 |
|
Kolb Friends –
We all use AN hardware for building our airplanes.
Just this week, I learned that Cadmium is highly toxic. Common sources categorize it as an “extremely toxic heavy metal,” with very low permissible exposure limits. In fact, the US Government issued a directive in 2007 that forbids the use of any product containing Cadmium for any new systems being developed. (I wonder what the Air Force uses to hold the F-22 together?)
This is probably related to the fact that sales of NiCad rechargeable batteries are now greatly restricted.
Yikes! I feel like I’ve been living in a fish bowl all these years, because I did not know any of this.
Does anyone know if frequent handling of AN bolts and nuts can result in absorbing these toxins? Or do we not worry about it, knowing that stogies and gin are just as good for you? (Sorry, Beauford – had to throw that in! he he he)

Dennis,
Were you been?! Cadmium has always had a fairly well-known reputation for being toxic to human types.
Evidently you never heard of the story of the homeless guy who was using a refrigerator grill as a campfire
cooking grill. According to the story, every time he cooked his meals (rats, cats, or slow dogs), he got a
decent sized dose of cadmium poisoning.
Cadmium, being one of the heavy elements, is a little like lead poisoning. It can cause irreversible liver and
kidney damage, if you expose your innards to it long enough......like cooking a herd of cats, and grilling them
on your favorite Whirlpool fridge grill.
Funny you mention metal poisoning. I still have a little vial of mercury my cousin stole from high school
chemistry class. I used to play with the stuff in my hands. It doesn't seem to have any long term ill-effects,
lucky for me. long term ill-effects, lucky for me, long term...uh, nevermind.
But to answer your question about handling cadmium plated bolts and screws, etc, in the construction of
our airplanes, no, there is no danger. The danger is from breathing fumes, and eating grilled rat, evidently.
Clyde, and Jack Lockamy,
I haven't had a chance to get out to my shop. I'm working intensely on a patent application, which I'm doing
my darnedest to get finished by Monday. In order to do you justice on that boom stand, I was going to draw it
and give all the dimensions, etc. Please give me a day or so to get at it, unless you just absolutely, positively
gotta have it right now! And if that's the case, I'll give up my dreams of being a gazillionaire, and fetch them
numbers. (I promise to have them by tomorrow afternoon at the latest. By then, I'll need a different view other
than this dopey computer, anyway.

Brother Kirby…
Re: Toxins…
Not to worry, sir… The formidable Mrs. Beauford has been out of town for a couple of weeks, but I compensate
by substituting an AN-3 bolt and a couple of 960 washers for the usual olives in the Beefeaters… Have not
yet cracked the code on getting the AN stuff to stay lit long enough to smoke it…likely not as tasty as a Macanudo anyway…
If you are interested, I have a four-page, single- spaced list of things, activities and my in-laws which are guaranteed to
kill the average Kolber before the cadmium on AN hardware…
Worth what ye paid fer it…

I learned that Cadmium is highly toxic..
We play with these toxic things in small non lethal doses more often than we know.
Fluorescent light tubes were filled with beryllium. I don`to know if that is still the case.. I suppose if you spent your time breaking light tubes open and sniffing the contents it might harm you.
Same with cadmium. Don`to make it a part of your regular diet and you will probably be OK
