Inhalation		Use ventilation.	Fresh air, rest.
Skin		Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes		Wear safety spectacles.	Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion	See Effects of short-term exposure	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria WARNING Combustible liquid May be harmful if swallowed and enters airways Transportation UN Classification
STORAGE
Separated from strong oxidants. Ventilation along the floor.
