| First Aid Measures | Back to Contents | 【Ingestion】
Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended. | 【Inhalation】
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention. | 【Skin】
Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse. | 【Eyes】
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention. |
| 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】
Fire may produce irritating, corrosive and/or toxic gases. Ingestion or contact (skin, eyes) with substance may cause severe injury or burns. Runoff from fire control or dilution water may cause pollution. | 【Skin】
See inhalation. | 【Eyes】
See inhalation | 【Hazards】
May explode from heat or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames. May burn rapidly with flare-burning effect. Containers may explode when heated. Runoff may create fire or explosion hazard. | 【UN (DOT)】
2158, 2159 |
| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots. | 【Respirators】
Use NIOSH/MSHA approved respirator appropriate for exposure of concern. |
| Fire Fighting Measures | Back to Contents | 【Fire Fighting】
SMALL FIRES: Water spray or fog is preferred; if water not available use dry chemical, carbon dioxide or regular foam. LARGE FIRES: Flood fire area with water from a distance. Use water spray or fog; do not use straight streams. Move containers from fire area if you can do it without risk. Do not move cargo or vehicle if cargo has been exposed to heat. Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Keep substance wet using water spray. Stop leak if you can do it without risk. SMALL SPILLS: Take up with inert, damp, noncombustible material using clean non-sparking tools and place into loosely covered plastic containers for later disposal. |
| Stability and Reactivity | Back to Contents | 【Stability】
No data. | 【Incompatibilities】
Organic compounds can ignite on contact with concentrated peroxides, strongly reduced material such as sulfides, nitrides, and hydrides |
