Extremely flammable. Vapour/air mixtures are explosive.
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
Use powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
PREVENT GENERATION OF MISTS!
Fresh air, rest.
Dry skin. Redness.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Wear safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting.
CLASSIFICATION & LABELLING
Evacuate danger area! Ventilation. 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. Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance.
According to UN GHS Criteria
