On Friday, February 12 at approximately 10:30pm the Piermont Fire Department along with the Nyack Fire Department responded 510 Piermont Ave for a report of smoke in the building.
Within 2 minutes of the initial dispatch 13-1 (Chief Goswick Jr) and Piermont Police Department (Det. Peter Boutros) entered the building to assess the situation.
Once within the building they located a heavy smoke condition on the top floor of the apartment complex with a confirmed fire in one of the units. During the evacuation process 13-Command advised control of a signal 12 (working fire) with a report of Party’s still trapped on the top floor.
Our first due engine with a crew of (6) hit the hydrant on the corner of Ash & Piermont Ave and stretched a 1-3/4 line to the fire floor. The first due truck set up the ladder on the roof and the crew began to conduct an interior search as well as opening up while the engine crew extinguished the fire.
10-F.A.S.T. (Nyack FD) was advised that they would be going to work assisting in truck company operations once on scene. 13-Command then requested a additional F.A.S.T. from the Sparkill Fire Department to the scene to replace Nyack.
