What special considerations should be taken when storing materials on a roof or upper levels of a building?

• A. They must be secured to prevent wind from blowing them over the side.
• B. They should be stored indoors whenever possible.
• C. They should be stored on edge to avoid wind damage.
• D. They should be secured with rope only.

Answer: (A)

Wind uplift on exposed upper surfaces makes securing materials essential. When items are on a roof or upper level, gusts can lift and blow them over the edge, creating a serious hazard for people below and potential property damage. Because of that, materials must be secured so wind can’t move them, using proper tie-downs, straps, anchor points, or containment systems rather than relying on rope alone. Avoid storing items on the edge or leaving them unsecured, and whenever possible store indoors or in sheltered areas; if you must place materials on the roof, keep them away from the edge, use rated fasteners, and follow site safety procedures to maintain safe access and prevent hazards.
