SUMMARY
Ahsiar Fashions Ltd. factory is established in a 3-storied (G+2) owned building at Shovapur, Savar, Dhaka.
The ground and 1st floors of the building are of similar size, and the 2
nd floor is much smaller. The building
was constructed as industrial structure in 2007 and the factory started production in 2012. The factory had
approximately 370 workers at the time of 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 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.
