First Aid Measures

Ingestion

Wash mouth out with water, provided person is concous. Seek medicall attention.

Inhalation

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.

Skin

Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.

Eyes

Immediately flush eyes with copious amounts of water for at least 15 minutes.

Handling and Storage

Storage

Store in a cool, dry location away from heat and open flame. Keep container tightly closed.

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 irritation.

Skin

May cause irritation.

Eyes

May cause irritation.

Hazards

Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

Exposure Controls/Personal Protection

Personal Protection

Wear appropriate chemical protective gloves, boots and goggles. If contact with the material anticipated, wear appropriate chemical protective clothing.

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

Fire Fighting Measures

Flash Point

85

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.

Fire Potential

May burn but does not ignite readily.

Accidental Release Measures

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 and Reactivity

Disposal Code

2

Stability

Stable under normal temperature and pressure.

Incompatibilities

Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products.

Combustion Products

Fire will produce irritating, corrosive and/or toxic gases.
