Section 5001 - Signals - General Requirements(a) A signal person shall be provided when the point of operation is not in full and direct view of the operator unless a signaling or control device is provided for safe direction of the operator.(1) Supplemental requirements for mobile cranes in construction. A signal person shall be provided if:(A) when the equipment is traveling, the view in the direction of travel is obstructed.(B) due to site specific safety concerns, either the operator or the person handling the load determines that it is necessary.(b) Only qualified persons shall be permitted to give signals. EXCEPTION: A stop signal may be given by any person.
(c) Types of signals. Signals to operators shall be by hand, voice, or audible.(d) Hand Signals. (1) A uniform signal system shall be used on all operations and if hand signals are used, they shall be clearly understood by the operator. (NOTE: For recommended hand signals, see Plate I.) EXCEPTION: Where an operation or use of an attachment is not covered in the Standard Method, non-standard hand signals may be used in accordance with subsection (d)(2).
(2) Non-standard hand signals. When using non-standard hand signals, the signal person, operator, and lift director (where there is one) shall contact each other prior to the operation and agree on the non-standard hand signals that will be used.(e) There shall be conspicuously posted in the vicinity of the hoisting operations, a legible chart depicting and explaining the system of signals used.(f) Suitability. The signals used (hand, voice, or audible), and means of transmitting the signals to the operator (such as direct line of sight, video, radio, etc.), shall be appropriate for the site conditions.(g) During operations requiring signals, the ability to transmit signals between the operator and signal person shall be maintained. If that ability is interrupted at any time, the operator shall safely stop operations requiring signals until it is reestablished and a proper signal is given and understood. (1) Signal systems other than manual shall be protected against unauthorized use, breakage, weather or obstruction which will interfere with safe operation. In the event of any known malfunction, an alternate signal system shall be used or all motion shall be stopped.(h) If the operator becomes aware of a safety problem and needs to communicate with the signal person, the operator shall safely stop operations. Operations shall not resume until the operator and signal person agree that the problem has been resolved.(i) All directions given to the operator by the signal person shall be given from the operator's direction perspective.(j) Communication with multiple cranes/derricks. Where a signal person(s) is in communication with more than one crane/derrick, a system shall be used for identifying the crane/derrick each signal is for, as follows: (1) for each signal, prior to giving the function/direction, the signal person shall identify the crane/derrick the signal is for, or(2) shall use an equally effective method of identifying which crane/derrick the signal is for.Cal.
