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

Store in a cool dry location. Vent periodically.

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

Irritation, nausea, headache, vomiting. May cause severe injury or death.

Skin

See Inhalation.

Eyes

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. Solid streams of water may spread fire. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.

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

Incompatibilities

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.

Stability

Stable at normal temperatures and pressures.

Decomposition

Oxides of carbon and nitrogen.

Combustion Products

May produce irritating, toxic and/or corrosive gases.
