First Aid Measures

Ingestion
Seek medical assistance.
Inhalation
Remove to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen.
Skin
Remove contaminated clothing and shoes. Flush with water.
Eyes
Flush with water for at least 15 min., lifting lids occasionally.

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
Highly toxic: contact with water produces toxic gas, may be fatal if inhaled. Inhalation or contact with vapors, substance, or decomposition products may cause severe injury or death.
Skin
See Inhalation.
Eyes
May cause burns.
Hazards
Irritating vapors and toxic gases may be formed when involved in fire.
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 dry chemical, graphite, or dry earth. Do not use water on material itself. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.

Accidental Release Measures

Small spills/leaks
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Keep material dry. Do not use water on material itself. Attempt to stop leak if without undue personnel hazard.

Stability and Reactivity

Incompatibilities
May react very rapidly Reacts exothermically with compounds having active hydrogen atoms (such as acids and water) to form flammable hydrogen gas and caustic products May react with azo/diazo compounds to form explosive products Can react explosively with oxidizing materials.
Stability
No data.
Combustion Products
Irritating vapors and toxic gases may be formed when involved in fire.
