Just prior to the accident, the project inspector advised the ironworker to roll up the metal sheets in the direction of the wind.Lesson(s) Learned: 1. Do not handle large materials on open exposed flightline on windy days.2. Even routine mate
5、rial handling operations can be hazardous when that activity is not well planned.Recommendation(s): 1. Materials with large surface areas should be handled INSIDE the shelter of the building-not outside in the wind.2. When working with large material items, provide a second person to help secure and
