first aid measures back to contents
【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 back to contents
【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. refrigerator (approx 4 c).
【handling】

wash thoroughly after handling. use with adequate ventilation. 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. 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. 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. can produce delayed pulmonary edema. inhalation of aniline causes anoxia due to the formation of methemoglobinemia. inhalation at high concentrations may cause cns depression and asphixiation.
【skin】

causes skin irritation. may cause irritation and dermatitis. may cause cyanosis of the extremities.
【eyes】

causes eye irritation. may cause chemical conjunctivitis and corneal damage. may cause chemical conjunctivitis.
【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 of fluoride may include salivation, nausea, vomiting, abdominal pain, fever, labored breathing. inorganic fluorides can be harmful. acute exposure to fluorine compounds can lead to digestive tract burns, and abdominal pain. exposure to fluoride compounds can result in systemic toxic effects on the heart, liver, and kidneys. it may also deplete calcium levels in the body leading to hypocalcemia and death. contains fluoride. fluoride can reduce calcium levels leading to fatal hypocalcemia.
【hazards】

when heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.

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】

a respiratory protection program that meets osha's 29 cfr 1910.134 and ansi z88.2 requirements or european standard en 149 must be followed whenever workplace conditions warrant a respirator's use.
【exposure effects】

chronic inhalation and ingestion may cause fluorosis with skeletal abnormalities. may cause methemoglobinemia, which is characterized by chocolate-brown colored blood, headache, weakness, dizziness, breath shortness, cyanosis, rapid heart rate, unconsciousness and possible death. effects may be delayed. chronic exposure to fluoride compounds may cause systemic toxicity.
fire fighting measures back to contents
【flash point】

72
【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. combustible liquid. extinguishing media: use water spray to cool fire-exposed containers. use agent most appropriate to extinguish fire. in case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
【fire potential】

combustible material: may burn but does not ignite readily.
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
【incompatibilities】

oxidizing agents, acids.
【stability】

stable at room temperature in closed containers under normal storage and handling conditions.
【decomposition】

carbon monoxide, oxides of nitrogen, irritating and toxic fumes and gases, carbon dioxide, hydrogen fluoride.
【combustion products】

fire may produce irritating, corrosive and/or toxic gases.
