This morning, Station 60 responded to Princeton Day School for the reported smoke condition within the building. LT 603, who is a teacher at PDS, investigated and confirmed heavy smoke coming from a utility room within the occupied school and struck the first alarm. The fire, later confirmed to be from the elevator motor, was knocked down quickly with no extension. Crews overhauled the area and undertook extensive ventilation operations prior to permitting occupancy of the building. Many thanks to the large number of resources who responded in on the assignment.
