OSHA has cleared a construction company in a dynamite mishap that shattered windows, sent people running for cover and flung chunks of granite as far as a half-mile into a Westchester County, N.Y., neighborhood.

Federal OSHA spokesman John Chavez says the Oct. 3 incident didn't endanger workers, and the neighborhood's safety isn't OSHA's responsibility.

The state Department of Transportation is also investigating. The incident happened as Yonkers Contracting was blasting as part of an Interstate 287 reconstruction project in White Plains.

Executive Vice President John Kolaya says Yonkers Contracting took "all prudent measures," but unforeseen conditions underground sent the rock flying.
