they pass into or out of electrical compartments;

10. Power wires and cables which present a fire hazard shall be

well installed on acceptable insulators;

11. Where metallic tools or equipment can come in contact with

bare power lines, the lines shall be guarded or de-energized;

12. Telephone and low potential electric signal wires shall be

protected from contacting energized power lines;

13. High potential transmission cables shall be covered,

insulated or placed according to acceptable electrical codes to

prevent contact with low potential circuits;

14. The potential on bare signal wires accessible to personal

contact should not exceed thirty (30) volts;

15. Splices in power cables, including ground conductor, where

provided, shall be:

a. mechanically strong with adequate electrical

conductivity,

b. effectively insulated and sealed to exclude

moisture, and

c. provided with mechanical protection and

electrical conductivity as near as possible to that of the original;

16. Shovel trailing cables shall not be moved with the shovel

dipper unless cable slings or sleds are used;

17. Energized high potential cables shall be handled with

insulated hooks or tongs;

18. Electrical equipment shall be de-energized before work is

done on such equipment. Switches shall be locked out and suitable

warning signs posted by the individuals who are to do the work;

locks shall be removed only by authorized persons;

19. Power circuits shall be de-energized before work is done

on such circuits unless hot line tools are used. Switches shall be

locked out and suitable warning signs posted by the individuals who

are to do the work; locks shall be removed only by authorized

persons;

20. Principal power switches shall be labeled to show which

units they control;

21. At least three (3) feet of clearance shall be provided

around all parts of stationary electric equipment or switch gear

where access or travel is necessary;

22. Dry wooden platforms, insulating mats or other

electrically nonconductive material shall be kept in place at all

switchboards and power control switches where shock hazards exist.

However, metal plates on which a person normally would stand, plates

which are kept at the same potential as the grounded metal

noncurrent carrying parts of the power switches to be operated may

be used;

23. Suitable danger signs shall be posted at all major

electrical installations;

24. Areas containing major electrical installations shall be

entered only by authorized personnel;

25. Electrical connections and resistor grids that are

difficult or impractical to insulate shall be guarded unless

protection is provided by location;

26. Reverse-current protection shall be provided at storage

battery charging stations;
shall be posted at all major

electrical installations;

24. Areas containing major electrical installations shall be

entered only by authorized personnel;

25. Electrical connections and resistor grids that are

difficult or impractical to insulate shall be guarded unless

protection is provided by location;

26. Reverse-current protection shall be provided at storage

battery charging stations;

27. All metal enclosing or encasing electrical circuits shall

be grounded or provided with equivalent protection. This

requirement does not apply to battery-operated equipment;

28. Metal fencing and metal buildings enclosing transformers

and switch gear shall be grounded;

29. Frame grounding or equivalent protection shall be provided

for mobile equipment powered through trailing cables;

30. Continuity and resistance of grounding systems shall be

tested immediately after installation;

31. Electric equipment and wiring shall be inspected by a

certified person as often as necessary to assure safe operating

conditions;

32. When a potentially dangerous condition is found it shall

be corrected before equipment or wiring is energized;

33. Inspection and cover plates on electrical equipment shall

be kept in place at all times except during testing or repairs;

34. Circuits shall be de-energized before fuses are removed or

replaced;

35. Fuse tongs or hot line tools shall be used when fuses are

removed or replaced in medium or high voltage circuits;

36. Trailing cables shall be clamped to machines in a manner

to protect the cables from damage and to prevent strain on the

electrical connections;

37. Surplus trailing cables to shovels, cranes and similar

equipment shall be stored in cable boots or on reels mounted on the

equipment or otherwise protected from mechanical damage;

38. Operating controls shall be installed so that they can be

operated without danger of contact with energized conductors;

39. Equipment with booms or masts which are not properly

protected shall not be operated where the booms or masts can come

within ten (10) feet of an energized overhead power line;

40. Overhead high potential power lines shall be installed as

specified by the National Electrical Safety Code;

41. When equipment must be moved under energized power lines

and the clearance is less than ten (10) feet, the power lines shall

be de-energized or other precautions shall be taken;

42. Guy wires from poles supporting high voltage transmission

lines shall be securely connected to the system ground or be

provided with insulators installed near the pole end;

43. Telegraph, telephone or signal wires shall not be

installed on the same crossarm with power conductors. When carried

on poles supporting power lines, they shall be installed as

specified by the National Electrical Safety Code;

44. Transformers shall be totally enclosed or shall be placed

at least fifteen (15) feet above the ground, twenty (20) feet above

driveways and haulage ways, or installed in a transformer house, or
