Based on the latest information from the field, NFPA 400, Hazardous Materials Code is your source for specialized knowledge that helps protect workers, communities, and emergency responders.
Unsafe storage, handling, and use of hazardous materials can result in serious incidents including loss of life and millions of dollars in property damage. NFPA 400, Hazardous Materials Code provides the newest safety information for any facility or occupancy that stores, handles, or uses one or more of the covered classes of hazardous materials.
NFPA 400 consolidates requirements on oxidizers, organic peroxides, pesticides, and ammonium nitrate based on requirements from previous stand-alone documents: NFPA 430, NFPA 432, NFPA 434, and NFPA 490, respectively. It also includes requirements for materials that are classified as unstable/reactives, water reactives, corrosives, pyrophoric, toxic and highly toxic, and flammable solids.
Additional changes to Chapter 11: Ammonium Nitrate are especially important for fertilizer storage facilities.
Continuing updates made in the previous edition, Chapter 11 in the 2019 edition has been revised to facilitate a higher level of safety and compliance. Added text clarifies which sections apply retroactively, and clarifies that molten ammonium nitrate needs to be able to flow away from storage areas to open, unconfined areas free from incompatible materials. Revised fire protection system requirements specify that automatic fire sprinkler systems are not required in Type I or Type II construction buildings unless they also have combustible content. New requirements for ammonium nitrate storage in railcars address non–transportation-regulated storage.
