Warren Deavers, from Rescue Squad 3 in Anacostia, sustained burns after the roof of a burning home in the 800 block of 48th Place collapsed and trapped him and two other firefighters on Friday.

Two of the firefighters were able to escape on their own, but a third was pulled from the blaze by a “rapid intervention team.”

Another firefighter was injured during the rescue and a fifth sustained less serious injuries. All were taken to the Washington Hospital Center for treatment.

Firefighter Charles Ryan, who was initially listed in critical condition and sustained the most serious burns, is expected to recover, according to Prince George’s County fire officials. Ryan, who is also the volunteer fire chief in Riverdale, has burns over 40 percent of his body.

D.C. fire department spokesman Pete Piringer said the two other hospitalized firefighters are showing signs of improvement. Investigators are reviewing how the firefighters became trapped by the blaze.
