tak posted:Phlebotomy lab techs used to mouth pipette blood not that long ago (80s) Oh good, that really happened. I was in the hospital a lot as a kid in the 70s and I clearly remember the vampire nurses, but wasn't completely sure it wasn't just something I dreamed.

Most of the time they straight up admit it's the convenience of not needing to attach the bulb or find the tip refills for the autopipette but they'll occasionally trip over themselves to say bulbs are harder to use accurately and the autopipette keeps getting out of calibration.

I believe that the lip and tongue are more sensitive than the rubber, but it's still not worth the risk.

I remember watching a video in science class about a guy mouth pipetting some water and he knew it was acidic because he felt his teeth fizzing.

Re: whaling, remember this good old unit of measurement.quote:The term candlepower was originally defined in the UK, by the Metropolitan Gas Act 1860, as the light produced by a pure spermaceti candle that weighs 1⁄6 pound (76 grams) and burns at a rate of 120 grains per hour (7.8 grams per hour). Spermaceti is a material from the heads of sperm whales, and was once used to make high-quality candles.

Reminds me of my high school phys/chem teacher who, I'll note, had a license to make his own fireworks and gunpowder. One day someone asked him why one of his thumbs was all weird and withered with a perpetually damaged nail. Apparently at one point he had two containers, one of water, one of high-concentration sulphuric acid, and forgot to label them. Not wanting to bother to get the colour-changing paper to test them, he just jammed a thumb in each tub and waited to see which one started hurting first. It may have been a bullshit story, but knowing the guy I could believe it 100%.

I vaguely remember watching a video like that, for some reason the scenario took place near a pond and the only thing he had to wash his mouth out was a big heapin' helpin' of pond water, served up in some random styrofoam container. I've also very nearly put acid in my eye while using an ancient autopipette machine to fill a couple hundred tubes for a college lab course, because the hose kinked and the tip flew out of my hand and I was a dumbass that didn't think to put safety glasses on. Thankfully I didn't become an OSHA story, but watching the stream of acid arching in front of me was certainly a thing.

https://meduza.io/en/feature/2019/08/22/there-s-no-danger-get-to-work So much osha in that nuclear incident.quote:When conducting any work like this [with the missile], the soldiers should have deployed decontamination checkpoints at the testing site — there should have been at least three. The first decontamination point should be at the border between the clean and contaminated zones. Even in the absence of a major accident, individuals leaving the danger zone must pass through this checkpoint with any equipment they touched, and they have to be processed and decontaminated of any radiation. At the next checkpoint, these people have to remove all their clothing (which needs to be destroyed), before they’re cleaned and decontaminated again. After this, they’re checked again for radiation levels. People who come up “clean” are released, but anyone with abnormal readings has to be taken to a military hospital. Before they’re loaded into an ambulance, they need to be washed again and then yet again, when they arrive at the hospital. Before any surgeries, patients should be decontaminated once again at the hospital. Only after all this should doctors treat the patients. quote:And the most absurd thing in all this (though I struggle to single out what I think is “the most”) is that they didn’t leave our vehicle (a mobile radiation-chemistry laboratory) at Vaskovo Airport, where they brought the victims. Instead, they sent it to Severodvinsk to measure its radiation levels. At that time, there were reports that sensors there were showing heightened radiation levels. So our car went there, and an additional team drove to the airport with a gamma-ray sensor and nothing else. This was on orders from senior officials (not the managers at our rescue service). quote:On August 8, at 4:35 p.m., three people injured at a military testing site were brought to our hospital. We doctors directly asked if any of the patients had been exposed to radiation. The patients’ escorts told us that they’d all been decontaminated. They said, “They’re no danger to you. Get to work.” quote:Some time later, when we were already in surgery with the patients, the dosimetrists showed up and started measuring beta-radiation levels. They ran out of the operating room in terror. Doctors caught them in the hallway, and they confessed that the beta radiation was off the scale. quote:And another important thing: we risked the lives of the other patients who were in the emergency room at that time. We closed the area only after we realized that we’d admitted three patients who’d been exposed to radiation. The whole time up until this, literally steps from our victims, there were teenagers, pregnant women, and people who needed medical attention, all just walking by. quote:The medics from the military came to our hospital only later. When we started telling them about the victims’ exposure, their diagnoses, and invited them into the patients’ rooms, the medics said, “No. We have children,” and “I’ve got so many kids and I’m not going in there.” Well that’s just great. Meanwhile, without any warning, the doctors at our hospital spent a bunch of time with these patients, the anesthesiologists each spent six hours with them, and these military medics don’t want to go inside for a single minute. quote:At Burnazyan, they found cesium in one of my colleagues. He’s a young man, and his wife is currently pregnant. At the medical center, they asked him where he’s gone on vacation in the past few years. He started listing all the places, and said he’d been to Thailand at some point. When they heard this, they said where there’s Thailand, there’s Japan: “You must have eaten some Fukushima crabs!” The man had been in contact with cesium for several hours, he’d participated in surgeries [with irradiated patients], and he’d stood over the patients without a respirator mask. Then he goes in for an examination, and they tell him: “Oops, well, it’s your own fault. You brought it home from Thailand.”

Imagined posted:When you look up any crazy element or chemical discovered more than about 50 years ago you'll always see notes about what it tastes like. Apparently combining random poo poo and seeing how it tasted was just how chemists rolled back in the day. back before real analytical chemistry, and well before technologies like spectrometers, the directly observable characteristics of a compound were the only way to identify it. i read a really old chemistry book once (1850s) that categorized chemicals by everything you could possibly detect with your senses -- basic stuff like color, solubility and crystal shape of course, but also the smell, the taste, the feel when rolled in your fingers, even the sound the crystals made when crushed.

Fun fact: Palm trees can also serve as human flesh zesters if the proper amount of kinetic force and aforementioned flesh are added to the tree trunk.

Yeah, but how cool would it be if that van were electric and everything in it, including the door handles themselves, were controlled by electricity. So when the battery inevitably catches fire, it locks you in the burning car?
