Hawaii Administrative Rules › Title 12 - DEPARTMENT OF LABOR AND INDUSTRIAL RELATIONS › Subtitle 8 - HAWAII OCCUPATIONAL SAFETY AND HEALTH DIVISION › Part 11 - ELEVATORS AND RELATED SYSTEMS › Chapter 250 - AMUSEMENT RIDES › Section 12-250-10 - Electrical safety requirements

Current through June,
				  2024
(a) All electrical
				  wiring, equipment, and apparatus used for amusement rides or for lighting shall
				  be properly and legally installed, operated, and maintained, as required by
				  NFPA 70 and local ordinances.
(b)
				  No employee shall be suffered or permitted to work in such proximity to any
				  part of electrical power circuits that the employee may contact the same in the
				  course of the work unless protected against shock by de-energizing the circuit,
				  grounding it, or guarding it by effective insulation. If protection is supplied
				  by de-energizing the circuit, the switch controlling the circuit shall be
				  locked out to prevent inadvertent closing.
(c) The outlets of electric power lines
				  carrying more than 120 volts shall be clearly marked to show their
				  voltage.
(d) All electric
				  transformer sub-stations shall be properly enclosed and proper warning signs
				  shall be posted.
(e) Electrical
				  apparatus and wiring located outdoors shall be of such quality and so
				  constructed or protected that exposure to weather will not interfere with its
				  normal operation or endanger life or property.
(f) Elevated power lines crossing access or
				  other roads within the grounds of the carnival, circus, fair, amusement parks,
				  or other areas where the amusement rides are located shall be so suspended as
				  to provide minimum vertical clearance of 12 feet (3.6 m) from the road surface
				  and minimum horizontal clearance of 3 feet (90 cm) from each side of the normal
				  passage space of vehicles.
(g)
				  Wiring laid on or under surfaces traversed by vehicular or pedestrian traffic
				  shall be adequately protected against wear and abrasion. Buried cables shall be
				  Type UF as required by Article 339 of NFPA 70.
(h) Temporary electric wiring if suspended
				  shall be so supported that its protective insulation will not be
				  damaged.
(i) All electrical
				  installations shall be properly grounded. All electrical cords shall be of the
				  heavy duty type and shall contain an identifying grounding conductor in
				  addition to the current-carrying conductors. The size of grounding conductor
				  shall comply with Table 250-94 of NFPA 70.
(j) Bare wires and other uninsulated
				  current-carrying parts shall be guarded against accidental contact by means of
				  proper location or by a fence or other barrier.
(k) Conductors shall be provided with
				  over-current protective devices according to load and current-carrying
				  capacity. No such device shall be installed on neutral or grounding
				  conductors.
(l) Where electrical
				  power is supplied for an amusement ride by a privately operated generating
				  system, the generator and all equipment shall be properly grounded if the
				  system incorporates a ground.
(m)
				  All receptacles and attachment caps shall be of the grounding type.
(n) Each electrically powered amusement ride
				  shall be effectively grounded. The grounding shall be made effective as to all
				  non-current-carrying metal parts which may become energized and which are
				  exposed to contact by any person.
(o) Each electrically operated amusement ride
				  not designed to be controlled directly by the passenger shall be provided with
				  a disconnect power switch placed within easy reach of the operator.
