Dave:

I personally think that Ferric Chloride is one of the worst compounds to
have around in a domestic environment, or in any environment that is
not specifically designed to accommodate this material. Most of the
technical descriptions that I have seen regarding this material
describe it as "highly corrosive". It emits fumes even at normal room
temperature.

Muriatic+Peroxide is also corrosive, but not as bad as Ferric Chloride.
Employ measures to protect.
