NFPA 59A-2019 PDF Download

The NFPA 59A-2019 standard is a vital document that aims to identify and mitigate risks associated with LNG plants and export facilities. The standard has been adopted by the Department of Transportation (DOT) and is referenced by other agencies such as the Federal Energy Regulatory Commission. Its guidelines govern the selection of sites, design, construction, and fire protection measures for LNG plants.

NFPA 59A is not only required throughout the United States but is also internationally recognized as the go-to standard for safety in these specialized facilities. The standard provides prescriptive requirements, as well as a performance-based option, which involves analyzing the risks to individuals and property surrounding the proposed LNG plant and incorporating risk mitigation techniques into the facility design.

With the increasing prevalence of LNG in the United States, the country has evolved from being primarily an LNG importer to a major LNG exporter. As a result, many LNG export facilities under development rely on NFPA 59A for guidance on LNG production, storage, and handling.

The latest edition of NFPA 59A includes several significant updates. The requirements for plant siting and layout have been reorganized to enhance focus and ease of implementation. Additionally, a new chapter, Chapter 17, has been introduced, which specifically addresses the requirements for stationary applications in small-scale LNG facilities, utilizing ASME containers. This chapter also establishes a framework for the safe implementation of single-wall ASME containers with supplementary design and fabrication requirements for storage in small-scale LNG facilities. Furthermore, provisions regarding security and personnel training, once found in annexes, are now incorporated into the mandatory requirements.
