Current through Register Vol. 56, No. 14, July 15, 2024
(a) All electrical equipment shall be rated in accordance with current standards of the American Institute of Electrical Engineers and shall be operated within such rated capacity. Such rating shall be legibly posted on the equipment. The plate bearing such information shall indicate whether the rating is for continuous or intermittent service and shall be in accordance with the name plate requirements of the American Institute of Electrical Engineers.
(b) All electrical equipment, machinery and apparatus shall be installed with sufficient space and in a manner to be readily and safely accessible to provide for the safe and efficient operation, maintenance and manipulation of such equipment, machinery and apparatus.
(c) No person, unless authorized by the employer, shall be permitted to operate, install or maintain any electrical circuits, machinery or equipment. Every person so authorized shall be thoroughly familiar with the proper methods of operation and maintenance of such circuits, equipment and machinery.
(d) All electrical circuits, machinery and equipment shall be in charge of a worker fitted for the job by ability, training and experience.
(e) Employees regularly working on electrical equipment shall be thoroughly instructed in methods of first aid and fire extinguishment.
(f) Any defective equipment shall be replaced at once upon discovery or report of same.
(g) Instructions in administering resuscitation after electric shock and disengaging a person from live conductors shall be conspicuously posted at strategic locations.
(h) All stationary machinery, controls, switches, transformers and rheostats shall be so located or so protected as to prevent damage thereto.
(i) All metallic frames, casings and coverings of motors, generators, switchboards and other electrical equipment that can become "alive" through failure of insulation or by contact with energized parts, shall be grounded.
(j) All metallic coverings and armor of cables and of conduit shall be grounded and electrically continuous, so as to afford a conductor path for the ground circuit.
(k) Before any repair work is started on any power circuit or electrical equipment, the power must be disconnected, and the switches shall be locked open while repairs are made on machinery or other equipment. Work on electric circuits and apparatus with the current on shall only be done if conditions made it absolutely necessary in which case adequate precautions shall be taken. Precautions for working on live circuits should include insulated foot supports, such as rubber boots, dry wooden ladders or insulated platforms, and approved rubber gloves, approved shields and blankets for covering live parts and grounds.
(
l
) After repairs are made, control switches shall not be turned to "On" position until it has been determined there will be no fire hazard nor the hazard of electric shock.
(m) Wires, pieces of wire, or other conducting material shall not be used as a substitute for properly designed fuses.
(n) Dry wooden platforms, insulating mats, or other electrically nonconductive material shall be kept in place at each switchboard, and power control switch where shock hazards exist.
(
o
) Fuses or equivalent protective devices of the correct type and capacity shall be installed on all electrical equipment to be protected against excessive overload.
(p) All electrical appliances, machines and conductors shall be large enough for the work required of them.
(q) Provisions should be made so that individual circuits can be checked periodically for ground failures.
(r) Surface power poles supported by guy wires shall have insulators on the guy wires at the pole end. Such guy wires shall not, under any circumstances, be used as a part of the grounding circuit.
