Last evening at 18:50 hours Engine 62-2 and Squad 62-1 responded to the Host Resort on Lincoln Highway East to assist Station 63 (LAFAYETTE) with a mass evacuation of the facility due to a sprinkler system malfunction that caused water to come thru the ceilings on the 4th thru 6th floors. There was a large event going on at the time that involved approximately 2000 people so crews from 63 and 62 spent over 2 hours on the scene completing the Evacuation.
