Jobs involving aerial lifts cranes and sheathing materials must be properly evaluated with wind conditions.
For buildings with low slope roofs less than 2 12 slope the wind speed at eave height is used.
Eliminating mitigating hazards related to high winds eliminate the hazards by stopping a work task that poses a hazard due to wind conditions i e roof work lifting operations.
