Most important symptoms and effects, both acute and delayed Central nervous system depression, Cough, chest pain, Difficulty in breathing, Exposure to high airborne concentrations can cause anesthetic effects., To the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated. Indication of any immediate medical attention and special treatment needed no data available 5. 5.1 5.2 5.3 5.4 6. 6.1 6.2 6.3 6.4 7. 7.1 7.2 7.3 8. 8.1 8.2 FIREFIGHTING MEASURES Extinguishing media Suitable extinguishing media Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Special hazards arising from the substance or mixture no data available Advice for firefighters Wear self contained breathing apparatus for fire fighting if necessary. Further information Use water spray to cool unopened containers. ACCIDENTAL RELEASE MEASURES Personal precautions, protective equipment and emergency procedures Use personal protective equipment. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas. Environmental precautions Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Methods and materials for containment and cleaning up Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations (see section 13). Reference to other sections For disposal see section 13. HANDLING AND STORAGE Precautions for safe handling Avoid contact with skin and eyes. Avoid inhalation of vapour or mist. Keep away from sources of ignition - No smoking.Take measures to prevent the build up of electrostatic charge. Conditions for safe storage, including any incompatibilities Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature: 2 - 8 ??C Handle and store under inert gas. Dry residue is explosive. Specific end uses no data available EXPOSURE CONTROLS/PERSONAL PROTECTION Control parameters Components with workplace control parameters Exposure controls Appropriate engineering controls Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday. Personal protective equipment Eye/face protection Tightly fitting safety goggles. Faceshield (8-inch minimum). Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Skin protection The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. Body Protection Complete suit protecting against chemicals, Flame retardant antistatic protective clothing, The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Respiratory protection Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type AXBEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). 9. 9.1 PHYSICAL AND CHEMICAL PROPERTIES Information on basic physical and chemical properties a) b) c) d) e) f) g) h) Appearance Odour Odour Threshold pH Melting point/freezing point Initial boiling point and boiling range Flash point Evaporation rate Form: liquid no data available no data available no data available no data available 65,0 - 67,0 ??C -17 ??C - closed cup no data available i) Flammability (solid, gas) no data available j) k) l) Upper/lower flammability or explosive limits Vapour pressure Vapour density Upper explosion limit: 11,8 %(V) Lower explosion limit: 1,8 %(V) no data available no data available m) Relative density 0,96 g/cm3 at 25 ??C n) o) p) q) r) s) t) Water solubility Partition coefficient: n- octanol/water Autoignition temperature Decomposition temperature Viscosity Explosive properties Oxidizing properties no data available no data available no data available no data available no data available no data available no data available 9.2 Other safety information no data available 10. 10.1 10.2 10.3 10.4 10.5 10.6 11. 11.1 STABILITY AND REACTIVITY Reactivity no data available Chemical stability no data available Possibility of hazardous reactions no data available Conditions to avoid Heat, flames and sparks.
