Beg pardon, but I was wondering what kind of survivable injuries could be expected from someone having a building fall on them. I presume that in the immediate term you’d have crushing injuries from large pieces of building fall on them, but what kind of crushing injuries would be most survivable? I also assume that there would be deep penetrating trauma from exposed rebar, but in what parts of the body could someone have rebar in them and survive? Thank you for your time and attention.eliasraine
It depends on how flexible your definition of, “survivable,” is.
The big threats from having a building drop on you are: Something you need gets crushed. Think, your head or chest. Lose those, and you’re done. Limbs are negotiable. Getting run through by rebar is a threat and can lead you to bleed out, but this is more forgiving than you might expect. Search and rescue.
Because of the rough surface, rebar has a tendency to bind into wounds, sealing them against bleeding, with a couple major caveats. You do not want to aggravate the wound, by moving, you do not want to pull it out. This means, if you take a chunk of rebar through a limb, it probably won’t kill you on its own. That said, this is a major risk of infection, and getting impaled through the torso is extremely dangerous, even if you don’t bleed to death. Also, if you do struggle to move around, it’s entirely possible you’ll work the wound lose, and bleed out that way. Especially if you’ve taken it through the leg. Finally, even if you do survive, it will result in some serious deep tissue trauma. Figure a leg or arm that’s been run through will never be quite the same again.
Getting crushed under concrete, or other reinforced structures are a similar story. If it’s a limb, it can potentially hold the artery closed, acting as a kind of accidental tourniquet and save your life. The limb itself has been reduced to pulp, but you can live through it. Obviously, having your torso or head crushed is going to be less survivable. Though, having the lower torso crushed is particularly nasty, as it won’t result in immediate death. There’s also some nasty permutations, where simply cutting off the flow of blood to a limb for an extended period of time can do horrific things to you when blood flow is restored, even if the limb itself is mostly intact.
Note, in both cases above, this is only buying time. Someone who’s had a chunk of rebar run through an artery will still bleed to death, but they may have hours instead of minutes. Similarly, if your thigh has been pulverized, the weight will keep you from bleeding out for awhile, but it probably won’t stop the loss of blood entirely.
After surviving the initial collapse, a major threat is asphyxiation. This can occur either because there’s insufficient access to breathable air (pulling fabric over the mouth and nose as an improvised mask can help), or because of weight on your upper torso interfering with breathing (without it actually crushing you.)
A major danger is the search and rescue teams who come in to find survivors. This is for a couple major reasons. Moving the ruble has a real risk of causing the debris your under to shift. This could either allow you to start bleeding again, or it could crush you. The second major threat is once they’ve found you. Successfully extracting victims from a collapsed building is dependent on having on-site medical attention. Again, any of these injuries that won’t kill you on the spot are survivable with medical attention. Now, the good news is that most well trained Search and Rescue teams understand the things I just outlined, and have sophisticated tools for finding survivors, and understand the need for on site paramedics.
Also worth knowing, the odds of survival start out pretty good, but drop off sharply after the first day. So, it is possible to be trapped under the rubble for up to a week (depending on injuries), but if your character has suffered serious trauma, the clock is ticking, and without rescue, and medical attention, they will die.
So, this is survivable, but it’s also going to be a life changing moment. It can get pretty horrific before it kills you.
