Adrenalin Harness failure
Hey all,

I heard about a French guy had his chest strap "explode" during opening and he almost get out of his harness.
Some of you have more informations about this ?

Yes, but from what i know :
- He is not a skinny guy (i know him Cool)
- He used his chest strap to abseil down a couple of time !!! witch is really NOT good and may be the main reason of failure ...

When using your rig to abseil down, never use the chest strap, but leg straps, or a light mountain harness ... way better !

We are waiting for Jean No conclusions ...

It definitely doesn't help :-) Does Adrenaline still make their chest straps out of a single piece of webbing? I never liked that particular design as it has been known to fail in the past.

Re: [Indian64] Adrenalin Harness failure
About the stitching failure that happened on a ZAK last week: we just got the harness for inspection.Jumper close to the weight limit of the equipment (110kg), going very fast on opening, and with very hard opening. The jumper landed without any problems.

Some abseils, made directy on the chest strap, started to broke the thread on the chest strap (the forces pull on one of the peak of the stitching and start thread breakage there). The extremely not symetrical hard opening (large hematoma on the body) finished the job.
this is first conclusion after inspection. We are going to make additionnal test to confirm it. Of course, we will share with community the results that will comes out, and also some recommandations about abseils and rope used with the Base harness.

Re: [jeannoel] Adrenalin Harness failure
Is there any indication of extreme asymmetry in the opening? Signs of the tearing occurring from a diagonal pull on the chest strap? Reciprocal damage on the other side? Stress on one side of the harness or canopy or brusesing on the jumper?

Most chest strap damage I have seen has been associated with extreme asymmetric openings. And as I recall some of the skydiving manufacturers, Booth as an example, have had problems passing harnesses do to that. It's a common problem trying to do testing with Dummies.

Is it a joke ? It's BASE jump we are doing. Maybe people deserve a better conclusion that just it's not our fault, it's the jumper fault.. which it's that your post is saying. I'm one of your customer, I jump Hybrid and ZAK and I'm waiting for better explanations than that.
Also the fact that I believed, like many, that you manufacture your harness containers in your facility in France which it's absolutely not true. Look like the harness are manufactured somewhere in the East Europe... Shouldn't be written on the equipment somewhere that it's not made in France but made in random factory somewhere ?

Let me get this straight:

A jumper uses a parachuting harness as a climbing harness and the harness fails because:

a) it was damaged by being used for something for which it was not designed; and

b) the jumper couldn't deploy in a stable body position...

and you think that is the fault and responsibility of the manufacturer?

What are you -- a lawsuit-happy American?

Moreover, you appear to be a troll with an agenda. I notice you registered here the same day you made your post, and you described a chest strap as "exploding." Really? Did the guy hide a Cypres charge in it? Semtex? C-4?

Bottom line: Bad things can happen when you use any equipment for a purpose for which is not designed. It's now clear to me that this whole thread is a setup to attack this manufacturer, nothing more.

It's the french forum.. Look at the pics on the last post. It's what happened after only 1 abseil and 60 jumps...
Sorry but I don't think it's a jumper fault... and if your chest strap can't take an abseil don't jump with your rig... The sewing point are supposed to be more stronger than the webbing used for the chest strap. Other manufacturer said than abseil don't have anything to do with this... Many of them agreed on that... That was people where saying in Lauter last week.
It's my point of view, my 2 cents.. but look like others thinks like me...

Re: [Indian64] Adrenalin Harness failure
Dear unknow,

Like i said, we are making some test to make sure we understand well why this happened. Pull test, thread examination,....can not be done in 1 day. Our conclusion will comes out very soon.
Yes we are manufacturing some of our equipment in europe, in a ISO 9001 certified paragliding manufacture.
But You are welcome to see the workers manufacturing harness 10 hours/day in our shop in chamonix

Re: [jeannoel] Adrenalin Harness failure
Hi Jean Noel
Thanks for building great equipment which I can jump without having to worry about when I jump. Unfortunatly our Sport has involved in a bad Way and new jumpers have no idea what base jumping is about. They think after watching a few youtube vids that they can buy some equipment and they don't have to take any self resposability on what they are doing... Base Jumping is not like Golf, what we do is in our responsability! We need to have some basic experience in rigging before we jump! I am glad that we have equipment manufacturars like you, Robi or Stane who carefully test the equipment before the sell it. And I am a bit disapointed that there are still (and every day more) ignorants in the sport who are so degenerated that they forget that Base Jumping is not table tennis (this is not against the person who had the incident but to those who did not realize that base is not just something where you can buy the equipment and think thats it...) when I buy something I check it because I jump it and if it fails I die. And it is built by people...

Indian64 wrote:

reading the information about this mishap it pretty much sounds like it was the jumpers fault....

but you seem so sure about this so i assume you have some deeper insight, are a rigger and maybe you have you been there and seen the opening close up? did inspect the harness prior to the jump?

Indian64 wrote:

then you probably should stop jumping, because with a heavy guy and a bumpy rappel you can fuck up and damage pretty much every type and brand of base container easily. (and skydive rigs aswell)
it is a base rig, it is not meant for climbing, rappeling, or anything other than jumping off stuff! and especially its cheststrap is not built for taking that kind of load in that angle...

Indian64 wrote:

congratulations for reciting stuff that you clearly dont understand. the joint on the cheststrap on this rig was for sure as strong as the webbing, when load is applied in the right direction!

ah, yeah, you found some other jumpers that support your point but would like to stay anonymous?


you know what i think?
you just found out that even new, commercial grade base equipment still requires you to use your brain (not intended as insult to the jumper that wrecked this rig, just trying to make a point here)!
and you got scared by this so much because you didnt think of this possibility before and deep down you know that youre kind of in a dangerzone because you seem to lack some knowledge. so you attack the manufacturer, pushing all the responsibility over to him, to make yourself feel safer/better.

and on the other side of this post was jean noel that replied to the posts (of which some sounded quite hostile) within a few hours in a very friendly way giving a logical explanation to what happened.

Re: [84n4n4] Adrenalin Harness failure
some math for those non-riggers:

vector angle pull forces can give an incredible mechanical advantage on the anker points. at a degree of 90°, it's 1.5 times the force on the ankers of the weigt you pull. at a degree of 180° (witch is only theoreticly possible), you would even have an independend force on the anker points.

check the pic and try to understand first before you start to pick on manufactures...

Re: [elex] Adrenalin Harness failure

Read the fucking tailpocket

In there you will find all the helpful advice one can find..

If you don't agree then go play badminton that is tried and tested with 100 percent plastics..

Re: [MBA-PATTO] Adrenalin Harness failure
Yeah I register to start the post so what ??

As adrenalin customer I asked some questions that JN partially answered and will completely soon after the testing is finished. I'm happy with his answer for now.. Do you see me pushing to far ?... No...

It's a major incident that occur and hopefully the guy is not dead. But if he was dead, what would you said to the family ? Read the fucking stickers in the Tail pocket ?..

Also, I'm sorry guys but I don't see myself playing with death every time I jump. I trust my equipment and when I spent $3000 for a full system, I'd like it make the job...

So instead of get interest on my balls we should try to understand what really happen. It can be jumper position, it can also be cause of the abseil, but imagine a minute if the problem come from thread quality problem... It will not be adrenalin fault or neither JN, still is your rig ok ?

You might have the best intentions in the world, but your tone and attitude is just bad.

Build your own equipment, stop whining... basically and politically incorrect: eat shit and die..

The responsibility for jumping is always yours, the responsibility for the equipment you use is always yours... There are great manufacturers out there, AdrenalineBase one amongst many, but this is basejumping, with all its beauties and horrors. If you're not happy with your bought equipment, build your own. Take a blue IKEA bag and put your shit in there.

Maybe many of your comments are "lost in translation" and the tone just sounds harsh while you're the nicest dude in the world.

Re: [Indian64] Adrenalin Harness failure
INDIAN64

knowing the base rig(canopy and H/C) is the basic part of jumpers knowledge in order to enjoy BASE game for long time.

You fail there and better start learning so we don't have to see in the future that you aso fail in some other seegments as well.

BASE equipment is better than ever before and this is main reason why we have the lover rate of incidents i the sport this days.
if the jumper overall knowelege and skill would be as it was before 6-10 years the rate of incidents would be way smaller too.

for the end...
take well known skydiving rig like javelin, micron, mirage and go for head down 20 -30 sec and pull reserve .... youll be surprised ... and this is certicified rig made in usa and tested 10000 times and the has double folded MLW and chest strap...

Re: [robibird] Adrenalin Harness failure

I understand what you are saying Robi but if the chest strap was doubled then it would wrap around the lift web and terminate at the opposite end. So if the stitching does fail at least the chest strap won't come off completely as it is wrapped around the lift web.

Re: [Indian64] Adrenalin Harness failure
Poor Indian64 who’s being publicly assassinated just because he wants to understand why a harness failure happened ! Unsure

Yes, basejumping is about selfresponsability... that’s why, as an Adrenaline customer, I also want to know why this cheststrap broke suddenly, so I will know if I can trust my equipment or not, and decide if I jump it or not. That’s what I call selfresponsability !
I don’t think that closing the eyes on an incident and saying «Yeah ! Basejumping is hardcore so lets say nothing and deal with it» will help to solve problems. Wink

I was jumping with the guy who had the problem. He had a nice new and perfect rig with 0 scratch... and suddenly a chest strap explode (no semtex, no C4 Laugh ... but the cheststrap was litteraly blown out). Which is surprising with a harness who have 60 jumps and just one reppeling !

So maybe it’s Adrenaline fault... maybe not.
Maybe it’s just a «random shit» which happens once every million jump so we don’t need to worry about it... or maybe there’s a problem that can be easily corrected so we all jump in safer condition.

Personally I’m still jumping my Zak and I love it... but I’m curious, and I’m waiting for a solid and argumented conclusion so I know if I can really rely on my equipment... Not because I’m a «new jumpers who have no idea what base jumping is about»... But because I prefer to be informed about what I have on my back.

So let's stop fighting on a forum... go jumping and drinking beers while Jean Noel is working to know where the problem comes from ! Smile

I rarely try and sound serious on this forum. And I don't mean to offend you with my bluntness, but if you can't inspect your own gear and decide if it is airworthy or not then maybe you're not responsible enough to own BASE gear in the first place. You should be able to identify if the proper thread was used with a glance. You should be able to identify the condition of the webbing, stitches, and continuity wraps with a glance. And you should be able to identify the condition of the hardware, and any red-flags (dents, spider cracks, excessive abrasions, etc.) with a simple glance. If you have to ask about something as simple as the condition of your chest strap, and bring into question the reputation of one of the many reputable gear manufactures who has done you a favor by assembling your gear for you, then maybe sell it for the cost of a riggers handbook, study up, then you can attempt tto make suggestions instead of just empty questions. With all due respect, of course. Smiley faceSmile lol brb lmfao wink faceWink ttyl







Personally, I think it would be rad if manufactures only sold the patterns and harness webbing pre-cut, and you had to assemble it yourself. That would remove so much liability from the manufacture, and save those who like to build their own gear but are to lazy to make their own designs a buttload of time. Plus it would probably steer away some of the people who make jumps before they understand what they are jumping.

Re: [OuttaBounZ] Adrenalin Harness failure
I agree that everyone should know how to inspect his harness, and believe me : I do it regularly.

But this one was NEW and there was NO SIGNS of weakness in any part of the harness ! NOTHING could visually show that it was going to break !
The stitches who broke looked in perfect condition just before breaking !
So we should know if :
-People more than 100kg should loose weight before jumping a harness
-Adrenaline should change is sewing thread provider
-It was just a random error and it can be corrected

There are hundred of possibility and I don't know which one is true.... but it's interesting to know where is the truth. Saying "Shut up, it's jumper's fault" is not true, and is not helping to push the sport further

if he/you would be out for learning, he/you should get off the net, grab your zak/hybrid and think of why and how this could have happened, attach a rope/carabiner to the cheststrap and load it a bit and think again.
he/you are attacked, because of the hostile way of posting that directly attacks the reputation of manufacturer.


david.l wrote:

jean noel said to have a closer look, reproduce this incident, and will provide info on this aswell as how to best use a base harness for rappeling. thats pretty rad.

youre wrong here, you should have enough knowledge to at least know how something like this is possible.

so finally to add some value to this long rant, for the ones that still dont get off their computer:

the cheststrap assembly with 1 layer of ty8 is perfectly fine and strong enough, although the double layered is stronger, but also would be wrecked.
this shit can happen when force is applied in the wrong angle. if you rappel on your cheststrap the load is not put evenly on the 3-point that holds the cheststrap since webbing is flat and wide. so if you pull it upwards the upper edge is going to be slack, while the lower edge of the cheststrap is tight and actually bears the load, delivering it directly to the very single stitch on the bottom inside of the 3-point. 5 cord holds 40lbs, so for 1 stitch lets say that would (optimistically be) 2*40lbs. so all the load is held by only 1 stitch thats gonna break at 80lbs, and then you put a 110kg guy on that setup.
still any questions how just one single rappel can seriously damage a harness?

Your explanations and pictures are clear and logical. Nothing to answer about that.

Concerning the rest of your answer : I didn't attack or offend anyone. I just don't like the comments who says "It's 100% jumpers responsability so we should stop talking about it"
Of course it's jumpers responsability when they jump with a rig... but when there's a problem, it's normal to give a feedback to the manufacturer and wait for an answer.
If the answer was obvious, Jean-No would have answered "It's the reppeling"... But he didn't, so maybe there's more interesting information that we should know

im verry sorry for accusing you for using a fake profile. i appologize. if you want me to i can delete that part of my last post.

yes, it is understandable and right to ask why and how this could have happened, but op's tone was really rude in my eyes.
despite this being the (likely) case of this very incident or not theres something to learn about rappeling on cheststrap.
the main point i wanted to transport is that i think that while the manufacturer works on a proper investigation, one could also use the time to think and play around on a rig to see whats going on ther and why rappeling that way is bad, since it seems like some people are quite surprised that something like this is even possible.

so im really sorry if i offended you, i didnt mean to.

Re: [84n4n4] Adrenalin Harness failure
Hi all,

Sorry for my broken english but it's not my native language. I'm not French too even if I also speak french.

Sorry also if I'm not the old school base jumper that know everything about my equipment.. I'm new in the sport, I don't know nothing about rigging like many other jumpers.

I'm not trying to attack manufacturer neither Jean Noel, that I personally don't know. And even if my posts were see as rude, as myself business owner I can understand that the situation is probably hard for Adrenalin. But as a customer I have some questions...
Also when I eared that Adrenalin do not manufacture their harness container, but that the harness containers are completely manufactured somewhere in Europe and Adrenalin job in that is just to control the manufacture before shipping to customers. I din't liked it, because as a customer I bought Adrenalin rig first because I like them, quality and shape, and also because I though like many of us that the rigs were made 100% in Chamonix. So I just explain my feeling..

Thank you 84n4n4 for your explanations and pictures, it helped me to understand a bit more the problem.. My question after this is : Why manufacturers still use these sewing technics if they have a week point. I climb a bit with my wife and when I look at my harness the sewing are completely different.

Have all a nice week end and Jumps !

First of all. Not every basejumper is a rigger and has the knowledge to do the inspections you mention. This situation is getting worse with the big amount of newbies (nothing wrong with that of course) Secondly, you should be able to trust your gear up to a point. And thirdly, you don't inspect your gear 100% before every single jump, especially if it is relatively new as this one. IMHO, you have to see all this into perspective.

And I don't mean to offend you with my bluntness, but if you can't inspect your own gear and decide if it is airworthy or not then maybe you're not responsible enough to own BASE gear in the first place. You should be able to identify if the proper thread was used with a glance. You should be able to identify the condition of the webbing, stitches, and continuity wraps with a glance. And you should be able to identify the condition of the hardware, and any red-flags (dents, spider cracks, excessive abrasions, etc.) with a simple glance. .

First of all. Not every basejumper is a rigger and has the knowledge to do the inspections you mention. This situation is getting worse with the big amount of newbies (nothing wrong with that of course) Secondly, you should be able to trust your gear up to a point. And thirdly, you don't inspect your gear 100% before every single jump, especially if it is relatively new as this one. IMHO, you have to see all this into perspective.

Hi Jean Noel
Thanks for building great equipment which I can jump without having to worry about when I jump. Unfortunatly our Sport has involved in a bad Way and new jumpers have no idea what base jumping is about. They think after watching a few youtube vids that they can buy some equipment and they don't have to take any self resposability on what they are doing... Base Jumping is not like Golf, what we do is in our responsability! We need to have some basic experience in rigging before we jump! I am glad that we have equipment manufacturars like you, Robi or Stane who carefully test the equipment before the sell it. And I am a bit disapointed that there are still (and every day more) ignorants in the sport who are so degenerated that they forget that Base Jumping is not table tennis (this is not against the person who had the incident but to those who did not realize that base is not just something where you can buy the equipment and think thats it...) when I buy something I check it because I jump it and if it fails I die. And it is built by people...

Re: [Indian64] Adrenalin Harness failure
 

Thank you 84n4n4 for your explanations and pictures, it helped me to understand a bit more the problem.. My question after this is : Why manufacturers still use these sewing technics if they have a week point. I climb a bit with my wife and when I look at my harness the sewing are completely different.

they are different because one is a BASE rig for jumping and one is a harness for climbing. maybe read 84n4n4's explanation again

Nothing stopping ya from paying the manufacturer to custom rig your chest strap as a hardpoint. Personally I would not want to pay extra to have that as a stock option.

The job of the chest strap is to keep you from falling out of your harness. From a design point of view, that is very different than what you are asking for-- which is something that can support your weight. The location and orientation of the strap is, I suspect, not optimal for doing both jobs efficiently. Basically, there are technical reasons why it's impractical to do both... well.

The reality of gear design is that every piece of gear will have a weak point somewhere. This is BASE, where we are responsible for understanding our gear. I do not know what country you are from but there is an unfortunate reality in the USA that we sue the shit out of others, because we fuck up and try to blame someone else. That is why the original Cessna corporation went out of business-- it was sued to death because unqualified pilots didn't know what they were getting into, and they kept crashing airplanes they shouldn't have.

Do you want to even start to go down that road, where gear manufacturers are liable for the customer's negligent misunderstandings? It's a reasonable question, but there's only one answer in my book.

Re: [Colm] Adrenalin Harness failure
Spot on Colm!
I will give an example as a rigger and engineer.
I sew a 3pt diamond stitch intersecting at 90 deg. to the MLW. It will look like an "H". The horizontal is to keep the parallels from spreading in the H. All point loadings are dealt with by the 3pt diamond stitch. An east and west between 2 north and souths. But, one wants to put a different force vector on it. So now instead of an "H", One has a !^! creating point loadings on the 3pt diamond stitch. Who is at fault when it fails? The misuser or the Manu? I can tell a secret but keep it down low. if you ask the manu to cover this point loading issue, they can do it. Just ask! Would one jumpa climbing harness? I hope not. Would one climb a sky harness? I hope not. I am not a dealer any more for gear. But all one must do is ask for specialized gear. What is the prob? If you need, I can draw it for you. just ask. "Ask" is the theme of my post
Take care,

Re: [base283] Adrenalin Harness failure
This would be why I built a climbing harness into one of my rigs. It's a real climbing harness, designed as such, no point loading. I've seen people rap with there chest strap. Kind of made me cringe but then again the same guy was trying to tell me that I should rap on 5 mm dynema, chalk cord like for hexs. I think I'll keep humping a real rope and climbing with a real harness. And you can make fun of me for keeping a stove and bivi gear with me. But I'm not dead. All the stupid fucking shit I've done in my life and I'm not dead. You can go as fast and light as you want. You can make fun of me for walking down off of shit. But I stand by my "Not Dead" record which many people have not been able to match.

Re: [RiggerLee] Adrenalin Harness failure
5mm cord? Really? Wow.

The thing is, people can still go reasonably light by wearing a thin harness like this: http://blackdiamondequipment.com/...dQUgAdA&start=20 under their rig. Packed up it's about the size of a think pair of socks and it's a real harness, DESIGNED to belay and rappel. Chest strap rappelling is amateur hour 101.

And though I've only jumped a stove and bivy gear once, I can't argue with your track record.

Re: [stinkydragon] Adrenalin Harness failure
I use two thin black diamond 22kn slings larksheaded around the hip rings then passed behind the chest strap. the chest strap doesn't take the load but just keeps you in an upright position. any force on the chest strap is in the direction it is intended for.

Does this setup sound flawed at all?

I use quite the same thing, except that I don't have hip rings so I put the sling in the leg straps. I think it's ok.

There were a lot of things said about using the chest strap alone for abseil, most of them making sense. I can understand using your chest strap for abseil is wrong, but still, the chest strap sewing broke after only one abseil and a hard opening. Imho, it's hard to believe there was nothing wrong with the rig.

Regarding the couloir harness, did you leave the gear loops attached to the waist? I have a recurring nightmare about reaching back and grabbing the PC through a gear loop [at least partially].

If there was a lurking flaw in the harness, it will probably be apparent once inspected by a competent rigger. It would actually be really helpful and cool of you if you could post some close up, hi-def photos of the failure, for people to review. Or PM them to me if you don't want them public. Who knows what would be turned up...

Re: [Colm] Adrenalin Harness failure
I left the gear loops on; I like being able to use them if needed and they lay pretty flat and on me. They are more on the side of my pelvis and higher (near the Iliac Crest) than my PC. If they were lower and closer to the PC (which they may be on you) I would probably hot knife the right one off then fold and sew the fabric. I don't think I'd want to pick out all the bartacks. It would be time consuming and may degrade the strength of the harness.

I also used to run Spectra webbing loops lark's headed from the hip of my parachute harness (both with and without rings) to a locking carabiner with my device. I like using a Grigri2 -- even though it's heavier -- because I can carry a Tibloc with another Spectra runner and use them together to ascend back off an exit if I need to bail.

Re: [Treejumps] Adrenalin Harness failure
Agreed with everything except "there is really no reason not to make it standard." Extra materiel = extra weight and complexity of production. Extra complexity of construction = increased cost. Increased cost = sad bears for the 90 percent of customers with no need for such a feature. I think it could be a cool option for those who want.

I addition to the UL Alpine/Ski Mountaineering harness, I've also seen people rappelling on a so called Rigger's Belt (http://www.tacticaltailor.com/riggersbelt.aspx, also pretty easy to build if you have a machine and a little time). I never liked climbing or rappelling on Swami Belts (http://en.termwiki.com/EN:swami_belt; dad was oldschool), and my overall opinion of the Rigger's Belt is that it's pretty much a Swami Belt with the addition of a rad wedgie. But it works, some people like it, and it's about ten hundred buhzillion times better than the chest strap rap.

Sorry, I have nothing more that what was already posted.

I was just trying to use my common sense. What if the abseil did not damage the sewing ? What if the guy had done zero abseil with his chest strap ? This sounds possible, and in this case, that would mean there was something wrong with the rig (which was almost brand new).

Re: [MrHey] Adrenalin Harness failure
The canopy that was jumping Francois Chavelet is a Troll 305 MDV5. After the inspection by Atair, the canopy shows some damage due to an extremly strong opening.

When we choose to step off an object, the responsibility of our survival rests ENTIRELY in our own hands. You want to not die on a BASE jump for sure? Ummmmmmm...don't BASE jump maybe?
Otherwise take personal responsibility...and maybe wear a climbing harness under your gear to rap. Unsure
