L7 went down S 11th Street the wrong way and made an excellent position. During the course of operations interior operations were stopped and crews were removed from 119 and defensive operations began. Crews still operated in the exposures controlling extension. 119 later collapsed in the rear. On March 28, 2018 I went to a fire just down the block on S 11th, were the second floor collapsed onto members operating on the first floor resulting in injuries. Good calls by all today.
