Safety Awareness for Working Around Mobile Cranes

Manual Lifting & Material Handling

The Problem

Mobile cranes are essential tools on construction sites, but they come with serious risks. Struck-by incidents, dropped loads, electrical hazards, and poor visibility can all result in severe injuries or fatalities. Without awareness and proper precautions, working around cranes can quickly become dangerous. Today, we’ll focus on identifying these hazards and learning how to prevent incidents when working near mobile cranes.

Identify the Hazards

  1. Struck-By the Crane or Counterweight
  2. Struck-By the Load
  3. Dropped Objects
  4. Overloading the Crane
  5. Electrocution Hazards
  6. Poor Visibility
  7. Wind and Weather Conditions
  8. Unqualified Operator Errors

We’ll now go step-by-step to discuss each hazard and its solutions.

Safety Practices and Preventative Measures

  1. Struck-By the Crane or Counterweight

    • Hazard: Swinging counterweights or crane parts can strike or crush workers.

    • Solution:
      • Always maintain a safe distance from the crane and counterweights.
      • Never enter areas marked by barricades or warning signs.
      • Stay out of the crane’s blind spots and avoid standing directly in front of or behind it.
  2. Struck-By the Load

    • Hazard: Workers can be struck by moving or suspended loads.

    • Solution:
      • Never stand under a suspended load.
      • Use tag lines to control the load and maintain a safe distance.
      • Stay alert and aware of the crane’s lifting operations.
  3. Dropped Objects

    • Hazard: Tools, equipment, or materials can fall from the crane and strike workers below.

    • Solution:
      • Avoid standing beneath the crane boom or deck.
      • Be cautious of workers placing tools or materials in unsafe positions.
      • Wear a hard hat at all times to protect against falling objects.
  4. Overloading the Crane

    • Hazard: Exceeding the crane's load capacity can cause structural failure or tipping.

    • Solution:
      • Never add materials to a load without approval from a qualified rigger.
      • Follow the crane’s load capacity limits precisely.
  5. Electrocution Hazards

    • Hazard: Cranes that come into contact with power lines can energize the equipment and cause electrocution.

    • Solution:
      • Maintain safe distances from power lines as required by OSHA.
      • If a crane approaches power lines, immediately notify the operator and signal person.
      • Never touch a crane in contact with an energized line—stay clear and alert others.
  6. Poor Visibility

    • Hazard: The crane operator’s limited view can cause accidents, especially in crowded work areas.

    • Solution:
      • Stay visible to the operator and signal person.
      • If a crane is moving toward a hazard, immediately communicate with the signal person to stop operations.
      • Follow designated walkways and avoid blind spots.
  7. Wind and Weather Conditions

    • Hazard: Strong winds can destabilize crane operations.

    • Solution:
      • Adjust your position if the wind picks up suddenly.
      • Be aware of the crane’s boom and load movements during windy conditions.
      • Pause operations if weather conditions become unsafe.
  8. Unqualified Operator Errors

    • Hazard: Mistakes by untrained or unauthorized operators can endanger everyone on-site.

    • Solution:
      • Only authorized, qualified personnel should operate cranes.
      • Never attempt to operate a crane without proper training and certification.
      • Follow site-specific procedures and protocols.

Real-Life Case or Scenario

Where possible, use an actual incident that you have experienced or been involved in.

On a recent job site, a worker ignored barricades around a crane’s swing radius and was struck by a counterweight. Fortunately, the injury was minor, but this could have been fatal. Simple awareness—like staying out of restricted zones—could have prevented this incident.

Employee Responsibilities

  • Always maintain safe distances from cranes and loads.
  • Follow all barricades, warning signs, and designated walkways.
  • Report unsafe conditions or equipment immediately.
  • Never operate a crane unless trained and authorized.

Employer Responsibilities

  • Provide trained, certified crane operators.
  • Ensure cranes are maintained, inspected, and operated safely.
  • Establish clear protocols for crane operations, including swing radius barricades.
  • Train workers on site-specific crane hazards and safe practices.

Discussion & Questions

  • "What are the biggest hazards you’ve noticed when working around mobile cranes?"
  • "Has anyone seen a near-miss or incident related to a crane? How was it handled?"
  • "How do you make sure you stay visible and safe during crane operations?"

Allow workers to discuss and provide feedback.

Commitment/Action Plan

Let’s commit to staying vigilant when working around cranes. Starting today, take an extra moment to identify swing zones, stay clear of suspended loads, and report any unsafe conditions to your supervisor immediately.

Wrap-Up

Mobile crane hazards are preventable when we remain aware, follow proper safety protocols, and communicate effectively. By taking these precautions, we can keep our worksite safe for everyone. Thank you for paying attention and for making safety a priority.

Standards Overview

  • OSHA 1926.1408: Cranes must maintain safe clearances from power lines to prevent electrocution.
  • OSHA 1926.1424: Workers must maintain a safe distance from rotating crane parts, including counterweights.
  • OSHA 1926.1417: Only qualified, trained operators may operate cranes.

These OSHA standards ensure crane operations are safe and hazards are mitigated.
