Fire duty, dragging hoses, carrying hurt men up/down ladders.
All of which I've seen female members of damage control teams perform just fine.
In fact, with three deployments and multiple workups on co-ed ships under my belt, I'm truly hard-pressed to think of any job that can't be performed equally by both both sexes. It's not like sailors are humping 80 lbs rucksacks and sleeping in foxholes.
