Purpose

Purpose The Mississippi Legislature’s passage of Senate Bill 2787 (2026) created a requirement that each school facility “shall perform an annual pressure test on the liquefied petroleum gas piping system in the school facility.” The terminology of “pressure test” holds a specific meaning in the liquefied compressed gas industry, meaning a testing process described in detail in National Fire Protection Association (NFPA) 54, Chapter 8 (2024). Senate Bill 2787 further provides a description of the requirements for the testing process, requiring that the “testing shall be sufficient to determine whether the liquefied petroleum gas piping downstream of the school facility’s liquefied petroleum gas tank holds at least normal operating pressure over a specified period determined by the applicable codes, rules and regulations,” which is a testing process commonly referred to in the liquefied compressed gas industry and NFPA codes as a “leak check”. A “pressure test” and a “leak check” are two distinct processes for use in different circumstances pursuant to the provisions of NFPA 54. The purpose of this Regulation is to clarify the appropriate annual testing process relative to ensuring the integrity of a school system’s liquefied petroleum gas piping system in compliance with the provisions in the National Fire Protection Association (NFPA) Liquefied Petroleum Gas Codes and Senate Bill 2787 (2026).
