Portable space heaters are devices employed to heat a small, partially enclosed area. The majority of space heaters are powered by electricity and are used when individuals are unsatisfied with the building’s heating system. Unfortunately, space heaters are highly inefficient and pose a serious fire hazard in the workplace when not used properly.
Hazards
Although space heaters appear to be harmless to some, many hazards can still exist no matter where they are used. In 2005-2009, space heaters caused 32% of home heating fires or structural fires and resulted in thousands of injuries as well as civilian deaths. (See “Fast Stats” on Page 3) The most serious hazards associated with space heaters are fire hazards. The majority of space heater fires are caused when combustibles (e.g. paper, clothing, and curtains) are placed too close or come in contact with the heater causing them to catch fire. Portable electric space heaters have a higher risk of fire than fixed electric heating devices.
Appropriate Heaters
When choosing a portable space heater to use in the workplace, there are a few requirements that must be considered:
- Space heaters must be approved by a Nationally Recognized Testing Laboratory (NRTL), such as Underwriters Laboratory, Inc. (UL). Those not approved, should not be used. (See Figure 2 for space heaters that are not approved for use.)
- Space heaters must have an automatic safety switch (tip-over switch) that turns the unit off if it is tipped over.
- Space heaters must have a thermostatic control which ensures that the unit will turn itself off and pre vent overheating or creating an electrical hazard.
- Space heaters may be regulated by your employer. Check with your supervisor before deciding to use one.
