NFPA 921, 1033 and 1321 are three documents that effect the fire and explosion investigation industry as a whole.  Revisions to these documents occur on a pre-determined timeframe.  The Missouri Chapter of the International Association of Arson Investigators stays up to date on each document and their revisions.  It is our goal to make sure that our members stay up to date as well.  Revision cycles and public comment dates will be posted on this page when prior to the public comment time frame along with links to the NFPA's page for each document.
