To reduce the risks of carbon monoxide poisoning, Santé publique France recommends:

• Before each winter, have heating and hot water systems and flue ducts systematically inspected and maintained by a qualified professional;

• Ventilate rooms for at least ten minutes every day, keep ventilation systems in good working order, and never block air inlets or outlets;

• Follow the operating instructions for combustion appliances: never run space heaters continuously;

• Always place generators outside buildings; never use appliances not intended for heating purposes, such as stoves, braziers, or barbecues, for heating.
