Contact dermatitis? On darkroom safety

Can you tell us their brand name and model, if applicable? Grainger.com or Mcmaster.com might carry them.

I have no idea what brand - I bought a package of 10 pairs of them when I bought some kind of nasty lacquer thinner about 10 years ago. They are chemical resistant, hard to pucture. You can take one off and put it on again without having any fingers turn inside-out. They're not disposable - and the thing to remember about something called "disposable" is the manufacturer expects you (even if you're a proctologist, @DREW WILEY ) to throw them away after you remove them. I put on and take off the gloves I have a dozen times or more when in the darkroom.

I was using disposable gloves. Can't count how many times they ended up wet inside. Gloves that don't go past my wrist, I find useless.

Edit - I looked up gloves on Amazon. There are Lanon branded ones that look similar to what I have.

This might have been easier as a poll. I hope someone is keeping count!

In the 1970s, all the real printers I could find dabbled their fingers in the trays, so that's what I did for the first few years. Then in the 1980s I adopted tongs, mainly to keep my darkroom uncontaminated. Nowadays I am health-conscious too. If I feel compelled to dabble, or am handling raw chemicals, I use yellow washing-up gloves. And a mask (and of course my acid-proof safety sandals!). I don't have contact dermatitis, but then I've never done huge volumes anyway.

@Bill Burk: any idea what Ichthyol is/was? Fish oil? Might not do wonders for one's aura.

To my knowledge some will always remain, therefore multiple rinses might be required (therefore the multiple water changes when rising the Ilford way).

I think that's to do with diffusion out of the emulsion. For a smooth surface, rinsing should be pretty efficient, especially with warm water.

Amidol turns your nails black:

I don't remember seeing that ever, but in those days many people used cigarettes to get a deep yellow.

I use these:

SAS Safety 66519 Raven Powder-Free Nitrile Disposable Glove, X-Large, 7 mil Thick (Pack of 100) https://a.co/d/aSwWMLL

They are disposable and I never try and reuse them. They're not the cheapest, but they seem to be good quality (I've never managed to tear one).

I also have a pair of the Lanon gloves which I use when printing, but they don't allow for enough dexterity when developing film - I could see myself dropping the developing tank during inversions if I wore them.

Now rock star wannabees have their nails deliberately blackened. But amidol is a pharmaceutical ingredient too, and has its own potential health risks.

Totally missed that one.

Looks like water is the greatest hazard in your darkroom.

We all know how great a hazard dihydrogen monoxide really is

Dihydrogen Oxide No need for the mono mano.

Like I said, it's pretty nasty stuff.
Though I feel that Hydrogen Hydroxide is probably worst

You don't want to get dehydrated or your eyes will itch. That's why I've told beginning backpackers to go to REI and purchase packets of freeze-dried water. And some have done just that,
and asked for them.

Desiccated or dehydrated water is much lighter to carry in a backpack, especially when the total backpack weight is of concern.

Might have something to do with the contamination that apparently arose in the database:

Whatever reason, it's still funny.
