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
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard.
Stability
No data.
Incompatibilities
Incompatible with many classes of compounds, reacting exothermically to release toxic gases Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat.

Fire.
Fire fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.
Hazards
Combustible POISONOUS GASES ARE PRODUCED IN FIRE. Undergoes decomposition to yield toxic fumes including NOx, and it may react violently with alcohols in the presence of a base.

Health.
Exposure effects
   Ingestion
See inhalation.
   Inhalation
CALL FOR MEDICAL AID. VAPOR: POISONOUS. MAY BE FATAL IF INHALED OR ABSORBED THOUGH SKIN. Contact may cause burns to skin and eyes. Move to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. LIQUID: POISONOUS. MAY BE FATAL IF SWALLOWED OR ABSORBED THROUGH SKIN: Contact may burn skin and eyes. Immediately flush skin or eyes with running water for at least 15 minutes. Speed in removing from skin is of extreme importance. Remove and isolate contaminated clothing and shoes at the site. Keep victim quiet and maintain normal body temperature. Effects may be delayed; keep victim under observation. If swallowed and victim is UNCONSCIOUS OR HAVING CONVULSIONS, do nothing except keep victim warm. INHALATION: Poisonous; may be fatal if inhaled. SKIN and EYES: May cause burns. Poisonous, may be fatal if absorbed though skin. INGESTION: Poisnous; May be fatal if swallowed.

First aid
 
   Ingestion
Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
   Inhalation
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
   Skin
Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse.
   Eyes
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.
