This just in from Firefighter Close Calls:

2 Illinois firefighters were injured at a dwelling fire this morning in Markham, Illinois.
1 FF (from Hazel Crest, on mutual aid) is in critical condition with burn injuries after falling through the roof of a single family dwelling fire this morning. He was rescued by the RIT team and is in an area hospital burn unit.
In an unrelated incident at the same fire, another firefighter was injured after a 5" supply line "broke loose" from the pump panel. He was treated and released.

Let's wish them a full speedy recovery.
