I know we have some scientists and doctors here, so my question is the following:

Given what perplexity produced below regarding the toxicity of these Hanna reagents - specifically that it can be absorbed through the skin (last bullet point) - should they never be handled without wearing gloves?

Whenever I read "scientist" I am reminded of a funny movie scene in half baked. :D Sorry got sidetracked.

The instructions you posted also suggest protective eyewear in the 4th bullet point. How often are you testing phosphate with the hanna checker these days?

<not a scientist, or Doctor>

That is most likely the verbiage from the source SDS. I suspect the small amount you'd get on yourself, or inhale, would be too little to do anything to you.

Most I've gotten on myself, testing commercially, is a drop or two. Never inhaled anything.

I've spilt more vials then I care to count though :(

Me either on the doc or sci front.

Good to know about the small amounts!

I am really good at not testing phosphate... Like pro level good. I should see where its at these days I suppose.
 
I was director of aquaculture for a large aquaponics outfit for a spell. We tested a lot.

At home, I'm in your wagon :) I have a few new meters that haven't been taken out of the box.
 
@Alexander1312 -i do look at those warnings and wonder. I just keep my nose and eyes away from it (and no fan) and call it a day.

I test PO4x generally 2x a week. Of course you can a get a trident NP or hydros maven whenever it actually comes out & not worry at all!

The Hanna nitrate and salifert CA also have warnings but the skull on the phoshpate reagent made me nervous (after several years using it…).
