(Additional Provision Relating to Distribution System)

• The work shall be carried out under a suitable clearance.
• The employee in charge at each tower shall be provided with a green flag which fits the socket for that circuit on the tower on which work is to be carried out and shall place the green flag in position before allowing any man to ascend the tower.
• The conductors shall be efficiently connected to each by the Authorised Person or a Competent Person working under his direct supervision at the point of work unless they are to be broken, or let down for examination. During this time the conductors shall be earthed at the nearest tower on each side of the point of work where they are still secured in the clamps, but in no case shall the earths be more than six spans apart.
• When work is to be carried out on lines of all insulated construction and an earthing point is not provided at the point of work. The line shall also be earthed at the nearest line earthing point on either side of the point of work.

Where work similar to that covered under paragraph 12.5.1 is to be carried out on double circuit overhead lines with one of the circuits live, the provisions of paragraph 12.5.1 shall apply, and the following additional precautions shall be taken :-

• After placing in position the green flag, which shall fit the socket on the dead side of the tower and before any other employee is allowed access to the tower, the Authorised Person or the Competent Person working  under the direct supervision of the Authorised Person at the point of work shall climb the tower on the DEAD side, and shall efficiently connect to earth all three conductors on that side. He shall then affix red pennants to the Cross arms supporting the live conductors at the junction of these cross arms with the tower body. The conductors shall remain efficiently earthed, and the red pennants shall remain in position, throughout the progress of the work, and the earths and pennants shall be removed by the Authorised Person  or Competent Persons working under his direct supervision only after all other member of the working party have descended the tower on completion of the work. While affixing or removing earths and red pennants, the persons concerned shall be under observation by another employee at ground level.
• The Authorised Person in charge shall see that danger notices are fixed to make it clear to all concerned on which portion it is safe to work and shall issue to each person, who is to work on the poles or towers, an armlet or wristlet bearing the distinguishing number or symbol of the overhead line on which he is to work. The armlet of wristlet shall be worn by the person to whom it is issued during the whole period that he is engaged on the work. He shall not bring any part of his body or any working tool within the distance, specified under para : 12.4.11 above, or any live conductor. On the conclusion of the work, the armlets or wristlets shall be collected by the Authorised Person.
• Work on TEE-OFF tower shall only be carried out in the presence of a Senior Authorised Person and special care shall be taken at terminal and large angle towers.

• The work shall be carried out as per provisions of paragraphs 12.5.1 and 12.5.2
• Separate means or access to each individual circuit, as provided, shall be used for work on any circuit.
• Unless the clearances from the nearest point of work to the remaining live circuits are strictly in accordance with the provisions of paragraph Nos. 12.4.11 care shall be taken to provide screens as per provisions of paragraph 11.4.5.

• Work shall be carried out as per provisions of paragraphs 12.5.1 and 12.5.2.
• Both the circuits on the side of the tower on which work is to be carried out shall switched out, isolated and earthed.

• The work shall be carried out under a permit-to-work, sanction-for-test or self-protection guarantee.
• Before changing or replenishing oil in, or painting, the transformer all exposed live parts of the transformer shall be disconnected.
• While working on poles which have lightening arresters installed on them, the workmen shall avoid touching lightning arresters and the lightning arrester ground wires.
• Open flame shall not be brought near an open transformer.

• The new line shall be earthed and remain as such till the completion of the work.
• Unless the existing line is dead and earthed, every employee handling the new line shall use insulating gloves and boots or galoshes.
• No employee shall be on any cross arm on which the new line is to be erected while such a line a being pulled up.

• No employee shall climb above the anti-climbing device unless under observation by a safety man;
• No tool above 30.48 cm (12 inches) in length shall be taken up the tower;
• In so far as practicable, the work shall be carried out from within the body of the tower;
• No employee shall work in a manner that his access way or arms or any tool extend beyond the limitations fixed under paragraph 11.4.4 and 11.4.5 respectively.

• Every communication line supported on poles carrying high voltage or extra high voltage electric lines shall, for the purposes of working thereon, be deemed to be a high voltage electric line and every person working on such communication line shall take similar precautions to those provided under para 12.4:
• When working on the telephone lines supported on poles carrying medium and low voltage lines, the employees shall avoid contact with the supply line and grounded metal fixtures in the case of wood pole.
• Earths shall be installed on both sides of the point of work, when repairing a break in telephone lines.

• Telephone test sets shall not be used on circuits known to carry excessive voltages unless specially designed for this purpose.
• Operators for telephone systems shall stand on an insulated platform or rubber insulation mat while speaking to protect himself against leakage of induced voltage on communication equipment.
• The operator, while speaking, shall not touch any metal frame of the telephone equipment to avoid the risk of electric shock due to leakage or discharge of high induced voltage.
