Objective

To reinforce the essential safety requirements for planning and executing crane and rigging lifts, with emphasis on critical lift planning, load calculations, hazard assessment, qualified personnel, pre-lift communication, inspection, exclusion zones, and regulatory compliance.

Introduction

Lift planning is one of the most important controls for preventing serious injuries and fatalities during crane and rigging operations. Cranes can move heavy loads over large work areas, create struck-by and crush hazards, and expose workers to falls and electrocution if the lift is not properly planned and controlled. Critical lifts and multiple-crane lifts require even greater attention because the margin for error is smaller and the consequences of failure are severe. A well-developed lift plan, a qualified lift director, trained riggers and signal persons, and clear communication are essential to keeping people, equipment, and property safe.

Presenter Note: Open by stressing that most crane incidents are preventable when the lift is planned before the load is picked. Ask the group to think about the last lift they saw and what could have gone wrong without a plan.

Key Points

• 1. Every lift must start with a hazard assessment and a clear lift plan: Before any load is moved, the crew must identify the hazards that could affect the lift, including overhead obstructions, power lines, ground conditions, weather, load path, landing area, and nearby workers. For critical lifts and multiple-crane lifts, the plan must be more detailed and must address the specific hazards of the operation. The plan should define the load, the rigging method, the travel path, the landing area, communication methods, and the people responsible for each task. [1] [7]
  • Identify the load weight and center of gravity before rigging.
  • Confirm the crane configuration and rated capacity for the planned radius.
  • Review the route of travel and the final landing area.
  • Stop the lift if conditions change or the plan no longer fits the work.
• 2. Critical lifts and tandem lifts require formal planning and communication: A critical lift is not a routine lift. It requires a written lift plan, communication of that plan to everyone involved, and documentation of the pre-job meeting. For tandem or multiple-crane lifts, the plan must be developed by a qualified person, and engineering expertise must be provided when needed. The lift director must review the plan with all workers before the lift begins, and the meeting must be repeated if personnel or equipment change. [4] [5] [6]
  • Treat any lift over the critical threshold or involving more than one crane as a high-risk evolution.
  • Do not begin until the lift director confirms the plan with the crew.
  • Repeat the pre-lift meeting if the plan, crew, or equipment changes.
  • Make sure workers from other companies involved in the lift are included in the briefing.
• 3. Load calculations and rigging selection must be verified before the pick: The crew must know the actual load weight, the center of gravity, and the capacity of the crane and rigging components. Slings, chains, straps, shackles, and lifting attachments must be rated for the load and used according to manufacturer instructions. Poor calculations or incorrect rigging can overload equipment, create an unbalanced lift, or cause the load to shift or drop. [2] [2] [1]
  • Verify the weight of the load, including any attachments or contents.
  • Confirm all rigging hardware has a visible safe working load tag.
  • Use rigging that keeps the load balanced and stable.
  • Do not modify rigging by welding, drilling, or improvising repairs.
• 4. Qualified people must fill the right roles: Lift safety depends on assigning the right people to the right tasks. Operators must be qualified and certified, riggers must be qualified, signal persons must be trained, and the lift director must be competent and qualified for the job. A competent person must be able to identify hazards and take prompt corrective action. If the crew does not know who is directing the lift, who is rigging the load, or who is signaling, the operation is not ready to start. [1] [2] [9]
  • Confirm the operator’s certification before the lift begins.
  • Use a qualified rigger for rigging and load handling tasks.
  • Assign only one signal person unless the situation requires otherwise.
  • Make sure the lift director has authority to stop the job if conditions become unsafe.
• 5. Exclusion zones and communication prevent struck-by and crush incidents: No one should be under a suspended load or inside the swing radius, pinch points, or landing area. Barricades, warning signs, spotters, and clear hand signals or radio communication help keep unauthorized people out of the lift zone. The operator and signal person must maintain effective communication at all times, and only one person should give signals unless a specific hazardous situation requires otherwise. [1] [3] [2]
  • Barricade the swing radius and landing area before the lift starts.
  • Keep all personnel clear of the fall zone and directly under the load.
  • Use standard hand signals or radio communication consistently.
  • Use an air horn or other warning device when needed to alert nearby workers.

Hazard Identification

The following hazards are commonly associated with lift plans, crane operations, and rigging activities. Each hazard can lead to serious injury, fatality, equipment damage, or uncontrolled load movement if not properly controlled.

• Load overload due to incorrect weight calculation, wrong crane configuration, or rigging that is not rated for the lift: Rigging failure, dropped load, crane damage, overturning, struck-by injuries, and fatalities. [2] [1]

(Risk: High)

• Workers entering the swing radius, landing area, or area directly under a suspended load: Crushing injuries, struck-by injuries, fatal injuries, and entrapment if the load shifts or falls. [1] [3]

(Risk: High)

• Contact with overhead power lines or other electrical hazards during crane movement: Electrocution, arc flash, burns, equipment damage, and secondary injuries from panic or equipment movement. [1] [8]

(Risk: High)

• Poor communication between operator, signal person, riggers, and other workers: Conflicting instructions, unexpected load movement, dropped loads, collisions, and struck-by incidents. [3] [4]

(Risk: High)

• Unstable ground, weather, or site conditions affecting crane setup and load travel: Crane instability, tipping, load swing, loss of control, and serious injury to workers nearby. [1] [7]

(Risk: High)

Presenter Note: Ask participants to name the hazards they see most often on their sites, then connect each one back to the lift plan and the controls that should already be in place.

Control Measures

Use the hierarchy of controls to reduce lift risk. Eliminate unnecessary lifts where possible, substitute safer methods or smaller components when practical, engineer the lift through a qualified plan, isolate the hazard with barricades and exclusion zones, and rely on administrative controls such as pre-lift meetings, signal procedures, and competent supervision. PPE is the last line of defense and does not replace planning or exclusion zones.

• Develop a written lift plan for critical lifts and a documented plan for multiple-crane or tandem lifts: Include rigging details, wind speed limits, hoist and travel speed limits where applicable, load distribution, and the need for and position of signal persons. Make the plan available at the worksite and review it before the lift starts. [4]
• Assign a qualified lift director with authority to control the operation: The lift director must be competent, qualified, and able to stop the lift if conditions change. For multiple-crane lifts, ensure the lift director reviews the plan with all involved workers before work begins. [6]
• Verify crane, rigging, and accessory capacities before each lift: Check load charts, rigging tags, sling angles, and attachment points. Confirm that the crane configuration and rigging capacity exceed the planned load and that all components are in serviceable condition. [1] [2]
• Inspect crane setup, ground conditions, and environmental conditions before lifting: Confirm outriggers are deployed and supported, the ground can support the load, and weather conditions remain within safe limits. Stop work if wind, visibility, or site conditions create instability. [1] [1]
• Establish and enforce exclusion zones around the crane, load path, and landing area: Use barricades, warning signs, and spotters to keep workers out of the swing radius, pinch points, and fall zone. No one should travel or work under a suspended load. [1] [2]
• Use a trained signal person and standard communication methods: Use standard hand signals or radio communication, and ensure the operator and signal person can see or hear each other at all times. Limit signals to one person unless a specific hazardous situation requires otherwise. [3] [3]
• Control overhead power line exposure before the lift begins: Survey the site, identify all power lines, maintain required clearance, and coordinate with the utility owner if work must occur near energized lines. Treat all lines as energized until verified otherwise. [8] [8]

Safe Work Procedures

1. Confirm the lift scope, load weight, center of gravity, crane configuration, and rigging method before the lift is approved. [2]
2. Hold a pre-lift meeting with all involved workers, including contractors and support personnel, and review the lift plan, hazards, communication methods, and stop-work authority. [6]
3. Inspect the crane, rigging, hooks, slings, shackles, and accessories before use and remove damaged or untagged equipment from service. [2] [2]
4. Establish barricades and keep all personnel out of the swing radius, fall zone, and area directly under the load. [1] [2]
5. Stop the lift immediately if weather, ground conditions, communication, or equipment condition changes create an unsafe condition. [1]

Presenter Note: Walk the group through the lift from start to finish: planning, inspection, setup, communication, execution, and shutdown. Emphasize that any worker can stop the lift if something does not look right.

Personal Protective Equipment (PPE) Requirements

• Hard Hat: Wear a hard hat whenever working near crane and rigging operations to protect against struck-by hazards from tools, rigging hardware, or shifting loads. Ensure the hard hat is properly fitted and kept in good condition. [2]
  • Inspect for cracks, UV damage, or missing suspension parts.
  • Replace damaged head protection immediately.
• High-Visibility Apparel: High-visibility clothing helps the operator, signal person, and spotters see workers clearly in the lift zone, especially around moving equipment and blind spots. It is especially important when working near traffic, multiple crews, or low-light conditions. [10]
  • Keep garments clean and visible.
  • Use apparel that matches site visibility requirements.
• Work Gloves: Use gloves that provide grip and hand protection when handling rigging, tag lines, shackles, and load attachments. Gloves should fit properly and allow enough dexterity to avoid creating a pinch-point hazard. [2]
  • Keep hands clear of pinch points while tension is being taken up.
  • Do not use damaged or overly loose gloves.
• Safety Glasses: Wear safety glasses to protect against flying debris, dust, and small fragments that may be released during rigging, landing, or equipment handling. Eye protection should be worn throughout the lift operation, not only during setup. [2]
  • Use side protection where required.
  • Replace scratched or damaged lenses.

PPE is important, but it does not make an unsafe lift safe. Proper inspection, planning, exclusion zones, and communication must be in place first. PPE must be worn correctly, kept in serviceable condition, and replaced when damaged or contaminated. [2]

Real-World Example or Case Study

A crew was preparing to set a large mechanical unit using a crane and two riggers. During the pre-lift review, the qualified rigger noticed that the load weight had been estimated from shipping paperwork rather than verified by the actual equipment data plate. The lift director paused the job, confirmed the true weight, and found that the original rigging selection would have exceeded the planned sling angle capacity. The team revised the rigging, adjusted the crane setup, expanded the exclusion zone, and completed the lift safely. The lesson was simple: a short delay to verify load calculations and rigging capacity prevented a dropped load and a likely serious injury. [2] [1]

Presenter Note: Use this example to show that stopping for verification is a strength, not a delay. Ask the group what they would have done if the weight could not be confirmed.

Group Discussion

Discuss the following questions:

1. How do we verify the actual load weight and center of gravity before the lift starts?
2. Who has the authority to stop the lift if the plan changes or conditions become unsafe?
3. What barriers, signals, or spotters will we use to keep people out of the swing radius and fall zone?

Presenter Note: Encourage workers to answer based on their actual site conditions, not just the written procedure. Reinforce that everyone shares responsibility for keeping the lift zone clear.

Emergency Procedures

1. If a load becomes unstable, stops unexpectedly, or rigging begins to fail, stop the lift immediately, warn nearby workers, and keep everyone clear of the load path and landing area. [2]
2. If contact is made with overhead power lines, do not touch the crane, load, or affected equipment. Keep everyone away and contact emergency services and the utility owner immediately. [8]
3. If anyone is injured, call for emergency medical assistance, secure the area, and do not resume work until the incident has been investigated and the lift plan has been reviewed. [1]

Questions and Answers

Use these questions to check understanding and confirm that the crew knows how the lift will be controlled today.

• Q: What makes a lift a critical lift?

A: A critical lift is one that exceeds 75 percent of the crane or derrick rated load chart capacity or requires the use of more than one crane or derrick. These lifts require a formal lift plan and stronger communication controls. [1]

• Q: Who should direct the lift and who should give signals?

A: The lift should be directed by a qualified lift director, and signals should be given by a trained signal person using standard industry hand signals or radio communication. Only one person should give signals at a time unless a specific hazardous situation requires otherwise. [3] [6]

• Q: What should we do if the weather or ground conditions change during the lift?

A: Stop the lift and reassess the operation. Weather, wind, ground stability, and other environmental factors must be monitored continuously, and the crane should not be operated if conditions become unsafe. [1]

Summary

Recap of main points:

• Plan the lift before the load moves, and make sure the plan addresses load weight, rigging, ground conditions, weather, power lines, and communication. [7]
• Use qualified people for the operator, rigger, signal person, and lift director roles. [1] [2]
• Keep people out of the swing radius, fall zone, and directly under the load at all times. [2] [1]
• Stop work immediately if conditions change or if the lift cannot be performed exactly as planned. [1]

Action Items

Specific actions participants should take:

1. Review today’s lift plan and confirm your role before the first pick. [6]
2. Inspect all rigging and verify load ratings, tags, and condition before use. [2]
3. Maintain exclusion zones and use the designated communication method throughout the lift. [3]
4. Stop and escalate any concern about load weight, weather, ground conditions, or power line clearance. [8]

Remember: Plan the lift, verify the load, control the zone, and never take chances with a suspended load.

Report all hazards, near-misses, and incidents to your supervisor immediately.
