NY officials: No major public health threat from steam blast

NEW YORK (AP) - An aging steam pipe containing cancer-causing asbestos exploded beneath Fifth Avenue in Manhattan early Thursday, spewing a geyser of white vapor 10 stories high and forcing an evacuation of 49 buildings, but city officials said there was no major public health threat.

Five people, including three civilians, suffered minor injuries from the 6:40 a.m. blast on 21st Street, and officials warned people who may have gotten material on them to bag their clothes and shower immediately as a precaution.

On a street near the blast site, firefighters stripped off their heavy outerwear, bagged it and entered a red decontamination tent in their gym shorts and T-shirts to take showers.

"There was asbestos in the steam line casing," Mayor Bill de Blasio said about eight hours after the explosion, but "the air cleared fairly quickly after the incident. ... There is no meaningful presence of asbestos in the air at this point."

Nevertheless, responders continued to wear masks and their vehicles were hosed off.

De Blasio said it could take days to check and clean the buildings, which include 28 in a "hot zone" closest to the site where the blast left a crater roughly 20 feet by 15 feet in the street.

It was not immediately determined what caused the blast in the 20-inch (50-cm) pipe. The mayor said no work was being done on the pipe at the time.

Daniel Lizio-Katzen, 42, was riding his bike home to the West Village when he saw the plume from the high-pressure steam explosion.

"It was a pretty violent explosion," Lizio-Katzen told the Daily News. "The steam was shooting up into the air about 70 feet. It was pushing up at such a high pressure that it was spewing all of this dirt and debris. The cars around were coated in mud. ... It left a huge crater in the middle of the street."

Brendan Walsh, 22, a senior at New York University, had just gotten off a train and was headed to class when he saw the plume and "a large scatter of debris. ... I was standing behind the police line when a Con Ed worker came rushing over and screaming at police and firefighters to push everyone north because he was worried that there could be secondary manhole explosions."

"Everyone - including the police and firefighters who were standing by - started moving back," he said.

Businesses were braced for the worst as the response dragged on and police and firefighters blocked access to buildings close to the explosion, crippling their neighborhood and their workday. Subway trains were diverted around the blast area.

Similar explosions over the year have drawn attention to the aging infrastructure beneath the streets of the nation's largest city. Fire Commissioner Daniel Nigro said the pipe that blew was installed in 1932.

More than 100 miles of steam pipe run beneath Manhattan, delivering vapor that powers heating and cooling systems, among other functions, in thousands of buildings. The pipes share the crowded underground with subway and commuter rail tunnels, telecommunications and electric cable, and water pipes.

A July 2007 blast tore a deep crater in an intersection near Grand Central Terminal and sent a scalding geyser into the air, leaving one woman dead from a heart attack as she fled. Dozens of people were injured; some suffered horrible burns or had limbs severed.

The 2007 explosion happened after water accumulated in a manhole and traps that were supposed to have relieved pressure became clogged with sealant. Thursday was just a day after the 11th anniversary.

Another deadly Manhattan steam pipe explosion, in August 1989 in the Gramercy Park neighborhood, killed one resident and two Con Ed workers.
