Hi there,
I'm basically trying to figure out if there are any harmful chemical in a set of fish test kits and if there is what would they likely to be.
I have 3 boxes one tests for magnesium, one for calcium and the other kh/Alk
The calcium test you add 2ml of water
Then add 1  0.05ml spoon of what they call ca-1 purple colour powder
Then 8drops of ca-2
Then you add ca-3 drop by drop with 1.0ml syringe until it changes from pink red to clear blue

Magnesium
Again same sort of thing
2ml salt water
Add 5drops mg-1 swirl 30secs
Add one 0.05ml of mg-2 powder swirl 10sec
Then add 1.00ml of mg3 liquid until colour changes to grey blue.

Kh/alkalinity
Add 4ml salt water
Shake kh-ind then add 4drops
No powder in this one
Then add drop wise with 1.00ml syringe until changes to blue green to an orange red or pink.

Only the calcium one has a warning saying ca-2 reagent is irritating contains <2% NaOH.
S26: in case of contact with eyes rinse immediately and seek medical advice.
 
I'm researching this due to my nephew may have consumed a bit of one of these solutions out of the test vile. We don't know for sure if he did as it got garbed of him as put it to mouth but wanted to be on the safe side so took him hospital and information on the boxes etc is very limited so they were unable to really know what to test for. The tests they did came back clear and said he can be taken home to monitor. I really just wanted to look into it in case it happened to someone else as apparently they get it a bit with fish products an if someone was to get hold of larger quantity it could be fatal without the information.
So if anyone has any idea at all it would be much appreciated. Then could maybe get some more info online.

Regards
Chris

If you really must know, you can call the poison control hotline yourself.  But if there was a real worry, the emergency room would have done that for you.  The bottles also have simple warnings, and the manufacturer would also help the emergency room and the poison control center.  These are canonical ancient tests, and few people know them.  But the emergency room has already made the evaluation its supposed to, and there's really nothing to do but follow their advice and wait.

Yes they said they contacted the toxic helpline or something as you said. An it was them that said test for a certain thing and that came back clear. They were more going on previous experiences though and couldn't say for certain what was in these actual containers.
All it says on one is irritant and the rest just have a keep out of reach of children picture as most in Dutch. I don't think they could get through to the manufacturer  to find out exactly. I appreciate your advice though an like you say we'll just have to wait and keep an eye on him. It's been 22hours since it happened and seems okay in himself so sure be okay. I just wasn't sure if it was only certain chemicals that could be used and could narrow it down from there to be certain
Thanks again

Most of the chemicals that I can think of that could be present and used in such tests are not highly dangerous. Some chelating agents, some organic color indicators, perhaps something to stabilize pH - while some of them can be irritating, they are not more toxic than a soap or shampoo. Not something that I would like to eat deliberately, but also not something that I would care much about after swallowing some by accident.
