EL PASO, Texas (KTSM) - The Las Cruces Fire Department (LCFD) is urging resident to be safe when using space heaters as colder temperatures are expected over the next few days. LCFD said space heaters are relatively safe when used as directed. However, fire and safety hazards can develop if space heaters are not used properly. Those who use space heaters are also encouraged to carefully follow the manufacturer's directions. LCFD provided the following tips for safe use: Select and use a space heater that has been tested and approved by an independent testing laboratory such as UL – Underwriter’s Laboratories. Avoid using damaged or dilapidated space heaters. Fully inspect the device and its power cord prior to each use. Ensure that the space heater is free of dust and properly clean it, according to manufacturer’s directions, prior to its use. The space heater must be plugged directly to a grounded, three-pronged outlet. Space heaters operate at a high wattage. Avoid plugging into an extension cord, multi-outlet or surge protector. Situate or run the power cord so that it cannot become a trip hazard and do not place power cords above the space heater. Use only space heaters that have thermostatic controls to avoid overheating. Ensure the space heater has an auto-shutoff feature that automatically turns off if it tips or leans. Make sure the space heater is placed in an area with proper ventilation. Do not operate a space heater near fuels, combustibles or anywhere near curtains, blankets, clothing or furniture that could overheat and catch fire. Never operate a space heater near a bathtub, shower or any open water source. Do not leave a space heater on while you sleep or if you leave the room for an extended period. Carefully monitor children and pets so they do not come into contact with an operating space heater.
