Highly flammable. Vapour/air mixtures are explosive.
NO open flames, NO sparks and NO smoking. NO contact with oxidizing agents. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.
Use water spray, alcohol-resistant foam, dry powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
Fresh air, rest.
Rinse and then wash skin with water and soap.
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
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. 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.
According to UN GHS Criteria
Transportation UN Classification
UN Hazard Class: 3; UN Pack Group: II
Fireproof. Separated from strong oxidants. Well closed. Store in an area without drain or sewer access.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.
Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapour mixes well with air, explosive mixtures are easily formed.
Chemical dangers Reacts violently with oxidants and potassium tert-butoxide. This generates fire hazard. Decomposes on burning. This produces irritating fumes.
