1 EQUIVALENT INITIAL ELECTRICAL SAFETY ASSESSMENT Factory Assessor: Plot #92 (Partial) DEPZ Extention Area-02 Ganakbari, Ashulia, Savar Uttaron 10 Feb 2014 The Alliance for Bangladesh Worker Safety Page 1/10

2 10 Feb 2014 Introduction to the Report The following report contains a site profile and summary of non-conformities identified during an onsite assessment commissioned by the Alliance for Bangladesh Worker Safety (Alliance) and conducted by a third-party Qualified Assessment Firm (QAF). The assessment was conducted against the Alliance for Bangladesh Worker Safety Assessment Protocols (APs) and Fire Safety and Structural Integrity Standard, which is harmonized with the factory assessment guidelines developed by Bangladesh University of Engineering and Technology (BUET) for the Bangladesh National Tripartite Plan of Action (NTPA). The goal of the Alliance process is to provide clear and practical technical requirements by which Bangladeshi Ready Made Garment (RMG) Factories producing for Alliance members may be consistently and fairly evaluated for fire, structural, and electrical safety in a non-duplicative manner. Each assessment will prompt action plans that will be used by RMG factories to systematically and sustainably improve safety conditions for garment workers. Beyond tracking and reporting on action steps taken in a transparent manner, the Alliance organization and its members will seek to further support factory improvements through technical assistance, training, implementation support for functional Worker Committees, and in some cases financial assistance and wage support for workers if factories are closed for remediation. The contents of the report do not constitute a guarantee of compliance with the applicable laws, the Alliance Standard or the absolute or continued safety against fire, electrical and/or structural integrity issues that may lead to injury or loss of life. The report is designed to provide a non-exhaustive summary of risk issues, based on a limited sampling and duration of time onsite by the named QAF. Neither the QAF nor the Alliance can certify or guarantee the quality, outcome, or effectiveness of actions taken in response to the report.

Alliance Standard Part 10 Section Electrical Inspections Electrical System Conditions Shielding or additional insulation is provided for wiring exposed to external heat sources. High In order to avoid the effects of heat from external sources one of the following methods shall be used to protect wiring systems: (1) shielding; (2) placing 900 mm (36 in.) from the source of heat; (3) selecting a system with due regard for the additional temperature rise which may occur; (4) local reinforcement or substitution of insulating material. Visual Assessment: Insulation is not provided for the cables and wiring where needed. Provide insulation for cables and wiring where required. 31 Aug 2014 Alliance Standards Part 10 Section External heat sources.
