Safety Tip of the Week - Space Heater Sense

Space Heater Specifications
Space heater too close to combustible material
  • Must be electrically powered and must not take more than 110 volts of electricity to operate. Fuel powered space heaters, such as PROPANE and KEROSENE, are not permitted.
  • Must have a tip-over shutdown feature. If a space heater is knocked over, the unit must automatically shut off.
  • Must be UL (Underwriters Laboratory), or FM (Factory Mutual) approved, and must be labeled accordingly.
  • Must have a thermostat that shuts unit off when a certain temperature is reached.
  • Must be fan driven.
  • Space heaters with heated coils are not permitted.


Specifications for Electric Space Heaters Use
Space heater too close to combustible material
  • Must be kept at least three (3) feet away from any combustible material.
  • Turn off and unplug the heater when the area being heated is not occupied.
  • Nothing should ever be placed on top of or touching a space heater.
  • Always plug into a wall receptacle.
  • Need to be located in plain sight and clearly visible.
  • Hot plates and toaster ovens should never be used for space heating.
  • Your Building Manager should be contacted if it is felt there is inadequate heat in any work area.
  • Never plug space heaters into dedicated data receptacles.
  • Don't use an electric space heater with frayed insulation or broken wires, or one that overheats.
  • If there is a problem with accessibility to electricity, or electrical outlets, please contact your building manager.
