Storey,

The toroid is normally high enough above the primary winding that this
usually doesn't present a problem.  Most of the primary coupling will
occur in the bottom half or so of the secondary. Of more importance is
to make sure that any strikerail above the primary isn't a shorted turn.

Safe coilin' to ya!
