Other than from decompression and fire, what other ways has NASA or the Russian space program identified unique ways someone on the ISS could die suddenly, in particular from human error with the technology of the station.

I understand micrometeors and debris from artificial satellites are always a threat, but those wouldn't be caused by an error on the station.

Addendum-A heart attack; choking with piece of food; losing too much blood from a cut of a major artery, are not unique to errors with the technology of the station.
