Carbon monoxide poisoning action and treatment:

if known. Open all doors and windows to allow fresh air to flow in and evacuate all persons from room or
building. Seek medical support immediately. Contact the emergency gas service and allow them to inspect
the building to ensure it is safe before re-entering.
