An explosive decompression accident

Four divers in a compression chamber system were suddenly decompressed from 9 atm to 1 atm. One of the divers was about to close the door between the chamber system and the trunk when the accident happened. He was shot out through the door and severely mutilated. The three others died on the spot. The autopsy results are described. The most conspicuous finding was large amounts of fat in the large arteries and veins and in the cardiac chambers, as well as intravascular fat in the organs, especially the liver. This fat can hardly have been embolic, but must have "dropped out" of the blood in situ. It is suggested that the boiling of the blood denatured the lipoprotein complexes, rendering the lipids insoluble.
