after the explosion within two minutes. Two fire companies, quartered in an FDNY firehouse located approximately five blocks to the south, reported hearing and feeling the effects of the massive explosion and alerted the department's dispatch office. Within a short amount of time, the incident escalated to a five-alarm fire, bringing over 250 firefighters to the scene. The American Red Cross in Greater New York was on the scene and helping those displaced, but otherwise not requiring emergency medical services, using nearby Public School 57 as a makeshift center before MTA buses transported them to a Salvation Army shelter at 125th Street. Victims The fatalities in the explosion and collapse included eight people.

The hole in the sewer undermined the soil beneath the gas pipes, causing them to sag and then crack open. Thus it was the combination of the two circumstances which caused the disaster. The NTSB also faulted local residents who did not report the odor of leaking gas, which began at least a day before the explosion, and Con Edison's failure to notify the New York City Fire Department immediately once the leak had been reported to the company. Con Edison sued New York City, and the office of Mayor Bill de Blasio rejected the NTSB's finding of fault on the city's part, saying that the effects of sewer leakage was "localized" and did not cause the gas pipes to break. The utility's suit, filed in June 2015, blamed the gas explosion on neglect by the city. Con Edison said the city was notified on multiple occasions about depressions on the street pavement. In November 2015, an investigation by the New York Public Service Commission accused Con Edison of 11
