America's most dangerous jobs

On a construction site, there are many ways to get injured. Trenches can collapse while workers are digging them; kegs of nails can fall from upper floors and bare wires can carry a deadly electric charge.

And the messier the job site, the worse the risk.

But the most common way workers die on the job is from falls, according to OSHA.

Mandated safety training classes have helped to reduce fatalities. But a recent upturn in home building and other construction has brought many inexperienced new workers to the job, said Mickey Kelly, director, New York State Laborers Health and Safety Trust Fund. And that typically leads to an uptick in accidents.
