1 ELECTRICAL SAFETY INSPECTION REPORT ACTIVE COMPOSITE MILLS LTD. Dewan Idris Road, Zirabo, Ashulia, Savar, Dhaka, Bangladesh Factory List: 1. Active Composite Mills Ltd. Inspected by: Hemlal Report Generated by: Hemlal Inspected on July 6, 2014

2 SUMMARY Active Composite Mills Ltd. (Rising Group) factory is established in a self-owned 7-storied (G+6) building. The building was constructed as industrial structure. The factory was purchased by Rising Group in 2008 and started operation in Total number of workers in the factory as reported during inspection is 1,200. 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. Active Composite Mills Ltd.

4 Finding No: E- 2 GENERATOR ROOM Generator installed in room below ground level. Existing generator installed at a level below ground level must be raised above minimum local floor level. 3 months Generator room. Finding No: E- 3 GENERATOR ROOM Cables terminating to generator output terminal box laid on cable ladder without cover. Install a metallic (checkered plate) cover to the existing cable ladder to protect the cables from physical damage from falling object. Cable terminating at generator terminal box. Finding No: E- 4 SWITCH BOARD & PANELS Panel base plates removed to allow cable entry (Typical). Panel base plates must be installed, at all time, and cable(s) entering panel must be firmly fixed with cable gland. LT panel in electrical room. Active Composite Mills Ltd. Page 4 of 10

5 Finding No: E- 5 SWITCH BOARD & PANELS Excessive heating of protective device (MCB) inside panel. Arrange periodic inspection & thermal scan to identify the cause of excessive heat-rise and take action accordingly. Replace device if necessary. 20A TP MCB inside 1 st floor MDB Finding No: E- 7 SWITCH BOARD & PANELS Panel body is not provided with earth connection. Panel doors not connected with earth bond. (Typical). Earthing bus bar and earthing cable must be provided to each panel according to BNBC regulation (min size 14SWG, 16mm 2 for main conductor sizes 16-35mm 2 ; main conductor size above 35mm 2, the earth conductor must be at least half the main conductor). PFI panel in electrical. Active Composite Mills Ltd. Page 5 of 10

6 Finding #: E- 8 CABLE & CABLE SUPPORT Cables connecting to machines are laid on floor without protection (Typical). Cables connecting to machines must be protected in cable trench or rigid conduit. Use steel pipe/cable tray to ensure the mechanical protection of cable laid on floor otherwise cable insulation may damage due to falling object or stepping of occupants onto it. Remediation Time frame: Input cable to boiler. Finding #: E- 9 CABLE & CABLE SUPPORT Circuit wiring supported in flexible PVC conduit is drawn at low height over walkway (Typical). Wiring in flexible PVC conduit must be additionally supported by rigid conduit or cable tray. The wiring must rise vertically along wall, continue horizontally on ceiling and drop vertically along wall or column support. Wiring shall not be drawn overhead half way across walkways. Remediation Time frame: Circuit wiring in production floor. Finding No: E- 10 CABLE & CABLE SUPPORT Cables passing through building wall are not protected (Typical). Use cable tray or conduit to pass cables through wall and seal the unused openings by fire rated materials. Cable entry/exit through wall in production floor. Active Composite Mills Ltd.

7 Finding No: E- 11 CABLE & CABLE SUPPORT Cable trench covered by Bakelite sheet. Existing raised cable trenches inside building must be covered with protective covers (concrete slabs or checkered plates). Cables in raised cable trenches. Finding #: E- 12 WIRING Wiring in flexible PVC conduits together with wiring in PVC conduits are disorganized and not supported and protected (Typical). Wiring system must be neatly done and wires/cables inside conduits must be sufficiently protected and supported. Provide cable tray made of noncombustible material preferably metal to additionally support and protect the conduits, cables & wires. Ensure the tray is covered with noncombustible material so that it prevents ingress of dust and debris. 3 months Sub-main and distribution wiring in factory building. Active Composite Mills Ltd.

8 Finding No: E- 13 WIRINGS Cable raceways not installed/maintained properly, end cover not installed (Typical). Thoroughly clean all the combustible materials like dust, lint and yarn from cable raceways, arrange the wires properly and the raceways must be covered with all its accessories like bends, junction, end cover, top cover, etc., to prevent ingression of lint and dust. Wires supported in metallic duct in production floor. Finding No: E- 14 WIRINGS Wires exposed while transiting between different wiring systems (e.g., Casing capping to flexible conduit or wiring ducts) (typical). The PVC/rigid pipe(instead of flexible conduit) must be used for wiring. The wiring must be continuous through-out its length and properly supported (clamped with saddle, at regular interval of 600 mm). The conduit shall run vertically or horizontally, shall never at angle. Use appropriate size junction box at the transiting junction. Wires transiting from casing capping to flexible conduit in production floor. Active Composite Mills Ltd. Page 8 of 10

9 Finding No: E- 15 EQUIPMENTS Large exhaust fans in production floors are directly controlled by the MCB (typical). The exhaust fans may be controlled by Direct- On-Line (DOL) switch. Exhaust fan in production floor. Finding No: E- 16 BOILER & COMPRESSOR Wirings in flexible PVC conduit in boiler room. Wires close/attached to boiler and generator must be protected from external heat and moisture by metallic heat resistant conduits. If possible, keep sufficient clearance between heat sources and cable/wires. Wires in flexible PVC attached/near to boiler. Finding No: E- 17 CABLES & CABLES SUPPORT Wires/cables passing through window grills. Cables must be protected, supported and installed through a safe route. Existing cables passing through window and ventilators must be removed. Earth wire in flexible PVC conduit. Active Composite Mills Ltd. Page 9 of 10
