Kinda like when a swimmer is drowning ,the person jumps in to help and they both drown . Look up Confined Space procedure or deaths .
Deaths have occurred in the fish holds of fishing boats, has lead to multiple deaths, first guy goes down and looses consciousness and then another guy jumps in to help and the same thing happens.
A good friend of mine had this happen to him on a tanker ship, didn't follow protocol and almost died.
