I'm not exactly sure what "Dead" means in Rayfire, since it's not a PhysX term....however, you can also do a property test on your particles (test if sleeping, test if velocity is below a certain value, etc) and send them to an event with a PhysX switch operator to make them kinematic. Kinematic = can collide against other particles but will never move.
