2 SUMMARY The Mahid Apparel Ltd. factory is a ten (G+9) storied building with one basement floor. The building was constructed in 2011, and factory began production in November, The building has been approved for 9 storied mixed use building purpose. During the inspection the factory had approximately 840 workers. The generators and substation are located in a separated building owned, operated and maintained by Jaj Spinning Mills Ltd, which are sister concern of JAJ BHUIYAN Group. 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 would 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. The 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 an approval. MAHID APPAREL LTD. Page 2 of 19
