NFPA 59A PDF

Highlights

Required throughout the US and trusted internationally, the 2023 edition of NFPA 59A features extensive revisions to make the standard easier to use and up to date with the industry.
Key changes include:
Added minimum required records reflecting the current design of the facility to serve as the basis for an engineering review of change
Standardized the use of the terms hazardous fluid and ignitible fluid throughout the document to reflect the hazard of concern in regards to the requirement
Added requirements for fire and gas detectors to be located in accordance with a documented performance-based analysis to provide a more consistent design approach for these devices in the LNG industry
Revisions added to clarify which requirements apply to facilities when in-kind replacements are made to encourage maintainability, reliability, and safety at LNG facilities
Updated release probabilities and conditional probabilities in Chapter 19 to reflect new data for failure rates and also reflect specific hole sizes of various leaks
