In this morning’s traffic roundup, we briefly mentioned SFD units blocking part of Harbor Avenue because of a medical response at Seacrest. Though the callout was not listed as a water rescue, we later learned from readers in the area that the person who was treated by SFD medics had been diving. Dispatch audio indicated he was unconscious when brought out of the water around 9 am. Radio exchanges also indicated that he would be taken to Virginia Mason Hospital, which has a hyperbaric chamber. Seattle Fire spokesperson David Cuerpo tells WSB that the 63-year-old man was assessed as being in critical condition when transported to VM.
