First Aid Measures

Ingestion

Seek medical assistance.

Inhalation

Move to uncontaminated atmosphere; if breathing is difficult, give oxygen.

Skin

Wash off with isopropyl alcohol and water; call a physician.

Eyes

Flush with copious amounts of water.

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

Ingestion

See Inhalation.

Inhalation

May cause severe injury or burns.

Skin

See Inhalation.

Eyes

See Inhalation.

Hazards

Sensitive to temperature rises. Above a given Control Temperature they decompose violently and catch fire. May ignite combustibles (wood, paper, oil, clothing, etc.). May ignite spontaneously if exposed to air. May be ignited by heat, sparks or flames. May burn rapidly with flare-burning effect. Containers may explode when heated. Runoff may create fire or explosion hazard.

Exposure Controls/Personal Protection

Personal Protection

Wear protective gloves and clothing and safety goggles.

Respirators

Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.

Fire Fighting Measures

Flash Point

79

Fire Fighting

The temperature of the substance must be maintained at or below the Control Temperature at all times. SMALL FIRES: Water spray or fog is preferred; if water not available use dry chemical, carbon dioxide or regular foam. LARGE FIRES: Flood fire area with water from a distance. Use water spray or fog; do not use straight streams. Move containers from fire area if you can do it without risk. Do not move cargo or vehicle if cargo has been exposed to heat. Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. BEWARE OF POSSIBLE CONTAINER EXPLOSION. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.

Fire Potential

May explode from heat, contamination or loss of temperature control. Particularly sensitive to temperature rises.

Accidental Release Measures

Small spills/leaks

ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch or walk through spilled material. Stop leak if you can do it without risk. SMALL SPILLS: Take up with inert, damp, noncombustible material using clean non-sparking tools and place into loosely covered plastic containers for later disposal.

Stability and Reactivity

Stability

Shock-sensitive. Highly reactive. Heat sensitive.

Incompatibilities

Strongly reduced material such as sulfides, nitrides, and hydrides

Decomposition

May explode or ignite in contact with organic material.

Combustion Products

Flammable and/or toxic gases formed in fires include acetone, isopropyl alcohol, acetaldehyde, and ethane.
