Human ingestion on large turbofans is surprisingly rare - last number I saw was something like once every ten years, worldwide. So I'd be a bit surprised if there is an established protocol for something that happens so rarely (and it's not like the cause of death is in question).
Interestingly, ingestion events were far more common with the low bypass fans (e.g. JT8D) - there used to be more than one a year (although not always fatal since there were inlet guide vanes that kept them out of the fan). Apparently those big fans make people wary enough that they stay well clear?
