Section 4: First aid measures

If inhaled

Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately.

Skin contact

Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.

Eye contact

Rinse with pure water for at least 15 minutes. Consult a doctor.

Ingestion

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.

Section 5: Firefighting measures

Use dry chemical, carbon dioxide or alcohol-resistant foam. Wear self-contained breathing apparatus for firefighting if necessary.

Section 6: Accidental release measures

Personal precautions

Avoid dust formation. Avoid breathing mist, gas or vapours. Avoid contacting with skin and eye. Use personal protective equipment. Wear chemical impermeable gloves. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas.

Environmental precautions

Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains.

Methods for cleaning up

Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment.
