1-Bromoethylene - Reference Information
| (IARC) carcinogen classification | 2A (vol. 39, sup 7, 71, 97) 2008 |

| introduction | ethylene bromide is a gas, insoluble in water, soluble in organic solvents such as ethanol, ether, acetone, etc. |
| safety information | inhalation of high concentration of bromoethylene can cause different degrees of anesthesia. Rats inhaled 25000ppm for 7h caused mild anesthesia, and woke up quickly after disengagement, with no abnormality in pathology. Inhalation 50000ppm for 25min caused anesthesia and mild lung and kidney damage. Inhalation 100000ppm for 15min caused deep anesthesia and died for 15min. Long-term inhalation can cause hepatic angiosarcoma in rats. The United States (ACGIH) is listed as a suspected chemical carcinogen in humans and stipulates a threshold value of 20mg/m3. |
| apply | ethylene bromide as a fuel barrier added to improved acrylic fibers for textiles, furniture and industry. |
| Use | As an intermediate of synthetic resin |
| category | harmful gases |
| toxicity classification | poisoning |
| acute toxicity | oral administration-rat LD50: 500 mg/kg; Inhalation-rat LCL0: 50000 PPM/ 7 hours |
| explosive hazard characteristics | open flame mixed with air, explosive when heated |
| flammability hazard characteristics | open flame, heated and combustible; combustion produces toxic bromide smoke |
| storage and transportation characteristics | warehouse ventilation and low temperature drying; light loading and light unloading; separate from combustion-supporting gas cylinders such as oxygen and air |
| fire extinguishing agent | mist water, carbon dioxide, foam, dry powder |
| occupational standard | TWA 5 mg/m3; STEL 10 mg/m3 |
