1 ELECTRICAL SAFETY INSPECTION REPORT AKH APPARELS LIMITED 128 Hemayetpur, AKH Tower, Savar, Dhaka-1340, Bangladesh. Factory List: 1. AKH Apparels Limited Inspected by: Deonarayan Khatiwara Report Generated by: Deonarayan Khatiwara Inspected on June 26, 2014

2 SUMMARY AKH Apparels Limited is established in two buildings. One is a six storied and the other is a four storied building belonging to the factory owner. Six storied building was constructed in 2008 and utilization was made from It has the floor area of 107,000 sq.ft and the height of the building is 65 ft. Four storied building was constructed in 2013 and still under finishing stage. The total floor are of the building is 40,000 sq.ft. and the height of the building is 40 ft. In a small shed housing, the transformer is attached to the six storied building. 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. AKH Apparels Limited Page 2 of 7
