To make complex and technical scenarios quickly and easily understood, SEL offers a number of options in the development of Demonstrative Evidence. These include:

____• Animation

____• Computer-generated graphics

____• Three-dimensional scale models

____• Video-taping of a reconstructed full-scale scenario

____• Closed circuit television for a walk-through of simulated sites _____and scenes

____• Large-format engineering art and layouts

Over the past few years, this process has been used by SEL, not just for illustrating an event, but also for assisting in researching and analyzing elements of a fire or explosion. The path of explosive vapors from source to ignition have been calculated and illustrated, and the most likely scenario for the development of a fire from an ignition source has been determined.
