A. Unless surface transformers are isolated by elevation (eight feet or moreabove the ground), they shall be enclosed in a transformer house orsurrounded by a suitable fence at least six feet high. If the enclosure orfence is of metal, it shall be grounded effectively. The gate or door to theenclosure shall be kept locked at all times, unless authorized persons arepresent.
B. Surface transformers containing flammable oil and installed where theypresent a fire hazard shall be provided with means to drain or to confine theoil in the event of rupture of the transformer casing.
C. Suitable danger signs shall be posted conspicuously at all transformerstations on the surface.
D. All transformer stations on the surface shall be kept free of nonessentialcombustible materials and refuse.
E. No electrical work shall be performed on low-voltage, medium-voltage, orhigh-voltage distribution circuits or equipment, except by a certified personor by a person trained to perform electrical work and to maintain electricalequipment under the direct supervision of a certified person. Allhigh-voltage circuits shall be grounded before repair work is performed.Disconnecting devices shall be locked out and suitably tagged by the personswho perform electrical or mechanical work on such circuits or equipmentconnected to the circuits, except that in cases where locking out is notpossible, such devices shall be opened and suitably tagged by such persons.Locks and tags shall be removed only by the persons who installed them or, ifsuch persons are unavailable, by certified persons authorized by the operatoror his agent. However, employees may, where necessary, repair energizedtrolley wires if they wear insulated shoes and lineman's gloves. This sectiondoes not prohibit certified electrical repairmen from making checks on ortroubleshooting energized circuits or the performance of repairs ormaintenance on equipment by authorized persons once the power is off and theequipment is blocked against motion, except where motion is necessary to makeadjustments.
