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. Product 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)】1408

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.
