Dangerous place to expose tip (10)
I believe the answer is:
flashpoint
'dangerous place' is the definition.
'expose tip' is the wordplay.
'expose' becomes 'flash' (flashing is a kind of exposing**).
'tip' becomes 'point' ('point' can be a synonym of 'tip').
'flash'+'point'='FLASHPOINT'
'to' is the link.
(Other definitions for flashpoint that I've seen before include "Moment when hostility flares up" , "moment of emergency" .)
