OSHA crane signals study guide
29 CFR 1926.1419 sets the general requirements for signals in OSHA's construction crane and derrick standard (Subpart CC). This guide sets out what the federal rule text states on when a signal person must be provided, the types of signals allowed, the Standard Method and non-standard hand signals, new signals and the conditions the employer must demonstrate for them, suitability for site conditions, what the operator must do when the signal link is interrupted or a safety problem arises, the stop or emergency stop signal, direction perspective, and signaling more than one crane/derrick. Related definitions come from 1926.1401, with the signal-related provisions of 1926.1417 and the communication duties in 1926.1424. Hand-signal charts are not described here. goraedu does not certify operators or signal persons, and this is not a certification exam. Your State may run its own OSHA-approved plan with its own rules, so check them too. Every point links to the regulation and quotes its exact words.
When a signal person is required
1926.1419(a) lists three situations, and a signal person must be provided in each of them.
“A signal person must be provided in each of the following situations:”
One situation is when the point of operation is not in full view of the operator. The rule says the point of operation means the load travel or the area near or at load placement.
“The point of operation, meaning the load travel or the area near or at load placement, is not in full view of the operator.”
A second situation applies when the equipment is traveling: a signal person is required when the view in the direction of travel is obstructed.
“When the equipment is traveling, the view in the direction of travel is obstructed.”
A third situation is when, due to site specific safety concerns, either the operator or the person handling the load determines that a signal person is necessary.
“Due to site specific safety concerns, either the operator or the person handling the load determines that it is necessary.”
In Subpart CC, "operator" means a person who is operating the equipment.
“Operator means a person who is operating the equipment.”
Not covered here
The qualification requirements for signal persons (§ 1926.1428) are set out in the separate signal person qualifications set. We only write what an official source states, so study these parts with your certifying program's materials.
Types of signals and hand signals
Signals to operators must be by hand, voice, audible, or new signals.
“Signals to operators must be by hand, voice, audible, or new signals.”
An audible signal is a signal made by a distinct sound or series of sounds; the definition gives a bell, horn, or whistle as examples, without limiting it to them.
“Audible signal means a signal made by a distinct sound or series of sounds. Examples include, but are not limited to, sounds made by a bell, horn, or whistle.”
The "Standard Method" is defined as the protocol in appendix A of Subpart CC for hand signals.
“Standard Method means the protocol in appendix A of this subpart for hand signals.”
When hand signals are used, the Standard Method must be used.
“When using hand signals, the Standard Method must be used (see appendix A of this subpart).”
Exception: non-standard hand signals may be used, in accordance with 1926.1419(c)(2), where use of the Standard Method is infeasible.
“Exception: Where use of the Standard Method for hand signals is infeasible, or 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 paragraph (c)(2) of this section.”
The same exception covers an operation or use of an attachment that is not covered in the Standard Method.
“where an operation or use of an attachment is not covered in the Standard Method, non-standard hand signals may be used”
"Attachments" means any device that expands the range of tasks that can be done by the equipment; the definition gives an auger, drill, magnet, pile-driver and boom-attached personnel platform as examples.
“Attachments means any device that expands the range of tasks that can be done by the equipment. Examples include, but are not limited to: An auger, drill, magnet, pile-driver, and boom-attached personnel platform.”
Not covered here
The hand-signal chart in appendix A is not described or reproduced here. We only write what an official source states, so study these parts with your certifying program's materials.
Non-standard hand signals and new signals
When non-standard hand signals are used, the signal person, the operator and the lift director (where there is one) must contact each other before the operation and agree on the non-standard hand signals that will be used.
“When using non-standard hand signals, the signal person, operator, and lift director (where there is one) must contact each other prior to the operation and agree on the non-standard hand signals that will be used.”
The lift director is part of that agreement only where there is one.
“lift director (where there is one)”
New signals are signals other than hand, voice, or audible signals. They may be used where the employer demonstrates that one of the two conditions in 1926.1419(d) is met.
“Signals other than hand, voice, or audible signals may be used where the employer demonstrates that:”
One option: the new signals provide at least equally effective communication as voice, audible, or Standard Method hand signals.
“The new signals provide at least equally effective communication as voice, audible, or Standard Method hand signals, or”
The other option: the new signals comply with a national consensus standard that provides at least equally effective communication as voice, audible, or Standard Method hand signals.
“The new signals comply with a national consensus standard that provides at least equally effective communication as voice, audible, or Standard Method hand signals.”
The duty to demonstrate that new signals qualify falls on the employer.
“may be used where the employer demonstrates that”
Suitability and keeping the signal link
Both the signals used (hand, voice, audible, or new) and the means of transmitting them to the operator (such as direct line of sight, video, radio, etc.) must be appropriate for the site conditions.
“The signals used (hand, voice, audible, or new), and means of transmitting the signals to the operator (such as direct line of sight, video, radio, etc.), must be appropriate for the site conditions.”
In Subpart CC, "such as" means "such as, but not limited to", so the listed means of transmitting signals are examples.
“Such as means “such as, but not limited to.””
During operations requiring signals, the ability to transmit signals between the operator and signal person must be maintained.
“During operations requiring signals, the ability to transmit signals between the operator and signal person must be maintained.”
If that ability is interrupted at any time, the operator must safely stop operations requiring signals. They stay stopped until the ability is reestablished and a proper signal is given and understood.
“If that ability is interrupted at any time, the operator must safely stop operations requiring signals until it is reestablished and a proper signal is given and understood.”
A dedicated channel is a line of communication assigned by the employer who controls the communication system to only one signal person and crane/derrick, or to a coordinated group of cranes/derricks/signal person(s).
“Dedicated channel means a line of communication assigned by the employer who controls the communication system to only one signal person and crane/derrick or to a coordinated group of cranes/derricks/signal person(s).”
While actually operating the equipment, the operator must not engage in any practice or activity that diverts his/her attention, such as using cellular phones, other than when they are used for signal communications.
“The operator must not engage in any practice or activity that diverts his/her attention while actually engaged in operating the equipment, such as the use of cellular phones (other than when used for signal communications).”
Safety problems and stop signals
If the operator becomes aware of a safety problem and needs to communicate with the signal person, the operator must safely stop operations.
“If the operator becomes aware of a safety problem and needs to communicate with the signal person, the operator must safely stop operations.”
Operations must not resume until the operator and signal person agree that the problem has been resolved.
“Operations must not resume until the operator and signal person agree that the problem has been resolved.”
Anyone who becomes aware of a safety problem must alert the operator or signal person by giving the stop or emergency stop signal.
“Anyone who becomes aware of a safety problem must alert the operator or signal person by giving the stop or emergency stop signal.”
1926.1419(j) carries a note pointing to 1926.1417(y), which requires the operator to obey a stop or emergency stop signal.
“(NOTE: § 1926.1417(y) requires the operator to obey a stop or emergency stop signal).”
The operator must obey a stop (or emergency stop) signal, irrespective of who gives it.
“The operator must obey a stop (or emergency stop) signal, irrespective of who gives it.”
Who signals, direction and multiple cranes
Only one person may give signals to a crane/derrick at a time, except in the circumstances covered by 1926.1419(j).
“Only one person may give signals to a crane/derrick at a time, except in circumstances covered by paragraph (j) of this section.”
All directions the signal person gives the operator must be given from the operator's direction perspective.
“All directions given to the operator by the signal person must be given from the operator's direction perspective.”
Where a signal person (or persons) is in communication with more than one crane/derrick, a system must be used for identifying the crane/derrick each signal is for.
“Where a signal person(s) is in communication with more than one crane/derrick, a system must be used for identifying the crane/derrick each signal is for”
One option for that system: for each signal, before giving the function/direction, the signal person identifies the crane/derrick the signal is for.
“for each signal, prior to giving the function/direction, the signal person must identify the crane/ derrick the signal is for, or”
The other option: the signal person uses an equally effective method of identifying which crane/derrick the signal is for.
“must use an equally effective method of identifying which crane/derrick the signal is for.”
"Crane/derrick" includes all equipment covered by Subpart CC.
“Crane/derrick includes all equipment covered by this subpart.”
