Safety Procedures

  •  (1) All testing or work performed on electrical equipment must be performed by a person in charge or an employee under the direct supervision of a person in charge.

  • (2) Before authorizing a person to test or perform work on electrical equipment, the employer must ensure that a work permit referred to in section 166 has been obtained.

  • (3) If there is a possibility that the person in charge or the employee may receive a hazardous electrical shock during the performance of their testing or work,

    • (a) the person in charge or the employee must use insulated protection equipment and tools that will protect them from injury; and

    • (b) the employee must be trained and instructed in the use of the insulated protection equipment and tools.

  • (4) Subject to subsection (5), if an employee is working on or near electrical equipment that is live or may become live, the electrical equipment must be guarded.

  • (5) If it is not practicable for the electrical equipment to be guarded, the employer must take measures to protect the employee from injury by insulating the equipment from the employee or the employee from ground.

Safety Watcher

  •  (1) If an employee is working on or near live electrical equipment and, because of the nature of the work or the condition or location of the work place, it is necessary for the safety of the employee that the work be observed by a person not engaged in the work, the employer must appoint a safety watcher

    • (a) to warn all employees in the work place of the hazard; and

    • (b) to ensure that all safety precautions and procedures are complied with.

  • (2) Safety watchers must be

    • (a) informed of their duties as safety watchers and of the hazard involved in the work;

    • (b) trained and instructed in the procedures to follow in the event of an emergency;

    • (c) authorized to stop immediately any part of the work that they consider dangerous; and

    • (d) free of any other duties that might interfere with their duties as safety watchers.

  • (3) For the purposes of subsection (1), employers may appoint themselves as safety watchers.

Coordination of Work

 If an employee is working on or in connection with electrical equipment, that employee and every other person who is so working, including every safety watcher, must be fully informed by the employer with respect to the safe coordination of their work.

Switches and Control Devices

  •  (1) Every control device must be designed and located so as to permit quick and safe operation at all times.

  • (2) The path of access to every electrical switch, control device or meter must be free from obstruction.

  • (3) If an electrical switch or other control device controlling the supply of electrical energy to electrical equipment is operated only by a person authorized to do so by the employer, the switch or control device must be fitted with a locking device that only the authorized person can activate.

  • (4) Control switches for all electrically operated machinery must be clearly marked to indicate the switch positions.

Defective Electrical Equipment

 Defective electrical equipment must be disconnected from its power source by a means other than the control switch and notices must be placed on the equipment and at the control switch to indicate that the equipment is defective.

Electrical Fuses

  •  (1) Electrical fuses must be of the correct ampere rating and fault capacity rating for the circuit in which they are installed.

  • (2) An employee must not replace missing or burnt-out fuses unless authorized to do so by a person in charge.

Power Supply Cables

  •  (1) Power supply cables for portable electrical equipment must be placed clear of areas used for vehicles unless the cables are protected by guards.

  • (2) A three-wire power supply cable on electrical equipment or appliances must not be altered or changed for the purpose of connecting the equipment or appliances to a two-wire power supply.

Grounded Electrical Equipment

 Grounded electrical equipment and appliances must be used only when connected to a matching grounded electrical outlet receptacle.

Additional Requirement for the Issuance of a Work Permit

 In addition to the requirements set out in section 168, before an employer issues a work permit for electrical equipment under section 166, the employer must provide a guarantee of isolation in respect of each source of electrical energy.

Guarantees of Isolation of Electrical Equipment

  •  (1) An employee must not give or receive a guarantee of isolation for electrical equipment unless they are authorized in writing by their employer to give or receive a guarantee of isolation.

  • (2) No more than one employee is to give a guarantee of isolation for a piece of electrical equipment for a given period.

  • (3) Before an employer issues a work permit, the person in charge must receive from the guarantor

    • (a) a written guarantee of isolation; or

    • (b) if owing to an emergency it is not practicable for the person in charge to receive a written guarantee of isolation, a non-written guarantee of isolation.

  • (4) The written guarantee of isolation referred to in paragraph (3)(a) must be signed by the guarantor and by the person in charge and must contain the following information:

    • (a) the date and hour when the guarantee of isolation is given to the person in charge;

    • (b) the date and hour when the electrical equipment will become isolated;

    • (c) the date and hour when the isolation will be terminated, if known;

    • (d) the procedures by which isolation is assured;

    • (e) the name of the guarantor and the person in charge; and

    • (f) a statement as to whether live tests are to be performed.

  • (6) A written record must contain the information referred to in subsection (4).

  • (7) Every written guarantee of isolation and every written record must be

    • (a) kept by the person in charge and made readily available for examination by the employee performing the work or live test until the work or live test is completed;
