1 ELECTRICAL SAFETY INSPECTION REPORT BOVS APPARELS LTD. JAMUR MUCHIPARA, HEMAYETPUR, SAVAR, DHAKA, BANGLADESH Factory List: 1. BOVS APPARELS LTD. Inspected on April 13, 2014

2 SUMMARY The Bovs Apparels Ltd is housed in a eight storied building. Construction up to the 3 rd floor was completed in 2012 and the remaining four storeys are under constructions. 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. Bovs Apparels Ltd. Page 2 of 11

3 FINDINGS AND RECOMMENDATIONS Finding #: E- 1 TRANSFORMER ROOM Transformer guarded with wire mesh fencing. Construct a fire rated separate dedicated room for the transformers providing necessary clearance around it. Assign a qualified engineer to design a required transformer room according to BNBC 2006, Section months Transformer guarded with wire mesh fencing Finding #: E- 2 TRANSFORMER ROOM Oil cup below transformer breather is empty. Breather oil cup must be filled with transformer oil to the required level as instructed by the manufacturer. Oil cup of transformer breather kept empty Bovs Apparels Ltd. Page 3 of 11

4 Finding #: E- 3 SERVICE LINE Cables laid directly on concrete floor without protection. Install cable tray with protective cover to support and protect the cables laid on the floor and cables supported on the existing cable ladder. Cables laid on floor not protected Finding #: E- 4 Unused openings in the base plate of manual changeover switch. Make circular hole at the base plate/top plate of panels and provide cable gland according to the respective cable size for cable entry and exit so that the cables are not stressed on the sharp edges of the hole of panels. Provide covers (of noncombustible material) if any additional gap remains after installing cable glands to make the panel dust and vermin proof. Changeover switch panel not dust and vermin proof Bovs Apparels Ltd. Page 4 of 11

5 Finding #: E- 5 No use of cable gland in the panel top plate and unused openings found. Make circular hole at the base plate/top plate of panels and provide cable gland according to the respective cable size for cable entry and exit so that the cables are not stressed on the sharp edges of the hole of panels. Provide covers (of noncombustible material) if any additional gap remains after installing cable glands to make the panel dust and vermin proof. Changeover switch panel not dust and vermin proof Finding #: E- 6 CABLE & CABLE SUPPORTS Cables subjected to and drawn from the cable ladder not supported. Install a vertical cables tray or ladder with protective cover to lift the cables from the ground to ladder hung from the ceiling and fix and arrange the cables tightly. Cables not supported and fixed Finding #: E- 7 Panel base plates not installed. Install the panel base plate to make it dust and vermin proof. Panel not dust and vermin proof Bovs Apparels Ltd.

6 Finding #: E- 8 WIRINGS Cables passing through window grill not protected. Install a covered cables tray to route and protect the cables through window grill safely. Provide earth connection to the cable tray to keep it earth potential all the time (both the normal and abnormal condition). Cable passing through window grill not protected Finding #: E- 9 CABLE & CABLE SUPPORTS Cables encased in flexible pipes passing through wall not protected and remaining gaps not sealed. Cables passing through permanent walls must be protected in covered cable tray/ steel pipe /PVC pipes and supported near the panel entry; the remaining gaps after the passage of conduits must be sealed with fire resistance materials. Cables passing through wall not protected. Finding #: E- 10 Cables encased in flexible pipe terminated to distribution panel, not supported. Use rigid PVC/Steel pipe for carrying cables into the panel; run vertically or horizontally never at an angle and support them at regular intervals with saddle clamp.

7 Finding #: E- 11 WIRINGS Cables hanging from wall not protected. Install covered cable tray to route and protect the cables hung from wall. Cables hanging from wall not protected Finding #: E- 12 Electrical panel enclosure including it s door not connected to earth. Panel enclosure including its door must be connected to earth using green cables preferably earth braid so that the metallic door remains at zero potential all the time. Practice earth continuity test to insure earth continuity to panel and loads enclosure and keep record. Panel enclosure not connected to earth Finding #: E- 13 Barrier/separators not installed between different phases of MCCB. Install separators between different phases of MCCB to avert flashover. Standard separators provided by the MCCB manufacturer must be used. Damaged MCCB Bovs Apparels Ltd. Page 7 of 11

8 Finding #: E- 14 Multiple cables terminating to a single lugs as well as terminated to single pole of MCCB. Select proper sized single cable for each pole of MCCB.

Cables passing through permanent walls must be protected in covered cable tray/ steel pipe /PVC pipes and supported near the panel entry; the remaining gaps after the passage of conduits must be sealed with fire resistance materials. Cables and sanitary pipes a passed together simultaneously through wall Finding #: E- 17 CABLE & CABLE SUPPORTS Disconnected cables from equipment are left naked. The used cables on the ceiling must be tapped properly with electrical tape to avoid short circuit and electric shock. The cables must be protected and supported above floor. Wires disconnected from load/equipment left naked Finding #: E- 18 Improper phase separators/barriers installed between MCCB poles. Install standard separators provided by the MCCB manufacturer to avoid flashover. Improper phase separators not installed between MCCB poles Bovs Apparels Ltd. Page 9 of 11

10 Finding #: E- 19 Electrical panel found congested. Additional panels may be installed to distribute to reduce wiring and protective devices from the existing panel.
