1989 Gramercy Park asbestos steam explosion

On August 19, 1989, a large steam explosion in front of a residential building generated a large asbestos containing steam cloud in the Gramercy Park neighborhood of Manhattan, New York City. Two people – a Con Ed worker and a 3rd floor resident – died instantly, and 24 were injured; a third Con Ed worker died the following day. Two hundred people were displaced for months while cleanup crews worked to remove asbestos containing mud from building facades. All apartments were remediated by certified asbestos workers and tested for asbestos in air.

Workers from Con Ed, the major utility company at the time, were repairing a high pressure steam pipe in front of the building when a 30-inch (76 cm) connecting sleeve burst, releasing hot steam and debris upwards. Laboratory testing afterwards determined that the insulating material contained asbestos, which subsequently led to a large-scale evacuation and cleanup. The release from the explosion, in front of 32 Gramercy Park at the corner of 20th Street and Third Avenue, continued for several hours with debris reaching 18 stories. The pipe was covered with asbestos magnesia block insulation which was pulverized and dispersed with the rising steam cloud.

A similar steam pipe explosion occurred in 2007 in midtown Manhattan. Subsequent cleanup activities were complicated because asbestos containing debris was sprayed onto the facades of nearby buildings.

Con Ed originally failed to report the debris contained asbestos but after 4 days, announced the 200 pounds of insulation did contain the cancer causing material, asbestos. Five years later, during a trial on the same issue, pleaded guilty to a conspiracy and environmental law violations in Federal District Court in Manhattan for withholding that information. The final remediation and cleanup cost totaled approximately $90 million, making this one of the most expensive asbestos cleanup projects in history.
