Narrative
**supplement created 5/28/2019. Revised number of individuals injured to 0 based on information at site. We do not know the extent of the injuries, but 4 people were treated for minor injuries (minor burns, sprain). No further detail has been provided and no update has been provided to the company regarding more serious injury to any individual(s).** at 11:38, national grid dispatch and schedule was notified by the fdny of a fire in a trench at the intersection of kent ave and broadway. Customer meter services (cms) was dispatched to the location.And discovered 12 inch cast iron main leaking and ignited inside the trench. The root cause of the incident was third party damage as a result of city/state construction activity. The gas main was marked out but mark-out failed to mark the location of a tee connection and stub. There was a 1 foot gap between gas main and new water main. Additionally, it was found that the national grid inspector on-site failed to identify the tee that was on the print ids but not on the markout. The contractor hit the stub piece while excavating with the backhoe and the gas main ignited. Field operations located the damage and secured the main on either side of the fire on 3/5/2019 at 20:00. There were 4 injuries on the location (3 males were taken to cornell medical center for fire related injuries and 1 male was taken to wyckoff hospital for a non-fire related injury). Field operations secured the main on either side of the fire at (3/5/2019 at approx. 20:00) using stopper and creating a firewall, causing the temporary interruption of service to (1) customer. Field operations replaced a 7 foot section of the affected main to make the repair. As a result of this incident, an incident analysis was performed. As recommended by principles of pipeline safety management, all future city/state construction daily reports will now include documentation for the inspector to verify the gas markouts and perform the job walk-through.
