1 Do NOT remove an object such as a knife, stick, or arrow that is stuck in the body. Doing so may cause more damage and bleeding. Place pads and bandages around the object and tape the object in place.  Put pressure directly on an outer wound with a sterile bandage, clean cloth, or even a piece of clothing.
Carbon Monoxide is always lighter than air down to 32 degrees. Plus it come out of the appliance hot which would put it at the ceiling first. Warmest air in the room is at the ceiling therefore it would linger there the longest.
Humans and other animals with lungs cannot tell when they are breathing in carbon monoxide. Carbon monoxide competes with oxygen for binding sites on hemoglobin. Hemoglobin is the molecule in red blood cells that carries oxygen from our lungs to tissues all over our body, and returns carbon dioxide from the tissues.
