It should be stored away from clothing and other combustible materials, and valves and fittings must be kept free from grease and oil. Users should avoid inhaling the gas and prevent contact with eyes, skin, or clothing. Nitrous Oxide should only be used and stored outdoors or in well-ventilated areas. Protective gloves, clothing, and either eye or face protection are strongly recommended.

In the event of a fire, it is crucial to stop the leak if it is safe to do so. The gas should be stored securely and disposed of in accordance with the supplier's instructions. A backflow preventive device should be utilized in the piping, and valves must be closed after each use and when empty. Only equipment made from compatible materials should be used, and valves should be opened slowly. Equipment must be cleaned for oxygen service, and the gas should be protected from sunlight when ambient temperatures exceed 52°C (125°F). It is essential to read and follow the Safety Data Sheet (SDS) prior to use.

First Aid Measures In case of inhalation, the affected individual should be moved to fresh air and kept comfortable for breathing. If the person feels unwell, a poison center or physician should be contacted.
