This recommendation is advisory only and must be evaluated by an Industrial Hygienist familiar with the specific situation of anticipated use by our customers. It should not be construed as offering an approval for any specific use scenario. Body Protection impervious 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 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 point/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: 450 °C - lit. no data available not applicable 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 2,46 g/mL at 25 °C n) o) p) q) r) s) Water solubility Partition coefficient: n- octanol/water Autoignition temperature Decomposition temperature Viscosity Explosive properties no data available no data available no data available no data available no data available no data available t) Oxidizing properties no data available 9.2 10. 10.1 10.2 10.3 10.4 10.5 10.6 11. 11.1 Other safety information no data available STABILITY AND REACTIVITY Reactivity no data available Chemical stability no data available Possibility of hazardous reactions no data available Conditions to avoid Exposure to moisture may affect product quality.
