| First Aid Measures | Back to Contents | 【Ingestion】
Do NOT induce vomiting. 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. | 【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. Immediately 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. |
| Handling and Storage | Back to Contents | 【Storage】
Keep away from sources of ignition. Store in a tightly closed container. Keep under a nitrogen blanket. Store in a cool, dry, well-ventilated area away from incompatible substances. After opening, purge container with nitrogen before reclosing. Periodically test for peroxide formation on long-term storage. Addition of water or appropriate reducing materials will lessen peroxide formation. | 【Handling】
Use with adequate ventilation. Ground and bond containers when transferring material. 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 ingestion and inhalation. If peroxide formation is suspected, do not open or move container. Do not use if the material has evaporated to dryness. 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】
Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Causes respiratory tract irritation. May cause kidney damage. High concentrations may cause pulmonary edema and lung hemmorrages. | 【Skin】
Prolonged and/or repeated contact may cause irritation and/or dermatitis. Exposure may cause irritation and possible burns. | 【Eyes】
Contact with eyes may cause severe irritation, and possible eye burns. | 【Ingestion】
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Aspiration of material into the lungs may cause chemical pneumonitis, which may be fatal. May cause blue or greenish-brown urine. | 【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 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 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】
Prolonged or repeated skin contact may cause defatting and dermatitis. | 【Poison Class】

| Fire Fighting Measures | Back to Contents | 【Flash Point】
58 | 【Autoignition】
255 | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Forms peroxides of unknown stability. Containers may explode in the heat of a fire. Combustible Liquid. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. For large fires, use water spray or fog. Do NOT use straight streams of water. Cool containers with flooding quantities of water until well after fire is out. | 【Upper exp. limit】

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. |
| Stability and Reactivity | Back to Contents | 【Disposal Code】
1 | 【Stability】
Stable under normal temperatures and pressures. Prolonged exposure to air and sunlight may form unstable peroxides. | 【Incompatibilities】
Strong oxidizing agents. It is volatile on contact with steam. | 【Decomposition】
Carbon monoxide, carbon dioxide. | 【Combustion Products】
Fire will produce irritating, corrosive and/or toxic gases. |
