188.8.131.52.7.1Wear respiratory protection. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Removeall sources of ignition. Evacuate personnel to safe areas. Beware of vapours accumulating to formexplosive concentrations. Vapours can accumulate in low areas.Environmental precautionsPrevent further leakage or spillage if safe to do so. Do not let product enter drains.Methods and materials for containment and cleaning upContain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing andplace in container for disposal according to local regulations (see section 13). Do not flush with water.Keep in suitable, closed containers for disposal.Reference to other sectionsFor disposal see section 13.HANDLING AND STORAGEPrecautions for safe handlingAvoid exposure - obtain special instructions before use.Avoid contact with skin and eyes. Avoid inhalationof vapour or mist.Keep away from sources of ignition - No smoking.Take measures to prevent the build up of electrostaticcharge.184.108.40.206.220.127.116.11Conditions for safe storage, including any incompatibilitiesStore in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which areopened must be carefully resealed and kept upright to prevent leakage.Never allow product to get in contact with water during storage.Recommended storage temperature: 2 - 8 °CMoisture sensitive. Heat sensitive. Over time, pressure may increase causing containers to burstSpecific end usesno data availableEXPOSURE CONTROLS/PERSONAL PROTECTIONControl parametersComponents with workplace control parametersExposure controlsAppropriate engineering controlsAvoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handlingthe product.Personal protective equipmentEye/face protectionTightly fitting safety goggles. Faceshield (8-inch minimum). Use equipment for eye protectiontested and approved under appropriate government standards such as NIOSH (US) or EN166(EU).Skin protectionHandle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching gloves outer surface) to avoid skin contact with this product. Dispose ofcontaminated gloves after use in accordance with applicable laws and good laboratory practices.Wash and dry hands.The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC andthe standard EN 374 derived from it.Body ProtectionComplete suit protecting against chemicals, The type of protective equipment must be selectedaccording to the concentration and amount of the dangerous substance at the specific workplace.Respiratory protectionWhere risk assessment shows air-purifying respirators are appropriate use a full-face respiratorwith multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backupto engineering controls. If the respirator is the sole means of protection, use a full-face supplied airrespirator. Use respirators and components tested and approved under appropriate governmentstandards such as NIOSH (US) or CEN (EU).PHYSICAL AND CHEMICAL PROPERTIESInformation on basic physical and chemical propertiesa)b)c)d)e)AppearanceOdourOdour ThresholdpHMelting point/freezingForm: liquid, clearColour: light yellowpungentno data availableno data availableMelting point/range: -18 °C
