Which condition indicates that scaffolding work should be avoided?

Scaffolding work should be avoided in conditions where storms and high winds are present due to the significant safety risks involved. High winds can destabilize scaffolding, making it maintain structural integrity extremely challenging. When combined with storms, the risk escalates further, as not only does wind pressure increase, but rain and other weather elements can impact visibility and worker safety.

In contrast, while wind gusts above 15 mph do pose a concern, storms often entail even greater dangers. Factors like heavy traffic in the area can cause logistical challenges or distractions for workers, but they do not represent a direct risk to the safety of the scaffolding itself. Low temperatures, while they can introduce other concerns such as frost or material contraction, are less critical to the structural integrity and immediate safety issues compared to severe weather conditions. Thus, the presence of storms and high winds clearly indicates that scaffolding work should be set aside to prioritize safety.
