Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Above 63°C explosive vapour/air mixtures may be formed.
NO open flames. Above 63°C use a closed system, ventilation and explosion-proof electrical equipment.
Use water spray, foam, powder, carbon dioxide.
Fresh air, rest.
Rinse skin with plenty of water or shower.
Wear safety goggles.
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.
CLASSIFICATION & LABELLING
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. Then wash away with plenty of water.
According to UN GHS Criteria
Transportation UN Classification
Keep in the dark. Separated from strong oxidants.
