Portable Heaters

Portable space heaters can provide convenient warmth, but they also pose safety risks if not used correctly.

Portable Heaters with tip over protection.
Portable heaters must have tip-over protection.

The following OSHA guidelines help ensure a safe working environment and reduces the chance of fires or injuries.

  • Approval and Certification: Heaters must be approved and certified by a recognized testing laboratory, such as UL or ETL.
  • Safe Placement: Heaters must be placed away from combustible materials, such as paper, furniture, or curtains.
  • Stable Positioning: The heater must be positioned on suitable level surface to prevent tipping.
  • Internal Sensors: A shutoff switch should be installed that senses when the heater tilts or tips-over.
  • Electrical Safety: Heaters must be plugged directly into a wall outlet, not an extension cord, to reduce fire risk.
  • Overheat Protection: Heaters must have automatic shutoff features to prevent overheating.
  • Workplace Restrictions: Certain areas, like those with flammable gases or materials, may prohibit portable heaters.
  • Inspection and Maintenance: Regular inspections are required to ensure heaters are in good working condition.
