| First Aid Measures | Back to Contents | 【Ingestion】
Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. | 【Inhalation】
Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. | 【Skin】
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. | 【Eyes】
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. |
| Handling and Storage | Back to Contents | 【Storage】
Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. | 【Handling】
Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Use with adequate ventilation. Wash clothing before reuse. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. |
| Hazards Identification | Back to Contents | 【Inhalation】
Causes respiratory tract irritation. May cause kidney damage. Aspiration may lead to pulmonary edema. Vapors may cause dizziness or suffocation. May cause cardiac abnormalities. Exposure may produce metabolic acidosis. Inhalation at high concentrations may cause CNS depression and asphixiation. May cause burning sensation in the chest. | 【Skin】
Causes skin irritation. May cause cyanosis of the extremities. | 【Eyes】
Causes eye irritation. May cause chemical conjunctivitis and corneal damage. | 【Ingestion】
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause kidney damage. May cause cardiac disturbances. Ingestion of large amounts may cause CNS depression. | 【Hazards】
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion and poison hazard indoors, outdoors or in sewers. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. | 【EC Risk Phrase】

| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure. | 【Respirators】
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary. | 【Exposure Effects】
Effects may be delayed. May cause kidney damage. | 【Exposure limit(s)】
NIOSH REL: C 0.5 ppm (2.4 mg/m3) 15-minute |
| Fire Fighting Measures | Back to Contents | 【Flash Point】
39 | 【Autoignition】
510 | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Will burn if involved in a fire. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Runoff from fire control or dilution water may cause pollution. Extinguishing media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. For large fires, use water spray, fog, or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Water may be ineffective. Do NOT use straight streams of water. | 【Fire Potential】
HIGHLY FLAMMABLE. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors. |
| Stability and Reactivity | Back to Contents | 【Disposal Code】
6 | 【Incompatibilities】
Oxidizing agents, reducing agents, bases, alkali metals. | 【Stability】
Stable at room temperature in closed containers under normal storage and handling conditions. | 【Decomposition】
Carbon monoxide, oxides of sulfur, irritating and toxic fumes and gases, carbon dioxide, hydrogen sulfide. | 【Combustion Products】
Fire will produce irritating, corrosive and/or toxic gases. |
