1. ANSI B30.5 Hand Signals2. Standard Hand Signals

Who ever is in charge of any crane or hoist operations (Contractor, Forman, Superintendent) using any crane or hoist must ensure that a fully competent, qualified and experienced signal person is assigned to work with the crane for as long as it is working within their area of responsibility.

Mobile Crane CommunicationsSafety Consulting, SOP

The code of federal regulations OSHA CFR Part 1926.550 and the American National Standards Institute (ANSI B30.5) Mobile Crane, Crawler And Locomotive Crane Standards requires that a signalperson be present at all times whenever:

1. The crane is working within a boom’s length of power lines.

2. The operator cannot clearly see the load block/hook and the load at all times.

3. The crane is being backed up or moved and the operator cannot see all parts of the crane and its intended path of travel.

Standard Hand SignalsSafety Consulting, SOP

The signalperson assigned to the crane shall:

Be positioned in full view of the operator and if using hand signals close enough for the signals to be seen clearly. The signal persons position must give him/her a full view of the load and equipment at all times without creating a hazard of being struck by the crane and/or load.

The signalperson must be qualified and experienced with the crane and lifting operation.

Responsible for the public and all (unauthorized personnel outside of the crane’s operating radius).

Direct the load so that it never passes over anyone.

Signal Person RequirementsSafety Consulting, SOP

Be in constant communication with the operator at all times with either the standard hand signals as required in accordance with ANSI B30.5 or by direct radio communication.

Hand signals should only be used when the distance between the operator and the signalperson is not great and atmospheric conditions allow for clear visibility.

It is recommended that the signalperson wear highly visible gloves (day-glow orange, yellow or white) to distinguish him/herself from other personnel and make the signals clearer

Signal Person RequirementsSafety Consulting, SOP

Crane operator practices:

The crane operator Shall Not engage in any practices that will divert attention while actually engaged in operating the crane.

The operator Shall Not engage in the operation of the equipment when physically or mentally unfit.

The operator Shall respond to signals given by a designated signalperson only.

The operator Shall obey a stop/emergency stop signal at any time, no matter who gives it,

Crane Operation ProceduresSafety Consulting, SOP

Crane operator practices:

The crane operator Shall be responsible for those operations under the operator’s direct control.

Whenever there is any doubt as to the safety, the operator Shall have the authority to stop and refuse to handle loads until safety has been assured.

If it is desired to give instructions to the operator, other than those provided by the established signal system, the crane operator Shall Stop all crane motions.

Crane Operation ProceduresSafety Consulting, SOP

ANSI B30.5 Standard Hand Signals:

Standard hand signals to the operator shall be in accordance with the standards that are prescribed in ANSI B30.5-3.3.2, unless voice communication equipment (telephone, radio, or equivalent) are utilized.

Signals shall be Discernible or audible at all times. No response shall be made unless signals are clearly understood.

ANSI B30.5 - Hand SignalsSafety Consulting, SOP

It is strongly recommended that 2-way radios be used on all craning operations where the signaling is required. There are far too many accidents that result from misunderstood or misinterpreted hand signals and all could have been avoided by using voice communication.

The signalperson must constantly talk to the operator at all times during loading operations. If for any reason the signalperson stops talking the operator must stop the operation.

Adequate lighting arrangements and radio communications must be provided for all night operations.

Two-Way Radio CommunicationSafety Consulting, SOP

Hand signals shall be post on the equipment or conspicuously at the jobsite.

ANSI B30.5-3.3.3 Special Signals:

For operations not covered by ANSI B30.5-3.3.2, or for special conditions that occur from time to time, additions to or modifications of the standard signals may be required. In all such cases, these special signals shall be agreed upon in advance by both the operator and the signalperson, and should not be in conflict with the standard signals.
