Are Airlocks Actually Deadly?

[@bangbinbash]

I'd like to see what effect the escaping air would have on the opening blast door itself. After all it would have all that air in front of it, and a massive surface area compared to a person. That's why I'd think a space airlock would function more like a underwater airlock. The doors would only open after the chamber slowly matched pressure equilibrium, rather then just popping open.

[@dembones5005]

Funnily enough most of the 'depressurizing' dramatic scenes in Trek aren't airlocks - they're shuttle or cargo bays (or random hatches at the end of hallways that *should* be airlocks, but instead let the *entire ships* atmosphere vent through a 3 meter by 3 meter hatch - which would generate forces that might implode a ship) . If they're holding onto something at around the 50% mark of the bay, which is often the case because that's the most decorated part of the set, that's probably a hurricane force wind whipping past them - perhaps much stronger.

[@MasterCleife]

The expanse has a really good representation. In zero g, a room full of people is exposed to space. The people in the room quickly asphyxiate and drift very slowly towards the open hatch. They suddenly accelerate and it's not until you see an external shot that you see why. The spacecraft engages lateral thrusters briefly to move itself away from the dead people. It then engages its main thruster and moves away. Very good.

You forgot to mention "holding on to something" in your tips at the end, because in microgravity even the slightest nudge could leave you slowly drifting out into space! The advice you did give definitely makes sense though, if anyone wants to write a more accurate story involving this trope. But keep in mind that opening an airlock to vacuum typically _does not_ involve all its air rushing out into space in this manner, because an airlock normally gets pumped down to vacuum (recovering that air for later) before the doors _can_ open. Trying to force those doors to slide apart while they're experiencing that much pressure differential could be very difficult, if not _impossible,_ depending on the airlock design (in fact, this may be an intentional safety feature of the design). Also, even if the design doesn't make it mechanically impossible, airlock controls would most likely be designed to simply _forbid_ opening the outer doors while pressurized, with no easy way to override that. The only thing _more_ restricted would be opening both sets of doors at the same time -- _except_ under the very specific circumstances of _a fire onboard_ the vessel or station which has failed to be extinguished by safer means, and which threatens the survival of the spacecraft! And even then, it would be a lot simpler and safer to use onboard atmospheric regulation equipment to quickly but _gently_ lower the pressure, or if that option is for some reason unavailable, to open only the airlock's inner doors and use the airlock's depressurization mechanism in the same way, to avoid the risk of causing further damage from an explosive decompression.

[@wild_lee_coyote]

I love how in the expanse, you can plug a hole in the ship with a binder cover. Remember 1 atmosphere is only 14psi. Not a huge pressure vessel. So the aperture your air is escaping also matters. A slow door will just kill you by the vacuum by the time it’s open enough to get your body out. Another issue is going to be if there is “gravity” in the airlock. If it’s in 0g then it won’t take much to push you out the door. But if you have 1g of artificial gravity then the math gets really funky. I wonder if Kyle included gravity in his equations.

Which leads me to ask this question: who would have a better chance of surviving a suit failure- an astronaut or a deep sea diver?

[@Max_Chooch]

Definitely the astronaut. If you were in a deep sea divin suit like the old timey diving bell suits and your air supply from above suffered a failure, the water pressure around you would no longer be repelled by the air pressure supplied to your suit from above and the water pressure would squeeze your guts into your helmet through your mouth.

[@CarFreeSegnitz]

Pressure differential. In space the greatest differential you’re potentially going to face is 1 atmosphere, the difference between the inside of your suit or spacecraft and the outside vacuum. The deep-sea diver will face multiple atmospheres of pressure differential depending on depth. Every 7 feet of depth adds 1 atmosphere of pressure. The deepest point, Challenger Deep, at 36,200 feet, is a little over 5,000 atmospheres. If a submariner’s vessel failed at 5,000 atmospheres it would be like every part of the person’s body got run over by a truck all at once. Very, very not survivable.

Something that has always bothered me about this trope is the direction the person appears to be shunted out is always straight backwards relative to the camera. In a situation in which you can in fact toss something out an airlock into the cold, dark, unforgiving vacuum of space, you would almost certainly be creating artificial gravity, either by accelerating in a constant direction, or by being on a spinning disk to generate 'apparent gravity'. If your apparent gravity is coming from constant acceleration and the person is standing such that they are in parallel with the bay door opening then as you accelerate away they would appear to you to be flying out sideways as the left the airlock. If you were on a spinning disk then the airlock would probably be in the floor from the reference frame of a person inside the disk so you don't have to fight against your artificial gravity to toss things out, and so that you don't hit a part of your craft with the debris you've just created, but the person would still appear as if they were leaving the airlock sideways. In either case, to get a person to look like they are flying straight out the bay doors backwards relative to the person tossing them out the airlock. They should have their feet in parallel with the bay door opening. That is to say they should be standing on top of the bay doors not having them behind their back as is often depicted.

Hey Kyle, have you ever watched Event horizon? well, the scene where the kid locks himself in the airlock and gets launched out, Laurence Fishborne's character mentioned everything you said about putting yourself into a ball, exhaling the air in your lungs and to cover your ears and eyes. always thought that scene was... chilling to say the least. Love your work Kyle.

[@snjstr]

Would wedging one's self into a corner, adjacent to the airlock, also be a good place to stand? Also, not sure about the Netflix issue. Mine just goes from one episode to the next. Amazon Prime on the other hand, not so much.

[@tedarcher9120]

You would still tie tho

[@LairdErnst]

Star Wars battlefront 2 actually shows an accurate depiction of this science at work. Iden actually steps back from the door to the airlock and stands in front of the door leading to space before it opens. Fun!

[@artemisentriri2096]

I could whole sale accept you being a part of the vsauce group

[@mrmarvel9309]

Opening an airlock that still has air in it is bad resource management.

[@TheInfinityMaster1]

It's not just "flinging out", I remember seeing a movie long time ago (maybe "Alien-related") where a small hole in the wall pulled the alien monster so fast that when he got stock on the wall, all of his inner organs started getting sucked out of his back until his body fully shrink and then was completely pulled inside the small hole out into space. lol

So, if it's moving at Mach 1, you're telling me I can't make my Alien hybrid clone child get sucked out of a quarter sized hole in my ship as it screams in agony and gets turned into guts spaghetti?

[@tarkett8529]

[@JellyPieCharms]

I was just thinking about that only watched that movie a week ago and thought how unrealistic it seemed

[@packered]

The various times people have been spaced in The Expanse have generally handled this pretty well. Either the airlock has been opening in the direction of the acceleration being used for artificial gravity or it's done under no thrust and the person just gently floats out.

[@stephiregaming7927]

"The great empty" has to be the best nickname for space i have ever heard

[@blairbuskirk5460]

Depends upon whether it is pressure equalized before opening or if it is a violent decompression event. While the latter can send untethered objects into the void the former is like opening a door at sea level.

[@xplosiv211]

So you're saying event horizon did this the most accurately in cinema? That movie is amazing

Thank you.

Oh jeez is that the one where one of the guys got sucked thru a little tube and got his insides spewed all over?

[@dogmaticpyrrhonist543]

Interestingly, this is similar to how hyper-sonic wind tunnels work. The other variables are how big that airlock is (eg, if the whole craft depressurizes through a fresh hole right next to you, it would be BAD) and how fast the "doors" open. In a hypervelocity wind tunnel at the Uni I went to, they had a "door" made of a steel sheet with lines scored in it, and "opened" it by pulsing a laser in the middle to drill a hole enough that the whole sheet would collapse away from the middle.

[@dcdanger7597]

I'd think so considering airlock accidents have killed people on earth

[@dh510]

I havs some more questions regarding that topic: 1. Wouldn't that sudden pressure change rupture your eardrums? 2. Can you get decompression sickness from this pressure drop? 3. How much would a human body cool when the pressure drops from 1 atm to 0? Would that be an unpleasant chill or could that freeze you to death?

[@thcottie]

Hey Kyle, can you breakdown a couple examples like from Guardians of the Galaxy 2 vs The Expanse?

[@TheVeritas1]

Great idea.

[@salixalba6536]

or the airlock scene at the end of Aliens where they were near the middle of a large hanger room and the airlock was opened right next to them. He did show a picture of a xenomorph so we know he's aware of it

[@Majere613]

In addition to whether the force of air would be able to suck (or possibly more accurately, blow) you out of the airlock, you'd also need to consider whether the airlock would even open that way at all. An airlock usually equalises its interior pressure with that of the exterior before it opens precisely to avoid flinging things out of the spaceship/ submarine/ underwater lair. In order to explosively 'space' someone you'd need to at least defeat some of the safeties designed specifically to stop it happening.

[@duhontheguy]

Oh boy, this sure is a great video that was just released! I sure do hope in the next 5 seconds there aren't hundreds of comments saying "Early"!

Can we get an answer to why he smells like bacon after getting reconstructed?

He is made of pig meat most likely. Ps. Humans and pigs have very similar DNA, something like 95%.

The grill marks.

[@SteveStanger]

Because bacon!

Is it just me or does the "Don't worry about it", followed by instructions on how to survive make you think this is how Kyle preps his minions for Pop Quizzes.

[@tparadox88]

"Correction, sir. That's 'blown' out." - one of the rare times they accidentally let Data use a contraction.

[@dunzerkug]

The high delta P method for ejecting material reminds me of how some supersonic wind tunnels are run. If you don't need to maintain a supersonic flow for more than say 10 or 20 seconds to get the data you need having a giant bank of compressed air that is channeled so as to create a laminar flow works great, just be sure all your data recording is working BEFORE activating the wind tunnel, they can take tens of minutes to a few hours to recharge the air bank for the next shot.

[@Strype13]

I would have to assume larger people appreciate you using the "less aerodynamic" label over many of its counterparts. What a gentleman.

[@B00s3]

Kyle mentioning Dan Casey, put a huge smile on my face. I don't miss BS, like I miss the interactions between Dan and Kyle. Truly miss seeing you 2 together.

[@MinistryOfMagic_DoM]

No matter what Discount Thor will tell you, the answer is: if the pressure differential is high enough and the hole big enough: yes you can be blown out.

[@theatheistpaladin]

7:36 looks like we need another Kyle.

[@cosmicphoto05]

I know this is ridiculously obvious for this channel, but I'm glad you exhaled before the airlock was evacuated. Also glad that The Expanse gets this right for the most part.

It also depends on how the door opens. If it opens slowly from the bottom, like a garage door, you're probably safe even up against the door. If it opens from the center like an elevator (fast or slow) and you're the only thing in the way of all that air, then you belong to the stars now.

I'm reminded of the Vogon airlock in Hitchhiker's Guide to the Galaxy. It opens on the floor so you have to stand on it and get flung out.

[@erinkarp6317]

If it didn't automatically repressurize at least whoever is in the airlock would die anyways from the vacuum of space.

[@Hubris2]

Agreed - we aren't discussing how long you can survive in a vacuum - just whether your body is lifted from the ground while you try to hold onto something (while not being sandblasted by small particulate matter moving past you) as a huge wind tries to pull you into space. If it's just the airlock and not an entire ship being vented, standing further away from the opening makes a massive distance on the force.
