Pennsylvania chocolate factory after an explosion that killed seven co-workers says flames had engulfed the building, and her arm, when the floor gave way beneath her.

"I think had they not gotten to her when they did, there was a very good chance the number of victims was going to be plus one," said Pagurek, also a captain in the Philadelphia Fire Department
