12 Aug Crane Operations – JSA

Crane Operations Job Safety Analysis (JSA)

Job / Task

Operation of cranes for lifting, moving, positioning, and setting materials, equipment, and components, including crane setup, rigging, signaling, hoisting, traveling with loads when permitted, load placement, and demobilization.

Purpose

This Job Safety Analysis (JSA), also known as a Job Hazard Analysis (JHA), identifies hazards associated with crane operations and establishes safe work practices and controls to prevent struck-by, caught-between, crushing, electrocution, dropped-load, rigging, overturning, and other material-handling and lifting injuries.

• Understand standard hand signals and the designated communication method.
• Identify overhead power lines and maintain required clearances.
• Evaluate ground conditions, setup location, swing radius, access, and surrounding hazards.
• Stop work when load weight, capacity, rigging, communication, ground conditions, electrical clearance, weather, or other lift conditions are uncertain.

Required PPE

PPE shall be selected based on the crane operation, rigging task, site hazards, and work environment and may include:

• Select a crane with adequate capacity for the planned radius, boom length, configuration, and setup.
• Review the applicable load chart and manufacturer limitations.
• Identify whether the lift requires additional planning, engineering, or a critical-lift procedure under company or site requirements.
• Conduct a pre-lift meeting appropriate to the complexity and hazards of the lift.

Step 2 – Inspect the Work Area

Potential Hazards

• Soft or unstable ground.
• Underground utilities.
• Overhead obstructions.
