(See protection codes)

Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.

Fireproof. Separated from strong oxidants, strong bases and strong reducing agents. Well closed.

A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20 °C.

The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. Exposure far above the OEL could cause unconsciousness.

The substance defats the skin, which may cause dryness or cracking.

NO open flames, NO sparks and NO smoking. Above 43 °C use a closed system, ventilation and explosion-proof electrical equipment.

Use ventilation, local exhaust or breathing protection.

Protective gloves.

Wear safety spectacles.

(See procedures)

Fresh air, rest. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower.

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