I. Safety Retaining Devices.

(1) Safety retainers shall be provided, where possible, on tubs, cars, chairs, seats, gondolas, or other carriers that depend on a single means of attachment or support.

(2) Safety retainers shall be designed and installed to prevent a carrier from being catapulted if it becomes disengaged from its support or attachment.

J. Restraining and Containing Devices.

(1) A restraining or containing device, or a combination of the two, shall be provided on tubs, cars, chairs, seats, gondolas, or other carriers if:

(a) Forces resulting from operation, mechanical malfunction, or both, may unseat or dislodge a rider;

(b) Inadvertent movement of a rider may cause injury to the rider or another rider; or

(c) The speed of the amusement attraction may present a hazard to a rider.

(2) A restraining or containing device shall be designed, constructed, installed, and maintained to withstand the intended forces produced by the amusement attraction and the reasonably foreseeable actions of the rider.

(3) Anchorage for a restraining or containing device shall have strength at least equal to the strength of the device.

(4) A restraining or containing device:

(a) Shall provide safe support for riders;

(b) Shall be designed to prevent inadvertent release by a rider or by accidental means while the amusement attraction is in motion; and

(c) May not pose a hazard in itself.

K. Speeding and Overloading.

(1) An owner may not permit an amusement attraction to be:

(a) Loaded beyond its rated capacity; or

(b) Operated at an unsafe speed or at any speed other than that prescribed by the manufacturer's specifications.

(2) Speed-Limiting Device. If the amusement attraction is capable of exceeding the maximum speed, then a speed-limiting device shall be installed and functional to ensure that the amusement attraction does not exceed the maximum prescribed speed.

L. Brake System.

(1) The owner shall ensure that a braking system is utilized if coasting renders the operation dangerous:

(a) During the period the amusement attraction is being loaded or unloaded;

(b) In the case of power failure; or

(c) In any other situation.

(2) If the failure of the braking device results in an unsafe condition, the braking device shall be fail-safe.

(3) If cars or other components of an amusement attraction may collide and cause personal injuries on failure of normal controls, an emergency system sufficient to prevent these collisions shall be provided.

(4) An amusement attraction using inclined tracks, designed to operate in only one direction and having a lift hill with a vertical height exceeding 15 feet, shall have an automatic antirollback device sufficient to prevent rider-carrying units from moving backward if the propelling mechanism fails.

M. Internal Combustion Power Sources.

(1) Internal combustion power sources shall be:

(a) Of adequate type, design, and capacity to accommodate the design load;

(b) Located to permit proper maintenance; and

(c) Protected by guards, fencing, or an enclosure to prevent exposure to hazards and to secure the equipment.
