Section 4. First-Aid Measures

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

Rinse skin with plenty of water or shower. Refer for medical attention .

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .

Section 5. Fire-Fighting Measures

Use water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Section 6. Accidental Release Measures

Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

Section 7. Handling and Storage

Fireproof. Separated from strong bases and strong oxidants.
