| First Aid Measures | Back to Contents | 【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. |
| Handling and Storage | Back to Contents | 【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 | Back to Contents | 【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. | 【EC Risk Phrase】

| Fire Fighting Measures | Back to Contents | 【Flash Point】
95 | 【Fire Fighting】
Use water in flooding quantities as fog. Use alcohol foam, dry chemical or carbon dioxide. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources. | 【Fire Potential】
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. |
| Accidental Release Measures | Back to Contents | 【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 | Back to Contents | 【Incompatibilities】
Incompatible with strong oxidizing agents, alcohols, bases (including amines) May react vigorously or explosively | 【Stability】
No data. | 【Combustion Products】
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. |
