Which agency provides standards and safety regulations for gas tanks and cylinders?

The Compressed Gas Association is the agency that specifically focuses on the standards and safety regulations for gas tanks and cylinders. This organization develops guidelines, best practices, and safety standards that pertain to the manufacture, transportation, storage, and use of compressed gases. Their work is vital in ensuring safe handling and preventing accidents related to gas cylinders, which can be hazardous if not properly managed.

The other agencies mentioned serve different functions: the Food and Drug Administration primarily oversees food and pharmaceutical safety, the National Fire Prevention Agency focuses on fire prevention and safety in general, and the Occupational Safety and Health Administration is involved with workplace safety and health regulations across various industries. While each of these agencies may have some overlap in dealing with issues related to safety, the Compressed Gas Association is the most specifically aligned with the standards for gas tanks and cylinders.
