Install / Failure Note

Chem Prolok's double-wall containment was specified for the cyanide-bearing waste stream itself at UTC Goodrich, not just the treatment instrumentation around it — a real distinction in scope that matters when a plating-line quote treats containment piping as optional.

Cyanide and ferric chloride sit in the same salts/brines family on paper but come from completely different processes — plating-bath waste and heap-leach raffinate — and the real UTC Goodrich installation confirms double-wall Chem Prolok containment was specified for the cyanide waste stream itself, not treated as an afterthought.
