LE11 5RGFor information in Europe, call:(01509) 231166Emergency Number, Europe:01509 231166Section 2 - Composition, Information on Ingredients----------------------------------------CAS#: 79-11-8Chemical Name: CHLOROACETIC ACID%: >98EINECS#: 201-178-4----------------------------------------Hazard Symbols:T NRisk Phrases:25 34 50Section 3 - Hazards IdentificationEMERGENCY OVERVIEWToxic if swallowed. Causes burns. Very toxic to aquaticorganisms.Corrosive.Potential Health EffectsEye:May cause irreversible eye injury. Contact with liquid iscorrosive to the eyes and causes severe burns.Skin:Contact with liquid is corrosive and causes severe burns andulceration.Ingestion:May cause perforation of the digestive tract. Causes severedigestive tract burns with abdominal pain, vomiting, and possibledeath. May cause corrosion and permanent tissue destruction of theesophagus and digestive tract. May be harmful if swallowed.Inhalation:Inhalation of high concentrations may cause central nervous systemeffects characterized by nausea, headache, dizziness,unconsciousnessand coma. May cause liver and kidney damage. Causes severeirritationof upper respiratory tract with coughing, burns, breathingdifficulty, and possible coma. May cause pulmonary edema and severerespiratory disturbances. May cause kidney damage.Chronic:May cause liver and kidney damage.Section 4 - First Aid MeasuresEyes:

Get medical aid immediately. Do NOT allow victim to rub eyes orkeepeyes closed. Extensive irrigation with water is required (at least30minutes).Skin:Get medical aid immediately. Immediately flush skin with plenty ofwater for at least 15 minutes while removing contaminated clothingand shoes. Wash clothing before reuse. Destroy contaminated shoes.Ingestion:Never give anything by mouth to an unconscious person. Get medicalaid 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 and move to freshair immediately. If breathing is difficult, give oxygen. Do NOT usemouth-to-mouth resuscitation. If breathing has ceased applyartificial respiration using oxygen and a suitable mechanicaldevicesuch as a bag and a mask.Notes to Physician:Chloroacetic acid causes competitive inhibition of acetateoxidationand acetylates sulfhydryl residues in the liver and kidney.Section 5 - Fire Fighting MeasuresGeneral Information:During a fire, irritating and highly toxic gases may be generatedbythermal decomposition or combustion. Use water spray to keepfire-exposed containers cool. Wear appropriate protective clothingto prevent contact with skin and eyes. Wear a self-containedbreathing apparatus (SCBA) to prevent contact with thermaldecomposition products. Contact with metals may evolve flammablehydrogen gas. Containers may explode when heated. Combustiblematerial; may burn but does not ignite readily.Extinguishing Media:Water or foam may cause frothing. Use water spray to coolfire-exposed containers. Do NOT get water inside containers. Forsmall fires, use dry chemical, carbon dioxide, or water spray. Forlarge fires, use dry chemical, carbon dioxide, alcohol-resistantfoam, or water spray. Cool containers with flooding quantities ofwater until well after fire is out.Section 6 - Accidental Release MeasuresGeneral Information:Use proper personal protective equipment as indicated in Section 8.Spills/Leaks:Avoid runoff into storm sewers and ditches which lead to waterways.Clean up spills immediately, observing precautions in theProtectiveEquipment section. Avoid generating dusty conditions. Remove allsources of ignition. Provide ventilation. Do not get water insidecontainers. Cover with dry earth, dry sand, or other noncombustiblematerial followed with plastic sheet to minimize spreading andcontact with water.Section 7 - Handling and StorageHandling:

Storage:awayWash thoroughly after handling. Remove contaminated clothing andwash before reuse. Minimize dust generation and accumulation. Keepcontainer tightly closed. Do not get on skin or in eyes. Do notingest or inhale. Discard contaminated shoes.Store in a tightly closed container. Keep from contact withoxidizing materials. Store in a cool, dry, well-ventilated areafrom incompatible substances. Keep away from metals. Keep away fromreducing agents. Do not store in metal containers. Do not storenearalkaline substances.Section 8 - Exposure Controls, Personal ProtectionEngineering Controls:Facilities storing or utilizing this material should be equippedwith an eyewash facility and a safety shower. Use adequateventilation to keep airborne concentrations low.Exposure LimitsCAS# 79-11-8:United Kingdom, WEL - TWA: 0.3 ppm TWA; 1.2 mg/m3 TWAUnited Kingdom, WEL - STEL: 0.9 ppm STEL; 3.6 mg/m3 STELGermany: 1 ppm TWA; 4 mg/m3 TWAGermany: Skin absorberNetherlands: 1 ppm MAC; 4 mg/m3 MACRussia: 1 mg/m3 TWAPersonal Protective EquipmentEyes:Wear appropriate protective eyeglasses or chemicalsafety goggles as described by OSHA's eye and faceprotection regulations in 29 CFR 1910.133 or EuropeanStandard EN166.Skin:Wear appropriate protective gloves to prevent skinexposure.Clothing:Wear appropriate protective clothing to prevent skinexposure.Respirators:Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Use aNIOSH/MSHA or European Standard EN 149 approvedrespirator if exposure limits are exceeded or ifirritation or other symptoms are experienced.Section 9 - Physical and Chemical PropertiesPhysical State:SolidColor:colorless or whiteOdor:acetic odorpH:1.93 (0.1M)Vapor Pressure:.75 mm Hg @ 20CViscosity:2.16 cp@70CBoiling Point:189 deg C ( 372.20F)Freezing/Melting Point: 62 deg C ( 143.60F)Autoignition Temperature: 470 deg C ( 878.00 deg F)Flash Point: 126 deg C ( 258.80 deg F)Explosion Limits: Lower:8.0.Explosion Limits: Upper:Not availableDecomposition Temperature: Not available
