The only "carbon dioxide burns" I am familiar with are those from handling dry ice. As such they are equivalent to "frostbite", i.e. they are a result of freezing tissue. They should be treated like frostbite. Very mild "burns" can be treated by gently warming the affected area and then bandaging it. More severe "burns" need a doctor's attention.
