Portable electric heaters made after 1991 include many new performance requirements to enhance safety.
A tip-over switch on some models will turn the heater off when it is tipped until it is turned upright again.
Some new heaters also include indicator lights to let users know that the heater is plugged in or is turned on.
Some manufacturers include safety controls like infrared or proximity sensors that can turn a heater off when objects come too close, or when children or pets are near.
Use heaters on the floor. Never place heaters on furniture.
Do not use heaters in wet or moist places, such as bathrooms, unless certified for that purpose.
Do not hide cords under rugs or carpets. Placing anything on top of the cord could cause the cord to overheat, and can cause a fire.
Do not use an extension cord unless absolutely necessary. Using a light-duty, household extension cord with high-wattage appliances can start a fire. If you must use an extension cord, it must be marked #14 or #12 A WG; this tells the thickness or gauge of the wire in the cord.
Be sure the plug fits snugly in the outlet. Since a loose plug can overheat, have a qualified repairman replace the worn-out plug or outlet. If the plug feels hot, unplug the heater and have a qualified repairman check for problems. If the heater and its plug are found to be working properly, have the outlet replaced.
If a heater is used on an outlet protected by a ground fault circuit interrupter (GFCI) and the DFCI trips, do not assume the GFCI is broken. Because GFCIs protect the location where leakage currents can cause a severe shock, stop using the heater and have it checked, even if it seems to be working properly.
Broken heaters should ONLY be checked and repaired by a qualified appliance service center.
