From the NY Post:
Con Edison workers did not evacuate the Queens block where a mother of three was killed by a gas-leak explosion despite reading sky-high levels of gas under the street, officials said yesterday.
Yesterday, utility crews discovered a two-inch hole in the gas main just outside the Floral Park home of Ghanwatti Boodram, who died in the explosion.
...the hole in the pipe was likely the cause of the gas smell that a neighbor called to report at 3:34 p.m.
A Con Ed worker responded about 40 minutes later and found low gas levels. But when they starting testing a manhole nearby, they found that the air was more than 80 percent gas -- an extremely volatile mixture.
The worker called in an emergency at 4:15 p.m. and continued to take readings, but no one was evacuated.
Additional crews pulled up 35 minutes later, just as Boodram's house burst into flames.
