2 SUMMARY The West Knit Wear Limited factory is established the two (2) adjoined buildings and a shed is shared by other factories (4 other factories). The Building-1 was reportedly built in 2007 and Building-2 in 1996, and started operation in 1997 and 2008, respectively. Both buildings are six stories high and approved and built for industrial purposes and at the time of survey the factory reportedly had 750 workers. The factory occupies floors in both Building -1 and in Building 2 and share utility shed. The Factory was surveyed for electrical safety by Woosun Energy and Construction Co., Ltd. (WEC). The purpose of the survey was to identify significant electrical safety issues and to provide recommendations for remediation based on applicable standards specified by the Accord. The scope of this initial electrical safety inspection was limited to the review and identification of major electrical safety issues. The inspection did not include identification of minor deficiencies, which will be further addressed as part of follow-up inspections. Table below summarizes the major electrical safety issues identified during the inspection. Recommendations have been provided to address each issue. An implementation schedule shall be developed by the factory to remediate each of the findings. The specific timing of improvements, including any requested extensions due to design / installation constraints, shall be submitted to the Accord for approval. Page 2 of 15

3 FINDINGS AND RECOMMENDATION E- 1 Cables connected to MCCBs without terminals Cables terminating at MCCBs must be installed with cable lugs/terminals of required size and rating.
