NFPA 400 is a new code, published in 2010, that consolidates the code from four previous NFPA hazardous materials codes, that were separate documents, into a single document. The old NFPA codes are:
- NFPA 430 Code for the Storage of Liquid and Solid Oxidizers
- NFPA 432 Code for the Storage of Organic Peroxide Formulations
- NFPA 434 Code for the Storage of Pesticides
- NFPA 490 Code for the Storage of Ammonium Nitrate
The new NFPA 400 also includes code to cover additional hazardous material categories in building and fire codes. These include substances such as corrosives, flammable solids, pyrophoric substances, toxic and highly toxic materials, unstable materials and water-reactive materials. NFPA 400 also extracted NFPA 55 into chapter 21 of NFPA 400, providing code covering compressed gases and cryogenic fluids.
NFPA 400 does not apply to explosives, fireworks, combustible metals, liquified petroleum gas, aerosols, and flammable or combustible liquids that have no other hazards. NFPA 400 does not apply to the storage or use of hazardous materials for individual use in one or two family homes. It also does not apply to hazardous materials stored or used in farm buildings, or similar types of buildings, or in remote locations when they are used for agricultural purposes.
NFPA 400 establishes classifications for hazardous materials and sets the threshold quantities that are permitted to be stored without taking protection measures.
According to the NFPA the NFPA 400 code benefits the following types of people:
- Enforcing officials when reviewing permits for occupancies storing, handling or using hazardous materials or when inspecting existing facilities
- Operators of facilities by providing safeguards applicable to facilities working with these types of materials
- The insurance industry by identifying various classifications of hazardous materials and defining fire and life safety protective measures required based upon occupancy and quantity of materials.
Both NFPA 400 and the OSHA Hazard Communication Standard (HCS) require that hazardous materials be labeled. The label printers that get the job done are DuraLabel custom label printers. DuraLabel is the only brand that has over 50 types of labeling supplies available. That means you can always get the right supply for the job. Plus DuraLabel printers and supplies make creating hazardous materials labels fast and easy.
