On January 4th, companies 33, 44(Kempton), and 61(Hamburg) were dispatched to the 900 block of Dunkles Church Rd. in Greenwich Township for a report of smoke in the basement of a residence. Ladder 33 was on the street in minutes with 3. Chief 44 arrived first and reported nothing showing from a two story residence. Ladder 33 arrived shortly thereafter and sent a crew inside with Chief 44 to investigate. The interior crew found no smoke or odor upon initial investigation. Some water was found near the oil burner and it was determined the smoke was steam from a pressure relief valve on the oil burner. The electric to the oil burner was shut off and all units were returned.
