should have an
appropriate Material Safety Data Sheet (MSDS) present. The
MSDS may be obtained from the manufacturer / distributor.
The MSDS will specify the symptoms of overexposure and
first aid to be used. Here is a typical summary. If symptoms of
asphyxia such as headache, drowsiness, dizziness,
excitation, excess salivation, vomiting or unconsciousness are
observed, remove to fresh air. If breathing has stopped, give
artificial respiration.

.
If breathing is difficult, supplemental oxygen maybe required.
If exposure to cryogenic liquids or cold vapor occurs, restore
tissue to normal, body temperature (37°C) as rapidly as
possible and then protect the injured tissue from further
damage and infection.
Rapid warming of the affected areas is best achieved by
bathing it in warm water. The temperature of the water used
should not exceed 40°C. Under no circumstances should the
frozen part be rubbed either before or after warming. If the
eyes are involved, flush them thoroughly with warm water for
at least 15 minutes. In case of massive exposure, remove
clothing while showering with warm water. The patient should
not drink alcohol or smoke.
CALL A PHYSICIAN
IMMEDIATELY.
