According to regulations, what is the minimum capacity of a portable tank?

The minimum capacity of a portable tank for medical gas storage is set at 60 gallons according to the relevant regulations. This requirement ensures that the tanks are sufficiently large to handle the typical volume of gases used in medical settings while maintaining a manageable size for transport and use. A capacity of 60 gallons strikes a balance between providing enough gas for operational needs and ensuring that the tank remains portable and safe to handle. Regulations are developed with safety, usability, and efficiency in mind to prevent potential hazards associated with larger or smaller tanks.
