| [Fire Fighting] Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Do not use water on material itself. Apply water from as far a distance as possible. | |
| [Fire Potential] Non-flammable gas. | |
| [Ingestion] Seek medical assistance. | |
| [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. | |
| [Skin] Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. | |
| [Eyes] Immediately flush with running water for at least 20 minutes. | |
| [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. | |
| [Inhalation] Vapors may cause dizziness or asphyxiation without warning. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. | |
| [Skin] Contact with liquid may cause frostbite. | |
| [Eyes] Pain. Blurred vision. Severe deep burns. | |
| [Ingestion] Not likely to be a routed of exposure. | |
| [Hazards] Containers may explode when heated. Ruptured cylinders may rocket. | |
| [UN (DOT)] 1951 | |
| [Personal 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). | |
| [Exposure Effects] The toxological properties of this substance have not been fully investigated. | |
