Alcohol Interaction?
Ammonia-Bleach is the creation of chloramine and or
hydrazine which are toxic and explosive
Bleach-Acid releases the chlorine gas
Bleach-Alcohol could generate some chlorethane which is
quite explosive...but I believe it should not be a problem
in low concentrations.
I think all this stuff is so diluted that it would not
cause any problems. Bleach destroys hypo so is good for
removing crystallized hypo residue on equipment. However,
usually a hot water wash will clean tanks and trays
sufficiently. Its only when hypo is left in containers for
very long periods of time that it can cause problems.
At one time chlorine was the most common substance used
to kill bacteria in water. These days chloramines seem to
be more often used. I don't think either will affect
photographic chemicals and chlorine is destroyed by hypo.
However, if you boil water to purify it beware that boiling
does not remove chloramines. An activated charcoal filter,
like a Brita filter, will remove it. Boiling drives off
dissolved gasses so it will generally remove plain chlorine
and will drive off dissolved air.
Probably the most hazardous chemicals most people
encounter is the stuff under the kitchen sink.
