Six Orange County firefighters remained hospitalized and two were released after a rollover crash on a freeway in Irvine, officials said Friday. The single vehicle crash occurred Thursday night when the hand crew truck struck a guard rail and overturned in lanes on state route 241. At the time, the firefighters were returning from a 12 hour shift on the front lines of the massive airport fire. A vehicle ahead of the fire truck swerved to avoid a ladder and the truck swerved too, striking the guardrail on the right shoulder and overturning multiple times. Six firefighters were taken to trauma centers in conditions ranging from “stable to critical.” Two firefighters were treated at Hoag Hospital Irvine and have since been released. Of the six taken to trauma centers, two were admitted in critical condition and are in the intensive care unit. One is considered “critical but stable” and the other’s condition is “quite critical.” Four of the eight firefighters “are more seriously injured than the others,” a spokesperson said. “They’re in tough shape right now,” and Fennessy called the crash “devastating” and a “huge tragedy for our family.”
