At 0804 this morning the Washington Township fire Department was dispatched to smoke coming from a residential building. Schooleys Mountian Chief 2 arrived on scene and confirmed smoke showing from the eves of the building. Long Valley engine 1-2 arrived on scene and stretched a hand line to investigate the source of the smoke. After an investigation, crews determined the source of the smoke was caused by an obstruction in the dryer vent. Crews operated for approximately 30 minutes clearing the blockage from the vent. There was no damage to the structure. Long Valley’s crew was assisted by fire fighters from Fairmount Fire Company and Schooleys Mountain Fire Protection Agency.
