Help safeguard personnel and the public from fire risks and hazards with the recognized marking system in the 2022 edition of NFPA 704, Standard System for the Identification of the Hazards of Materials for Emergency Response.

NFPA 704, Standard System for the Identification of the Hazards of Materials for Emergency Response, simplifies determining the degree of health, flammability, and instability hazards of chemicals – it also provides for the recognition of water reactivity and oxidizers.

The NFPA® “hazard diamond” provides an immediate general sense of the hazards of a material and the severity of these hazards as they relate to emergency response. This simple, readily recognized system of markings is based on NFPA 704.

Professionals utilize this system to:

  • Supply appropriate signals and vital information to protect the public and private emergency response personnel
  • Help plan for efficient fire and emergency control operations
  • Aid designated personnel, engineers, and plant and safety personnel in assessing hazards

This standard is essential for manufacturers and users of hazardous chemicals, emergency responders, AHJs, building designers and inspectors, and consultants specializing in hazard identification and mitigation.

In the 2017 edition of NFPA 704, Annex G was added to explain the key differences between OSHA HazCom2017 and NFPA 704. The new annex clarified why the NFPA 704 rating system would remain unchanged by the implementation of HazCom2017.

The 2022 edition of the standard includes revisions to Figure 9.1(b) and Figure 9.1(c) that provide guidance on NFPA 704 placards, numeral dimensions, and size requirements.

Stay up to date and help keep workers safe from fire hazards and explosions by ordering the 2022 edition of NFPA 704, Standard System for the Identification of the Hazards of Materials for Emergency Response. (Print, 36 pp., 2022)

NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response provides updates plus a new Annex concerning OSHA HazCom2017. Stay up-to-date with the 2017 edition.

The NFPA® “hazard diamond” provides an immediate general sense of the hazards of a material and the severity of these hazards as they relate to emergency response. This simple, readily recognized, and easily understood system of markings is based on NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response. NFPA 704 simplifies determining the degree of health, flammability, and instability hazards of chemicals, and also provides for the recognition of water reactivity and oxidizers.

The 2017 edition of NFPA 704 includes updates and an important clarification related to OSHA HazCom2017:

  • Revised Chapter 8 now requires the use of the SA symbol (representing a simple asphyxiant gas) for liquefied carbon dioxide vapor withdrawal systems and where large quantities of dry ice are used in confined areas. Previous editions of NFPA 704 provided no way of warning of this hazard.
  • New Annex G explains key differences between the OSHA HazCom2017 and NFPA 704 and clarifies the reasons why the NFPA 704 rating system will remain unchanged by the implementation of HazCom2017.
  • New Annex H provides sample placards and verbiage that can be extracted into emergency response publications and training materials to ensure consistency.

The latest NFPA 704 is essential for manufacturers and users of hazardous chemicals, emergency responders, AHJs, building designers and inspectors, and consultants specializing in hazard identification and mitigation.

Make sure critical hazard ratings are accurate and easily understood with NFPA 704.

Displayed in markings commonly referred to as the “NFPA® hazard diamond,” NFPA 704 ratings are based on NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response, the system that simplifies determining the degree of health, flammability, and instability hazards of chemicals. NFPA 704 also provides for the recognition of water reactivity and oxidizers.

This 2012 edition helps users work more accurately with:

  • New guidance on the flammability hazard classification for aerosol products in Table 6.2.
  • New text in Table 6.2 emphasizing the use of Annex D to classify the flammability hazard of a finely-divided solid
  • Differential scanning calorimetry (DSC) hazard criteria reinstated to Table 7.2.

Changes make this edition of NFPA 704 essential for manufacturers and users of hazardous chemicals, emergency responders to such facilities, and consultants specializing in hazard identification and mitigation.
