APPENDIX D

FIRST AID FOR ELECTRIC SHOCK

What to do:

1.

Switch off the main switch.

2.

Break the contact between electrical source and patient using dry non-conductive

object like wooden stick.

3. Call for help.

4.

If breathing and heartbeat has stopped begin Cardio pulmonary resuscitation (C.P.R)

5.

If breathing, but unconscious : Recovery Position

6.

Treat any Burns

7. Treat for Shock

8.

Secure the area by suitable barriers like caution tape to prevent others contacting live

apparatus.

Do not:

1. Touch the patient directly.

2.

Panic or go near the area if high voltage electricity is suspected.





CPR IN THREE SIMPLE STEPS

Check the Scene

Make sure it is safe for you to help. Don't become another victim

Check the Victim

Tap and shout to get response

Call for Help

If there is no response, Call 9999, or tell

someone to call.

If you are alone with an adult, call first

then return to the victim

AirwayTilt head back, lift chin up to open airway. Listen for breathing.

BREATHING

If not breathing, pinch nose and cover the

mouth with yours and blow until you see

the chest rise. Give 2 breaths. Each breath

should take 1 second. If chest doesn't rise,

open airway again.





Circulation

If the victim is still not breathing normally,

coughing or moving, begin chest

compressions. Pump the chest 30 times.

Place the heel of one hand in the center of

the chest and your other hand on top of it.Push down on the chest 1½ to 2 inches 30

times right between the nipples. Pump at

the rate of 100/minute, faster than once

per second (16 in 10 seconds).

Repeat A - B - CUntil help arrives or the victim begins breathing.

If there are two rescuers, one does the breathing and one does the compressions - CPR

steps and ratios remain the same.





Recovery

If breathing and pulse OK, recovery position

ensures the prevention of tongue falling back and

blocking the airway.

Place the patient on their back.

Lift the chin to ensure the Lift the chin to ensure

the airway is open. Patient's arm on your side

should be positioned so as to make a right angle

with his body, with elbow bent and palm facing

out.

Patient's other arm on opposite side should be

placed across the chest, with back of their hand

against the cheek on your side of the patient.

Pull up the patient's knee point (side away from

you) as it bends with the foot flat on the ground.

Roll over the patient in this position towards your

side.

By tilting the patient's head back ensure that the

airway is open. The uppermost leg should be

adjusted in such a way that the hip and knee are

at right angles.

In case of a fall from height, do not move the patient

if a spinal injury is suspected.

Just remember to save a life!





Burns

1.

The affected area should be immediately kept under cold running water for 10 mins.

Helps to dissipate the localized high heat and reduces further burns by cooling off

the skin and tissues.

2.

Remove clothing, watch and other jewelry

from the affected area.

3. Burnt area should be covered with sterile,

non-fluffy dressing / cling film

Do not :

1.

Burst skin blisters.

2. Remove skin.

3. Apply creams, lotions on the burns.

4. Make the patient move unless you

need to for treatment.

5. Waste time, as burns can result into

death.

6. Feed by mouth - liquid or solids.

Shock (This is not same as electric shock)

Develop when oxygen delivery to the tissues is inadequate to meet the metabolic

requirements of the tissues. It can be caused by Trauma, Fear, and Loss of Body Fluids due

to burns.

Symptoms: Sweating, Unconscious, Confused and anxiety, Rapid breathing, Rapid and weak

pulse, Thirst, Nausea and vomiting, pale appearance

1. Reassure, loosen any tight clothing, and keep area warm and airy.

2. If the cause can be removed such as - bleeding / burns.

3.

If no fracture make the patient lies down and raise and support his legs.4. If unconscious place in recovery position.

5. Monitor and the casualty.

6. Do not:

1. Feed the patient by mouth in spite of thirst.

2. Make the patient stand up or walk or run.

3. Allow the patient to smoke

GUIDANCE FOR ACTIVITIES IN THE VICINITY OF OVERHESD LINES

This guidance addresses:

Passage underneath overhead power lines

Small residential work sites in the vicinity of live overhead power lines

Industrial and large scale commercial work sites in the vicinity of live overhead power

lines

Excavation and other low level activity directly underneath overhead power lines

Safety clearances

Clearance Certificates

1 General Requirements

1.1 Passage Underneath Overhead Power Lines crossing roads, tracks or right of way.

1.1.1 Clear sign-posting (including maximum allowable height indication signs) and a suitable

type of goal post arrangement on either side of the overhead line at the entrance of

roads, tracks or right of way, wherever the line crosses the roads, tracks or right of way

shall be provided. The safety clearances between the cross bars and the lowest

conductor shall be in accordance with Section 1.3. Due to changes in road conditions

MJEC shall frequently updates the sign posts to reflect the actual goal post height.

1.1.2 Wood poles shall be used in the construction of safety barriers and goal posts. On sign

posted roads, goal posts shall be erected with a minimum horizontal distance from the

overhead power line of 75 metres. This enables vehicles which are too high and hit the

goal post, to stop safely before reaching the overhead line crossing.

1.1.3 The responsible person for the vehicle or other plant moving or working underneath the

power lines shall submit the clearance certificate not less than 48 hrs to allow enough

time for the Area AUTHORIZED ELRCTRICAL PERSON to conduct site visit if required.

1.1.4 When high loads, travels long distance and crosses overhead lines through a number of

locations, the mobilisation team (and prior to mobilisation ) shall conduct crossing

points survey and submit to the issuer of clearance certificate with following details:

Line tag

Pole number a crossing location

Voltage type

Height if applicable





Availability and integrity of goal posts

The Clarence certificate shall be issued at the location by an AUTHORISED ELECTRICAL

PERSON (AEP) who shall verify the survey with available records. For any mismatch a re-

survey is a must on mismatching location(s).

1.2 Work Underneath or close to Overhead Power Lines.

1.2.1 If work is to take place underneath or within 5 meters of a live overhead line, then the

safety clearances given in Section 2.3 shall be applied. Suitable means should be put in

place, where necessary, to ensure that safety clearances are maintained. This is

particularly important if cranes and jibs, or similar equipment are to be used.

1.2.1 If verbal instructions are not considered sufficient by the AUTHORISED ELECTRICAL

PERSON, then he shall issue a “LIMITATION OF ACCESS” to COMPETENT ELECTRICALPERSON (CEP) who shall remain at the work location and oversee the work activities. If

the CEP is not in charge of the work, then it shall be made clear to the person in charge

that the CEP is on site to enforce the safety precautions and the safety clearances called

for on the “LIMITATION OF ACCESS”. The CEP shall be given full authority to stop the

work if it is considered unsafe.

1.2.2 If the work, or passage of vehicles, is such that the safety clearances cannot be

reasonably maintained in practice and there is a danger of personnel, materials, or

vehicles infringing the safety clearances, then the overhead line shall be made dead,

isolated and earthed. In this case an ELECTRICAL PERMIT TO WORK (EPTW) shall be

issued to a CEP, who will remain onsite to ensure safety of personnel involved. It shall

be stated in the 'Work Description’ Section of EPTW that the High Voltage overhead line

has been made safe so that passage / work can take place near / under the earthed

conductors, but no work shall be carried out on the conductors themselves.

1.2.3 At all other sites subjected to passage underneath overhead power lines (e.g., access

roads to construction sites), goal posts and safety barriers shall be erected at an

absolute minimum horizontal distance of 6 meters from the overhead line to ensure

that mobile plant crosses under the overhead line via the goal posts (ref Figure 2).





1.3 Safety Clearances

1.3.1 The minimum vertical safety clearance to the lowest conductor of the overhead line,

beyond which no person or object can approach shall be:

33kV 1.2 meters

11kV 0.9 meters

1.3.2 The following factors shall be taken into account when deciding the safety clearances.

Has the ground level been raised in any way which could reduce the design

clearances of overhead line?

Check the area under the line for humps or bumps which could reduce safety

clearances.

1.4 Major Work Sites in the Vicinity of Live Overhead Lines

If major construction activity involving cranes, high loads and other heavy plant, is to

take place within 15 metres of a live overhead line, safety barriers shall be erected. The

absolute minimum horizontal distance of the safety barriers from the line should be 6

metres (ref Figure 1).

1.5 Major activity Directly Underneath Overhead Power Lines

1.5.1 If major construction activity involving earth moving and other heavy plant, is to take

place below live overhead line, where possible overhead power lines should be made

dead. If this is not practicable, then strict precautions shall be enforced whilst work is in

progress.

1.5.2 The safety precautions for such work shall be closely supervised by the Area Distribution

representative who shall ensure that a minimum vertical safety clearance of 3.5 meters

is maintained at all times. Figures 2 and 3 illustrate methods that can be adopted, using

goal posts and safety barriers, to assist in promoting safe working practices.

APPENDIX H

Safe Steps to be observed while executing switching program and issuing E PTW

1.

Switching Program must be prepared as specified in ESRs with all necessary info and tobe attached with updated single line diagram, then to be sent to DCC to get it checked

from RCP and then approved by LCP. AEP is to make sure that DCC has the final copy of

approved switching program

(After being reviewed by RCP, corrections made, signed by LCP)

2. AEP is required to keep the approved switching program document along with him on

site during work & inform RCP before starting the Switching program & during the

execution of the program and when restoring supply with all details.

3. As first step in executing the switching program, AEP is to Switch off and identify all

possible points of supply as per approved switching program.

4.

Once above is done, AEP is to Isolate, establish physical gap between live and deadpoints

5. After that, AEP is to TEST VOLTAGE to ensure the system (equipment) to be worked on is

dead & proved to be dead using proper voltage tester.

6. Then, AEP to APPLY Safety Padlock(Lock out all live systems and never assume)

7. Then, AEP to APPLY CN (Put caution notices at points of Isolation) lock & maintain key

safe.

8. Then, AEP to APPLY DN (put danger notices at nearby exposed live equipment), put

suitable barricade mean around nearby live equipment.

9. Then AEP to APPLY EARTH (Identify the points of Earthing and apply CMEs)

10.

Then, AEP to APPLY EN (Put Earthing notices at points of earth )

11.

AEP is to BREIF the CEP on the work to be done, make him aware of all isolation points,earthling, etc., and inform him where he needs to apply ‘AE’ if required….

12. Then AEP to ISSUE EPTW to CEP, & shall make sure that he has understood what has

been written in the permit. The permit needs to be written in clear writing with ink and

in capital letters.

13. The CEP shouldn’t allow his crew enter/attended restricted work area until the area/site

is made to be safe and EPTW is issued by AEP.

14.

CEP is to Receive EPTW and signs it after making sure that he understood its content

and conditions as specified.

15. CEP is to brief his crew on the work to be done and conduct tool box talk & must adhere

to EPTW and GPTW procedure.For emergency cases and outages toll box talk should be sufficient.

16. CEP is to Apply Additional Earth at dead points of work.

17. CEP has to supervise his crew during execution of the work and must observe that all

safety precautions are in place all times.

18. Once work is done, CEP is to Remove additional earth

19. CEP is to Clear EPTW and GPTW.

20. AEP is Cancel EPTW and GPTW and should inform RCP accordingly.





21. AEP is to Remove CME.

22. AEP is to De-isolate and remove CN & DN

23. AEP is to Switch on & confirm supply in three phases and secure the assets by checking

any relay indications and call RCP for any alarms pending for normal before leaving the

substation.

24.

AEP is to inform RCP of system coming back.25. AEP is to submit canceled EPTW & Switching program to RCP.

26. RCP is to archive EPTW, Switching Program, drawings for a year.

27. RCP is to review for any deviation done while executing the work and highlight any non-

conformances to HSSE department.

Note: AEP, CEP (and his crew) must wear the necessary PPE during executing the work. In case

of Racking out a CB, AEP must wear ARC-FLASH suit.

APPENDIX N

to work (GPTW ) ProceduresPermitGeneric

In line with MJEC HSSE policies and OHSAS 18001 requirement the generic PTW system was

developed as part of a safe working system that will enhance the adherence to the company

HSSE procedures and will provide a better control of hazards at work site.

The GPTW in itself will not make the work safer but adherence to its requirements will. The

GPTW is an official document consists of an application form, and other associated permits e.g.

EPTW, LOA, SFT, certificates e.g. excavation certificate and Job safety plan.

Any work to be conducted in and within MJEC network/assets has to be covered with GPTW.

GPTW Process

Any MJEC department or contractor want to do a work within MJEC network, assets , facility

etc. has to apply for GPTW.

who could be MJEC or contractor engineer. TheapplicantThe GPTW should be raised by

Applicant responsibility is to fill section A in GPTW, specifying the details of work location, dates

of execution, work description etc. Please refer to GPTW section A.

; he should write all the hazardsJOB SAFETY PLANMost importantly he should prepare the

associated with work along with HSSE controls. For details please refer to JOB SAFETY plan

form.

ResponsibleOnce the above is done, then applicant should bring the GPTW in person to MJEC

The MJEC Responsible Engineer, refer to him, as.PTW issuerGwho is referred to asEngineer

issuer should fill section B of the GPTW form. He should make sure that all information he

ticks/puts is correct according to the nature of work required to be done. He should make sure

that E-PTW is filled and approved, switching program and other forms and certificates are

JOB SAFETYreview with applicant theattached, filled and approved accordingly, He should





he should endorse the JOB SAFETYdiscuss with him the hazards and HSSE controls, then,PLAN

PLAN. He should retain the white copy of the GPTW form, while the blue color should be

handed over to the applicant and to be kept at the work site.

If the work is to be done in the MJEC network, assets and facilities, then normally the MJEC

Responsible Engineer, refer to him as issuer, is the area/zone distribution engineer.

In case if the applicant is not the one who will execute the work at site but his foreman , who is

of the GPTW applicant to make sure that his, then it is the responsibilityPTW holdercalled

PTW holder understood the work hazards and HSSE controls. He should discuss these in person

with him.

The permit holder (who can be the applicant himself or his foremen) should fill section C in

GPTW form, please refer to GPTW form.

The PTW holder should only sign once he knows the work to be done, the hazards associated

with work activities and HSSE controls. Then before work starts he should discuss the hazards

and HSSE controls with his work party. He should make sure that his work party understood

these. Then he can proceed on the work execution.

Once the work is complete or in case it is incomplete due to certain circumstances he should fill

in section D of the GPTW accordingly.

Then PTW holder or the applicant must submit the GPTW to MJEC Responsible Engineer (the

issuer) to fill in section E and cancel the GPTW accordingly.

System Archiving:

Once the GPTW is canceled the Responsible Engineer (issuer) should retain the GPTW for a

period of six months then the canceled GPTW can be disposed off.
