SUMMARY
The Ajax Sweater Ltd. is established in a 4 storied industrial (approved) building (G+3) building with a
roof top. Reportedly, the building started construction in 2006 and was completed up to 3rd floor in 2007.
The factory started its production around 2010. Total floor area of the main building is 87,000sft with
building height of 42 ft and has around 950 permanent staffs in total.
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.
