Which organization establishes the design standards for LP-Gas storage containers?

The organization that establishes the design standards for LP-Gas storage containers is the American Society of Mechanical Engineers (ASME). ASME is responsible for the development of codes and standards that ensure the safe design, construction, and maintenance of pressure vessels and storage systems, including those used for liquefied petroleum gas (LP-Gas). Their standards are widely adopted and recognized in the industry, ensuring that vessels operate safely under the pressures and conditions associated with LP-Gas.

In contrast, while the National Fire Protection Association (NFPA) provides guidelines related to fire safety and may incorporate aspects concerning LP-Gas storage, it does not specifically set the design standards for storage containers. The Occupational Safety and Health Administration (OSHA) focuses on workplace safety regulations and may enforce safe practices when handling LP-Gas but does not deal directly with design standards. Underwriters Laboratories (UL) is involved in testing products for safety but does not set the foundational design codes for storage containers in the same manner as ASME. Thus, ASME stands out as the authoritative body for establishing these crucial design standards for LP-Gas storage containers.
