George,

The use of Polystyrene 'balls' is common in cavity fill even today - but
fibre fill is gaining popularity/

If your house cavities have been filled for a while with 'balls' and there
are no damp patches at various spots on the internal walls, don't worry,
there are no problems.

Is it flammable - yes. But its unlikely to catch fire in a cavity wall!

Does soemthing nasty to electric wires - no. And its not a normal practice
to run cables in the cavity.

What else - If its polystyrene balls, then they just go everywhere if you
have to cut into the cavity.
If it's the old Styrene injected foam, then that did
cause problems with fumes -
But its unlikely that you'll have that.

Hope this helps?
