3. If you use portable heaters, make sure that they are safe.
- Never use propane or kerosene heaters unless they are designed for indoor spaces. Check the instruction manual for safe use.
- Check your portable electric heaters to make sure that they have "tip over" switches which shuts off the power when the heater is not in an upright position.
- Never use extension cords or multiple plug-in devices with portable electric heaters.
- Never increase the fuse size to prevent fuses from blowing (most household wiring should be fused with 15 or 20 amp fuses).
- If fuses blow when you use a portable electric heater, shut off or disconnect as many other electrical appliances possible on the same circuit (or area of the house).
