Kodak Reintroduces Ektachrome.

[AgX]

Disposal of the relicts of a facilty is something else than building or running a facility. And disposal of chemical waste and its cost is related to any chemical facility producing waste.

The Ilfochrome chemistry is quite bad compared to RA4 or C41 or even E6 (but that is only a bit worse due to the greater number of chemicals).

How would you rate it compared to Pyrogallol and Ammonium Bichromate, both still sold by Formulary and used in much higher quantities than the quinoxaline compound in dye bleach ?

 

[Photo Engineer]

Rudi, none of them are good for you, but the DB catalysts are known to be carcinogens. There are a number of them BTW, and Ciba used several.

I have used all 3, but only reluctantly. I do not have the Pyrogallol, but I did use some Bichromates on and off for a variety of tasks.

[Poisson Du Jour]

Squamous- and basal-cell carninomas wear a regular feature on the hands of the head printer of Ilfochrome Classic; he also had emphysema and visual disturbances. None of us saw or heard of him again after 2012.

 

[Rudeofus]

Dye bleach contains significant amounts of Sulfuric Acid, which makes it unlikely that anyone getting in contact with it would not immediately wash it off. How did your printer get in contact with this soup ?

 

[Photo Engineer]

Rudi, this can happen accidentally just by getting an unnoticed splash. But some of the catalysts are volatile and some were coated in the print material and some were in the developer. The products varied.

I realize that splashes happen, and many people would tend to ignore splashes of stop bath, BLIX or fixer for a while before washing them off. But splashes of dye bleach are entirely different, apart from all carcinogenic ingredients this one is loaded with Sulfuric Acid, which is next to impossible to ignore. I can not imagine anyone who would not immediately wash that off.

But I guess my theory is one thing, and practical experience is often very different :-/

 

[Photo Engineer]

Rudi, you are right in one way, but how many people know chemistry. I've seen and heard of some pretty outrageous behavior in the DR by those who have no knowledge of the chemistry that is around them.

People are pretty quick at learning chemistry when they have 5% Sulfuric Acid on their skin. This isn't something one can ignore. No way people wouldn't wash this off at once, even if they had no idea about the dangers of Quinoxaline.

 

[Photo Engineer]

We had a young lady spill conc H2SO4 on herself in lab and not say anything about it. When her dress began dissolving, the instructor grabbed her and put her in a lab sink with running water on her, and someone called an ambulance. Her explanation... she was afraid to report it, didn't know the consequences (in spite of our warnings beforehand), and then she went totally off the wall and panicked when her clothing began to dissolve. I was in the upstairs lab and only had a peripheral view of all of this, but my good friend Fred was the instructor.

Who has to licence what at cost at EPA? EPA is a US authority, not a german one.

Maybe you mean paying for installing safety devices to comply with a authority standards. But over here these would not be different from those concerning more standard photo-chemicals.

.......if we would just talk about bw film reversal ? There have been some developing sets from Orwo within the past. From an invironmental perspective it wasn,t so much strange (in the past).
But to handle that stuff with care was a question to survive in your dark room.
Cibachrome is in comparison indeed its own class.
PE is obviously best involved with that what he stated. I didn't would tell there are issues where this isn't the case. (generaly).

But then it is allways too late isn't it?

PS : The pannic tool in darkroom is a kanister Kodak Xtol (mixed in max.delution)

 

[trendland]

Probably a different name in Germany and elsewhere. I was referring to the Australian Environment Protection Authority and the $38,000 licencing that was levied for disposal of hazardous chemical waste at the old Ilfochrome Classic printing facility, along with odour and noise abatement for a place that was surrounded on all sides by residential housing. The lab was demolished early in May 2011, and a very nice set of modern town houses built on the site. Residents nearby were not sorry at all to see the lab close which was soon after discontinuation of Ilfochrome Classic as a print media.

By the way : Robin Williams as "Symor Parrish" made his own experience with accidental lab chems in
"One hour Photo" LOOK :

Handle lab chems better with extreme care friends !

Trendland, I got no idea in what way your post above quoting mine is related to my post.

I've noticed that as well. Enthusiasm !

If I understood this theme here right it goes about the danger of chemicals in concern of discontinued processes - cibachrome for example.
What I intended to cover out is the relation of danger. If we just remember bw reversal processes -
(Agfa Scala was also one of the last) we found out that from environmental issues and from concerns of healthy in darkroom there is a realy difference to normal bw developing (PE metioned bleach substances of some color reversal processes).
The simular (of course bw related - therefore different substances) are the problem in bw reversal.
And the issue of discontinued color processes from the past is to me that you have an other class of danger there.
The simple opposite are modern bw processes. Here substances from the past are not longer in use because Kodak/Ilford reformulated their main formulas.
So we are most talking about to avoid methol in bw processing today. As one of the last chemicals
regulators will have it on their scedule next.
Kodak Xtol I simply intended to mention as an example for people in overdriven fear about bw chemicals.
So in short again : The relation of possible trouble with different "classes" of chems used in darkroom could be immense.
Perhaps I missunderstood your post Agx and you have just stated it in concerning of regulation of chems in different countrys - I now have an Idea of ???

So far the substances banned endangered much less the processor or even the consumer, but the people in the film plants and its environment.
On the other hand at these places chances for protection and recovery, meanwhile, are greatest. So one may argue on such restrictions.

Tackling critical processing chemicals at least for amateur use would be another issue. But seen the upset already about classic materials having gone or being reformulated with resulting different characteristics this likely would induce even more critic.

I wonder if EK will market the film in 35mm format for this purpose:

Eastman Kodak explicitely stated that the 35mm film will be the still film version.

Must be getting close to real, theer is a data sheet at
