Quarry place sealed vault to avoid risks (4,2,4)

'avoid risks' is the definition.
I know nothing about this answer so I can't tell whether this works.

'quarry place sealed vault' is the wordplay.
I cannot really see how this works, but
'place' could be 'lay' (laying is a kind of placing) and 'lay' is found in the answer.
'quarry' could be 'pit' (synonyms) and 'pit' is found in the remaining letters.
'vault' could be 'safe' (I've seen this in another clue) and 'safe' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

'to' acts as a link.

Can you help me to learn more?
