Shortly before 1:30 pm units from the village of Kiryas Joel were dispatched for a "working chimney fire." Upon arrival of KJFD they found a working fire in a large 3 story multiple dwelling. A 2nd alarm was requested bring Washingtonville R-581 as the FAST. R-581 and Car 3 (Bates) responded with 7 members. Upon arrival the crew was put to work quickly and an additional FAST was requested. The crew from R-581 spit with 3 members stretching a line into floor 1 and 4 members performing a search. Units from Woodbury and Monroe had a large volume of fire in the basement and were forced to withdraw. Shortly after, all units were withdrawn from the building and a defensive attack commenced. The crews from Washingtonville operated a 2.5" line on side 1 and a 1.75" line on side 2. The crew from Washingtonville remained on scene for just over 3 hours before returning.
