Administrative data
First-aid measures
Leave the emission area, and move the victim to a well ventilated area. Take off contaminated clothes. Wash the parts of the body contacted with plenty of soap and water. If breathing with difficulty or breathing problems develop, seek immediate medical advice. In case of serious symptoms, seek for medical advice immediately.

- Eyes:
Wash with plenty of water keeping eyelids open. In case of irritation, seek for medical advice.
Fire-fighting measures
Suitable extinguishing media: Use an extinguishing agent suitable for surrounding fires. Do not use water on fires when you suspect that molten metals are present
Extinguishing media not to be used: Do not use water on fires when suspected molten metals are present
Special exposure hazards: Nonflammable/combustible material. Molten metals can produce fumes, vapors and dust that can be toxic and/or respiratory irritants
Special protective equipment for fire-fighters: Wear self-contained breathing apparatus (preferably operated in a positive pressure mode) and protective clothing/goggles to prevent contact with skin and eyes. Do not stay in dangerous zones without self-contained breathing apparatus
Accidental release measures
Use recommended PPE and work clothes to prevent inhalation and contact with skin, mucous membranes and eyes. Leave the emission area. Use breathing apparatus for toxic dust
- Environmental precautions:
Intervene on release. Delimit the area concerned and avoid water and underground water contamination.
- Methods for cleaning up:
Collect the material with available manual and/or mechanical equipment. Operate avoiding any further dispersion of the material. Collect the material and the contaminated soil and dispose according to local and national regulations.
