• Employer must ensure each signal person meets Qualification Requirements [1926.1428 (c)]

• Two Options - Third Party or Employer• Third Party qualification is portable• Documentation by Third Party or Employer

• Written or Verbal Test• Practical Test

OSHA CFR 1926.1428 – Signal Person Qualifications (continued) • Documentation must specify type of signaling, e.g., voice,

hand signals, or other• Must know and understand types of signals used, e.g.,

“Standard Method” for hand signals• Be competent in the application of the type of signals used• Have a basic understanding of equipment operation and

limitations including crane dynamics involved in swinging and stopping loads and boom deflection from hoisting loads

• Know and understand relevant requirements of CFR 1926.1419 through 1926.1422 and 1926.1428

CHAPTER 3TYPES OF CRANESPARTS OF CRANES

9

Carrier Mount Telescopic Boom

Pedestal & Tower Cranes

Rough Terrain Telescopic Boom

Parts of Cranes• Movable boom – can be raised, lowered, rotated

• Spool with steel cable that extends to end of boom

• Counterweights that offset the weight of the load

CHAPTER 4• GENERAL SAFETY CONSIDERATIONS• DISQUALIFICAITON• GENERAL REQUIREMENTS

General Safety Considerations• Typical PPE will likely include hard hat, safety glasses, gloves, high visibility vest and work

boots.

• Before the lift begins, check that the load hook is centered over the load and that the rigging gear is properly set. Also check that the load stays centered during the lift.

• Watch for power lines to be sure the boom or load doesn’t get too close.

• Watch the boom deflection closely to make sure it doesn’t exceed the load radius.

• Make sure other personnel stay out of the crane operating area and always keep yourself and others from under a suspended load.

• The rotation of the cab and counterweights presents a hazard. Stay well away from its rotation zone.

• Avoid using your hands to control a load. Use a tag line so you can stay a safe distance from the load.

• When an operator is moving a load horizontally, it may swing if the boom stops suddenly. Stay well away from swinging loads.

• Also, pay close attention to weather conditions. Lightning and strong side winds can produce serious hazards. The steel boom can act like a lightning rod and the wind pushing on the load and boom can make cranes unstable.

Signal Person Disqualification• If subsequent actions by the signal person do not

follow agreed upon signals or uses inappropriate signals the employer must:

• Disqualify the person• Prohibit the person from working as a signal person• Retrain and re-qualify the signal person• EXAMPLES

• Not using Standard Method Signals• Using wrong signal, e.g., booming up instead of hoisting up

• The goal of this requirement is to help prevent miscommunication between signal person and crane operator.

CFR 1926.1419 Signals – General Requirements • Signal person must be provided in each of the

following situations:• Where point of operation view is obstructed• When equipment is traveling and the view in the direction of

travel is obstructed• Due to site specific safety concerns – either operator or

person handling the load determines that it is necessary

• Types of Signals• Hand, Voice or New Signals

• A second signaler may be needed if the view of the pick or landing area is obstructed.

CFR 1926.1419 Signals – General Requirements (continued) • When using Hand Signals, you must use the Standard

Method • Found in Appendix A • Exceptions – When 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 1926.1419(c)(2)

• Non-standard hand signals 1926.1419(c)(2) • Must communicate with signal person, operator, and lift

director (if any) the non-standard hand signals that will be used

CFR 1926.1419 Signals – General Requirements (continued)

New Signals – may be used where the employer demonstrates:

• They are equally effective communication as voice, audible, or Standard Method hand signals, or

• The New Signals comply with national consensus standards that provides at least equally effective communication


1419(e) Suitability

Hand, voice, or new signals and their means of transmitting the signals to the operator must be appropriate for the site conditions.

Example: Radio signals would not be suitable if electronic interference on the site prohibits the signals from being readily understood. Hand signals would not be suitable at night or over large distances.

Note: Operators often have a say in what types of signals will be used.


1419(f)

• During operations requiring signals, the ability to transmit signals between the operator and signal person must be maintained.

• If this ability is interrupted at any time, the operator must safely stop operations requiring signals until it is re-established and a proper signal is given and understood.


1419(g)

• 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.

CFR 1926.1419 Signals – General Requirements (continued) 1419(h)

• Only one person may give signals to a crane/derrick at a time, except in circumstances covered in 1419(j) (emergencies)

1419(j)

• Anyone who becomes aware of a safety problem must alert the operator or signal person by giving the stop or emergency stop signal

Note: 1926.1417(y) requires the operator to obey a stop or

emergency stop signal.


1419(k)

• All directions given to the operator by the signal person must be given from the operator’s direction perspective.

• Meaning that the signal person must provide the signals as if he or she was sitting in the operator’s seat and facing the same direction as the operator


1419(m)

• Communication with multiple cranes/derricks• Must use a system to identifying the crane each 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

• Must use equally effective method of identifying which crane /derrick the signal is for.

CHAPTER 5ELECTRONIC AND VOICE

26

CFR 1926.1420 Signals – Radio, telephone or other electronic transmission of signals

• Must test device before to ensure signal transmission is effective, clear, and reliable.

• Signal transmission must be through a dedicated channel, except;

• Multiple cranes/derricks and one or more signal person as may share a dedicated channel for the purpose of coordinating operations.

• Where a crane is being operated on or adjacent to railroad tracks, and the actions of the crane operators need to be coordinated with the movement of other equipment or trains on the same or adjacent tracks.

• The operator’s reception of the signals must be by a hands-free system.

• Hardwired intercom on tower cranes are most reliable.

CFR 1926.1421 -Signals – Voice Signals – Additional Requirements• The operator, signal person and lift director (if any) must be

able to effectively communicate in the language used.

• Prior to beginning operations, the operator, signal person and lift director(if any) must contact each other and agree on the voice signals that will be used. No further meetings needed unless;• Another worker is added or substituted• There is confusion about the signals• Voice signal is to be changed.

• Each voice signal must contain the following three elements, given in the following order:1. Function, e.g., (hoist/boom), direction2. Distance and/or speed3. Function, e.g., hoist/boom stop command

CFR 1926.1421 -Signals – Voice Signals – Additional Requirements (continued)

Examples: • Swing boom right 30-feet, 25-feet, 20 feet, 15-feet,

10-feet, 5-feet, two feet, swing stop.• Load down 20-feet, load down 15-feet, load down 10-

CFR 1926.1422 Hand Signal Chart (continued)

CHAPTER 7• EQUPMENT OPERATION AND LIMITATIONS• COLLAPSE INVESTIGATION

Equipment Operation and Limitations• Maximum rating (tons) – Maximum rig capability – Determined by the

Mfg. ( Metric Ton = 2,204.6 pounds)• Gross Capacity (determined by radius and other factors, jib/outriggers)• Maximum Net Load (accounts for weights of rigging, blocks, headache

ball, stowed fly, auxiliary boom head. Some crane manufacturers also consider rope suspended from the top sheave as also part of the load

• As radius increases, crane capacity decreases• Boom deflection increases radius and causes load to swing• Effect of Quadrant: greatest when over the rear of carrier, least over the

side (All Terrain and Truck cranes)• Longer boom length generally means reduced lifting capacity and

greater boom deflection. • Two Blocking• Personnel clear of lift area

Equipment Operation and Limitations (continued)

• Dynamic Loading – Extra force when load is moving. Not accounted for in the load chart.

• Control through use of tag lines and proper rigging. • Plan lift to avoid sudden stops.• Prohibit side loading of crane.• Know and follow manufacturers recommendations for wind

speed.

• Boom Deflection – affects the positioning of the load. The amount of deflection varies with boom angle and length as well as load weight. Also, equipment with lattice/cable supported booms has different deflection characteristics than equipment with non-lattice booms (hydraulic ram extensible booms).

Deflection Hazard Relating to Signaling• The signal person intends to signal to the operator to hoist up,

since the load needs to be raised straight up. However, the signal person uses the standard signal for booming up in the mistaken belief that this signal is for hoisting up. A struck-by or crushed-by incident could result because, when booming up, the load will move laterally as well as vertically. A failure to understand what it is that the crane needs to do to accomplish a task can also lead to struck-by or crushed-by incidents.

• As a crane booms down, boom deflection tends to increase, which has the effect of lowering the load more than if there were no boom deflection. If the signal person is unfamiliar with this boom characteristic, he or she may fail to signal in time for the load to stop at the correct point or may cause the load to descend too quickly.

Boom Deflection Control• Needs to be discussed with the operator at the beginning of the job• Determined by load weight and boom length• Boom crane up prior to hoist signal• Hoist up until rigging is tight and boom starts to deflect, then boom

up until load comes up or boom tip starts moving towards crane• If obstructions above boom, boom down on load contact with ground• Operators have to precisely adjust the boom elevation and winch

together to keep a load from drifting out when it is lifted off the ground

• Modern cranes can automatically compensate for this. Lift Adjuster, Load Com are names manufacturers use to describe this feature

CHAPTER 8• ELECTRICAL

Electrical

Power Lines • Identify Work Zone

Work Zone = Marking boundaries

All of the following are required:

CHAPTER 8• CRANE STABILITY• BOOM COLLAPSE CAUSES• KEEPING CLEAR OF THE LOAD

Crane Stability• Crane deck must be level and remain level during the lift. This is

determined at set up. Every degree out of level reduces the capacities in the load chart by 25%.

• Outriggers set on firm, level supporting surface.• Outriggers fully extended, or to manufacturer’s

recommendations. • Tires of the crane, when set up, shall be clear of the ground and

must not be supporting any of the weight of the crane or the capacities of “on rubber” applies.

• Radius and boom length is determined at set-up. The shorter the radius and or boom, the greater the crane capacity.

• Load Loss - Need Safety Latches on Hooks. • Synthetic sling padding to protect from abrasive or sharp surfaces

Boom Collapse Common Causes• Improper positioning of the crane• Exceeding lifting capacity• Soil too soft to support outriggers• Load moved too quickly• Oblique pulling of load• Side loading• Improper erection of crane• Boom contact with structure• Load contact with boom

Keeping clear of the load• Where available, hoisting routes must minimize

exposure to employees.• Keep out of areas where a load can swing• Use tag line instead of your hands to control the load• No worker in the fall zone, except for;

• Those hooking, unhooking or guiding a load• Engaged in initial attachment of the load to a component or

structure• Operating a concrete hopper

Keeping clear of the load (continued) • Workers in the fall zone (area under the load) are required to:

• Have load rigged by qualified rigger. • Use hooks with self-closing latches or equivalent; exception

– “J” hooks permitted for wooden trusses

• During Tilt-up or tilt-down; • No employees must be directly under the load• Only essential workers in the fall zone (but not directly

under) – workers guiding load, those closely monitoring and giving instructions regarding the loads movement, those detaching or initially attaching to another component or structure.

Signaling Guidelines for Riggers• Load secure and properly balanced before signaling to lift.

• Verify that planned lift and swing paths are clear of personnel and free of obstructions.

• Verify that the load is free to be lifted and clear of obstruction before giving hoist signal.

• Verify that ropes are not twisted around each other before giving hoist signal.

• Signal the operator to boom or swing until the hook is centered over the load before hoisting.

• Do not direct load movement such that the crane, rope, or load contacts any obstruction.

• Do not give load movement signals while personnel are on the load or hook, unless in a personnel basket.

• Do not direct load movements over personnel.• If the load must remain suspended, give the dog everything

signal.

Moving The Load• The load is secured and properly balanced in the sling or lifting device

before it is lifted.• The lift and swing paths are clear of obstructions and personnel.• Before starting to lift, the following conditions will be verified.• The load is free to be lifted.• Multiple part lines are not twisted around each other in such a manner that

all of the lines will not separate upon application of the load.• The hook is brought over the load in such a manner as to minimize swinging.• The correct slings have been selected for the weight to be lifted.• During lifting, care will be taken that:

• Acceleration or deceleration of the moving load is accomplished in a smooth manner.

• Load, boom, or other parts of the machine do not contact any obstruction.

Test Time• 50 question written test & practical test

• Knowledge and understanding of the type of signals used.

• Be competent in the application of the signals used. • Have a basic understanding of equipment operation and

limitations, including the crane dynamics, involved in swinging and stopping loads and boom deflection from hoisting loads.

• Understand the relevant requirements of OSHA standard 29CFR 1926.1422 and 1428
