This past weekend races there was a bad wreck, brake failure @ over 100 mph, so as you plan your fire suppression system make sure you have enough suppression at the point of exit from the car, also make sure there is a external kill switch that is available for corner workers and also a remote fire pull. The driver here did not kill his fuel pump and also did not pull the fire suppression and neither one was available to the corner workers to activate. I'm also not sure how folks are wiring their fuel pumps but an inertia switch or some other means is recommended.
