NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with water spray, alcohol-resistant foam, dry powder, carbon dioxide. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
Use ventilation, local exhaust or breathing protection.
Fresh air, rest.
ON CONTACT WITH LIQUID: FROSTBITE.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes.
Wear safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
CLASSIFICATION & LABELLING
Ventilation. Remove all ignition sources. Remove vapour with fine water spray. Personal protection: self-contained breathing apparatus.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation.
Effects of short-term exposure The liquid may cause frostbite. The substance may cause effects on the kidneys.
Inhalation risk A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
Effects of long-term or repeated exposure
OCCUPATIONAL EXPOSURE LIMITS
Avoid release to the environment because of its impact on the ozone layer.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
