(DNAINFO)  Gustavo Solis | November 20, 2015 Won Edison’s faulty pipe joint was the source of the gas leak that ignited the building explosion that killed eight people and injured dozens, state regulators said Thursday.

The utility used uncertified workers to install the pipe, failed to inspect the fusion joint prior to the explosion and did not call firefighters as soon as they got reports of the gas leak, the New York State Department of Public Service found, according to a 97-page report on the building explosion on Park Avenue between 116th and 117th streets on March 2014.

“A utility’s job first and foremost is to safeguard life and property,” said Commission Chair Audrey Zibelman. “We will not shirk nor shy away from demanding all New York utilities meet that requirement each and every day. Ensuring public safety is a fundamental responsibility of the utilities, and assuring the utilities fulfill this important obligation is our core mission.”
