Which wind speed triggers stopping exterior work and cleanup?

• A. 20 mph
• B. 15 mph
• C. 25 mph
• D. 10 mph

Answer: (A)

Wind spreading lead dust is a key safety concern during exterior work. When wind speed reaches the specified threshold, the risk that dust will escape containment increases, so stopping exterior work and cleanup protects occupants and workers and helps ensure a safe, effective cleanup later. That threshold is twenty miles per hour. So, at twenty mph or higher, exterior work and cleanup must be halted until conditions improve or containment can be adjusted. Winds well below that (ten or fifteen mph) don’t require stopping, while winds above the threshold (such as twenty-five mph) would also trigger stopping, but the defined trigger value is twenty mph.
