SUMMARY

Kento Asia Ltd. factory is established in a rented premises consisted of Six (6)sheds built for industrial purpose in 2008, but the officials we met were not sure of the year when the sheds were built. Factory rented the premises and started operation in 2008, and the factory, at the time of survey, reported to have about 664 workers working on regular basis.

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.
