This from Josh Boyajian:
Engine 109 went to an automatic alarm last night (5/24/15) at 2444 S. Western. Upon arrival, they advised the MFAO they had fire in a storage unit and asked for a full still. Engine 109 had 1 line lead out and Engine 23 had lines into the sprinkler system. Both Tower 5 and Truck 32 had their mains to the roof. Here are some shots.
