At approx. 00:25 hours the WFD was requested to respond to 300 Old Hook Rd (Care One @ Valley) for an Odor of Burning. An Emerson FD Squad was requested under a mutual aid agreement for automatic response to any type of call in that building. Upon arrival, 15-1 advised units of a confirmed odor with a smoke condition in 2 different locations in the building. Engine 1’s crew arrived and discovered a burnt up motor with a heavy smoke condition in a boiler room. At the same time, Truck 1 and Emerson Squad 28 investigated the boiler room in the north part of the building to find heavy smoke and fire coming from another motor. The truck company used a can to knock the fire and check for extension. Simultaneously the working Fire assignment, bringing a River Vale RIT and Westwood EMS with a Hillsdale FD engine added to the assignment, was filled and crews continued to investigate. Emerson squad 28 found another boiler room in the rear with heavy smoke coming from it. They found another motor that was on fire and knocked it down. It appears the fires were started by an electrical issue but is still under investigation. Thank you to all that assisted.
