Quick Answer
Kerosene heaters can be safely used indoors with proper precautions and ventilation techniques to minimize risks of carbon monoxide poisoning and fires.
Proper Ventilation
To safely use a kerosene heater indoors, ensure good ventilation by opening windows or installing a ventilation fan. The American Red Cross recommends a minimum of 10 square feet of ventilation per unit, and a fan speed of at least 100 CFM (cubic feet per minute). This helps remove carbon monoxide and other fumes.
Safe Installation and Placement
Always follow the manufacturer’s instructions for installation and placement. A safe distance of at least 3 feet from combustible materials such as curtains, bedding, and furniture is recommended. Also, keep the heater at least 6 feet away from any door or window to prevent carbon monoxide from escaping into adjacent rooms.
Precautions and Maintenance
Regularly inspect the heater for damage or wear. Check the fuel level and fill as needed, but never overfill the tank. Keep a fire extinguisher rated for Class B fires (flammable liquids) nearby, and never leave the heater unattended. Perform routine maintenance tasks such as cleaning the heater and wick assembly, and checking the air intake for blockages.
