NFPA Hazard Classification Information

The following table provides a listing of chemicals along with their NFPA hazard ratings. Refer to Chapter 1 for a definition of the hazard ratings. The terms W and oxy refer to water reactive and oxidizer, respectively. 

Chemical Name Synonyms Hazard Classification Health (Blue) Flammability (Red) Reactivity (Yellow) Special (White) 

ACETALDEHYDE Acetic Aldehyde, Ethanal, Ethyl Aldehyde Flammable Liquid, I 2 4 2  

ACETIC ACID Glacial Acetic Acid, Ethanoic Acid, Vinegar Acid Corrosive Material, II 2 2 1

Tills subsection provides a listing of selected chemicals, their common synonyms and the listed NFPA (National Fire Protection Association) Hazard Classification for each chemical. Not all chemicals are identified in this table primarily those that an NFPA Hazard Classification could be obtained for, usually from a material safety data sheet (MSDS). The NFPA s "Recommended System for the Identification of Hazards of Materials TNFPA 704) provides basic warning information to fire fighters in industrial plants and storage facilities, as well as traiisponers of hazardous materials. The system Is described in detail in Section 3 of Chapter 1, and also In... 

WHMIS is Workplace Hazardous Material Information System. View explanation of numerical symbols In NFPA classification. 

FPN No. 1) For additional information on the properties and group classification of Class I materials, see Manual for Classification of Gases, Vapors, and Dusts for Electrical Equipment in Hazardous (Classified) Locations, NFPA 497M-1991, and Guide to Eire Hazard Properties ofElammable Liquids, Gases, and Volatile Solids, NFPA 325—1994. 

For the processing industries, most process structures fit into the special purpose industrial, high hazard industrial, or open structures classification. See NFPA 101 for more information. 

The Chemical Data Summary Sheet (CDSS) is a part of a larger INEEL Chemical Management System (ICMS) — a computerized tracking system for chemical products, chemicals, or hazardous agents (CPCHA). INEEL developed the CDSS as a tool to aid in hazard identification. Chemical safety experts evaluated every CPCHA at INEEL and developed a CDSS for each. Information on the CDSS includes the National Fire Protection Association (NFPA) diamond a listing of all hazards and a compatibility classification, time-sensitive classification, and building code classification for the identified CPCHA. While the CDSS is not a replacement for an MSDS, it does contain site-specific safety information that cannot be found in an MSDS and that information is presented in a standardized format... 

Hazard rating (NFPA)—Classification system that uses a four-color diamond to communicate health, flammability, reactivity, and specific hazard information for a chemical substance, a numbering system that rates hazards from 0 (lowest) to 4 (highest). 

Hazard identification a process to identify hazards and associated risk to persons, property, and structures and to improve protection from natural and human-caused hazards Hazard Identification and Risk Assessment (HIRA) a process to identify hazards and associated risk to persons, property, and structures and to improve protection from natural and human-caused hazards HIRA serves as a foundation for planning, resource management, capability development, public education, and training and exercises Hazard operability study a structured means of evaluating a complex process to find problems associated with operability or safety of the process Hazard rating (NFPA) classification system that uses a four-color diamond to communicate health, flammability, reactivity, and speciflc hazard information for a chemical substance a numbering system that rates hazards from zero (lowest) to four (highest)...
