My mother lost her sense of smell after surgery for nasal polyps in her teens. She was mortally afraid of fire breaking out in the night and not being able to smell it.

Maybe not reassuring at all: but we can't smell a lot while we are asleep. A bad smell won't wake us up. That's why fire alarms exist, noise (or bright light) does wake us up.
