At 8:44PM, The Briarcliff Manor FD was dispatched to the area of Law Park at the Village Pool Pavilion for a structure fire. PD arrived on scene and confirmed the structure fire with heavy fire overtaking the structure. Briarcliff command requested his structure fire assignment as well as an additional truck to the scene. Units were met with extremely heavy fire conditions on arrival requiring multiple hand lines & master streams to be deployed for the fire suppression. Ladder 52 positioned itself on the pool deck, stretched hand lines and began knocking down the fire with a master stream.
