An Assessment Of The Use Of Structural Deformation As A Method Of Determining Area Of Fire Origin, Andrew T. Tinsley, David J. Icove

Safety, Security and Emergency Management Faculty and Staff Scholarship

Current methodologies of origin investigation have yet to include the structural deformations seen in steel buildings as a viable indicator of the area of origin of a given fire. As many steel structures are of relatively large size, it is often difficult to determine the area of origin using the typical dig and sift methods advocated in NFPA 921, especially if the extent of the fire was large and there were no witnesses as to the origin of the fire. As has been investigated for years, the performance of steel is highly affected by the application of heat. The science …
