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 protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Do not use water on material itself. Attempt to stop leak if without undue personnel hazard.
Stability
No data.
Incompatibilities
Can react violently with strong reducing agents such as the very active metals and the active metals Can react with strong oxidizing agents or weaker oxidizing agents under extremes of temperature.

Fire.
Fire fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Do not use water on material itself. Use dry chemical or carbon dioxide. 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.
Fire potential
May burn but does not ignite readily.
Hazards
Most vapors are heavier than air. Air/vapor mixtures may explode when ignited. Container may explode in heat of fire.
Combustion products
Fire may produce irritating and/or toxic gases.

Health.
Exposure effects
The toxological properties of this substance have not been fully investigated.
   Inhalation
Vapors may cause dizziness or suffocation. Exposure in an enclosed area may be very harmful.
   Skin
Contact may irritate or burn skin and eyes.
   Eyes
See Skin.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Wash skin with soap and water.
   Eyes
Immediately flush with running water for at least 20 minutes.
