| Regulatorische Informationen | Chemical: 2-Pentene2-Pentene: Does not have an individual approval but may be used under an appropriate group standard |
| Hazard Classes and Categories | Flam. Liq. 2 (100%)Asp. Tox. 1 (100%)Skin Irrit. 2 (89.1%)Eye Irrit. 2 (89.1%)STOT SE 3 (82.6%) |
| Treatment | Treatment is mainly symptomatic and supportive. Gastric lavage, emesis, and the administration of activated charcoal should be avoided, as vomiting increases the risk of aspiration. (A600) |
| Gesundheitliche Auswirkungen | Petroleum distillates are aspiration hazards and may cause pulmonary damage, central nervous system depression, and cardiac effects such as cardiac arrhythmias. They may also affect the blood, immune system, liver, and kidney. (A600, L1297) |
| Expositionspfade | Oral (L400) |
