Reports at this hour (9PM) are that two firefighters are being transported from Christ Hospital in Oak Lawn to Loyola Hospital in Maywood with serious burns. Commissioner Hoff stated that the two were on the nozzle fighting the fire on the second floor when either the room flashed or the fire got behind them. They issued a mayday and were rescued almost immediately. The two are from the same engine company, a captain with 23 years on the job and a firefighter with two years on the job.

Firefighters had ventilated the roof before moving into the house, but were trapped in the attic area when it “lit up,” said Fire Commissioner Robert Hoff.

Two of the injured firefighters were quickly rescued but suffered burns to their hands and face. One of those firefighters also suffered burns to his respiratory system, Hoff said.

Both were taken in serious-to-critical condition to Advocate Christ Medical Center in Oak Lawn but were expected to be transferred to the Loyola University Hospital Burn Unit, Hoff said.

Fox News reports that the injuries are not thought to be life threatening.
