Hazards and Protection.
Protection
Wear appropriate protective gloves, clothing and goggles. Always wear thermal protective clothing when handling refrigerated/cryogenic liquids.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Make no contact with the spilled material. ELIMINATE all ignition sources, combustibles and ground all equipment. Take up with sand or other noncombustible absorbent material and place into containers for later disposal.

Fire.
Flash Point,°C
-91
Fire fighting
Extinguish fire with flooding quantities of water or use dry chemical or carbon dioxide.
Fire potential
EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air.
Hazards
Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Containers may explode when heated.

Health.
Exposure effects
   Inhalation
Vapors may cause dizziness or asphyxiation without warning. Some may be irritating if inhaled at high concentrations.
   Skin

Seek medical assistance.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
