Enter them only if it appears safer than remaining out in the weather. Allow people to choose to remain out. Exterior assembly areas must be clear, sound, open areas away from any building or structure. The danger is not in a building tipping over. Glass and debris can fall and sail outward a considerable distance.
Danger declines with distance.
The extreme danger zone is out to at least 30 feet from a taller building. Safest, is beyond a distance of about half the building s height. Some things can tip over. Tall trees pose limited risk of tipping, but chimneys, signs, towers, poles, or other tall and narrow structures may fall all the way over rather than collapse upon themselves or drop debris. Some old masonry buildings also have walls that may tip all the way over.
