Re: Darkroom hazards, was Levels & Curves



Hi Art,

Years ago I used to use a "desktop" b & w two chemical processor for short
lived prints to be used in magazines I did photography for. I had news
papers and at one time aluminum foil under the machine to catch some of the
spills. I was told later that the chemicals mixing with the foil could cause
a dangerous gas. I think it was cyanide gas but not for sure, but I know
they said it could do some bad harm.

| As someone else mentioned, some smokers live to a ripe old age, that, in
| itself, doesn't prove that smoking is safe.
|
| I don't think anyone in their right mind would suggest sepia toners with
| their hydrogen sulfide gas output, or mercury or chromium based negative
| intensifiers are safe to use without extreme care, or selenium toners,
| or cyanide based bleaches, yet this was commonplace in the early years
| of my darkroom work.  It is easy to refer to those who give us early
| warning of hazards as "eco-freaks" but history usually bears those early
| warnings out.
|
| Much of the problem with determining hazards with chemical contact is
| that it is a slow insidious process, often only obvious after years of
| contact, and manifested in later years of life.  Genetics and other
| factors enter into how people respond.  Asthma levels are up 10 fold
| among children, and perhaps indeed it is due to our more sterile
| environment and over active immune response, but regardless, they are
| more vulnerable to chemical respiratory sensitivities as a result.
|
| My own "profession photographer" experience simply bears out the
| concerns.  I have developed a severe, life-threatening sulfite
| sensitivity.  I cannot with 100% surety claim it was due to darkroom
| work, but that was certainly my main contact with sulfites.  I know of
| several other photographers this has happened to.
