| Hazards Identification | Back to Contents | 【Ingestion】
Causes gastrointestinal tract burns. The toxicological properties of this substance have not been fully investigated. | 【Inhalation】
Causes chemical burns to the respiratory tract. The toxicological properties of this substance have not been fully investigated. | 【Skin】
Causes skin burns. | 【Eyes】
Causes eye burns. | 【Hazards】
Vapors form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. 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】
26.1 | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam. | 【Lower exp. limit】
1.13 | 【Fire Potential】

| 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. Use water spray to knock-down vapors. Do not use water on material itself. Neutralize spilled material with crushed limestone, soda ash, or lime. |
