Firing up the space heaters without firing up the office
It’s that time again when the cold sets in and the space heaters come out, but is OSHA okay with their use? Although there are no current federal standards prohibiting portable space heaters in the workplace, certain things can make OSHA hot under the collar.
Many workplaces are just cold, especially older buildings that lack insulation or facilities with doors that constantly open and close letting old man winter have free reign. But before reaching for the portable space heaters to warm things up, employers should consider the following related OSHA regulations:
- 1910 Subpart E: Exit routes and Emergency planning to ensure heaters and cords aren’t placed in areas that create a hazard during an emergency event. This includes 1910.39: Fire prevention planning and ensuring heaters aren’t near flammable or combustible material.
- 1910 Subpart L: Fire protection for ensuring fire extinguishers, alarms, etc. are available and in safe working order.
- 1910 Subpart S: Electrical to ensuring wiring is UL approved, rated for the electrical load, cords and heaters aren’t damaged, and heaters aren’t used with extension cords.
- 1910 Subpart D: Walking-working surfaces to ensure cords aren’t trip hazards.
- 1910.94: Ventilation to ensure non-electric heaters aren’t creating air contaminate or respiratory concerns. (If so, 1910.134: Respiratory protection would come into play.)
- 1910.106: Flammable liquids for non-electric heaters and ensuring they aren’t creating a fire hazard.
- 1910.212: Machine guarding to ensure heating elements are protected from accidental contact by workers.
Do other regulations prohibit the use of space heaters?
The short answer is yes. Permitting the use of space heaters may actually be out of the employer’s control, or there may be additional regulations for ensuring a safe workplace.
National Fire Protection Association (NFPA)
The NFPA estimates a response every 23 seconds to a fire somewhere in the United States. In 2021, local fire departments responded to an astounding 1,353,500 fires that caused 3,800 deaths and almost $16 billion in property damage. Without a doubt, space heaters can be dangerous especially when used near flammable or combustible materials. Don’t let your space heaters be the next statistic.
OSHA often leans on recommendations from the NFPA, so employers should adhere to their recommendations as well. In summary, they require portable heaters to be used only when they don’t present a danger to life or property, be UL approved, have automatic shutoffs for tip over and overheating protection, and be designed so they can’t be easily tipped over.
Building and fire codes
Local and state building and fire codes may also stipulate requirements for protecting workers from the hazards associated with portable space heater use. These codes typically cover the same fire and electrical hazards as OSHA and NFPA; however, they may have additional requirements related to HVAC systems or to building safety.
Insurance companies
Some insurance companies will prohibit the use of portable space heaters, so it’s imperative that employers consult with their providers prior to permitting space heater use in the workplace. Insurance companies see these as no different than a fireplace or a woodstove; a leading cause of fires leading to millions in property damage annually. They may provide strict guidance on the use of portable space heaters or may prohibit their use altogether.
Portable space heater procedures that can keep you out of hot water
By implementing strict safety controls, employers can turn up the heat without turning up the hazards. To keep workers safe and warm:
- Ensure all space heaters are UL-approved for their intended use.
- Double check fire-fighting equipment is available and operable near where portable space heaters will be used.
- Confirm all space heaters have automatic shut-off features when maximum specified temperatures are reached or after a certain amount of operational time.
- Verify all space heaters have tip over protection and a functioning on/off indicator light.
- Inspect portable space heaters regularly to ensure guards over heating coils are in place, appropriate electrical cords are being used with grounds (no extension cords!), are free of damage, and aren’t creating a hazard.
- Maintain a clearance of at least 3 feet from combustible materials and have an appropriate, operable fire extinguisher nearby.
- Prohibit heaters to run when they are unattended.
- Refresh employee knowledge of rules around the use of portable space heaters, which space heaters are allowed, what safety features are required for heaters, and emergency action procedures.
Keys to remember
Portable space heaters are dangerous but can be used safely in the workplace when proper precautions are taken. Before employers allow the use of portable space heaters, they should check with OSHA, other regulatory agencies, and their insurance companies. Developing, implementing, and communicating clear procedures for portable space heater use is key to firing up the heat without firing up the office!
