Is it possible to get sick from potassium ferrocyanide?
I just heated some potassium ferrocyanide trihydrate in an attempt to make it anhydrous. I had some skin contact, although I wore a mask. In the past
hour, I have experienced dizziness, lightheadedness, rapid heart rate, etc. Are my symptoms from this chemical, or could they be psychological in
origin (working with cyanide)?

Could perhaps be hydrogen cyanide, but don't worry, if you aren't dead yet you most likely won't be from that poisoning.
Had the same effects you describing from hydrogen azide poisoning, went away in about a couple of hours. Might add that the panic effect probaly
didn't help on the symptoms.
Read up on the toxicity of potassium ferrocyanide trihydrate and its thermal decomposition products and you'll be much calmer (you need alot to die
and you usually die quite fast from cyanide poisoning...).
Any sufficiently advanced technology is indistinguishable from magic.

Why was skin contact allowed? You should have been wearing gloves. Did you bother to read the MSDS?

It
sounded to me like skin contact would be a minor issue. Maybe I was wrong.

From a MSDS "Prolonged or repeated skin contact may cause dermatitis", you're not going to die from skin irritation. Just make sure you wear gloves
and long sleeve lab coat in the future.
by the way I've freaked myself out before thinking that I would die because I (accidentally) inhaled a little bit of Cl2 and got dizzy.

It is posible to get HCN then potassium ferrocyanide is heated?

I agree. See MSDS:

Yes. All the information asked for in this thread so far can be found in MSDS reports. Read them before using a chemical you are unfamiliar with.

Agreed, although it is good lab practice to wear safety gear when handling any chemical . . .principle more than anything.

I would bet that RisingSun is a careful worker and has read the MSDS. It seems that he is not feeling normal (for what ever reason) and is looking
for some help from the forum.

Fair enough, although as I said if he were a careful worker then he would know to wear gloves and goggles, no matter what materials are actually being
handled - be it a 0.1M MgSO4 solution or saturated potassium dichromate solution.

Bullcrap. Who wears gloves and GOGGLES when handling a 0.1 M MgSO4 solution?
Working in a lab and allowing oneself to fall in the state of becoming a drone without a brain is something a chemist should never allow to happen.

While I agree that there is no need to become mindless in the lab, donning goggles and nitrile gloves is as much of a habit for me when entering the
lab as putting on my seat belt when entering a car. I do it without thinking about it, and I see nothing wrong with always keeping safety in mind when
in the lab, even if the days work is rather innocuous. For me the habit was pounded into my head by OSHA compliance at work, and the habit carries
over to my home lab. I see no harm at all in wearing gloves, goggles, and a lab apron when entering my lab. I would say it is a habit that has
probably saved me from injury during some of the unforeseen goof ups that happen from time to time.

i agree , its not so much the chemicals involved in a reaction but the simple fact that i am in a lab and even if i am disolving NaCl in water i am
still surrounded by other much nastier things and since i am rather clumsy i dont take any chances...

everytime I make certain "teas" i get light headed and dizzy from the fumes (water vapor). It is very easy for the mind to create a problem.

some people are more sensitve than other and the psychology of it when it comes to chemicals is way out of my confort zone ...all i know is if i ever
try to make mercury dimethyl (unlikely!!) i would be very nervous and pay close attention to my health, and even the most insignificant change would
really freak me out!

Thankyou Bot0nist. As neptunium says, the other day I personally was dissolving some NaCl into water at varying molal concentrations to determine the
Mr via BP elevation. I had a beaker full of saturated CuCl2 solution at the back of the bench. Hotplate hit it, it fell over and spread a corrosive
liquid all around the metal frames that surround the bench. Shit.
That is why you should always wear gloves and goggles in the lab, it is preparing in case the worst does happen.
Endimion17 - what if I was heating my MgSO4 solution and some splashed out due to superheating? Hot water in my eye, vs hot water hitting some
goggles. Hmm, tough choice.

In practice, I just say don't work with anything which can explode, bump, splatter, poison (short term, sub mL amounts) until you have it in your mind
to ALWAYS wear goggles/gloves. If you're only going to wear it SOMETIMES, you're going to forget or skimp and put yourself in harms way.

As I said, it is a habit that was pounded into me by years of OSHA compliance classes. I don't wear PPE while cooking, but I never even enter my lab
without a lab coat, gloves, and goggles. It is not that I'm scared. It is a habit of mine before entering the lab. I do it almost without thought. IMO
it is a good habit to get into. Better than habitually forgetting to wear eye protection when you need it.

I usually don't wear goggles, because the sash is always between what I'm working with and my face. And goggles tend to fog up or impair my vision in
other ways, causing accidents. But I always wear a lab coat and heavy gloves (usually rubber, they're more comfortable). I consider my laboratory
and everything in it fatally toxic, whether it is or not--and that does me no harm. Better safe than sorry.

You probably should still wear goggles. I thought of using some of that stuff they spray into your helmet when you go paintballing to avoid steaming
up for the same purpose but in the lab.
