17.B.02 Flight and apron conveyors must be "jogged" or hand run through at least one complete revolution at installation to check design clearances prior to running under automatic power.
17.B.03 A conveyor that could cause injury when started must not be started until all personnel in the area are alerted by a signal or by a designated person that the conveyor is about to start.
17.B.04 When a conveyor that could cause injury when started is automatically controlled or must be controlled from a remote location, an audible warning device must be provided. The device must be clearly audible at all points along the conveyor where personnel may be present.

These warnings signs must be provided along the conveyor at areas that are not guarded or protected by their location.
