An electric heater can be a great convenience in cold weather, but if not used properly, it can be a potential hazard.

AHAM, the Association of Home Appliance Manufacturers, has developed a list of ten simple tips to alert you to the do's and don'ts of using a portable air heater.

Any heater can be dangerous if not used properly. Please be smart, be safe, and enjoy your portable electric air heater!

1. Read the manufacturer's instructions and warning labels before using any portable electric air heater product.
   
2. Keep flammable materials away from heater.
   
3. Unless heater is designed for use outdoors or in bathrooms, DO NOT use in these areas. Parts in the heater may be damaged by moisture. A fire or shock hazard may result.
   
4. Periodically check for secure plug/outlet fit. If the plug does not fit snugly into the outlet or if the plug becomes very hot, the outlet may need to be replaced. Check with a qualified repair person to replace outlet.
   
5. When not in use, unplug heater by pulling straight out from the outlet, not by pulling on the plug at an angle or on the heater's cord. Inspect the cord periodically. DO NOT use heater with a damaged cord. Check with qualified electrician to replace cord.
   
6. Keep heater at least three feet away from objects such as curtains, bedding, furniture, etc. DO NOT block heater air intake or exhaust.
   
7. Place heater on a level, flat surface. DO NOT place heaters on furniture. It may cause a heater to fall, dislodging or breaking parts. This could result in a fire or shock hazard.
   
8. Keep heaters away from children and without supervision, keep heaters out of a child's room.
   
9. String out cords on top of rugs or floors. Placing anything on top of the cord may damage it.
   
10. DO NOT use an extension cord unless absolutely necessary. Using an improper extension cord with high-wattage appliances may cause overheating of the extension cord. If you must use an extension cord, it must be marked "12-guage" or "14-guage" (the smaller the number, the larger the size of the wire).
