Short title	Horizontal stop holds fire while vertical tray fire jumps the stop and continues.
Image title	Schematic of the Waterford 3 incident. Left: a horizontal cable tray with a firestop; the fire on one side is held at the stop. Right: a vertical cable tray with a firestop; the fire jumps over the stop and continues to propagate upward. Whether the vertical stop delayed propagation is uncertain. A note says this is one incident, not a general failure rate.
