Motion Restriction And Other Specific Hazard Control Measures

(1) Emergency Brakes and Devices. If upon failure of normal stopping controls, collisions may reasonably be expected to occur. Amusement device conveyance vehicles shall be provided with emergency brakes or other equally effective emergency stopping controls. Low speed vehicles designed for controlled collisions do not require emergency stopping controls. (2) Anti-Rollback Controls. Each amusement device with a passenger conveyance vehicle that traverses an inclined track shall be provided with automatic anti-rollback controls unless such controls would conflict with the manufacturer’s recommendations. (3) Speed Limiting Devices and Systems. Each amusement device capable of exceeding its maximum design operating speed shall be provided with a speed limiting device or system to ensure that the amusement device cannot exceed that speed at any time while in operation. (4) Mechanical Governors. If a mechanical governor with an adjustable setting is used as a speed limiting device, the adjusting mechanism shall be sealed so that the speed setting cannot be changed without breaking the seal. If the seal is broken, the amusement device shall not be operated and the speed setting shall be readjusted and resealed according to the manufacturer’s specifications. (5) Other Speed Limiting Devices or Systems. If a speed limiting device or system other than a mechanical governor is used to control the maximum speed of an amusement device, the device or system shall include safeguards to prevent the device operator from being able to alter the maximum speed setting. (6) Signal Systems. (a) Signal systems shall be used and shall be adequate to do the following: ELEVATORS, DUMBWAITERS, ESCALATORS, AERIAL PASSENGER CHAPTER 0800-03-04 TRAMWAYS, MOVING WALKS, AND AMUSEMENT DEVICES 1. Control the dispatching of amusement devices as necessary to prevent collision due to any failure of the amusement device or amusement device unit to clear a stopping point. 2. Control the operation of the amusement device so that neither starting nor stopping the amusement device results in an unsafe condition. In the case of starting the amusement device, the signal system shall require that, before the start signal is given, there is confirmation that all patrons are safely secured within the amusement device and all other persons are a safe distance from the amusement device. (i) Exception: A signal system is not required if the amusement device is controlled by a single device operator who can clearly observe all phases of operation of the amusement device. (7) All signal systems shall be tested at least once each day prior to the initial operation of the amusement device. No amusement device shall be operated if the signal system is not functioning properly. (8) A written explanation of the use and testing of the signal system for each amusement device having a signal system shall be available at the device operator’s stations. (9) Protection from Hazardous Surfaces and Moving Parts. (a) Surfaces of amusement devices with which a patron may come in contact shall be free from sharp, rough, or splintered surfaces, edges and corners, and from unguarded or unprotected protruding studs, bolts, screws, and other projections. Surfaces that a patron may forcibly contact while in motion shall be adequately padded or otherwise designed and maintained to protect against injury. (10) All moving parts shall be sufficiently guarded to protect against injury. (11) Patron Retention, Restraint, and Support. (a) All tubs, cars, chairs, seats, gondolas, and other carriers shall be equipped as necessary to protect against injury with amusement devices that retain, restrain, or support the patron during all phases of the amusement device movement. All fastenings shall be of a type that cannot be released inadvertently or by accidental means. (b) All belts, bars, fastenings, anchorages, footrests, and other equipment or devices intended for the protection of patrons while they are on amusement devices shall be of adequate design and maintained to perform their intended functions. (12) Accessing and Exiting Amusement Devices. (a) All steps, ramps and walkways inside the site of the amusement device used for accessing and exiting the amusement device shall be of adequate design and maintained to perform their intended function. (13) Operation and Control of Amusement Devices. (a) All amusement devices shall be operated by authorized persons. All authorized persons shall be within immediate reach of the operating controls, even if automatic devices are used to control the time cycle of the amusement device. ELEVATORS, DUMBWAITERS, ESCALATORS, AERIAL PASSENGER CHAPTER 0800-03-04 TRAMWAYS, MOVING WALKS, AND AMUSEMENT DEVICES (b) All amusement devices shall have a stop switch within immediate reach of the authorized person at all times while the amusement device is in operation. (c) Each electrically driven amusement device shall have a disconnect switch within reach of the authorized person for use in case of emergency. In lieu of this disconnect switch, a stopping device that must be manually reset may be used. (d) No amusement device with a stop device or disconnect switch shall be capable of starting immediately upon reset of that device. (e) Equipment rooms, machinery rooms, and all other areas unsafe for access by unauthorized persons shall be locked, fenced or barricaded, and have signs posted to forbid unauthorized access. (f) Electrically energized overhead screens used to power amusement devices shall be free of holes that are not part of the design.
