The new 2014 edition of NFPA 921 Guide For Fire and Explosion Investigation is available. NFPA 921 is the premier document in the world today that provides guidance and recommendations as to the proper methodology to follow and the science to apply to the investigation of fire and explosion incidents.
The 2014 edition is the first NFPA Code or Standard document to be published in color. The Technical Committee Chairman Randy Watson has been working with the Committee and NFPA to incorporate color photographs into the document. This will greatly enhance the effectiveness of the document, and no chapter will exemplify this change more than in fire patterns. Now, the contrast and color changes will be much more clearly visible.
A new chapter on Fire Protection Systems was also added that addresses key components, operational and installation parameters, data gathering and analysis of active fire protection systems. The chapter on Analyzing the Incident for Cause and Responsibility has been divided into two chapters and the classification of fire causes is in one chapter and the responsibility discussion is in a separate chapter.
There has been a lot of research and testing over the last few years on Electrical Arcing, as a result of this new research, the committee added information and photographs to better explain and demonstrate the concepts.
The PDF version of NFPA 921 is available now through the NFPA catalog and the hard copy of NFPA 921 will be available early to mid-February 2014.
