In Maus, what 3 times does Vladek almost die, but is saved?

Question

I feel like there are a ton of times he could have dies (being in the concentration camps alone is life-threatening enough), but I'm not sure what specific times Vladek was really close to death, but was saved?

If anyone could help me out. Maybe give me a chapter or a general idea of where I could find specific examples of this, I would really appreciate it.

THANK YOU SO MUCH!!
