New fact sheet highlights updates to NFPA 30

NFPA 30 Fact SheetIn January, NFPA released the 2021 edition of NFPA 30 Flammable and Combustible Liquids Code which includes changes to the nomenclature used throughout the code and revised sections addressing warehouse and tank storage, as well as piping. To highlight some of these changes, a new fact sheet has been developed.

Changes in Terminology

The nomenclature adjustments were made to reduce the confusion caused by various governmental definitions by emphasizing the existing liquid classifications tied to ignitible liquid properties. Changes will also help to reduce the perception that fires involving combustible liquids pose lesser fire hazards than those involving flammable liquids.

Changes to Storage Requirements

The code now reflects updated storage requirements of ignitable (flammable and combustible) liquids, based on the results of recent fire testing.  The application of NFPA 30 container requirements apply to any consumer product containing water-miscible ignitable liquids that are greater than 20 percent by volume ignitable liquids instead of greater than 50 percent by volume. Also included are six new storage designs for containers storing all classes other than Class IA (IB, IC, II, IIIA, IIIB). Storage options for protected general-purpose warehouses are also reflected in the updated code.

NFPA 30 is now available in NFPA LiNK™ - the association’s new information delivery platform with NFPA codes and standards, supplementary content, and visual aids for building, electrical, and life safety professionals and practitioners.
