If you suspect you or your family has been exposed to carbon monoxide, open the doors and windows to air out your home, turn off all the appliances and leave the building.
Contact a public authority to find the source of the carbon monoxide before entering the building again. Seek medical attention for anyone who suffers from the effects of CO poisoning.
