Last evening, just before 8pm, Companies were dispatched to an eight story high rise after a tenant reported a smoke alarm activated in an apartment with smoke emitting from under the door. Engine 42, Rescue 4 and Medic 47 responded immediately with 13 personnel. Upon investigation it was determined that the tenant on the seventh floor had started cooking a meal and then left the building. A small stove-top fire had created a moderate smoke condition but did not extend anywhere. Truck 5 assisted with ventilation and once the smoke was evacuated units returned into service.
