Recently I fell from a ladder, second floor window. I was on the concrete before I knew what happened. Fractured the Tib in my right ankle and fractured my left heel. No able to walk yet.
So, I had thought that if I had to get out of a 2nd floor window (cornered by a rampaging Chimp) I could drop/roll and I would be ok, now I am not so sure. What do you guys think?

When I was a Ironworker in NYC, one of my foreman's nickname at the time was "rubber".



He fell off the open steel and fell 3 stories onto the steel decking below, bounced a few times, and was up walking it of in about 20 minutes.



I saw it with my own eyes, and couldn't believe it.  



I've seen falls from just 10' result in compound breaks and bones sticking through the skin with massive amounts of blood loss.

I work with a guy who fell about 18 feet on construction site once. Landed flat on his back.

Although it knocked every last bit of air from his lungs, and hurt so bad that he thought he was going to die...

he sustained no injuries whatsoever from the fall.

The ER doc was stunned.

Too many factors.

I did a two-story fall and instinctively tucked and did a PLF and walked away with a bruised pride.

depends on your # of HD


1d6 points of damage per 10 feet fallen, to a maximum of 20d6.

If a character deliberately jumps instead of merely slipping or falling, the damage is the same but the first 1d6 is nonlethal damage. A DC 15 Jump check or DC 15 Tumble check allows the character to avoid any damage from the first 10 feet fallen and converts any damage from the second 10 feet to nonlethal damage. Thus, a character who slips from a ledge 30 feet up takes 3d6 damage. If the same character deliberately jumped, he takes 1d6 points of nonlethal damage and 2d6 points of lethal damage. And if the character leaps down with a successful Jump or Tumble check, he takes only 1d6 points of nonlethal damage and 1d6 points of lethal damage from the plunge.

Falls onto yielding surfaces (soft ground, mud) also convert the first 1d6 of damage to nonlethal damage. This reduction is cumulative with reduced damage due to deliberate jumps and the Jump skill.

when i was in tae kwon do years ago my instructor did it from a 2 story balcony with no injurys, no scratches...

its doable from2 storys BUT i would say only with proper training...

Ninja training will prevent all injuries associated with falls.

A few weeks ago security was chasing a guy that had broke into a car here at work. The dude jumped off the 3rd floor of the parking garage and hit the ground running.

He got away.

IIRC the max height you can fall, landing in deep water, without injury is 40'. But if its cold as fuck, you'll drown due to the shock.

Depends on a lot. Your weight, how hard the ground is, etc.



Google "PLF" or "Parachute Landing Fall" to help minimize injury in any future falls.

 It is higher than that. I'm almost sure.






Here is a guy who jumps more than 4 times that...








I remember around a hundred.

I refuse to climb a ladder further than I am tall.      saw a guy with 30 years experience with an electric company lineman fall 2 stories from a ladder.  The sound of him hitting the ground still nauseates me thinking about it .   Broken wrist, compound fractures to his lower left leg.  Right ankle shattered.  

 Trying keep him lying still and not go into shock was 1 of the most trying times I've ever had to deal with.

  Every time I see the scene from No Country For Old Men   where the kids are looking down at the broken arm.   "Look at that fucking bone"   was my thoughts that day

   nope, you couldn't pay me enough to hang off a ladder  more than 6, 8 feet off the ground

 


Link Posted: 3/20/2009 7:08:32 AM EDT
It depends on how you land.

I saw a guy fall 2.5 stories and land flat on his back- no injuries.  I saw another guy step off a curb wrong and break his ankle.

In Post Falls ID, you'll regularly see drunk kids jumping off cliffs twice that high.  The water is very cold.

It's all about the landing.

Too many variables for a simple answer.  Weight of the person, their physical condition, their training, how they land, luck, etc...
People have fallen from 3-4 stories without serious injury and others have fallen 6-10 feet and been killed.
I make it a rule not to jump from anything higher than I am tall.

If anyone wants to find out, I'll hold his beer!
Link Posted: 3/20/2009 7:27:56 AM EDT
I learned from "The Matrix" and "Wanted" that you don't want to roll or PLF, you need to land on one knee, one foot; with your head bowed in a dramatic pose.  That's how you land when you jump across the street or off of a roof.
Link Posted: 3/20/2009 7:29:55 AM EDT
Foot pursuit from a stolen vehicle crash, and I vault a five-foot cinder block wall my suspect just went over. It turns out to be thirteen feet down to the alley on the other side. Shattered calcaneus (heel bone), multiple ankle fractures; got retired two years later and now have a neurostimulator sewn in my hip to shut down the bad signals from nerve damage in that foot. Hence my screen name.

BUT...suspect was located by the puppy dog, who removed about two-thirds of his bicep when he decided to fight the dog.
Link Posted: 3/20/2009 7:34:01 AM EDT
Depends on your technique.  I once heard a story about two guys that were working on lift hanging lights in the grid of a theater when the lift fell.  One of them was a skydiver and executed a Parachute Landing Fall, he walked away, the other guy was killed.

ever watch any parkour (sp?) videos?  Those guys fall 10-20 feet all the time, hit the ground and roll, and get up and keep running.
Link Posted: 3/20/2009 7:46:31 AM EDT

I fell 25-30 feet one time, landed on my feet and tucked/crumpled/rolled.

I had no broken bones but I strained and sprained and bruised everything.

-p.

Jumping (controlled) is not the same as falling (uncontrolled).

I dropped 18 inches to produce a massive tib-fib fracture when that foot landed on a ladder rail.

I can jump at least 8 feet without injury (still) but it used to be higher.
Carrying metal on the fib limits needed flexing.


Many years ago i did jump off a bridge over 90 feet to the water for a rescue.
Just plunge in feet first arms tight to your sides.

I have heard that 50% of hunters in tree stands who suffer falls from 20 feet or more are fatal.

40' is for a belly-flop or uncontrolled fall, not a dive.

Depends on how you land. Ladder gave out and I took a dive from just under 2 stories (probably about 16-18 feet) face flat onto a concrete sidewalk. Got cut up bad, but nothing broken. If I landed feet 1st or with arms outstretched, they would've been broken for sure.

My 89 year old grandfather fell out of a deer stand flat on his back from about 11ft. up  He is doing just fine with no pain, and oh yeah.  He fought in WWII in Italy, bronze star.

I've jumped from a second story without hurting myself, but it's NOT something I would recommend.  You've got a fair chance of an injury if you aren't in really good shape. I've also jumped out of a car into grass at 30mph without injury.  You'd be surprised how much it can hurt to jump from a moving vehicle.  My roommate got a pretty bad concussion at only 25mph in grass...he didn't roll as well .

I heard it's the landing that gets you though.

The general rule in EMS is a fall of three times your height or greater gets you a ride to the trauma center rather than a normal hospital.
Link Posted: 3/20/2009 10:33:52 AM EDT
It isn't the fall....it is the sudden stop that will hurt your ass!

It really depends on what level ninja master you are.

I once fell 18' off a ladder.  Only the ladder caught on a edge on the way down.  So I landed all twisted up in the ladder.  No injuries at all, but it hurt real bad.

You can fall as far as you want without breaking bones.........just don't hit the ground.

There was a guy who survived a fall from a B-17 at altitude over Germany during WW2. IIRC, he was a tail gunner, and couldn't reach his parachuet due to fire. He jumped rather than burn. He hit tree branches, then snow. The Germans found him, and at first treaded him bad becuase they thought he was lying. When they confirem his story, they treated him very well.

When you fall from a height like that, your impact speed will be somewhere betweeen about 100 mph and 200 mph. If he had his arms and legs out, and he was a skinny, light guy, his terminal velocity could have been on the low side.
Link Posted: 3/20/2009 11:07:31 AM EDT
I prefer not to find out.

Falling more than about a foot in a poor harness can cause major injuries.
Link Posted: 3/20/2009 11:08:23 AM EDT
It's all on how you fall. You can break bones from a five foot drop, or walk away from a 20 foot drop
