Equipment Usage
Cryogenic containers must be operated in accordance with the manufacturer/supplier
instructions. Cryogenic Dewars must be kept in a well-ventilated area protected from weather
and away from heat sources. In applications that use a modular liquid cylinder as a source of
LN2, the supply will need to be replenished at regular intervals to ensure proper operation of the
freezer.
Recommended First Aid
Every site that stores and uses LN2 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.
CALL A PHSYICIAN
IMMEDIATELY.
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.
