First Aid Measures
【Ingestion】If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
【Inhalation】Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
【Skin】Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
【Eyes】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
【Storage】Keep away from heat, sparks, and flame. Keep away from sources of ignition. Do not store in direct sunlight. Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
【Handling】Wash thoroughly after handling. Wash hands before eating. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with skin and eyes. 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. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or flames.
Hazards Identification
【Ingestion】The toxicological properties of this substance have not been fully investigated.
【Inhalation】The toxicological properties of this substance have not been fully investigated.
【Skin】Causes skin irritation.
【Eyes】Causes eye irritation.
【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 sp along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.

Exposure Controls/Personal Protection
【Personal Protection】Eyes: Wear appropriate protective eyeglasses or chemical safety ggles 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.
Fire Fighting Measures
【Flash Point】6℃
【Autoignition】155℃
【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. Use water spray to keep fire-exposed containers cool. Will be easily ignited by heat, sparks or flame. Containers may explode when heated. Extinguishing media: Use water spray to cool fire-exposed containers. For large fires, use water spray, fog or alcohol-resistant foam. Do NOT use straight streams of water. For small fires, use carbon dioxide, dry chemical, dry sand, or alcohol-resistant foam. Cool containers with flooding quantities of water until well after fire is out.
【Upper exp. limit】17.7
【Lower exp. limit】1.3
【Fire Potential】HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
Accidental Release Measures
【Small spills/leaks】Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Remove all sources of ignition. A vapor suppressing foam may be used to reduce vapors. Water spray may reduce vapor but may not prevent ignition in closed spaces.
Stability and Reactivity
【Disposal Code】1
【Stability】Stable under normal temperatures and pressures.
【Incompatibilities】Strong oxidizing agents and acids. Hydrolyzed with water.
【Decomposition】Nitrogen oxides, carbon monoxide, oxides of nitrogen, irritating and toxic fumes and gases, carbon dioxide.
【Combustion Products】Fire may produce irritating, corrosive and/or toxic gases.
