What is NFPA 59A?
NFPA 59A: Document Scope

1.1* Scope. A.1.1 This standard establishes essential requirements and standards for the design, installation, and safe operation of liquefied natural gas (LNG) facilities. It provides guidance to all persons concerned with the construction and operation equipment for the production, storage, and handling of LNG. It is not a design handbook, and competent engineering judgment is necessary for its proper use. At sufficiently low temperatures, natural gas liquefies. At atmospheric pressure, natural gas can be liquefied by reducing its temperature to approximately 260°F (162°C). Upon release from the container to the atmosphere, LNG will vaporize and release gas that, at ambient temperature, has about 600 times the volume of the liquid. Generally, at temperatures below approximately 170°F (112°C), the gas is heavier than ambient air at 60°F (15.6°C). However, as its temperature rises, it becomes lighter than air. Note that the 260°F (162°C) temperature value is for methane. If the other constituents are present, see 3.3.15. For information on the use of LNG as a vehicle fuel, see NFPA 52, Vehicular Gaseous Fuel Systems Code. 1.1.1 This standard shall apply to the following: (1) Facilities that liquefy natural gas (2) Facilities that store, vaporize, transfer, and handle liquefied natural gas (LNG) (3) The training of all personnel involved with LNG (4) The design, location, construction, maintenance, and operation of all LNG facilities 1.1.2 This standard shall not apply to the following: (1) Frozen ground containers (2) Portable storage containers stored or used in buildings (3) All LNG vehicular applications, including fueling of LNG vehicles

This standard provides minimum fire protection, safety, and related requirements for the location, design, construction, security, operation, and maintenance of liquefied natural gas (LNG) plants.

Official document scope
What does NFPA 59A address?

Provisions apply to (1) facilities that liquefy natural gas, (2) facilities that store, vaporize, transfer, and handle liquefied natural gas, (3) the training of all personnel involved with LNG, and (4) the design, location, construction, maintenance, and operation of all LNG facilities. Among specific topics covered are process equipment; stationary LNG storage; vaporization facilities; piping systems and components; instrumentation and electrical services; transfer systems; fire protection, safety, and security; stationary applications using ASME containers; and performance-based LNG plant siting.
