1 ELECTRICAL SAFETY INSPECTION REPORT. House 8 & 10, Road 3, Section 7, Mirpur Industrial Area, Dhaka, Bangladesh Factory List: 1. Alliance Garments Ltd. Inspected on May 5, 2014

2 ELECTRICAL SAFETY INSPECTION REPORT. MIRPUR, DHAKA 1. INTRODUCTION 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. 2. LIMITATIONS The information in this electrical safety inspection report was obtained during a visit to the facility and during interviews with local factory management. It has not been possible to provide independent verification for all the information and data collected, and, therefore, WEC cannot accept general responsibility for omissions or errors arising from inaccuracies in this report from the information obtained. The findings and recommendations in this report are not intended to imply, guarantee, ensure or warrant compliance with any government regulations. Additionally, the results do not imply in any way that compliance with the findings or recommendations as stated in this report will eliminate all hazards, risks or exposures or that hazards, risks or exposures not referred to in this report do not exist. Compliance with the findings and recommendations stated in this report does not relieve the factory owner from obligation to comply with specific project requirements, industry standards, or the provisions of any local government regulations. 3.

4 5. Building Data a. General: The industry is housed in a 6-storied building reportedly constructed in 1996 and started production from The building was initially on rent but the management of Alliance Garments Ltd. subsequently purchased the property. As reported, the building was originally approved and built for industrial purpose. The detailed floor-wise utilization of the building as informed by the factory representatives during inspection is: Building: Gnd.floor: 1st floor: 2nd floor: 3rd floor: 4th floor: 5th floor: Bonded Warehouse, Day Care, Doctor, Boiler, Substation Cutting & Sample section & Office Sewing section (2 sewing lines) & maintenance room Finishing section, Spot room Sewing section (2 sewing lines) & maintenance room Sewing section (1-line), Finished goods, Inspection room b. Floor Layout Information: The total floor area of the building, as reported during inspection is 32,200 sqft. The floor plan of ground floor is shown in Figure 1. Figure 1: Floor plan - Ground floor The floor area of all floors is the same while the room layout differs in different floors. The floor plan (room layout) of first floor is shown in Figure 2.

Electrical System: The main source of power to Alliance Garments Ltd. is 11kV DESCO grid which is tapped from overhead pole by a underground cable and connects to a 315 kva, 11/0.400kV power transformer (Figure 4) of the factory's electrical supply system.

6 Figure 4: Transformer in Ground Floor The factory has one stand-by Diesel Generator set having generation capacity of 250 kva, shown in Figure 5. Reportedly, the generators have to run about 1.5 to 2.5 hours everyday. Figure 5: Generator in the shed attached to ground floor of factory building The grid power is received at the LT Switchgear panel and further linked with two different Change-Over-Switches (COS). On the other side, two outputs from generator also link to the same COSs. A power factor improvement unit is also connected at the main LT panel of the supply system. Figure 6 shows the electrical system of the factory in the form of single line diagram. Page 6 of 16

7 Figure 6: Single Line Diagram of the electrical supply system d. Electrical Installations: The generator output as well as the DESCO output are connected to COS that deliver power to SDBs in different floors on priority basis depending upon the load requirement. Figure 7 shows the COSs placed on one side of the generator room and used to switch-over power between generator output on one side and DESCO/Transformer LT output on the other side. COS-1 supplies to the sub-distribution boards(sdb) of ground floor to 3rd floor while COS-2 supplies power to 4th to 6th floor SDBs. Figure 7: Change-Over-Switch panels The main distribution cable from LT Switchgear or/and COSs to Sub-distribution boards of various floors of the building are run either bare or in PVC conduits. The circuit wiring and point wiring for lights and machine points in production floors is conveyed over wooden wiring ducts except in 5th floor where newly installed aluminium channel ducts have replaced the old system. In other areas and also for fan points in production floors, the wiring is a mix of surface PVC casing-capping, surface PVC conduit, and traces of concealed wiring. Page 7 of 16

Figure 9: Power distribution board - production floor e. Operation and Maintenance: Routine operation & maintenance of electrical system is reportedly done by electrical maintenance team of the factory. The team consists of Mr. Abul Hossain (Electrical In-charge) and two other trained electricians. The electrical maintenance team is also responsible to carryout upgrading work of electrical instalations including wooden duct replacement, improvement work of SDBs & DBs, cable main system, etc. Major maintenance of Transformer, if any, is the obligation of DESCO & EnergyPac that reportedly carryout scheduled maintenance. In the event of any major repair/maintenance need on Generator, the factory call the local agents or service provider of Perkins. Page 8 of 16
