How should weather conditions influence lift planning and execution?

• A. Consider wind, lightning, rain, ice; postpone if unsafe; monitor forecast and adjust plan and equipment accordingly.
• B. Weather has no impact.
• C. Only work in rain to speed up.
• D. Wind is only considered at full deployment.

Answer: (A)

Weather conditions drive every decision in lift planning and execution. You must evaluate wind, lightning, rain, and ice because each factor changes crane behavior, rigging performance, and worker safety. High winds can cause load sway or crane instability, gusts can exceed safe operating limits, and decisions about allowable wind speeds must be in place before lifting begins. Lightning is a direct outdoor hazard that can force an immediate pause to protect personnel. Rain and ice affect friction, visibility, and surface traction, making rigging, footing, and crane movement more risky. Ice on booms or loads adds unexpected weight and changes handling characteristics.

Because weather can shift quickly, you should monitor forecasts and live conditions and be prepared to adjust the plan and equipment accordingly. That can mean rechecking wind readings, altering rigging or lift procedures, delaying or postponing lifts, or moving operations to a safer location or shelter, all while keeping clear stop-work criteria and communications with the team.

This comprehensive approach is essential because ignoring any of these factors or trying to push through for speed increases the chance of an incident. Postpone if conditions are unsafe, and continually adapt as conditions evolve.
