42 FIRE INVESTIGATION CHANGE AND EVOLUTION, PART 1: AN OVERVIEW The field of fire investigation is in a period of rebirth, the result of a new understanding of fire behavior, new technolog, and proaction by the investigation community. This is the first of a series of articles that will separate fact from fiction and document important findings and trends, with special emphasis on the new NFPA investigation standard. James H. Sbanley, Jr.

59 CRYOGENIC LIQUID OXYGEN CONTAINER EXPLOSION: AN INVESTIGATION While high-pressure gas/liquid containers are designed with safety features to limit the potential for catastrophic failure, human error makes such failure a real possibility. An effective post-blast investigation is vital to supporting code enforcement efforts to prevent such accidents.
Frank P. Woodward, Larry E. Hansen, and Douglas A. Mellon
65 MAINTAINING FIRE SCENE SECURITY FOR HIGH-RISE INVESTIGATIONS The fire department will play an integral role in securing a high-rise building during the salvage and overhaul/fire investigation phase. Efficient preplanning will allow you to establish the building access team quickly and display to building owners and occupants, local officials, insurance companies, the legal community, and others that your department can effectively manage a fire scene before and after the flames are extinguished.
