I know I should, if something explodes the glass could break and create a bigger problem than before. I'm just going to buy a full face shield one of
these days.

Ah, the foolishness. A face shield is a SUPPLEMENT for glasses or goggles, NOT a replacement.

Yes, goggles for the eyes( good pairs don't fog up much) and a face Shield over it when working with grinders, pressing caps, shaking sulfuric acid
with elemental bromine in a Sep funnel to dry it  , etc.

That last one was pretty specific, any story to go with it?

I don't use gloves, except for really nasty stuff or for stuff which quickly can pass through the skin (e.g. conc. H2SO4, conc. HNO3, mercury salts,
liquid Br2, solutions in DMSO). I have a tap in the lab and if I get some chemicals on my hands, then I immediately rinse them away with some water.
Without gloves I can feel much better and I certainly can handle things more safely than with (thick) gloves.
I have glasses and these provide some protection. Using goggles is the same for me as using gloves. Only in exceptional cases (e.g. when I work with
small amounts of energetics in test tubes or when I think there is a chance of strong splashing) I use goggles.
Usually I do not do very dangerous experiments and if I play around with energetics then I use exceptionally small quantities (tens of mg, little heap
on the tip of a small screwdriver). I personally think that the use of very small quantities is the best safety measure one can take. Many experiments
work equally well with 50 mg as with 1 gram, but are a lot safer with 50 mg. This is true for the risk of fire, explosion and the risk of poisoning
yourself.

My practice in the lab is very similar to woelen's regarding gloves and safety glasses. I do have the advantage of an efficient hood with a double
pane safety glass sash. I perform all my experiments in my hood, but only turn the fan on when I think it is needed. Same with the sash - I pull it
down when needed.
I emphasize keeping the rest of the lab clean, ie, practice good hygiene by cleaning up glassware and disposing waste promptly. I do a full range of
chemistry with emphasis on organic. Most of my inorganic preps are to support my organic experiments. Also my scale is usually around 10 grams.
In regard to potassium ferrocyanide, I weigh it out for drying using no safety equipment. I use a spoon so I never actually touch it. I have read
the MSDS and see no reason to wear gloves or goggles. Like woelen I wear glasses. Linus Pauling in his General Chemistry textbook says that
ferrocyanide is so stable that it is even difficult to get it to react with acid. I assume he means at room temperature.

These symptoms sound more like a panic attack than poisoning. I think what could have happened was that you THOUGHT for a moment that you heated the
compound to decomposition temperature, at which point you feared cyanide poisoning.
Having been in a similar position before, I can relate to it and I know it's not fun. The brain is really good at playing tricks.
As mentioned before, if the symptoms have passed, sit back and take a deep breath of fresh air, you are not under any immediate danger. The symptoms
of cyanide poisoning are quite different, rapid heart rate not being one of them.
Hope this was helpful.

Several years ago there was a fatality at the facility i was working in involving skin contact with Kferrocyanide. Its not as innocous as one might
think.
After the investigation by the university the death was attributed not to the intial Kferrocyanide skin contact, which had been widely blamed for the
fatality, rather it seems the next twenty seven tonnes of the chemical that sluiced out of the hopper crushed and asphysixated him.
People still dispute the finding, the university has now altered its practices and trains people not to stick poles directly up into open hoppers in
an effort to loosen the caked up chemicals.
Apparently he was wearing gloves and goggles but was texting at the time of the accident.
His concentration may have been diverted because its really hard to text message wearing huge pvc gloves. The university has now banned this practice,

This story is not true, rather it is a witty aside.
