cis-2-BUTENE | ICSC: 0397 (November 2019) |
2-Butene, (Z)- cis-Dimethylethylene beta-cis-Butylene (Z)-but-2-ene |
CAS #: 590-18-1 |
UN #: 1012 |
EC Number: 209-673-7 |
ACUTE HAZARDS | PREVENTION | FIRE FIGHTING | |
---|---|---|---|
FIRE & EXPLOSION | Extremely flammable. Gas/air mixtures are explosive. | NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. Use non-sparking handtools. Flame arrester to prevent flash-back from burner to cylinder. | Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with water spray, dry powder, alcohol-resistant foam. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. |

SYMPTOMS | PREVENTION | FIRST AID | |
Inhalation | Dizziness. Unconsciousness. Suffocation. | Use ventilation, local exhaust or breathing protection. | Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. |
Skin | ON CONTACT WITH LIQUID: FROSTBITE. | Cold-insulating gloves. | ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention . |
Eyes | See Skin. | Wear face shield. | First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. |
Ingestion | Do not eat, drink, or smoke during work. |
SPILLAGE DISPOSAL | CLASSIFICATION & LABELLING |
---|---|
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Remove all ignition sources. Shut off cylinder if possible. Ventilation. Isolate the area until the gas has dispersed. NEVER direct water jet on liquid. |
