| Hazards and Protection. | |
| Storage | Can be stored for short periods over sodium hydroxide pellets. |
| Handling | All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. |
| Protection | Wear appropriate protective gloves, clothing and goggles. |
| Respirators | Wear positive pressure self-contained breathing apparatus (SCBA). |
| Small spills/leaks | Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to disperse vapors and dilute standing pools of liquid. |
| Stability | Reactive under confinement, extreme caution. Polymerizes easily. |
| Incompatibilities | Reacts with sodium hypochlorite and other chlorinating agents to give the explosive compound 1-chloroazidine Incompatible with silver or aluminum, which induce polymerization May polymerize explosively upon contact with acids. |

| Fire fighting | Do not extinguish fire unless flow can be stopped; use water in flooding quantities as a fog. Solid streams of water may be ineffective. Apply water from as far a distance as possible.If tank car or truck is involved in fire, isolate the surrounding area in a 1/2 mile radius.Dry chemical, alcohol foam, or carbon dioxide are useful for small fires. For large fires: water spray, fog or foam. | |||
| Fire potential | Flammable liquid and vapor. | |||
| Hazards | Irritating vapors are generated when heated. Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. May polymerize in fires with evolution of heat and container rupture. Runoff to sewer may create fire or explosion hazard. Ethyleneimine vapors are not inhibited and may form polymers in vents or flame arresters, resulting in stopping of the vents. Toxic oxides of nitrogen are produced during combustion. Upon treatment with sodium hypochlorite, it gives off the explosive compound 1-chloroazidine. Avoid acids, sodium hypochlorite. If heated under pressure, instability may result. Hazardous polymerization may occur. Avoid contact with silver or aluminum. Explosive polymerization may occur upon contact with acids. Polymerization is catalyzed by carbon dioxide. | |||

| Exposure effects | CNS effects have been seen in exposed workers and animals. Developmental and paternal effects have been noted in experimental animals. |
| Ingestion | Nausea and vomiting may occur. Irritation or burns of the esophagus or gi tract could develop following ingestion. |
| Inhalation | Respiratory tract irritation with coughing and possible delayed pulmonary edema may develop. |
| Skin | Dermal irritation or burns may be seen. This agent is absorbed through the skin. Dermal sensitization may occur. |
| Eyes | Irritation of eyes, nose, and throat may occur. Corneal damage may occur. |
First aid |
|
| Ingestion | Do not induce emesis - dilution: following ingestion and/or prior to gastric evacuation, immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 15 ml/kg in a child). The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. |
| Inhalation | Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. |
| Skin | Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. Wash skin with soap and water. |
| Eyes | In case of contact with substance, immediately flush with running water for at least 20 minutes. |
