2 SUMMARY The Foptex (Pvt.) Ltd. is established in a 8 storied building, but factory uses only up to the third floor on rent. The construction of factory building was started in 1997 in phase manner and completed in The production was started in The building was approved for industrial purpose. There were 247 workers present in the factory during the inspection. 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. Foptex (Pvt.) Ltd. Page 2 of 13
