4. First-aid measures*Inhalation: no exposure when used as directed. *Skin contact: wash dust off thoroughly with soap andwater. * Doctor is needed or advisable: consult a physician after prolonged exposure to dust.

5. Fire-fighting measures*Suitable extinguishing media: The product itself is not flammable. *Adapt extinguishing measures tosurroundings.*Special hazard: increased fire hazard during dust formation. *Protective equipment:
breathing protection in the presence of dust.

6. Accidental release measures*Personnel-related precautionary measures: dust should be suction cleaned directly at source.
*Environmental protection measures: no particular environmental protection measures are required.

7. Handling and storage*Handling: Avoid dust formation. Use suction cleaning if unavoidable and when processing at hightemperatures (sublimate formation, see item 10). *Storage: no special measures required.

8. Exposure controls/personal
protection*Exposure thresholds: workplace: tungsten 5 mg/m³, nickel 0.5 mg/m³, cobalt 0.5 mg/m³, iron 1 mg/m³,
inhalable fraction, mean daily value *Dust-like emissions: General 5 mg/m³, nickel 1 mg/m³, cobalt 1 mg/m³*Wastewater emissions: tungsten 5 mg/l, nickel 0.5 mg/l, cobalt 1 mg/l, iron 2 mg/l *Workplace exposure:install suction cleaning when working with dust and sublimate and use at least one FFP3 respirator.
*Environmental exposure: install suction cleaning with filter when working with dust formation. *Do not
empty into drains.

9. Physical and chemical
properties*Appearance: solid grey material *Melting point: 3400°C *Density: (17 to 18.5) g/cm³ at 20°C *Solubility:
insoluble in water, acids and bases; soluble only in hydrofluoric acid or a base in combination with a strongoxidizing agent.

10. Stability and reactivity*Conditions to be avoided: high temperatures in air (strong oxidation beginning around 400°C,sublimation of WO3 beginning around 850°C).
*Substances to be avoided: none

11. Toxicological information*See under item 2.

12. Ecological information*Ecotoxicity: see under item 2. *Mobility: low mobility due to low solubility. *Persistence anddegradability: stable inorganic material. *Bioaccumulation potential: no data available.
