Indiana Code - Labor and Safety - Title 22, Section 22-10-10-6

Circuit breaking devices; switchboards; lights

Sec. 6. (a) Automatic circuit-breaking devices or fuses of the
correct type and capacity shall be installed so as to protect all electric
equipment and power circuits against excessive overload. Wires or
other conducting materials shall not be used as a substitute for
properly designed fuses, and circuit-breaking devices shall be
maintained in good operating condition.
(b) Operating controls, such as switches, starters, and switch
buttons, shall be so installed that they are readily accessible and can
be operated without danger of contact with moving or live parts. On
stationary equipment provision shall be made for locking starting
equipment in the "off" position to prevent accidental application of
power.
(c) Disconnecting switches shall be installed underground in all
main power circuits within five hundred (500) feet of the bottoms of
shafts and boreholes and at other places where main power circuits
enter the mine.
(d) Electric equipment and circuits shall be provided with
switches or other controls of safe design, construction, and
installation.
(e) Dry wooden platforms, insulating mats, or other electrically
nonconductive material shall be kept in place at each switchboard,
power control switch, and at stationary machinery where shock
hazards exist.
(f) Resistors or rheostats shall be installed in such a manner as not
to create a fire hazard and shall be guarded adequately against
personal contact.
(g) When not in use, power circuits underground shall be
deenergized on idle days and idle shifts.
(h) Electric parts, such as switches, circuit breakers, rheostats,
relays, and fuses, shall be installed on switchboards or mounted on
incombustible bases of slate or equivalent insulating material.
(i) Switchboards installed after March 8, 1955, shall be located so
that ample room will be provided between the switchboard and
passageways or lanes of travel and shall have an entrance at each end
to permit authorized persons to inspect, adjust, or repair apparatus
back of the board. Switchboards shall have the entrance to the rear
guarded against entrance of unauthorized persons, unless in a
building that is kept locked.
(j) Switchboards shall be well lighted for switch operations in the
front and for repair and maintenance in the rear.
(k) Rooms housing switchboards shall not be used for the storage
of combustible materials and shall be kept free of debris and refuse.
(l) Suitable danger signs shall be posted conspicuously at all
high-potential switchboard installations.
