Steam pipe 'hot zone'

As many as 500 people remain out of their homes and businesses after a steam pipe explosion spewed asbestos-laden vapor into the air in Manhattan's Flatiron District. This "hot zone" remains off-limits to the public: 5th Avenue from 19th Street to 22nd Street (midway down the block on 19th Street and most of 20th Street and 21st Street on the west side) and East 20th Street and 21st Street and midway down the block on East 19th Street.
