While the theme for fire prevention week this year is to Cook up Fire Safety in the Kitchen, Sherman Volunteer Fire Department says there are numerous other fire hazards around the house that can be easily mitigated.  Supplemental heating sources such as electric heaters must be a safe distance from any combustibles such as furniture or curtains.   Many people also turn to wood stoves, fireplaces and pellet stoves to help keep the house warm in the winter months.  Sherman firefighters reminded residents to be sure to have those serviced, both the unit itself and the chimney, before the heating season begins.   Blockages in the chimney from creosote buildup, other debris or animal nesting can create both a fire and carbon monoxide hazard.
