First aid measures General information Remove contaminated clothing and shoes immediately, and launder thoroughly before reusing. After inhalation Remove affected person from the immediate area. Ensure supply of fresh air. Summon a doctor immediately. After skin contact When in contact with the skin, clean with soap and water. Seek medical attention. After eye contact Separate eyelids, wash the eyes thoroughly with water (15 min.). Get medical attention if pain still persists. After ingestion Rinse mouth thoroughly with water. Induce vomiting. Summon a doctor immediately. Never give anything by mouth to an unconscious person. 5.) Fire-fighting measures Suitable extinguishing media special powder against burning metal page 2(7)

3 Extinguishing media that must not be used for safety reasons Water; Carbon dioxide; ABC powder; Foam Special exposure hazards arising from the substance or preparation itself, combustion products, resulting gases In the event of fire, the following can be released: Carbon dioxide (CO2); Carbon monoxide (CO) Special protective equipment for fire-fighters Use self-contained breathing apparatus. Wear protective clothing. Other information Run-off water from fire fighting must not be discharged into drains or enter surface water. 6.) Accidental release measures Personal precautions Refer to protective measures listed in sections 7 and 8. Ensure adequate ventilation. Avoid dust formation. Avoid contact with skin, eyes and clothing. Keep away sources of ignition. Environmental precautions Do not discharge into the drains/surface waters/groundwater. Do not discharge into the subsoil/soil. Methods for cleaning up/taking up Small quantities of spilled material may be collected dry or wet. In large quantities: Take up mechanically; When aspirators are used, make sure that they are equiped with efficient dust filtres (HEPA). 7.) Handling and storage Handling Advice on safe handling Product inherent handling risks must be minimised taking the appropriate measures for protection and preventive actions. The working process should be designed to rule out the release of hazardous substances or skin contact as far it is possible by the state of the art. Provide good ventilation of working area (local exhaust ventilation, if necessary). Avoid contact with skin and eyes. Avoid dust formation. Advice on protection against fire and explosion Dust can form an explosive mixture with air. Take precautionary measures against static charges. Keep away from sources of ignition - refrain from smoking. Storage Requirements for storage rooms and vessels Containers which are opened must be carefully resealed and kept upright to prevent leakage. Always keep in containers of same material as the original one. Advice on storage assembly Do not store together with: Mineral acids; Acids; Fluorine; ammonium nitrate; Hydrazine; performic acid; Phosphorous; selenium; sulphur; Titane plus potassium chlorate Further information on storage conditions Keep container tightly closed and dry in a cool, well-ventilated place. Protect against mechanical damage. page 3(7)

Exposure controls / personal protection Exposure limit values cobalt CAS no EC no Cobalt TWA 0,1 mg/m³ Cobalt compounds Co TWA 0,1 mg/m³ chromium CAS no EC no Chromium TWA 0,5 mg/m³ tungsten CAS no EC no Tungsten: soluble TWA 1 mg/m³ STEL 3 mg/m³ Tungsten: insoluble TWA 5 mg/m³ STEL 10 mg/m³ SILICON CAS no EC no Silicon total inhalable dust TWA 10 mg/m³ Silicon respirable dust TWA 4 mg/m³ Exposure controls Personal protective equipment Respiratory protection If workplace exposure limits are exceeded, a respiration protection approved for this particular job must be worn. In case of dust formation, take appropriate measures for breathing protection in the event workplace threshold values are not specified. Respirator HEPA Hand protection In case of intensive contact, wear protective gloves (EN 374). Before use, the protective glove should be page 4(7)

5 tested in any case for its specific work-station suitability (i.e. mechanical resistance, product compatibility and antistatic properties). Adhere to the manufacturer s instructions and information relating to the use, storage, care and replacement of protective gloves. Protective gloves shall be replaced immediately when physically damaged or worn. Design operations thus to avoid permanent use of protective gloves. Eye protection Safety glasses with side protection shield (EN 166) Skin protection Normal chemical work clothing. General protective and hygiene measures Do not eat, drink or smoke during work time. Keep away from foodstuffs and beverages. Wash hands before breaks and after work. Avoid contact with eyes and skin. Do not inhale dust. Remove soiled or soaked clothing immediately. Provide eye wash fountain in work area. Have emergency shower available. 9.) Physical and chemical properties General information Form Colour Odour Powder grey odourless Important health, safety and environmental information Changes in physical state Flash point Fire promoting Properties Oxidizing no data available no data available not oxidizing Density Value 4,5-5,7 g/cm³ Solubility in water 10.) Stability and reactivity insoluble Conditions to avoid Heat, naked flames and other ignition sources. Spontaneously inflammable when finely dispersed. Hydrogen gas is released upon contact with mineral acids and may form explosive compounds with air. Materials to avoid Mineral acids; Acids; Fluorine; ammonium nitrate; Hydrazine; performic acid; Phosphorous; selenium; Sulphur; Titane plus potassium chlorate Hazardous decomposition products No hazardous decomposition products known. Because of the thermal load in the process chamber new phases can be generated. 11.) Toxicological information Acute toxicity Acute oral toxicity LD50 > 7000 mg/kg rat page 5(7)
