Ingestion
Seek medical assistance.

Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.

Skin
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.

Eyes
Immediately flush with running water for at least 20 minutes.

Storage
The product must be stored cool and dry in tightly sealed container or tank. Storage tanks must be drained at regular intervals, washed out and inspected. When stored or transported in pressure-resistant tanks the product can be kept under an atmosphere of nitrogen.

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.

Ingestion
See Inhalation.

Inhalation
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns, or death.

Skin
See Inhalation.

Eyes
See Inhalation.

Hazards
Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases. Reaction with water may generate much heat which will increase the concentration of fumes in the air. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

UN (DOT)
2851

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).

Exposure limit(s)
1 ppm ACGIH ceiling

Poison Class
2

Fire Fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use dry chemical, dry sand, or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.

Fire Potential
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.

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.

Incompatibilities
Incompatible with alkyl nitrates, calcium oxide Reaction with alkali metals or alkaline earth metals (except magnesium) will cause incandescence.

Stability
No data.

Decomposition
Boron oxides, hydrogen fluoride.

Combustion Products
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
