    I’ve gotten 2 skin burns from chemicals with a nitrile glove breakthrough time of <1 second

    underfunded undergrad lab classes without heavy duty gloves shouldn’t be allowed to use fuming nitric acid >:(

      I’m all fairness, nobody should be using fuming nitric acid unless absolutely necessary.

      At least you didn’t catch on fire. It likes to do that too.

      I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors. After some two hours this condition faded away.

      This was, altogether, a remarkable experience - both in its sudden onset and its extraordinary course. It seemed to have resulted from some external toxic influence; I surmised a connection with the substance I had been working with at the time, lysergic acid diethylamide tartrate. But this led to another question: how had I managed to absorb this material? Because of the known toxicity of ergot substances, I always maintained meticulously neat work habits. Possibly a bit of the LSD solution had contacted my fingertips during crystallization, and a trace of the substance was absorbed through the skin. If LSD-25 had indeed been the cause of this bizarre experience, then it must be a substance of extraordinary potency. There seemed to be only one way of getting to the bottom of this. I decided on a self-experiment.

      Exercising extreme caution, I began the planned series of experiments with the smallest quantity that could be expected to produce some effect, considering the activity of the ergot alkaloids known at the time: namely, 0.25 mg (mg = milligram = one thousandth of a gram) of lysergic acid diethylamide tartrate.

      From LSD: My Problem Child by Albert Hofmann. I will leave it to others to explain all the ways in which this is absolutely hair-raising.

          That was when he took LSD for the first time intentionally. There was one time before that when he absorbed it accidentally.

          It was 1943 and even in Switzerland fuel was not to be had. Incidentally, it was the same day that the Jewish uprising in the Warsaw Ghetto began.

    Chemists from 1925 in 1960… I don’t remember always having this much cancer… Or reduced lung function.

    My uncle was a med lab tech in the hospital. They still had “no mouth pipetting” signs up in the late 90s.

    Do they still sell the Pipetting silly straws somewhere? I was in a Bio lab last week and they didn’t have any (but still told everyone to NOT pipette the E.Coli with their mouths) so I really want to try that now
