Space heaters: staying warm and safe
Portable heating devices may only be used when there is no chance of injury or fire occurring from their use. This applies to both lab-provided and personally owned devices used within Argonne spaces on- and off-site.
Space heaters must be listed by a Nationally Recognized Testing Laboratory (NRTL). The heater should have a label showing one of the listed laboratories. An NRTL-listed space heater will automatically shut off when tipped over or when it overheats.
Space heaters should:
- Have three-pronged (grounded) plugs and use 500 watts or less
- Be placed on a sturdy, level surface, away from combustible materials such as papers, magazines, drapes, cubicles and office furniture. Do not use around flammable vapors, dusts or materials.
- Be plugged directly into a wall outlet — never into a power strip or extension cord
- Be turned off when you leave the room
