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.
