C.D.F. Design (BD). of 9

SUMMARY

C.D.F Design (BD). is located in Diganta Complex. Diganta complex consists of three multistoried buildings and seven separate sheds covering 432000.0sqft of land. The buildings and sheds were constructed as industrial structures. There were 9777 workers in the premises, during the inspection.

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.


FINDINGS AND RECOMMENDATIONS

Finding #: E- 1

Transformer located on pole.

Category: SERVICE LINE

Finding: LT cable terminating at power transformer not supported.

Recommendation:

Install covered cable tray or ladder to support the main service cables from pole mounted distribution transformer to LT panel in order to protect the cables’ insulation from any physical damage.

Remediation Timeframe: WITHIN 1 MONTH

Finding #: E- 2

Service cable entering to factory building.

Category: SERVICE LINE

Finding: Overhead service cables are not supported.

Recommendation: Install covered cable tray (supported on wall) to support the main service cables from pole mounted distribution transformer to LT panel in order to protect the cables’ insulation from any physical damage. Ensure the insulation of the cable does not get damaged during installation work.



Finding #: E- 3

Cables entering to generator panel.

Category: GENERATOR ROOM

Finding: Cables terminating to generator output terminal box are stressed and not supported.

Recommendation: Cable terminating at Generator output terminal box must be supported on riser and protected. Install cable duct to protect the generator output cables and provide covers made of non-combustible material preferably metal to protect the cables’ insulation from any physical damage.


Finding #: E- 4

Generator battery placed beside generator.


Finding: Generator battery placed on wet floor and wires terminating from battery are not covered.

Recommendation: Generator Battery must be placed on the acid proof battery stand and wires connecting point should be covered to prevent the risk of short circuit.


Finding #: E- 5

MCCB fixed on wall.

Category: SWITCH BOARD & PANELS

Finding: MCCB is not protected by covering/panel board.

Recommendation: Protective devices should be encased in metal casing made of 20 SWG thickness metal sheets.



Finding #: E- 6

Generator room.


Finding: Oil stored in generator room beside generator.

Recommendation: Remove diesel and other oil barrels from generator room. Inflammable items (may help spreading fire) stored near generator room must be removed.


Finding #: E- 7

Measuring earth loop resistance.

Category:

Finding: High earth loop impedance measured.

Recommendation: Check for loose earthing-connection and take necessary action accordingly.


Finding #: E- 8

Substation room.

Category:

Finding: Materials and equipments are stored in electrical room and near panel

Recommendation: Electrical room must not be used for storing/keeping items that are not associated with the operation and maintenance of the panel. Inflammable items (may help spreading fire) stored near panel(s) must be removed.



Finding #: E- 9

Cables inside panel board.


Finding: Excessive lint deposit in Panel.

Recommendation: Disconnect the panel form power source and clean the interior of the panel regularly and seal the openings to protect ingress of lint and dusts .Provide covers if any additional gap remains after installing cable glands.


Finding #: E- 10

Electrical substation room.

Category:

Finding:

Substation room is not protected and separated

Recommendation: Sub-station room must be separated from other section by a barrier walls. The walls must be fire resistant and should have height up to the ceiling. The wall should have the provision for necessary ventilation and fire rated door on required side.


Finding #: E- 11

PVC cables entering to panel base plate.

Category: CABLE & CABLE SUPPORTS

Finding: Flexible PVC conduits entering to panel base plate are not supported.

Recommendation: Use covered cable duct/ladder to support the cable at bottom of the panel. Flexible conduit must not be used for long point wiring (except for special wirings).Use industrial graded flexible pipes instead of using normal flexible pipes (if required).



Finding #: E- 12

Panel board.


Finding: Panel doors not connected with earth bond.

Recommendation: Provide earth connection for body and doors of metallic distribution boards using green cables preferably braid so that the metallic door remains at zero potential all the time.


Finding #: E- 13

MCCBs inside panel.


Finding: Barrier/separators between different phases are not installed.

Recommendation: Provide phase separators between poles of MCCB made of noncombustible materials preferably use rubber having enough dielectric strength to insulate phases from each other.


Finding #: E- 14

Cables joint in MCCB.


Finding: Multiple cables terminating to MCCB in panel.

Recommendation: Multiple cables connecting at a MCCB terminal must be removed. Individual circuit breaker must used for each load according to the respective cable-size.



Finding #: E- 15

Cables joint in bus bar.


Finding: Multiple cables connected at a terminal of the bus bar.

Recommendation: Terminate each cable proving individual lug according to the cable size. Multiple cables shall not be terminated on a single point of the bus-bar.


Finding #: E- 16

Panel base plate.


Finding: Gland holes in cable base plates left open.

Recommendation: Provide cable gland at the base plate of panels 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.


Finding #: E- 17

Panel top plate.


Finding: Openings in the panel top cover plate.

Recommendation: Provide cable gland at the base plate of panels 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.



Finding #: E- 18

Sewing floor.


Finding: Cable duct’s height is not at minimum safety clearance level.

Recommendation:

The height of cable duct must be considered at minimum safety level so that workers can work there easily without touching it.


Finding #: E-19

Cable duct fixed to ceiling over sewing floor.


Finding: Open cable ducts used for cable support.

Recommendation: Cable must be arranged and latched properly on the cable tray. Provide cover made of non-combustible material preferably metallic sheet to protect the cables’ insulation from physical damage as well as prevent the ingress of debris, dust and lint.


Finding #: E- 20

Switch board fixed on aluminum channel.


Finding: Broken or damaged switch fittings mounted on the wiring duct.

Recommendation: Broken/Damage switch fitting or power receptacles must be replaced with new one.
