The actual YSK.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must begin with YSK.
All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.
Rule 2- Your post body text must include the reason WHY YSK:
In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- The majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.
Rule 11- Posts must actually be true:
Disinformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban. This also applies to filing reports: If you continually file false reports YOU WILL BE BANNED! We can see who reports what, and shenanigans will not be tolerated. We are not here to ban people who said something you don't like.
Rule 12- Linking directly to a video as a source is not acceptable.
Video only posts are responsible for an outsized portion of rules violations. Your post must contain text and meet the requirements of the previous rules.
Rule 13- If you file a report, include what specific rule is being violated and how.

The actual YSK.
To be fair, do they carry around any sort of badge? Could have seemed like a crazy person to- oh it was in Austria, not New York
Regular guy seeing fire: “this is my chance to lie about being a firefighter”
I doubt that happens often.
Tweakers and the mentally infirm. There is also a type of character who just compulsively lies about things, especially in the worst situation.
I can see why some people wouod be unwilling to trust the advice of "run towards the fire," regardless. Maybe the firefighter took the time to explain the ohysics briefly, in which case we have 12 survivors who understood the physics (thus could trust him) and a couple dozen or so who were less physics literate. Science saves lives!
I’ve known compulsive liars . They aren’t good at lying during emergencies. When people panic they have a hard time opening up doors without instructions. People don’t make up lies on those situations. Atleast it’s very unlikely. Tweaked or not.
As for mental illness I guess if the person already believes themselves to be a fire fighter because of mental illnesses they might continue that belief on a fire. But again that has to be pretty rare.
"I'm a retired firefighter! Quick, everyone eat your Metro cards!"
"i'm a retired metro driver. everyone strip down and grab a handful of this petroleum jelly!"
am current firefighter. follow my directions but don’t follow my lead. odds are i’m nerding out and looking for the fire.
Direction to go in case of a public transit fire is probably highly context dependent. The real lesson here is to follow instructions of trained emergency response personnel

We just went through CoViD, like a week ago (a week, right? It also feels like a million years, so I'm not sure). We found that, largely, MANY people didn't follow the sane, simple advice to lessen the load on trauma centers -- "Do like a billion people in china do every day, and wear a thing on your face". And the defiance-as-religion types didn't die fast enough.
NO ONE's gonna listen to an authority on this either. I'd want them all to run into the zombie horde and stare them down or something like hillbilly tough guys, but I need someone to farm the bran in my good, good, whole-wheat shreddies.
a very shitty Team sport
Perhaps worth pointing out that the 12 who survived did not run into the fire. They broke a window and went downwards past the fire. From Wikipedia:
Twelve people from the rear of the train broke a window with a ski pole and, advised by an escapee who had been a volunteer fire fighter, escaped downwards past the fire and below the smoke.
I'd never taken the time to realise firefighters have to learn about physics-nonsense for their line of work. On top of having to stay really fit? That's tough
That guy would have evaluated the size of the fire, the progression of fire over 30s, 1min, and 2min, danger levels from direct-flame, radiant-heat, and smoke-inhalation, effects on structure, in about a second.
Determined the best course of action was to get below the fire, in another second.
Fire travels faster uphill, smoke fills available space from top down.
Most people understand fire in a controlled situation, such as campfires, hearths, or bonfires.
If someone seems to understand what that uncontrolled fire is going to do, listen to them.
Yep. Covid ruined my belief in sanity. If it were a zombie apocalypse there would be people saying “I have a right to be eaten by zombies!” While they just end up making many more zombies.
It would be fine if they asserted their right to get eaten by zombies. The problem is that they decide they have the right to let a zombie loose in middle of the haven.
The key part of fire behavior to understand here is how exactly a fire goes about consuming oxygen and exhausting heat and smoke in an enclosed space.
Fire will always need to pull oxygen in, and push heat and smoke out. Oxygen and the cooler air it makes up will always be pulled in on a lower plane than the heat and smoke it pushes out, which as many people know rises. The way this affects the space you’re in and therefore where you want to be (Besides you know, out) is dependent on how many openings to the outside space there are and where they’re located.
If there are two or more openings to the outside space at different elevations, the fire will pull the cool oxygenated air in the lower opening, and push the heat and smoke out the upper opening. This is known as the chimney affect, and as you may have guessed from the name is how fireplaces work. This is why you can have a fire inside your home without dying from smoke inhalation, all the smoke and a lot of the heat is going straight up and out of the chimney, as the fire pulls oxygen in from your living room. This creates a negative pressure in your living space that prevents the smoke from emptying into it, and you just keep the horizontal radiant heat.
If there is just one opening, the fire will have to share that opening between those two functions. The lower half of that opening will be pulling cool air in, and the upper half will be pushing heat and smoke out. If you saw this in person you can actually see the exact line between these two things happening which is called the neutral plane, and you want to stay below it at all times.
There is however a danger here, which is that a single opening like this, often a set of basement stairs in a house fire where the fire is in the basement, allows access down to where the fire is by firefighters, provided they stay below that neutral plane, but only as long as that remains the only opening. Firefighters can and have died fighting their way down basement stairs meanwhile a small basement window below grade is broken either by the pressure generated by the fire or even a fellow firefighter breaking it for ventilation without due regard for the firefighters inside. This turns that window into the point the cool air comes in and the neutral plane on the stairs disappears and the entire staircase becomes a chimney of superheated air and smoke top to bottom, likely killing anyone who remains on the stairs.
So it’s really about getting under the fire, even if that means going through it first.
Specifically, you want to be up wind of the fire, and it the fire is creating that wind in an inclined tunnel that might involve heading down, through the fire. Funicular railways and stairwells could both be places that's necessary.
No. Structures on fire tend to collapse, and then you have fire falling onto you. That sounds like a bad idea.
It may either be that or waiting at the top of a burning structure thats going to collapse?
once you get to the top of the structure, evolve some kind of hot air balloon to float to safety.
Actually yes. The thing is that falling onto the fire isn’t any better than the fire falling onto you. You always want to be below where the fire is because that’s where the fresh cool air is, and where the heat and smoke is not.
I mean you don’t want to go through it, that will just kill you. But staying below the heat and smoke it’s generating is always a good idea.
I guess if you ever find yourself owning the high ground to fire this is useful, or find yourself in a tube whose bottom is aflame.
Might also be that your only way out of a room is through a burning doorway. Gotta find a bottle of water and Riddick that shit.
