First Aid

Appendix C
If a person seems to become dizzy or loses consciousness while working
with liquid nitrogen or carbon dioxide, move to a well-ventilated area
immediately. If breathing has stopped, apply artificial respiration. If
breathing is difficult, give oxygen. Call a physician. Keep warm and at
rest.
If exposed to liquid or cold gas, restore tissue to normal body temperature
(98.6° F) as rapidly as possible, followed by protection of the injured tissue
from further damage and infection. Remove or loosen clothing that may
constrict blood circulation to the frozen area. Call a physician. Rapid
warming of the affected part is best achieved by using water at 108° F.
Under no circumstance should the water be over 112° F, nor should the
frozen part be rubbed either before or after rewarming. The patient
should neither smoke nor drink alcohol.
