Sunday morning at 0214 Orange County 911 began receiving reports of a house on fire on Rt. 208 north of the village of Washingtonville. Car 3 (Bates) arrived and reported a 2 story private house with fire showing from 2 floors in the rear and requested a 2nd alarm. Car 1 (Skelly) arrived just before E-584 and assumed command. The crew from E-584 (6) split with 2 members performing a primary search and 3 members getting an 1.75" line in place. The crew stretched their line in the front door and began to knock the large volume of fire on the first floor. T-579 arrived and also split their crew. 2 members began to place ground ladder and 2 members stretched a back up line, due to the fact that primary searches were negative and the resident was reporting all occupants outside. T-579 stretched their 1.75" line to the 2nd floor and knocked down all visible fire. Once the visible fire was knocked down on both floors members on 2nd floor still found heavy smoke and high heat conditions. Fire was found in the knee walls and ceilings behind the lathe and plaster. Multiple mutual aid crews were used to open up inside and to cut the roof. Departments who assisted on scene were Salisbury Mills, Maybrook, Goshen, Chester, Vails Gate, Montgomery and Coldenham. Campbell Hall Fire Department established a near by water supply and South Blooming Grove and Cornwall were on stand by in Washingtonville. Units remained on scene throughout the early morning assisting investigators and opening up to check for hot spots. There were 3 minor injuries to firefighters. They were treated on scene and were not transported.
