Maybe this is what everyone is talking about, but it seems that sticking the boron to the tape before you break it would stop the pieces from flying around.

One thing that helps with preventing errant boron scraps is to use a
method of breaking it that is appropriate for the core type you are
using.
Some of our boron filaments are accumulated on carbon fibers; others
are accumulated on tungsten wire.
The carbon core filaments don't like to be bent-to-break. They tend to
shatter in several places, sending bits flying in all directions. A
better way is to crush the filament with a pair of fine-tipped pliers.
Then you just have a little bit of boron dust in the pier's maw that
can be collected with tape. I think I read about that technique in
Harlan's literature somewhere.
The tungsten core filaments don't crush, but fortunately they don't
tend to shatter either. Those can be bent until they snap, and then
you have a bigger piece of scrap to either save or stick on some tape.
