First-aid measures
General advice:
Immediately remove contaminated clothing. If the patient is likely to become unconscious, place and transport in stable sideways position (recovery position). Remove affected person from danger area. First aid personnel should pay attention to their own safety.

On ingestion:
Rinse mouth immediately and then drink plenty of water, seek medical attention.
Note to physician:
Treatment: Symptomatic treatment (decontamination, vital functions). If necessary, give oxygen.

Suitable extinguishing media:
water, carbon dioxide
Special protective equipment:
Wear a self-contained breathing apparatus.
Further information:
Keep containers cool by spraying with water if exposed to fire. Shut off or stop source of fuel if possible. Dispose of fire debris and contaminated extinguishing water in accordance with official regulations.
Accidental release measures
Personal precautions:
Sources of ignition should be kept well clear. Ensure adequate ventilation. Wind direction should be noted.
