Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Personal protection: A filter respirator for organic gases and vapours. Remove all ignition sources. Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place.
Separated from strong oxidants. Ventilation along the floor.

Signal: Warning
