Life Lines, a publication of the Laborers’ Health and Safety Fund, has published an article and infographic about the dangers of heights in construction. From the article:

Working at heights carries risk. About five American construction workers are killed every week by falls from heights, 248 of them in 2011 alone.

New data from the Census of Fatal Occupational Injuries (CFOI) show you don’t have to fall very far for the fall to be deadly. In 2011, CFOI began collecting information on the height of fatal falls. In construction, almost half of the fatal falls (48.8 percent) were from 20 feet or less, 14 percent were from ten feet or less and some were even less than six feet. Only 21.8 percent of victims fell from more than 30 feet.

If visual learning is more your style, much of the same information can be gleaned from the infographic.
