New Fairfield Volunteer Fire Department responded to a report of a chimney fire Friday night. The fire on Pine Hill Road was brought under control quickly. Anyone using a fireplace and chimney is urged to be aware of fire prevention tips including making sure the wood is seasoned and a hardwood because a few logs of greenwood can build creosote thick enough to start a chimney fire. Creosote is highly flammable and formed when vapor from wet wood mixes with gases and condenses. A professional chimney sweep should inspect the chimney at least annually, but more frequently if the fireplace is lit regularly. Chimney professionals say that a ¼in thickness of creosote means a chimney can burst into flames any minute and should be removed.
