Details surrounding the massive Hayward gas explosion that injured six people and set off a major fire in a neighborhood have been released by the National Transportation Safety Board (NTSB). According to the preliminary report, Pacific Gas & Electric (PG&E) detected gas at ground level near the site of the explosion about an hour after its crew had supposedly capped the original leak. Despite this, PG&E crews began digging operations shortly after and less than an hour later, the massive explosion occurred.
The NTSB report provides a detailed timeline of the event starting hours before the blast. On December 11, at approximately 7:25 am, PG&E was notified by Mayo Asphalt Milling that a service line had been damaged while they were conducting roadwork on East Lewelling Boulevard. By 8:18 am, the repair crew had capped the original leak; however, shortly after this, PG&E crews detected gas at ground level near the accident home.
Despite knocking on doors of the affected homes and those adjacent to it, no one responded. PG&E crews then began digging up the main gas line about an hour later, which ultimately led to the massive explosion that set off a large fire in the neighborhood.
According to the report, the blast demolished one home and severely damaged several others, with Alameda County Fire Department returning to the scene. At least five residents are now filing a lawsuit against the county and responsible parties, citing the NTSB's investigation as evidence of liability.
PG&E released a statement expressing their commitment to working together with regulatory bodies and other entities to ensure the safe delivery of energy to customers. The company acknowledged that their safety responsibility is paramount and offered condolences to those affected by the incident.
