How do I capture Ancient Danger Pawns safely?

I am surprised to not find any post on capturing the pawns cryosleep in ancient danger pods safely.

I have unlocked them quite few times and mostly there are hostile with rifles and armor so what are the effective ways of capturing them with minimal damage.

1 - Spike Traps Passage outside the walls I have tried this but they just simply die and if they don't they just keep walking to another spike trap to die.

2 - Heating the room extremely with campfires

My base is kinda starter base I don't have access to firearms yet coz tribal start

Dealing with flesh beasts and mechanitoids is easy just long spike passage. Otherwise call the yeoman ceremony

Any ideas?
