Hazards and protection. | |
| Storage | Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. |
| 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. Always wear thermal protective clothing when handling refrigerated/cryogenic liquids. |
| Respirators | Wear positive pressure self-contained breathing apparatus (SCBA). |
| Small spills or leaks | Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. |
| Stability | No data. |
| Incompatibilities | Incompatible with strong oxidizing agents like nitric acid. |
| Other hazards | Vapor can form a flammable mixture with air which, if ignited, may release explosive force causing structural damage. |

| Fire fighting | Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. | |||
| Fire potential | EXTREMELY FLAMMABLE. | |||
| Hazards | Containers may explode in fire. Vapor heavier than air and may travel a long distance to a source of ignition and flash back. | |||

Exposure effects | |
| The toxological properties of this substance have not been fully investigated. | |
| Inhalation | Acute effect - Asphyxiation possible. Headaches, dissiness and drowsiness. Slight narcotic effect. |
| Skin | Tissue damage due to frostbite. Vapor is no hazard in normal industrial use. May be some tissue damage due to frostbite. |
| Eyes | Vapor is no hazard in normal industrial use. May be some tissue damage due to frostbite. High vapor concentrations are irritating to the eyes. |
| First aid | |
| Ingestion | Seek medical assistance. |
| Inhalation | Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. |
| Skin | Remove and isolate contaminated clothing and shoes. Clothing frozen to the skin should be thawed before being removed. In case of contact with liquefied gas, thaw frosted parts with lukewarm water |
| Eyes | Flush with running water for at least 20 minutes. |
