Inspected by: Al-Amin Report Generated by: Al-Amin
Inspected on March 7th 2015
SUMMARY The A & B Outerwear Ltd. factory is established in owned three building and four shed. Building-1 is three storied; Building-2 is two storied and building three is one storied. Building-1 was constructed in 2010 and production started in same year. Building-2 was constructed in 2011 and production started in same year. Building-3 was constructed in 2011. The factory had approximately 1114 workers. 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 dealt with as part of follow-up inspections. Table below summarizes the major electrical safety issues Recommendations have been provided to address each issue.
identified
during
the
inspection.
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.
