Why Heater Safety Cannot Be Ignored

Heaters are one of the leading causes of residential fires and carbon monoxide (CO) incidents. The vast majority of these accidents are preventable. Whether you use a portable electric heater, a gas unit, or a kerosene stove, following basic safety practices protects your family and your home every single day.

General Safety Rules for All Heater Types

  • Keep a 1-metre clear zone: Never place combustible materials — curtains, bedding, clothing, paper — within one metre of any heater.
  • Never leave a heater unattended while sleeping: Turn off portable heaters before going to bed unless they are specifically designed and certified for overnight use.
  • Plug directly into the wall: Avoid using extension cords or power strips with electric heaters. These can overheat and cause fires.
  • Check the cord and casing regularly: Frayed wires, cracked casings, or unusual smells are warning signs — stop using the heater immediately.
  • Keep children and pets supervised: Young children and animals can easily knock over or touch heaters. Use models with cool-touch exteriors and tip-over protection.

Gas Heater Safety

Gas heaters present specific risks due to combustion. Always observe these rules:

  • Ensure adequate ventilation: Never use an unvented gas heater in a sealed room. Always crack a window or use a properly flued unit.
  • Install a carbon monoxide detector: CO is colourless and odourless — you cannot detect it without a sensor. Place CO detectors near sleeping areas and gas appliances.
  • Have the unit serviced annually: A professional service checks for gas leaks, burner condition, and flue integrity.
  • Know the signs of CO poisoning: Headache, dizziness, nausea, and confusion can all indicate CO exposure. If suspected, evacuate immediately and call emergency services.

Kerosene and Oil Heater Safety

  • Only use the correct grade of fuel as specified by the manufacturer.
  • Never refuel a heater while it is lit or still hot.
  • Store fuel in approved, sealed containers away from the heater and living areas.
  • Use in ventilated spaces only — combustion consumes oxygen and produces CO and water vapour.

Electric Heater Safety

  • Do not use electric heaters in bathrooms or wet areas unless they carry the appropriate IP (Ingress Protection) rating for that environment.
  • Never cover an electric heater — it traps heat and can cause a fire.
  • Look for models certified to national or international safety standards (PSE in Japan, CE in Europe, UL in the USA).
