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.
Carbon dioxide has one carbon atom and two oxygen atoms, and a molecular weight of 44 grams per mole (a certain number of molecules). The oxygen in the air is actually O 2, or molecular oxygen, with a molecular weight of 32. Hence, carbon dioxide has a higher density, or is heavier than oxygen.That is why you need to be careful with carbon dioxide. It can displace the oxygen in a room and lead to asphyxiation.arbon dioxide has one carbon atom and two oxygen atoms, and a molecular weight of 44 grams per mole (a certain number of molecules).
