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 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.
