At what windspeed must a qualified person be consulted during crane operation?

• A. 30 mph
• B. 20 mph
• C. 10 mph
• D. 40 mph

Answer: (B)

Wind is a major factor in crane safety because it directly affects load sway, stability, and rigging. When wind reaches a level where its impact on the crane and load becomes a concern, a qualified person—someone trained to assess crane operations, rigging, and weather effects—must be consulted to decide if lifting can safely continue. At 20 mph, gusts can noticeably influence control of the load and the crane’s performance, so the qualified person reviews current conditions, including gust patterns and wind direction, and the crane’s capabilities under those conditions. Their assessment determines whether to proceed with caution, modify movements, or stop operations. This threshold is used to ensure timely risk evaluation before wind-induced risks become critical.
