First Aid Measures

Ingestion
Seek medical assistance.
Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Skin
Remove and isolate contaminated clothing and shoes. Remove material from skin immediately. Immediately flush with running water for at least 20 minutes.
Eyes
Immediately flush with running water for at least 20 minutes.

Handling and Storage

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.

Hazards Identification

Inhalation
Inhalation or contact with vapors, substance, or decomposition products may cause severe injury or death.
Skin
See Inhalation.
Eyes
See Inhalation.
Hazards
Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact. May be ignited by heat, sparks or flames. Some may decompose explosively when heated or involved in a fire. May burn violently. Decomposition may be self-accelerating and produce large amounts of gases. Vapors or dust may form explosive mixtures with air.
UN (DOT)

Exposure Controls/Personal Protection

Personal Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Exposure Effects
The toxological properties of this substance have not been fully investigated.

Fire Fighting Measures

Fire Fighting
Use water in flooding quantities as fog. Use alcohol foam, 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
Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact.

Accidental Release Measures

Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.

Stability and Reactivity

Stability
No data.
Incompatibilities
Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents Flammable gases are formed by mixing materials in this group with alkali metals Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
Combustion Products
May produce irritating, toxic and/or corrosive gases.
