    As the flipside to the question, pretty much any customer facing job like retail, sales, or food service have been spot on, especially if they are specifically calling those industries out. Superstore, Waiting, Office Space etc. are so damn accurate to the pain of working them.

    To the original question, I think it was mentioned earlier, but anything with a gun is typically wrong. The struggling artist who can afford immense loft apartments in downtown cities. Ghost hunting/supernatural expeditions are so glamorized. They NEVER tell you how much time it takes to review everything.

    You don’t need a huge wrench when working with the p-trap under the sink and water wont start spraying everywhere either as drains aren’t pressurized.

    Sprinklers react to heat, not smoke.

    Not all spriklers go off at the same time in most systems. Only the sprikler heads affected by heat.

    The water coming out of sprinklers initially isn’t clear but dark, rusty sludge. Sometimes even black as ink.

    Not really a hobby but I do hunt, so I find myself rolling my eyes when I hear 18 or more shots out of a pistol, 9 or more shots out of a shotgun and 31 ot more shots out of a semi-auto rifle with a pistol grips. The other eye roll is the unnecessary cocking and re-cocking of the shotgun without ever firing a round. If everything in the show Archer is true, then I may be on the spectrum lol. Except there’s no fucking way I could dual focus counting rounds while shooting any gun even itmf its at the range and noone is shooting at me. Movie/tv tho im counting every one.

    The number of people who are “knitting” in a movie or on TV…maybe 40% of them are actually doing it, and that’s a high estimate (shout out to Miss Marple!). The rest appear to be wrapping yarn around one of the needles and then moving it vigorously, lol.

    One thing that bothers me, and what everyone should know, is proper placement for defibrillator pads if you’re using an AED.

    It’s not 2 pads on the chest, it’s one pad on the upper chest (almost shoulder) on one side, and the other pad goes lower on their side. You’re trying to have the current go through their heart (not skip over the top of their skin).

    The AEDs found in public locations are all very easy to use and all have pictures for the proper placement. Just open it up and it will tell you everything you need to do. Have someone nearby look for one at the same time you’re asking someone else to call emergency services.

    They should all have razors if you need to get a little hair off (in case the person is especially hairy for one of the pad placements).

      It’s also very advisable to do a basic AED course. Its just a single afternoon, but it’s immensely valuable to have at least once practised with how to properly use an AED. Often they also show other techniques, like Rautek (dragging someone semi safely) or how to use the kiss of life (a mouth to mouth ventilation mask)

      If they have a second set of pads with it; put the first ones on and rip 'em off quick, taking the hair off like a wax job. Then place the next set of pads

    Oxygen tanks are not bombs. They won’t explode or shoot fire. The reason they’re painted green is because oxygen is non-flammable. (those red acetylene tanks however, are scary)

    Now obviously any existing fire can be made much worse with oxygen, but it’s not enough on it’s own.

    I was led to believe that shipping crates open up easily with one quick pry of a crowbar. In reality, those things are built with so many nails and screws that it takes more work to tear it down than to build it.

    MRIs

    Far too many movies and TV shows use the magnet to cover for their lazy writing by treating it like something that can be turned on and off like a light.

    The magnet in an MRI is one of the coolest things in medicine, and writers get it wrong all the time. In the vast majority of cases, it’s always on.

    In simple terms, an electromagnet works by running a current in a circle and creating a magnetic field. In an MRI, the current is flowing in what is essentially a closed loop of wire. However, in this case the wire is cooled with liquid helium so it becomes a superconductor.

    They induce a current in the wire which creates the magnetic field (“ramp up” the magnet). Because it is superconducting, the current doesn’t stop. Once it’s ramped up, it no longer requires any external power. As long as the current is flowing the magnetic field remains.

    There are only two ways to “turn off” the magnet.

    One way is to “ramp down”. Essentially the opposite process that is used to get it running in the first place. That’s what they do if they need to stop it for service.

    The other way is to quench the magnet. You hit the emergency stop and vent off the liquid helium. Without the helium, the wire warms and resists the current and the flow stops.

    Quenching a magnet is a magnificently dramatic process. Someone hits the panic button, and there is a loud roar as the helium escapes. Clouds of condensation form around the exterior of the building as the cold gas escapes. In the event some construction crew screwed up and accidentally sealed the vents, there could be an explosion from the rapidly expanding gas.

    If writers want to use an MRI as a plot device, have an accident and require someone to quench the magnet to save a life. You’d have the immediate drama from the accident and the quench, and then you’d have the long term drama of the hospital trying to figure out where the money to fix the MRI would come from.

      I used to install and maintain MRIs (as well as some other medical imaging modalities) and this seems to be wrong any time I’ve ever seen it in media.

      1. people will be shown in the magnet room with steel wheelchairs/patient tables/chairs/etc. or even their phones. None of that should be entering the room at all.
      2. the images shown on the diagnostics will be like a radiogram or PET or something that would not show from an MRI.
      3. the scan only takes a minute for a “picture”, when in reality having an MRI scan can easily take an hour. You may have some people taking only 15 minutes or so, but those are the quick ones. Clinicians will order a whole list of scans and each one takes several minutes.

        Years ago where I work a resident decided to be helpful and move a patient into the room with the MRI.

        Of course, the patient was supposed to be transferred off the ferrous metal gurney before coming into the room. The resident didn’t know that.

        The MRI pulled the gurney into the room and it slammed into the scanner. Luckily it didn’t actually flip up and crush the patient.

        They told the patient to stay where he was and they loaded the gurney down with a bunch of full five gallon water bottles. Once they had enough weight on it, they transferred the patient off the gurney. A bunch of guys pulled the gurney out of the room, amazingly without any damage to the scanner.

          Yes I had two separate occasions of having to remove a ferrous table from a magnet. One was able to be removed with 5 of us pulling (using a tie strap for safety to make sure it didn’t fling when we repositioned it), but the other we had to ramp down the magnet to remove from the room.

            How about small things like paperclips and staples? My guess is that it won’t be too hard to pull but not so easy to get a good hold.

              Unfortunately they did get in the room sometimes. For the most part, techs are really good about keeping the magnet room clear and not bringing ferrous items inside. However, even when things like that did get inside they really aren’t a problem to just pick up with your hands (or sometimes our titanium tools like pliers or a screwdriver to get a better grip on them). The pull is strong, but based off the amount of ferrous material so those things that are just a few grams are not really notable.

      It wouldn’t be nearly as fast, but why would you not just stop the condenser pump so the helium stops cycling through, causing the freezing, instead of venting it off? Sure, venting it off would be faster, but in the lack of an actual emergency, you’d think you could wait like 5 minutes.

        If it’s not an emergency, then you let the vendor follow the procedure they have in place for shutting down the magnet.

        Edit:

        For example: We had a flood in an MRI room. The vendor was called out to ramp the magnet down so that they could deal with the flood.

      It’s actually very rare that Hollywood makes non-nature movies that use correct animal sounds(and it’s often not correct in animal focused ones either). For birds they especially tend to use sounds that are exclusive to North America, even if the setting is in on another continent.

      There’s the classic of kids asking why they’ve never heard the “ribbit ribbit” sound in nature: The pacific tree frog only lives on the west coast of North America.

      And let’s not forget almost every single time you see a bear “roaring”, it’s almost always mixed in with lion roars and such. In real life a black bear “roar” sounds more like a cow going “moo”.

          Thank you so much! Recently I have been trying to recall what bird made that sound in so many games and movies over the last decades. For some reason it is often put into jungle or lush biomes in games. And it has really annoyed me that I didn’t remember what it was called.

    Having served in the U.S. military, I cannot unsee the fact that movies and TV shows ALWAYS fuck something up with the character uniforms-- Army rank on Air Force cadets, upside-down rank, badges pinned on the wrong side, the character is a Sergeant Major but they’re wearing Major rank, the character is wearing ribbons for wars they weren’t even alive to have served in, and so on.

      I almost wonder if they intentionally screw that sort of thing up so they’re not “ripping off” real soldiers’ customs.

        I hadn’t considered your first point, maybe that’s it! I also wondered if maybe they just thought whatever they did looked “cooler”, so they went with that? Because yeah, you can totally hire a consultant for that kinda thing, or heck, just look it up online!
