Appendix
If a person seems to become dizzy or loses consciousness while working
with liquid nitrogen, 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.
