Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate chemical protective clothing. Wash away any material which may have contacted the body with copious amounts of water or soap and water. Wear positive pressure self-contained breathing apparatus when fighting fires involving this material. If contact with the material anticipated, wear appropriate chemical protective clothing.
Respirators
Wear positive pressure self-contained breathing apparatus.
Small spills/leaks
Attempt to stop leak if without undue personnel hazard. Do not use water.
Stability
No data.
Incompatibilities
Reacts violently with lithium, calcium.

Fire.
Fire fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources. Do not use water on material itself. Do not apply water to point of leak in tank car or container.
Fire potential
Substance does not burn but will support combustion.
Hazards
Vapors from liquefied gas are initially heavier than air and spread along ground. These are strong oxidizers and will react vigorously or explosivelywith many materials including fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react violently with air, moist air and/or water. Containers may explode when heated. Ruptured cylinders may rocket.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
The toxological properties of this substance have not been fully investigated.
   Inhalation
May be fatal if inhaled. Causes irritation/burns.
   Skin
May be fatal if absorbed through the skin. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.
   Eyes
Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Effects may be delayed.
   Skin
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. Effects may be delayed.
   Eyes
Immediately flush with running water for at least 20 minutes. Effects may be delayed.
