NFPA (National Fire Protection Association) 921, which is the National Standard for Fire and Explosion Investigations, very clearly indicates in numerous sections that the possibility of explosives should have been thoroughly investigated. Specifically in NFPA 921 18.3.2
High Order Damage -
“High-order damage is characterized by shattering of the structure, producing small, pulverized debris. Walls, roofs, and structural members are splintered or shattered, with the building completely demolished. Debris is thrown great distances, possibly hundreds of feet. High-order damage is the result of rapid rates of pressure rise.” World Trade Center’s 1, 2, and 7 all clearly met this definition; therefore they should have been thoroughly investigated and analyzed for explosives. Specifically, the use of “exotic accelerants” should have been investigated. In NFPA 921 19.2.4
-”Exotic Accelerants,” three indicators were clearly met that should have led to a thorough investigation in to the possible use of “exotic accelerants,” specifically as stated in the guideline, “Thermite mixtures.”
So, why was the possibility of explosives, controlled demolition, or the use of “exotic accelerants” not thoroughly investigated, or even mentioned in the 9-11 Commission Report?
