2011 Version of NFPA-780:
A Quick Overview of Changes from Earlier Versions
Some highlights are summarized below:
Chapter 4, "Protection for Ordinary Structures," is clarified and has new details on air terminals, bonding, stand-off calculations, grounding, and surge protection.
Chapter 8, "Explosives Storage," is 100% re-written. Note to military readers: These details exceed many military codes. Protection methods specified in this chapter may be applied elsewhere by "authorities having jurisdiction" (AHJs).
Annex A, "Explanatory Material," is a must-read section. See page 38, Figure A.4.7.4.1, for an illustration of the Rolling Sphere Method.
Annex L, "Risk Management," is a total re-write.
Annex M, "Personal Safety," contains much new information. This is the ONLY section where personal safety is discussed/ don’t look for any such information in Chapter 4 or elsewhere.
Thanks to the 780 Technical Committee under John Tobias’ leadership for an excellent result in this new version of the standard.
