pressure suits

Brotherhood Suits vs Real Life

I have been told this a couple times that these suits don’t exist and are silly.

Well they’re right to a point. Those specific model of suits don’t actually exist but they’re updated based upon 1950′s and 1960′s pressure or g-suits.

These suits were designed to combat the high g forces that pilots were subjected to. The suit itself maintains pressure on the body to force blood to not pool in the limbs and keep as much of an even bloodflow as possible.

This really makes a lot of sense in the context of Fallout. Power Armor is a suit that you pilot and it is subject to a hell of a lot of g’s from jumping off a building to taking a hit from a Death Claw or a Missile. You’re suddenly hit with a ton of g’s that can really wreck your day. The suits are pretty much a necessity for pilots of Power Armor.

After explaining this to someone they then told me that the orange or pink version never existed.

Really? Half the suits Nasa uses are orange and if you need further proof that odd colors existed here’s a gold one.

This also explains why there are so many pilot helmets to be found in the commonwealth. Fallout 4 overhauled the way Power Armor works and I think it’s honestly for the better because it’s a lot cooler to have you step into a suit of armor then to just throw it on.

     When you picture a test pilot or astronaut wearing a pressure suit and strutting to their sleek ship, the mental image is not complete without them toting along a little metal briefcase connected to their suits via hoses. This yellow box is a portable liquid oxygen converter and serves the all important function of cooling the human inside the suit. Without cooling, the heavy layers of a pressure suit would cause the crew member to overheat within a matter of minutes.

     The simple device has no moving parts or electronics. It contains a small tank full of super cold liquid oxygen, constantly heating up and boiling away into a gas. The cold gas expands through the coil of tubing surrounding the tank, then travels through a hose into the suit where it’s distributed through the crew member’s cooling garment throughout the suit. Some of the oxygen is directed to the crew member’s helmet, allowing them to breathe 100% pure oxygen prior to the flight, purging their blood of nitrogen, thus avoiding decompression sickness, otherwise known as the bends.

     When the pressure suited individual sits in the cockpit, a supporting crew member will disconnect the portable system and connect the ship’s integral oxygen system which serves the same purposes during flight. Equipment identical to this was used during the Blackbird program. This interesting little artifact lies on display at Blackbird Airpark in Palmdale, California.

The NASA Village

Today in the NASA Village… A Hand in Everything.

Our spacesuits are built up from various piece parts, torso, arms with sizing rings, legs with sizing rings, boots, helmet, and gloves. The variation of the different pieces allows the engineers to construct a suit from generic hardware that fits, or at least come as close as they can make it. One of the most important elements of a spacesuit are our gloves. They are the only piece tailored specifically for us. Spacewalking is a bit of a misnomer on the International Space Station, since we don’t do any walking. We are floating and have to use our hands as the means for moving ourselves from place to place. This sped up example of one of my pool runs demonstrates this form of space “walking.”

With the increased pressure of the suit (to protect our bodies from the vacuum of space) and all the operations with our hands, it can be very fatiguing. Hence, the custom gloves allow us to work for longer periods of time, with much more dexterity for repairs.  

How do you make custom gloves?

Bobby Jones literally had a hand in everything, because his work included making my space suit gloves. He noted that “as part of the process, we traveled to Houston to make casts of the astronaut’s hands for use in the design process. The hand casts are very life like.  When I had these hands all over my office it looked like a zombie movie, where the dead are coming back to life and digging their way out of the ground.”

This scary looking hand looks familiar! Using the hand molds, the engineers make the design requirements for each aspect of the glove. They determine the EXACT dimensions that are required in order to have the knuckles bend in just the right places, with just enough spacing to allow the hands to flex more easily, but snug enough to provide the needed dexterity.

Then with those very precise patterns, the fingers and palm are hand-sewn within tenths of millimeters of margin!

Olga Bustos is shown sewing the fingers of a glove. She has been sewing gloves since the Apollo days and even participated in the construction of Apollo era space suits.  

The space suit has to be pressure-tight. In other words, while working in the vacuum of space, we don’t want any leaks! The inner lining of the suit is cut according to a very specific pattern and then the pieces are heat sealed together to form the barrier that protects us from the vacuum. You can see the yellow inner bladder being heat sealed by Whitney Lowery. You might be surprised that her degree is in fashion design!

There are other layers of protective material over the inner bladder, which is why you see the white fabric on the outer surface.

Fun facts you may not have known about spacesuits: The space suit weights 250 lbs with the backpack. 

The suit components come in sizes like medium, large and extra-large. (Females have to work that much harder in a spacesuit because of all the extra room).

The suits are all hand sewn on old sewing machines.

The gloves take 14 months to design and build.

Engineering is a good start, but they don’t teach space suit design in college. Get exposed to as many things as possible if you want to work on spacesuits someday.

     No cockpit demands as much intense focus as an SR-71 Blackbird’s, and in frustrating irony, no cockpit offers a better view. There was no time to look out the window. The plane knew when your eyes started to wander to the spectacle of earth from 85,000 feet; that’s when something would go wrong. There was much to monitor. The many “steam gauge” instruments reflect a bygone era, giving the pilot information ranging from heading to compressor inlet temperature, each dial representing a critically important system.

      Even though this cockpit was operated through 2,854 flight hours, it looks brand new. That’s because it was only ever flown using the gloved hands of a crew member wearing the essential high altitude pressure suit. Every control is large enough to be adjusted with those bulky pressure suit gloves. 

     You sit atop your throne, the SR-1 ejection seat, which carries a rare 100% success rate. To operate the circuit breakers, you must reach beside and behind your seat, outside your field of view through the pressure suit helmet. To make sure you actuate the correct breaker, you count down the rows and columns by feel.

     March Field Air Museum in Riverside, California, is kind enough to display SR-71A 17975 with her cockpit open. This gives us a rare peek inside the world of the Blackbird, allowing us to look inside something that was formerly top secret and reserved only for a privileged few crew members. These photos were captured using a camera extended into the cockpit via monopod. At no point did I or my equipment come in contact with the artifact.

Sad agony klance idea. While on a planet with air that isn't breathable to humans, Lance's helmet breaks from a battle with just him and Keith around. Before he blacks out from the lack of oxygen, Lance feels his helmet get pulled off, then put back on. When he's able to think and see clearly he realizes with terror that Keith gave him his helmet and is currently loosing consciousness. How this ends is up to you. Do they both live or die?

Lance’s head is throbbing horrifically when he blinks his eyes open. He sees strange black spires crisscrossing above him like the threads of a giant spiderweb and feels himself going crosseyed as his vision tries and largely fails to focus. Where…?

Justice League Games

Much to everyone’s surprise, the undisputed master of Watchtower hide-and-seek is not Bruce or J'onn, but Ollie.

Clark had suggested they play in the name of detective and stealth training, but everyone (except Billy) knew that the big ol’ cinnamon roll just wanted to play with his friends. Bruce is, of course, really good at the game, and so is J'onn (once they explained the rules to him). Guy is the worst, followed by Diana–they’re a little too hard-headed for it, and it doesn’t help that Guy keeps giving away his hiding place by glowing (He hasn’t realized that Hal and John take their rings off). But the best? The best is Ollie.

Bruce and J'onn rely too much on stealth and misdirection for a game where they don’t move, but Ollie is a sniper, and it shows. He pops up in the weirdest places–beneath the engine block of one of the Javelins, inside the cabinets of the med bay, inside Zatanna’s closet–she swears the door was magically locked, nobody can figure out how he pulled that off–or hiding in a corner of the ceiling, just in Shayera’s blind spot. He once spent 45 minutes inside an underwater pipe in the conservatory’s pool, just to surprise the hell out of Arthur.

Then, one day while the Batkids were aboard, Ollie made the mistake of challenging them to hide-and-seek. They found Tim three hours later, sitting OUTSIDE THE WATCHTOWER in a pressure suit that he’d somehow smuggled on board four days earlier.

“Three steps ahead,” he told a flabbergasted Oliver.

anonymous asked:

Hi! I was wondering if you knew what would happen in you took your helmet off in space? I'm contemplating having one of my characters do this.

Short answer: Nothing good, then death.

Longer answer: Nothing really bad for a few seconds, then nothing good, then death.

So, something has gone wrong on your space journey. You have been caught in a bad situation and have to expose yourself to space for a short amount of time. For some reason, you opened your helmet or something happened to it.

First things first: You will not explode, turn inside-out, instantly freeze, or instantly boil. You will not have your eyes bug out and the blood vessels in your face will not all pop.

Sorry, Arnie. You’ll be fine. For a little while.

From the moment you open your helmet and expose yourself to vacuum, you have about thirty seconds without anything really bad happening to you. If you are exposed to unfiltered sunlight, you will probably get a slight sunburn (pure UV rays will do that - the closer you are to the Sun, the worse it will be).

After that, things start to go bad really fast.

After about ten seconds or so, you’ll start to get some swelling of the skin (not a lot and easily survivable) and some dehydration of the eyes. Your ears will probably pop, and you’ll feel your tongue start to dry out. So far, you’re okay and will have no permanent effects - if you get back to pressure before thirty seconds or so passes.

After that, you will start to run out of oxygen, and will probably pass out at around thirty seconds. If you have some warning and are able to take several deep breaths before exposure, you can probably survive slightly longer. DO NOT TRY TO HOLD YOUR BREATH! If you do, the pressure difference will probably damage your lungs. Ask scuba divers about what happens if they hold their breath when ascending. Same thing. At this point, you’ll probably get some permanent damage - extreme sunburn, or lung damage.

After ninety seconds in vacuum, death is probably unavoidable. If you get back to pressure before then, you have a very good chance to recover.

Of course, these are just guesstimates. NASA generally doesn’t go around deliberately exposing their astronauts to vacuum. Generally.

However, it does happen. in 1965, Jim leBlanc was accidentally exposed to total vacuum while testing a moon suit prototype. In the accident, his suit pressure dropped from  3.8 psi to 0.1 psi in 10 seconds (normal atmospheric pressure is about 14.7 psi).

Luckily, it only took just over a minute to restore full atmospheric pressure to the test chamber, but people can survive at a lower pressure than 1 atmosphere. LeBlanc survived with nothing more damaging than an ear ache.

Yes, there is footage of the event, and Jim leBlanc tells you himself what it felt like.

So, make sure you check your equipment before you leave your spaceship. 

The life you save may be your own.

I don't know if you're still in the writing mood but here's a prompt if you're up for it: clark non-explicitly asking bruce out in the middle of conversations and never being taken seriously

(AN: I’m sorry this took a little longer, I’ve been working more days lately and there is a couple days between me writing the beginning of this and the end if things seem a little wonky. I hope you like it either way)

“He has to know right? I mean, it’s Batman.”

“Let it go, Bear.” Hal said not looking up from his magazine. The two were supposed to be on monitor duty, but the Lantern normal took this time to relax and maybe catch up on some sleep if he was partnered with someone reliable and there were very few more reliable than Flash. Except apparently when there was drama afoot.

“I can’t just let it go.” Barry sighed but reluctantly turned back to the monitors, far used to his friend’s routine. Between Justice League missions and Green Lantern duties, he couldn’t really complain if the guy fell asleep while working. Much. “It’s like watching someone slip on something in slow motion. It’s too late to warn them and you know it’s going to end in disaster.”

Hal snorted but didn’t object to the hyperbole. Of course Batman had to see it, they all had. It had been going on for months. Hell, maybe even years considering the two had known each other for far longer than the rest of them had.

Then again, he thought, glancing up towards where Batman and Superman were huddled over the plans for the Watchtower renovations. The guy does have the emotionally intelligence of a potato.

Supes was standing shoulder to shoulder with the Bat, a proximity that seemed only to be reserved for him, Diana and his forty friggin kids. The aforementioned Bat’s shoulders weren’t as tense as they normally were. If it was anyone else, Hal would have just narrowed it down to the years of familiarity they had on the rest of them, but the Lantern had only seen that particular extent of relaxation around the other man’s fifty-seven bat kids. Hal shook his head, turning back to his magazine and taking his own advice, letting it go.

“We need to fix the water pressure in the en-suite showers, but that can wait.” Bruce said, lens covered eyes scanning the plans as Clark nodded along. “It’s the satellite that needs immediate attention.”

“Did you see that new restaurant by the Planet earlier?” Clark asked as his friend lapsed into brief silence, most likely doing calculations in his head.

“I did. That meteor shower on Monday caused more damage than J’onn and I anticipated. Some of the panels will need to be replaced.”
“Well that’s probably because I needed to destroy an asteroid to make it a meteor shower. We should go there for lunch tomorrow instead of the diner.”

“Rosanne would stop giving you that free cheesecake if she found out we skipped out on the usual place. I can get new panels, but it might take a couple days.”

“I can loop around the planet a couple times every day until we get them. And okay, that’s fair.” Clark chuckled, thinking of the older waitress that normally took his and Bruce’s order whenever the former was in Metropolis. “Well how about we go there for dinner?” He suggested albeit hopefully.

“Can’t. Charity dinner. One that you’re covering.” Bruce hummed without missing a beat. “That’s impractical even for you, Superman. There might be a way I can get them as early as tonight, might have to involve Malone though.”

“Oh. Right, day job.” His shoulder’s sagged only the slightest bit and he raised a half amused eyebrow. “Malone has those kind of connections?”

“You’d be surprised. I’ll make the arrangements for after the dinner later. If I can get them, you’re going to have to do the heavy lifting.”

“Yeah, I can do that, B.”


He has to know. Dick thought watching Bruce and Clark crowd the monitor (Batcomputer as Nightwing had mentally dubbed it) looking over the results of the tests Bruce had ran on a strange metallic object that Clark had ‘ran into’ during one of his most recent battles. Clark’s hand rested on the top of the computer chair as he leaned forward for a ‘better look at the screen’, invading Bruce’s personal space. Rather than objecting to the proximity, B didn’t even seem to notice it. Which Dick knew was bullshit since his father figure was aware of almost everything in his environment. He was sure Clark was aware of this as well.

It was a familiar routine, one that Dick could trace back to his Robin days, when Clark and Bruce first began their uneasy truce that surcame to years of true friendship. Of course, back then he hadn’t been totally aware that Superman had been flirting with his guardian. Not until Jason had taken up the Robin mantle at least. He shook his head. At this point he wasn’t sure if Bruce was toying with the other man or if this had actually managed to evade the Batman’s noticed. Which he seriously doubted. The pattern was always the same; they did some actual work for a few hours, standing or working closer to each other than strictly necessary, then Clark would bring up a movie he was thinking about seeing (this week was the new King Kong movie, go figure) or a concert or restaurant he wanted to go check out and would casually invite Bruce along, only for it to go over the Bat’s head.

The worst part was, Dick knew Bruce was interested. He knew Bruce better than the older man knew himself sometimes. They all saw the softness in his eyes when it came to Clark, the inside jokes, the way the Man of Steel could just ‘pop by’ without getting the whole ‘my city’ speech (most of the time) anymore. So it baffled the eldest child a little. He didn’t know why he toyed with the other man like that. Maybe he decided he would lose interest, maybe he had somehow convinced himself that he was somehow a danger to the indestructible man like he had most people in his life. Maybe he convinced himself that relationships themselves were too dangerous, too distracting from his work.

Maybe, Dick thought as he watched Bruce’s lips twitch a little at some corny joke Clark had made before falling back into their neutral scowl. He thinks he’s the one being toyed with.

He shook his head and headed upstairs for something to eat, ruffling Damian’s hair as he passed him on the stairs.

“Try not to be as hopeless as them when you get older, okay?” He muttered, smirking at the confused look he got as he walked away.


Clark yawned and stretched, pushing up his glasses to rub at his eyes. Alien or not, staring at his computer screen for six straight hours had done nothing good to his eyes, or his back for that matter.

“So, even Superman gets uncomfortable in cheap office chairs.” He looked up in brief panic before his brain registered the voice. The shadows of the empty bullpen seemed to naturally surround Bruce, even when his Batsuit was traded for a nice Armani one. His lips were quirked in a small, amused smile as he approached his desk as he had many times before. “The job of an investigative journalist is never done I see.”

“Unfortunately not.” Clark chuckled, leaning back in the chair to better look up at him better. “To what do I owe the pleasure, Mr. Wayne?” He asked with a bit of a teasing grin. Bruce said nothing, just studying his face with those calculating blue eyes in a way that always made Clark want to squirm. Of course, if he did, that mean Bruce won. It became a game at some point, though he couldn’t say when, one he was almost sure he wouldn’t win. There was no winning with the Bat. He had even resigned to stop his advances, forfeit the game. He was content with being friends, that would be enough for him.

Of course with Bruce, it wasn’t that simple. Because, like most things with the Bat, the moment Clark thought he was out, Bruce changed the rules. The billionaire leaned down and pressed his lips against the reporter’s, who responded to the long dreamt about kiss immediately, cradling the back of his head, afraid it would end just as suddenly. When Bruce did pull away, he was smirking.

“Come on, you owe me dinner.”

Biosafety Levels 1-4

We’ve known that breathing in or touching infectious/infected material is probably bad since before germ theory, but it wasn’t until 1943 that our first formal guidelines and laboratories for technician separation from the infectious agent were set up. It was the 1960s before the first conference to standardize personal protection equipment (PPE) guidelines. 

These days we have 4 basic safety levels when working with biological agents: Biosafety Levels (BSL) 1-4

BSL 1 includes well-understood agents not known to regularly affect adult humans, and which present a minimal level of hazard to the technician. Canine hepatitis, non-pathogenic strains of E. coli, and other non-infectious bacteria. Aside from standard healthy-living procedures (washing with soap etc), laboratory equipment is decontaminated via autoclave between uses, protective gloves, and sometimes protective goggles are required.

BSL 2 includes many of the milder infectious diseases that we know about, such as Salmonella, measles, mumps, MRSA, C. difficile, and hepatitis A, B, and C. These are sometimes serious illnesses, but are not easily aerosolized in a laboratory setting. When aerosols may be formed, biological safety cabinets are used, extreme care is taken with sharps, access to the laboratory is limited during work, and all technicians are trained in pathogen handling procedures.

BSL 3 includes dangerous pathogens that can cause potentially lethal infection, such as Yersinia pestis (black plague), rabies, SARS, tuberculosis, tularemia, and yellow fever. Laboratory personnel have specific training in handling pathogenic and potentially lethal agents, and are supervised by competent scientists who are experienced in working with these agents. All procedures involving the manipulation of infectious materials are conducted within biological safety cabinets, specially designed hoods, or other physical containment devices, or by personnel wearing appropriate personal protective clothing and equipment. The laboratory usually has special engineering and design features, such as restricted access, double-door entrances, and sealed penetrations. BSL 3 laboratories are sometimes called warm zones.

BSL 4 includes the most lethal and exotic agents that there are no cures or vaccines for, such as Ebola, Lassa, Argentinian hemorrhagic virus, and smallpox (smallpox for its extreme virulence, despite its vaccine availability). When dealing with biological hazards at this level the use of a positive pressure personnel suit, with a segregated air supply, is mandatory. The entrance and exit of a level four biolab will contain multiple showers, a vacuum room, an ultraviolet light room, and other safety precautions designed to destroy all traces of the biohazard. Multiple airlocks are employed and are electronically secured to prevent both doors opening at the same time. All air and water service going to and coming from a biosafety level 4 (or P4) lab will undergo similar decontamination procedures to eliminate the possibility of an accidental release. Agents with a close or identical antigenic relationship to biosafety level 4 agents are handled at this level until sufficient data is obtained either to confirm continued work at this level, or to work with them at a lower level.

Members of the laboratory staff have specific and thorough training in handling extremely hazardous infectious agents and they understand the primary and secondary containment functions of the standard and special practices, the containment equipment, and the laboratory design characteristics. They are supervised by qualified scientists who are trained and experienced in working with these agents. Access to the laboratory is strictly controlled by the laboratory director.

The facility is either in a separate building or in a controlled area within a building, which is completely isolated from all other areas of the building. A specific facility operations manual is prepared or adopted. Building protocols for preventing contamination often use negatively pressurized facilities, which, even if compromised, would severely inhibit an outbreak of aerosol pathogens.

BSL 4 labs are hot zones.
