      The most dangerous chemical I've ever handled was bromine. There's no fume hood or whatever the name is, so I only depend on where the winds blow. During one of experiment of proving of covalent bonds of fatty acid, I did this experiment near the window, but the wind were not in favor. Instead, the wind blew to inside and some fumes enter my lungs. Felt a bit of hurt in lung and uneasy for two weeks

    During my Ph.D. research I prepared about 10 mL of dimethylmercury for use as an NMR standard. While transferring the product into a bottle I spilled some on the front edge of the fume hood withe a small amount flowing outside it.

      Yes, hexafluorosilicic acid is commonly used in water fluoridation. It will react with concrete if you concentrate it enough, or if you wait long enough.
      For reference, hexafluorosilicic acid is approximately half as toxic as caffeine - LD50 of 430 mg/kg vs 150-200 mg/kg.

      It is physically impossible to OD on marijuana. What you are arguing for is an anecdotal fallacy. The science says it's impossible. Cannabinoid Receptors aren't linked to your lungs.
      People have had acute cannabinoid psychosis and stuff of that nature, and some people have a predisposition to rejecting marijuana, but it is impossible to OD in the medical sense. In the colloquial sense of "oh I had too much and I didn't feel great," yes you can "OD" but that isn't a true, medical, OD.

    As a person who is in their 6th year of high school (12th grade for Americans, year 13 for English people, being Scottish myself) for my Advanced Higher Chemistry we had to do an investigation, of our own choosing , I ended up doing stuff with reductions of sugars using Benedict's reagent, which is all fair and well. The problem was when I tried to titrate it with simple cola, which because of the acid in it formed a little more Hydrogen Cyanide than I would have hoped for, which was a, I'll say, nice surprise.

    The most elaborate precautions I had to take were when handling tritiated water. Tritium is kinda insidious : it's a low-energy beta-emitter, but the beta particles it gives off have such low energy that they cannot penetrate the mica end-window of a Geiger-Müller tube. So detecting it is hard. But tritiated water is doubly insidious, because, in the same way that water exchanges hydrogens between water molecules all the time, so too will tritium atoms swap with hydrogen in water. And, in the UK, there's always plenty of water in the air. And the largest body of water in almost any lab is the body of the researcher....
    Fortunately, tritium in the form of tritiated water passes from the body quite rapidly, with nearly all of it being excreted within 48 hours.

      No, a hammer is completely inappropriate. You use a file and slightly etch the neck, then the top will pop off with finger pressure. No idea what this guy is thinking of. Vials have been used in medicine as well for a couple centuries, and I assure you doctors do not use hammers to open them.

    • @itchykami
      @itchykami Před 7 lety +18

      I think maybe the file would have been far too slow for something that is reacting so violently with the air, thus the hammer. Maybe they could have found a way to file it loose in a vacuum instead? But maybe they didn't have a way to do that.

    • @KB4QAA
      @KB4QAA Před 7 lety +11

    When I worked at an electro plating plant, I used to handle hydrofluoric acid on a regular basis. We had to empty and refill a small-ish acid bath on an aluminium plating line. This involved stopping all the other staff from working, they would go out of the electro plating shop area and wait in the canteen vending area. Then two of us would put on positive air pressure facemasks, full length rubber aprons and elbow length rubber gloves, over our wellington boots and acid resistant overalls, legs NOT tucked inside the boots. Then we would pump out the acid bath into special containers, flush the bath out with many gallons of water. Dry the bath completely, add various acids, including Hf, to the clean bath. The HF "smokes" when it contacts air and other chemicals!!
