What we have here is your basic fire hazard. Cooling water is injected into the aft section of this exhaust riser (where the hose is), however between that point and the engine, it’s essentially a dry exhaust and gets extremely hot. This section of the riser should be wrapped with a suitable insulating material to prevent burns and protect equipment (such as the hose resting on it). Look closely and you’ll also notice that there are no stainless steel clamps holding the exhaust hose onto the riser.
