human intense, role of ergonomics in Lockout/Tagout would be inevitable. This research outlines an applied research of some of the human factor issues involved in Lockout/Tagout implementation and suggests how ergonomics would improve such issues. Being an applied research, task decomposition was performed in 3 apparel accessories manufacturing plants in south Asia including Sri Lanka where Lockout/Tagout out is being implemented to identify ergonomics gaps throughout different phases of risk assessment, formulating Lockout/Tagout procedures and providing staff training. As the outcome of this research, a series of ergonomic focus points were identified that would improve Lockout/Tagout implementation. Those focus points are presented in form of a check list that can be used as an applied tool in evaluating Ergonomics of Lockout/Tagout in manufacturing field in general.
