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 victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
【skin】

get medical aid. flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. remove contaminated clothing and shoes.
【eyes】

immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. get medical aid immediately. do not allow victim to rub or keep eyes closed.
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. flammables-area.
【handling】

remove contaminated clothing and wash before reuse. 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. 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.
hazards identification back to contents
【inhalation】

causes respiratory tract irritation. vapors may cause dizziness or suffocation. can produce delayed pulmonary edema. may cause burning sensation in the chest.
【skin】

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

produces irritation, characterized by a burning sensation, redness, tearing, inflammation, and possible corneal injury. lachrymator. may cause chemical conjunctivitis and corneal damage.
【ingestion】

may cause gastrointestinal irritation with nausea, vomiting and diarrhea. 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 hazard indoors, outdoors or in sewers.

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】

effects may be delayed.

【autoignition】

260
【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. extinguishing media: use water spray to cool fire-exposed containers. water may be ineffective. do not use straight streams of water. in case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
【fire potential】

highly flammable: will be easily ignited by heat, sparks or flames.
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. remove all sources of ignition. use a spark-proof tool. provide ventilation. a vapor suppressing foam may be used to reduce vapors.
