The use of portable, electric space heaters should be a temporary measure and is permitted only if properly and appropriately used. Portable electric heaters are high-wattage appliances that have the potential to ignite nearby combustible materials like curtains, beds, sofas, paper, clothing, and flammable liquids. If ignition results from a heater left on and unattended, a major fire could result.
Never use any portable heater that is fueled by kerosene, propane or that produces open flame.
