2,6-二氟苯胺First Aid Measures
【Ingestion】Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious ａnd alert, rinse mouth ａnd drink 2-4 cupfuls of milk or water.
【Inhalation】Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration.
【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】Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper ａnd lower eyelids. Get medical aid.
Handling ａnd Storage
【Storage】Keep away from heat, sparks, ａnd flame. 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】Wash thoroughly after handling. Use only in a well ventilated area. 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. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
2,6-二氟苯胺Hazards Identification
【Inhalation】May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. Aspiration may lead to pulmonary edema. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate ａnd chocolate-brown blood. Vapors may cause dizziness or suffocation. Inhalation of aniline causes anoxia due to the formation of methemoglobinemia. Inhalation at high concentrations may cause CNS depression ａnd asphixiation. May cause burning sensation in the chest.
【Skin】May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. May cause irritation ａnd dermatitis. May cause cyanosis of the extremities.
【Eyes】May cause eye irritation. May cause chemical conjunctivitis ａnd corneal damage.
【Ingestion】May cause gastrointestinal irritation with nausea, vomiting ａnd diarrhea. The toxicological properties of this substance have not been fully investigated. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate ａnd chocolate-brown colored blood. Overexposure may cause methemoglobinemia. 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.

2,6-二氟苯胺Exposure Controls/Personal Protection
【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】May cause methemoglobinemia, which is characterized by chocolate-brown colored blood, headache, weakness, dizziness, breath shortness, cyanosis, rapid heart rate, unconsciousness ａnd possible death. Repeated exposure may cause sensitization dermatitis.
2,6-二氟苯胺Fire Fighting Measures
【Flash Point】43℃
【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. 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: 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. 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
【Stability】Stable at room temperature in closed containers under normal storage ａnd handling conditions.
【Incompatibilities】Strong oxidizing agents.
【Decomposition】Nitrogen oxides, carbon monoxide, irritating ａnd toxic fumes ａnd gases, carbon dioxide, hydrogen fluoride.
【Combustion Products】Fire will produce irritating, corrosive and/or toxic gases.
