I don’t really know if this has been discussed, but if you’re
using Potassiumferricyanide (sp?) for bleaching, make sure that you don’t
use it near stop-bath. The chemicals in the stop-bath has an agent that
releases cyanide gas if it is mixed with PFC.

Subject: Re: Darkroom question...
Many thanks to those that answered my question on
bleaching.
The information, comments and warnings is extremely useful and confirms my
expectation that this is going to be a very delicate process. But, the
fact of the matter is that unless I somehow treat these single-copy prints,
they will remain of limited value.
I have now found a darkroom here in Montreal that has a sink big enough for me
to lay the prints flat, so that I will have a much better control of the
process than with the roll-unroll-reroll process. And I will have the
assistance of someone who has quite a big of experience with selective
bleaching.
Wish me luck...
Guy
