Space heaters are banned from many work areas. They should not be used unless they have had the direct approval of management. Only space heaters that have been checked out by a nationally recognized testing laboratory can be used. Make sure that safety devices, tip over switches and touch sensors are all in working order.

If you do have space heaters at your place of work, make sure that they are at least three feet away from any flammable materials. Never leave space heaters unattended. They should be secured to prevent tipping and fitted with a tip-over switch. Heaters with exposed elements should not be used. Make sure that the space heater is not located in a high traffic area or any other area where it can be a potential tripping hazard.

You should inspect the cord of the space heater to make sure that it is not frayed or otherwise damaged. Plug the space heater directly into the wall rather than using extension cords or multi-plug boxes. Never leave a space heater unattended. When workers leave the room, even for a short period of time, space heaters should be turned off. At the end of the workday, all space heaters in the workplace should be unplugged.
