    Oxygen Use Precautions

    Oxygen is a safe gas as long as it is used properly. Contrary to what most people believe, oxygen will not explode. Oxygen does, however, support combustion. Therefore, any material that is already burning will burn much faster and hotter in an oxygen enriched atmosphere. It is very important to follow these precautions so that you and your family are safe when you are using your oxygen.
