<p>Thanks for your answer. I am usually very careful, today I have been a bit hurried and I did contact the anti-poison center in my city well before writing my message here. I came on this forum to have a confirmation on what the doctor told me on the phone; he wasn't concerned, but I don't believe these kind of centers usually receive many calls about such specific substances, and that's why I'm simply here to hear from others about their practice. For example, if someone answers here saying that they hairdry with hot air their cyanotype papers without ever having problems, I would have been reassured, that's all. <br> I do not have any particular fear about photographic chemicals in general, I practice regular analog photography without any problem, but I am fairly new to cyanotype, which I am studying alone, so, having been for once a little less careful, I came here to read about other people's experiences.</p>

<p>Hello everyone, <br> I'm a young student from Paris, France, and today was my second time doing cyanotype prints at home. I have never taken any classes, just studying independently for my graphic design and photography studies.<br> Today I was in a bit of a hurry, and I wasn't wearing gloves while handling the chemicals. One of the two liquid solutions, not sure which one because they are kept in two identical brown bottles, fell on my hand, which I promptly washed. I have no rash or anything like that, but I'm still concerned about any possible risk, even though I called the local anti-poisoning center where they told me it shouldn't be much of a problem. But much worse, I believe, I completely overlooked the danger of heating the solution of the two chemicals: I hairdryed my emulsion on the papers without the cool setting, in my small and windowless bathroom. And I used a UV lamp to make the exposures, again in a non aerated space. It was really stupid of me, I didn't do more than two cyanotypes, but still, I am wondering if, even though I have no symptom, I should seek medical attention to make sure everything is fine. I may be overly preoccupied now, but I know that heating the mix of potassium ferricyanide and ammonium iron citrate can produce highly toxic gas. </p> <p>I was wondering if any of you can share some experiences that could reassure me.<br> Thanks a lot in advance,</p> <p>Manu</p>
