Construction is a potentially high hazard industry for those who work in it, with falls at the top of the hazards list. In fact, falls are the most frequent cause of fatalities at construction sites and annually account for one of every three construction-related deaths. Although there are commonly available methods for preventing falls, the number of construction workers who fall to their deaths has increased in recent years. According to preliminary 2007 fatality data from the Bureau of Labor Statistics (BLS), there were at least 442 construction worker fatalities during 2007 as a result of falls from all causes.
