2 Alif Garments Ltd. PAGE 1 SUMMARY The seven-story factory housing Alif Textiles Ltd. & Hexa Garments Ltd. located in Dhaka, Bangladesh was surveyed for Electrical Safety on 06 December 2013 by Woosun Energy and Construction Co Ltd. This summary identifies the critical and major deficiencies that were identified during the inspection as documented in the Electrical Safety Inspection Report, dated 14 January 2014, submitted to the Accord. The factory building was surveyed 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 inspection was limited to the review and identification of critical and 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 1 summarizes the critical and major electrical safety issues identified during the inspection. Recommendations have been provided to address each issue. Reference photos are provided in Attachment 1. An implementation schedule shall be developed by the factory to remediate each of the findings in Table 1. The specific timing of improvements, including any requested extensions due to design / installation constraints, shall be submitted to the Accord for approval.

Findings and Recommendations No. Category Finding Recommendation Timeline E-1 Transformer and service line The service lines (cables) from pole mounted outdoor transformer to 6 th floor are strung without support and protection against harsh weather. E-2 Service line from another pole mounted transformer is drawn on the 2 nd floor unsupported. E-3 The remaining opening after passing the service cables through wall on 6 th floor is not sealed. E-4 440KVA Diesel Generator set Generator is located at the ground floor left of entrance with door opening towards the entrance. E-5 Cables entering/leaving the terminal box are connected without cable gland and base pate. E-6 Cables are laid directly on concrete floor. E-7 Panels Cables entering or leaving panels are connected directly to MCCBs without supports. The cables must be weather resistant and supported with steel wire. It is recommended that the cables be drawn underground from pole to the factory building. The cables must be weather resistant and supported with steel wire. It is recommended that the cables be drawn underground from pole to the factory building. The openings must be sealed corresponding to the fire rating required in the compartment/room after the cables re-drawn. Refer to fire safety recommendations; change the door opening to avoid the main entrance. Cables terminating must be fixed using cable glands and the terminal box base must be closed with gland plates. Cables run on floors must be protected and supported on cable trays or in trenches. Cables entering or leaving panels must be firmly fixed/supported at the base plate using cable glands Photo Ref E.1 E.2 E.3 E.4 E.5 E.6 E.7

Cables must be supported on cable trays/ladders or raisers and fixed firmly on the wall. The bus bar panel must be designed in accordance to the number of cables connecting and the rating of the bus bar. Phase barriers between different phases for voltage exceeding 230 volts must be installed. Joints must be avoided and wires damaged must be repaired by soldering and insulated such that it has sufficient electrical and mechanical strength. It is recommended that joints and repairing 1 (when the conductor is damaged) must be avoided. Socket outlets must be connected with separate circuit and connected with earth. Within 6 Within 6 Within 6 Photo Ref E.8 E.9 E.10 E.11 E.12 E.13 E.14 1 Repairing wiring for damaged conductor is not permitted. Repair of damaged insulation may be permitted if the engineer verifies that the wire has adequate electrical insulation and mechanical strength after repairing.

5 Alif Garments Ltd. PAGE 4 No. Category Finding Recommendation Timeline E-15 Fluorescent light fittings are not Light fittings must be safely covered (connections and fitting installed and all live parts must be wiring) and connections are covered. All metal parts/frames exposed. must be earthed. E-16 Fans and lights are extended from the same wiring and fan locations. E-17 Wiring & Cables Cables laid on floors/ceilings or walls are not protected. E-18 Cables and wirings are run through stairways. E-19 Wiring is drawn out from the conduit junction boxes for modification / extension of wirings. Every lighting circuit must not be connected/loaded more than the designed rating 2. The joints must be looped at the terminals 3. Cables run on floors must be supported on cable trays or laid in trenches. Cables on walls must be supported on ladder or raisers. Main cables passing through different floors must be separated through service shaft or enclosed in corresponding fire rated enclosures as per the compartment/room it passes through. It is recommended that stairways not be used as electrical shafts. Practice of extending existing wiring must stopped 4 and all modifications must be re-wired, by safe practices, to avoid joints in wires. Within 6 Photo Ref E.15 E.16 E.17 E.18 2 Each lighting circuit must not be connected with more than 800W. 3 Mid-span joints must be avoided in circuits (between switch & light fittings or between fittings connected in parallel. 4 Any additional points must be connected through new wiring from the distribution panel either the existing supports or installing additional supports.

6 Alif Garments Ltd. PAGE 5 No. Category Finding Recommendation Timeline E-20 Wooden ducts, without cover, are used as wiring supports in the production floors. Some insulation damages (probably by rats) can be seen in wiring. E-21 Wires are joined (mid-span and Tee joints) are made in wooden ducts and repaired/insulated using PVC insulation tape. E-22 Wiring in boiler room is not protected from external heat. E-23 Connection in terminal box is not protected and not maintained (box cover open) regularly. E-24 Wiring inside boiler control panels is not dressed and protected. Wooden ducts must be replaced with safe factory fabricated ducts. The ducts may be designed such that the wirings supported in it are safe and protected from dust and external damages. Joints in cable ducts must be avoided and where PVC insulation are to be repaired (minor damages), it must be insulated and tested (IR measurement). Wirings in boiler room must be protected from external heat 5. Wires must not be joined other than at the designated terminals. Terminals boxes must be covered to protect from dust and physical damages besides risk of electric shock to the operators. Cables and wiring must be firmly fixed to the devices and protected/supported to prevent damages (aging of insulator) due to heat from boiler. Wiring inside boiler control panel must be checked and maintained on regular basis. The wiring after maintenance must be redressed safely. Within 6 Photo Ref E.19 E.20 E.21 E.22 E.23 5 Wiring must be protected from external heat by enclosing in heat resistant covers, placing at safe distance on supports or using heat rated cables/wires.

E-26 Transitions between different wiring systems are not covered or adapted for proper joints. E-27 The openings left after passing the main cables through walls are not sealed. E-28 Conduit wiring systems crossing building expansion joints without expansion joints. E-29 Earth systems Mid-span and tee joints are made in earth conductors. Wiring system must be consistent and try to use single system from distribution board to load points. All additional points must be wired in separate conduit/duct, without crossing existing wirings. The opening (excess) remaining after passing the cables must be sealed such that it meets the fire resistant specifications. Conduit wiring must avoid crossing expansion joints and where it is unavoidable, conduit expansion joints must be used. Joint in earth conductors (midspan and tee) must be avoided. All earth connections must be distributed from earth strips installed in panels. Within 6 Photo Ref E.24 E.25 E.26 E E PVC flexible must not be used in industrial wiring of permanent nature. Where unavoidable, the flexible conduit selected must be industrial grade.
