I seem to remember the EU getting involved in tanalising a few years
ago (20000/2001 ?) and that the old ( traditional) tanalising
involving heavy metals (copper, chromium and arsenic) had been banned.

The replacement stuff, (copper triazol ?) is supposedly less toxic to
touchy/feely children chewing upon it.
I dont know how it reacts in a fire !
But dioxins from all the other stuff are perhaps more pertinent if one
wants to worry onself to death !

All off top of head, caveat emptor ,,
