Wash hands before breaks and at the end of workday. Personal protective equipment Eye/face protection Face shield and safety glasses Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Skin protection 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 - 173401 contaminated 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 and the standard EN 374 derived from it. Body Protection Complete suit protecting against chemicals, 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 particle respirator type N100 (US) or type P3 (EN 143) 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/freezing point Initial boiling point and boiling range Flash point Evaporation rate Form: solid no data available no data available no data available Melting point/range: 140 °C no data available no data available no data available i) Flammability (solid, gas) no data available j) k) l) Upper/lower flammability or explosive limits Vapour pressure Vapour density no data available no data available no data available m) Relative density no data available 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 log Pow: 0,657 no data available no data available no data available no data available no data available 9.2 Other safety information no data available - 173401 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 Exposure to air may affect product quality.
