Upon Ladder 24 and Squrt 51's arrival on the scene of the "fire building" (actually, a vacant construction site), they began an initial interior fire attack.
Engine 22 and Battalion 13 arrived moments later. Squrt 51's officer reported rapidly declining conditions and Battalion 13 ordered interior units to pull out of the building.
The initial aggressive interior attack was changed to a defensive operation, with multiple aerial and master streams in operation as a water battery.
