Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Devices
						Required.
Operating and safety devices shall be provided
						  conforming to the following requirements:
(1) Starting switches shall be of the
						key-operated, spring return-type and shall be located within sight of the
						exposed treadway.
(2) Emergency
						stop buttons or other types of manually operated switches having red buttons or
						handles shall be accessibly located at every entrance to and exit from a moving
						walk, and shall be protected against accidental operation. The operation of any
						of these buttons or switches shall interrupt the power to the driving machine
						and to the brake, where provided. It shall be impossible to start the driving
						machine by these buttons or switches.
(3) Where the driving machine is connected to
						the main drive shaft by a chain, and where a brake is located on that shaft
						when required by Section
						3091(n)(2), a
						device shall be provided which will cause the application by such brake if the
						drive chain parts.
(4) Moving walks
						required by Section
						3091(n)(2) to be
						equipped with a brake, or which are driven by a direct current motor, shall be
						provided with a speed governor which will cause the interruption of power to
						the driving machine and to the brake, where provided, should the speed of the
						treadway exceed a predetermined value, which shall be not more than 40 percent
						above the maximum designed treadway speed.
EXCEPTION:
1.
						Moving walks driven by low slip-alternating current induction motors directly
						connected to the driving machine do not require speed governors.
2. Moving walks driven by low
						slip-alternating current induction motors connected to the driving machine by
						belts or chains, where a device is provided which will cause interruption of
						power to the motor and apply the brake should the belts lose driving tension or
						should the belts or chains break.
(5) A device shall be provided which will
						cause interruption of power to the driving machine and to the brake, where
						provided, if the connecting means between pallets break.
(6) Where a device is required to interrupt
						power, such interruption shall be not subject to intentional delay. The use of
						a supplemental and independent device with or without intentional delay is
						permissible.
(7) Each space
						containing moving parts, where a means of access is provided, shall be equipped
						with a stop switch located adjacent to the access door or panel. The stop
						switches shall:
(A) Be of the manually opened
						and closed type.
(B) Be
						conspicuously and permanently marked, "STOP."
(C) Be positively opened mechanically and
						their opening shall not be solely dependent on springs.
(D) When opened, cause electric power to be
						removed from the moving walk driving machine motor and
						brake.
