Which weather condition should prompt postponement of lifts?

• A. Clear skies and calm winds.
• B. Wind gusts just under safe limits.
• C. Lightning and poor visibility.
• D. Mild rain.

Answer: (C)

Weather conditions that create immediate danger to riders and the lift system should lead to postponement. Lightning and poor visibility are the clear red flags here. Lightning poses a direct threat to people and the structure, since strikes can affect towers, cables, and cars, and can cause power disruptions or electrical faults even with protection in place. Poor visibility prevents the operator from reliably seeing approaching loads, signals, or emergencies, and makes rescue or evacuation actions unreliable. In contrast, clear skies and calm winds present minimal risk, and mild rain is generally manageable; wind gusts that stay just under safe limits are still within design allowances and may not require halting operation unless they worsen. So the combination of lightning risk and reduced visibility is the scenario that necessitates postponing lifts.
