Nitrous oxide

Nitrous oxide is a type of gas. It is used in surgery as an anesthetic. The gas is stored in tanks supported by a rolling stand. Gauges on the stand monitor the amount of gas being applied through a gas mask. Nitrous oxide can be very dangerous if mishandled. This is why tanks of the gas are labeled with warning signs.

Vault-Tec supplied tanks of this gas to the Vaults prior to the Great War of 2077. These tanks are painted green and carry warning labels.

In Vault 101, two of these tanks are seen in the Clinic attached to a rolling stand.
