New FAQ for NFPA 704 available for download

Published:  24 March, 2015

The NFPA 704 “diamond” provides a tried and tested method for warning emergency responders of the hazards they could encounter during a spill or fire involving a hazardous material.

The new FAQ on NFPA 704 Standard System for the Identification of the Hazards of Materials for Emergency Response answers questions such as:

  • How does the 704 label differ from other hazardous material labels?
  • When am I required to use the NFPA 704 rating system?
  • Why should I use the NFPA 704 rating system?
  • How is the rating displayed?
  • What other symbols can go in the special hazards quadrant of the "diamond"?
  • Who provides NFPA 704 ratings and can I find those ratings in the Standard?
  • What information on the SDS do I use to rate my hazardous materials?

The FAQ document is now posted and available for download.

Other developments

NFPA has produced a Quick Card (also available to download) that compares OSHA’s HazCom 2012 hazard classification with NFPA 704.

NFPA 704 is currently undergoing revision and the first draft of the document that includes proposed changes for the 2017 edition is now open for public comment.

A few highlighted changes include the addition of the symbol for simple asphyxiant (SA), to be added for liquefied carbon dioxide vapour withdrawal systems and where large quantities of dry ice are used in confined areas,  and the addition of sample placards and explanatory language that can be used in safety publications.  The document is open for public comment through May 15, 2015.
