- In this eye-opening work safety demonstration, we use a 150-ton hydraulic press to simulate the devastating effects of injection injuries on human tissue. Captured in stunning detail with a high-speed camera at 1000 frames per second, witness the intense pressure that can occur with hydraulic systems, painting equipment, and pressure washers. Using a ballistic gelatin block and a hydraulic cylinder filled with paint, we recreate these powerful forces and their potential for harm. Observe the damaging effects oil and paint can have on the tissue and learn about the importance of seeking immediate medical help in case of an injection injury.
Injection injuries are a serious workplace hazard caused by high-pressure equipment accidentally penetrating the skin and injecting foreign materials into the body. Consequences of injection injuries include tissue damage, infection, and even limb amputation if not treated promptly. Observe the damaging effects oil and paint can have on the tissue and learn about the importance of seeking immediate medical help in case of an injection injury.
Watch as we also explode a hydraulic hose next to the gelatin block, causing even more damage. This video is a must-see for anyone working with high-pressure equipment - a stark reminder of the importance of proper safety precautions.

Do not try this at home!! or at any where else!! - Věda a technologie
This is also one of the things where you shouldn't do a Google image search! Or if you are working somewhere where you are at risk for these then it might be good idea if you are not terrified already :D
Hi
Nothing like photos of a degloved hand
Well now I have to
Update: that was epic
I miss the videos where you don't talk
@@bitcoin00008 We have those also coming! and there is a lot of CZcams Shorts videos for you to view if you want more fast paced crushing
My old engineering teach in high school used to tell us if you suspect a hydronic leak, wave a piece of paper in front of it. If the paper is sliced in half, you found the leak. I don’t think he was being completely serious but it made a point lol
I think they were completely serious! On submarines and boats they use long sticks on live hoses and perhaps even closed lines. Never use your hands! The same goes for modern car high pressure fuel lines!
He was serious
He was serious, modern Diesel engines are the same way. Fuel pressure is so high a pinhole leak could easily slice through your clothes and into the flesh
Or grab a broom. Leave more space between you and the leak. Broom bristles work great.
I was going to comment about a boy that worked for me once till I noticed you said nearly exactly the same thing lol. The week before I had him help me he was working I think at a sod farm he said. He had a huge nasty wound on his hand and it had gain green in it and was awful. He wasn't the smartest guy but I liked him, he was a good kid. When I asked what he did he said that he saw what he thought was a little spray coming from the back of the tractor. Just like you said, he used his hand to check it. It cut him like a knife. He didn't go to the doctor and just dealt with it. But what this video didn't show or warn about is how his started as a pretty good wound but he felt he could deal with it. But, oil and the human body don't mix. What happens with flesh is it's vascular and has little pipes and plumbing of its own. When hit immediately all that ooze is injected into an area alot greater size of the initial area. The video did mention its hot tho. So he got burned and injected with the stuff. Then later his tissue started dying around. By then all the docs knew to do was to re-open the wound, scrape the dead stuff and to try and let the body push the oils back out the best it could. So yeah there's the obvious initial trauma but also hidden long term effects too. He's lucky it didn't hit a large vein or an artery. As it could have blown it up like a balloon and kill or damage with sheer pressure, or the toxic fluids that are now injected into your body. So yeah I never have that sort of stuff much thought but seeing that made me respect high pressure systems in general. Very scary stuff
Thank You for this video. Younger folks who work with pressurized systems NEED this video, not the experience. My first Navy Aviation command, we had a young guy working with a pneumatic grease gun. It was everyones first time being around a pneumatic grease gun, so no one had experience with it. They loaded it up, hooked up line pressurized air to it and ... it didn't work. They had used an old Zerk filling nozzle that had a metal burr on it. Young guy puts his thumb nail on it to flick off the burr, pressed his thumb to the end and hit the button like he did with manual grease guns and............promptly inflated his entire hand with about 2 pounds of thick grease. His hand looked like an old baseball glove, the formerly ivory white skin now leather brown and inflated to three times its normal size. It was the first time I heard the phrase 'Internal De-Gloving'. It was an instant medical emergency that no one knew how to deal with. He was taken to the Emergency Room, who transferred him to another hospital, who transferred him to another hospital and finally ....well, he got sent back to the first hospital. His hand was totally De-Gloved, but the skin was still attached. They would start surgery to clean the 'wound', by slicing every finger top and bottom from tip to wrist and scooping out heavy dense grease, flushing it with gallons of saline.... and, somewhere along the way? They called in ....a Taxidermist. I don't know why, or if it was real... The young guy came back after nearly 6 months, his new call sign was 'Frankenstein Hand'. His hand was stitches, scars, skin grafts, necrosis and he was nearly discharged. His hand was in near constant pain and... yeah, poster child for safety after that.
Jesus fucking christ can't even fathom the pain of something like that happening. Oof.
the saline isn't going to do shit to that grease either, poor guy
It was tough to even read this. Jesus..
I really wish I hadn’t read that...now I got that image of a degloved hand and other disturbing hit in my head...
I would have rather told them to just fucking amputate the hand in totality, don't bother.
I've been a forklift instructor for 18 years now (narrow-aisle, stand-up counterbalance) and I caution about this hazard every training session. There's just no way to get across in words just how nasty hydraulic fluid injection injuries can be so having a non-graphic demonstration like this is a Godsend! Thank you *SO* much for the entertaining and informative video.
Holy smokes, I've used up to 10k ATLAS forklifts in the Army, and I've never even heard about the possibility of this kind of an injury. And considering the amount of deadlined (broken) forklifts I've worked with involving leaking hydraulic fluids, I'm now realizing I'm a pretty lucky guy.
I used to be a painter working with high pressure spray equipment so this is something that I have always taken extremely seriously. I reported a damaged spray line to my superiors and they blew me off and didn’t do anything about it. One month later that same spray line busted open and spilled paint everywhere on a construction site, nobody was injured luckily but that could’ve seriously injured somebody and I was pissed that I warned them about but they didn’t listen to me. I don’t want to be anywhere near defective equipment. They are hypocrites for preaching safety but when it comes time to fork out money to replace old and damaged equipment then they don’t do it.
Paint sprayers are no joke... My grandfather was burned over a large section of his body by an industrial grade paint sprayer. I don't know how, but maybe it was gasoline powered or perhaps the paint had a bubble that dieseled on a clogged nozzle.
@@notamouse5630 The only thing I can think of is they were spraying flammable paints and coatings. Back in the day they used oil based paints that were not water soluble, they were solvent based with flammable solvents. This made it a pain in the ass to clean and get off your skin and it’s hazardous. I think gasoline powered sprayers do exist but i’m struggling to think of how he could get burned on large swaths of his body because of that but who knows. Sounds like a nasty injury. They can be dangerous, spraying flammable coatings in enclosed areas can result in fires, imagine getting an injection injury with toxic solvent based paints, that would do some serious damage. We’ve since phased them out mostly due to the environmental hazards, but they’re still used for some specific purposes like staining/lacquering and some metal coatings.
@@grimreefer213 Oh there's worse paints out there in use too. Know a guy who lost his arm mishandling a spray gun, he was using moisture cure industrial paint, the hose failed right at the joint where the hose connects to the gun. Bad part about that particular paint is the whole "moisture cure" part of it when it enters moist, human bits.
It's time to call OSHA when they blow you off
@@Puddingskin01 Oh my goodness 😱
That sounds horrendous. Yeah that’s part of the reason I left the painting industry, it is dangerous. I don’t want to risk getting maimed or injured or falling from heights, and it’s bad on your joints and body from all of the repetitive use. I did a lot of industrial painting so I worked in some pretty dangerous environments. The company I worked at did work for a company called Meridian Magnesium and they sometimes have these magnesium explosions whenever water droplets falls into their molten metal vessels. One of the painters was in a lift directly over the vat and it exploded and he was engulfed in a fireball but somehow wasn’t injured

Everybody listen to this man he is telling the truth, I did this to myself and had to go to hospital to get the body part removed, the material was expanding construction foam. I'm still alive obviously but was in hospital 8 days and had a drain for 3 months. This stuff is no joke it can be deadly. Thank you Laury for showing this safety film.
Thanks for sharing your story. I hope that this video with all the comments can prevent at least one injury like this
My God man...foam!? How!? That must have suuuuuuucked...
I'd say it was an experience that expanded in him 😜
@@HydraulicPressChannelI surely hope so too, because this is very serious. Thanks for all the work you folks at HPC do!
@@Bentree007 Well Ben I had to have a bi-lateral mastectomy, I'm trans. so yes it sucked.
I've never heard of these injuries despite working in a factory where this could have happened at several different stations. I'm kinda freaked out I was allowed near these systems with no training. 😮
hope they paid you good lol
I live in the EU. They wouldn't let me near the smallest ENERPAC toy without training.
@@TheNefastor here you arent even allowed near a machine alone if you are new, even if you were trained and are a professional
@@brynion2117 hey, at least we'll make it retirement with the exact same number of holes we were born with...
@@TheNefastor so if you get impaled before retiring, you wont make it? 😨
You wouldn't believe just how tiny and hard to spot some leaks can be. Had a leak on a lifter and the only indication was a faint rainbow if the sun was at the right angle. Literally sweep the lines with a broom to find it and watch for when the bristles start to scatter cause the invisible jet of fluid is cutting them to bits. Even with gloves on if you touched it you'd be in a world of hurt. What the gel doesn't show well is the layers and veins and other pathways it can follow once it pierces.
Couldn't they put some sort of agent into the fluid to make it stink REALLY bad? Like how certain gas has sulfur intentionally put into it so you can smell a leak.
@@Sammysapphirathats’s a good idea actually
@@Sammysapphira but it happens so often with older machins, you would stink to high heaven after a 12hr shift.
While working for a logging company, a piece of equipment developed a small pin hole in one of the hoses. it wasnt in plain view. The owner came over and was helping the mechanic look for the leak and ran his hand over it. It filled his ring finger with hydrolic fluid and within 5 seconds he had a pocket knife out and cut his own finger off. Said it was the worst pain he had ever felt in his life and the knife was a relief.
Hydraulic fluid is extremely toxic when inside the body. If he didn't cut it off without getting fast medical treatment, he would have been dead.
Right at the knuckle. Scarred me for years
@@l3igcountry that's actually pretty badass
Depending on how far away the nearest hospital was the doctor might of approved.
This is the kinda guy that would survive a zombie bite by immediately lopping off his own arm before the infection spreads.
Years ago I worked for a hydroblasting company using up to 40k psi equipment. We all had to carry a special card with us in case of injury that told doctors how to properly address an injury since it was such a specific kind of injury.
That’s nearly 2758 bars for those who want the conversion.
This amount of pressure will go right through two people if the injection injury is located at the chest. Bones included.
So if you could effectively get mercury to those kind (or perhaps even a theoretical liquid with an even higher density via simulation) pressures how many human bodies could it be able to penetrate through?
@@thedoctor2102 I'm admittedly not smart enough to have an answer for that question, but I can tell you that I've seen the water shred through reinforced concrete like it was Styrofoam, in case that gives you a good idea of the power.

I’m a heavy duty hydraulic service technician. This is the first time I have seen a demonstration of HPI. “Hydraulic pressure injection”
I thank you for this. 🙏🏼
As a professional painter this type of injury is one of the most dangerous and common we need to be aware of. Our pumps usually operate between 1800 and 3200 psi. Being exposed to a pin hole in a hose for even a tiny fraction of a second can result in extreme injury or even death. It's not just the Injection you need to be aware of, the material injected (paint in our case) even if it is low VoC is super infectious and can kill you from infection weeks or months later.
You should just use paint brushes. Those r low power
i held my muddy license plate and tried hitting it with a pressure washer, the pressure forced the wand up and hit my hand. that really really hurt! my hand was beat red. was only literally just a second, half a second even.
To reemphasize points I've heard: anything above 100 PSI may cause injection injuries. Some injuries are not even apparent from the surface, presumably given a small enough pinhole leak; you just feel a sting, and that's it. A large part of the problem isn't the physical damage, its the horrible infections or poisoning that happen a few days later.
Experiencing the severity of the cavitation demonstrated in this video is going to hurt more like a gunshot than a sting, but it wont *appear* to be so damaging, hence manly-men dont get it checked out and wake up dead
The cavitation is also extremely destructive to tissue.
@@dezmodium
Yep. That’s why hollow-point bullets are hollow: it expands rapidly as it penetrates, dumping a monumental amount of energy directly into your body faster than one could blink.
Still can’t get over just how severe these kinds of injuries are. And I am still shocked that hydraulics can have the same instantly destructive effect (with additional complications).
100 psi is around 6 bar for euro folks
En qué situación eso puede ocurrir?
Closest to this I have experienced was taking a sweeping hit from a pressure washer from about a meter away. Went across the inside of my arm. The immediate thing was severe pain over the whole area, then a frightening amount of blood. Hosed the blood off and I saw I had hundreds of tiny holes in me. Went to the Emergency Room to get checked out. Because it was just water no worry about chemical burns or poison. Doc numbed me up and opened me up a little bit to see how deep the holes went. Just 1-2 mm. Said I'd be OK, just don't scratch the scabs off. (This was very hard to obey) Gave me a tetanus shot in the ER and a script for antibiotics to keep any infections away. Took maybe 2 to 3 weeks to heal up.
Yea, pressure washers and airless paint sprayers are famous for this kind of injury.
You got extremely lucky. They didn't have to peel back your flesh to clean the wounds from the inside like what happens with more serious injection injuries.
I worked for Timberjack, a guy I worked with had his finger pierced by a airless paint sprayer, it shot undercoating into his hand, he lost half his hand, he said he passed out from the pain.
@@oxyfee6486 Yea, paint sprayers can do severe damage.
Jesus dude...
Having been a forklift operator for 20 years, I’ve seen plenty of hydraulic hoses burst. The worst one happened just after shift change. The operator before me had failed to mention my lift should be out of service. Thank goodness it burst in my pre inspection and not under load. I still got covered in hydraulic fluid as one of the pulleys had broken and pierced the hose when mast was raised. I was completely drenched in hydraulic fluid and there was a huge mess to clean up. First instinct is protecting your face and close eyes and not breathe until the shower stops. Call for help on the radio and wait for floor dry to be spread so can get off the forklift.
Did it burn your eyes
@@jordan_.zx10r no. I was wearing safety glasses and had a hat on.
@@Its_just_Dave. I wonder if hydraulic oil burns your eyes. I swear I splashed some into my eye tiny amount from taking a seal off cylinder but didn’t hurt at all
I was a US Naval Aircrewman on the P-3 Orion. After taking off one of us went thru the aircraft making sure all is good. One of the areas was the hydraulic service center. If we looked in and saw what looked like smoke we had to assume it was hydraulic fluid leaking at high pressure. We were to take the broom and wave the handle around to find where it is leaking. *NEVER* put your arm in there since it could cut off or destroy your arm.
I talked to a Navy guy who served on "a small ship" (wouldn't say what kind) and saw two sailors drag some idiot junior officer trying to find a leak with his hands when they were "taking too long" to find something else. Long story short it went to Captains mast and the captain threatened to have the officer find leaks with his face.
Now, remember that hydro-cutters often have AT LEAST 10 times more pressure than what we have here. Then, the jet is normally narrower. In some cases, you can't even SEE the puncture.
VERY sound advice. Even if you are not sure, just go to the ER if you suspect that you may have such an injury.
Not only that, but something as innoucous as a diesel-injector can get way worse than that. This video is giving me PTSD.
Pin hole leaks in steam pipes..
@@geneticepistomology Ugh. I was in the navy and this was something we learned about, in-depth. Nasty.
If you didn't come from Tiktok raise your hands ✋😊.
Whats tiktok?

Raising hand
This reminds me of someone who wanted to become a car mechanic being taught about the dangers of diesel-injectors. Whenever someone was handling the dummy-injectors outside an engine careless (handling them with their fingers on the outlet, for instance) the teacher would give them a reprimand for that, telling them that if you would do that and for whatever reason it would spray diesel at that very moment, you'd be without that finger or at least suffer a massive injury to it. The teacher took the dangers of those parts superseriously.
I was working as a temp at a car wash, spraying pressured water. My finger barely came into contact with the water stream and I got a tiny injury that hurt a lot and took days to heal. I realized how serious it could have been if I had taken more of a direct hit. It was a lucky lesson.
Excellent job simulating skin here too! It's a common mistake people make to just use straight ballistics gel. Skin is shockingly puncture resistant and elastic, far more than gel, I think the FBI said before that skin is equivalent to a few inches of ballistic gel typically, don't quote me on that. Leather is great for this because it's tougher than skin; if it punched through leather, it will DEFINITELY punch through your skin!
The FBI standard you're thinking of requires 12 inches minimum acceptable penetration of properly calibrated gelatin, as the equivalent of sufficient penetration in flesh to reach major arteries and organs. Just penetrating the skin is not necessarily sufficient to cause incapacitation in the law enforcement context they studied. I agree this would be a life-changing injury though. You can read the article here: www.ojp.gov/pdffiles1/Digitization/122334NCJRS.pdf
I think pig skin would be a good medium as well.
Leather IS skin, just not human skin.
@@CanizaMno, Leather is treated (tanned) skin. It has been chemically processed altering it's properties.
Leather can be made with all animal skin, even humans. Cow skin is just the most common.
But you can't compare it to living skin anymore because it changed properties in the process.
Ballistic gel is mainly used because it is repeatable and consistent, not because it is so close in properties to flesh. (It is close enough obviously to have at least some kind of validity though).
I worked security at a place that manufactured hydraulic pumps. They had a torture room where they tested stuff way beyond the rated maximum. Some of their bigger pumps would run 30,0000 to 60,000 PSI. They showed me a video of a pin hole failure at 30,000 PSI and it cut the gelatin dummy in half, and it had simulate bone and organs similar to the ones from Ballistic Dummies (though this was way before that company existed as far as I know).
I repair hydraulic cranes for a living, I see and touch hydraulic hoses every day. This video has given me a new perspective on them. I've always heard horror stories regarding hoses exploding so I've always been careful around them regardless of this video, thankfully, I've never witnessed any major accident regarding them, but to see the damage it can cause to this excruciating detail is amazing.
Guys, I just wanted to say that I'm so proud of both of you. I've been subbed to this channel since the beginning. I remember when you only had 10k subs. Look how far you both have come. You're almost at 5 million subs, and you're gonna hit it. Thank you both for all you do, and thank you for bringing joy, laughter, wonder and intrigue to the world through your videos.
Congratulations on hitting the future 5 million mark guys!! You both deserve many more subs!! 💜🤝
If high school training videos were made like this there would be far fewer accidents.
@@asbestosfibers1325 fr, i accidentally went down a rabbit hole n it was so bad idk why i kept watching
Somehow, I'd think these "indestructible" kis would try this at home! Unfortnately.
Yep. When I was a kid, public safety videos used to be more shocking. There were a couple I still remember about not messing around on farms, and not trying to get your ball back from an electricial substation. Then I think they got stopped because they might scare the kids.. Which was the point.
Then as a bigger kid, I had to watch a bunch of safety videos before being allowed to go on an inspection trip of some utilidors under NYC. That included high pressure hazards like steam and other gas and fluid lines. There were some pretty gruesome videos of injuries like this, including removing an 'urban explorer' in kit form after they found a leak.
Ever since then, I've been very very careful around hydraulic and high pressure systems and never test them with anything I want to remain attached to. It depresses me when I watch YT videos of people using fingers to check for leaks, or doing pranks with consumer or pro-sumer pressure tools that have the potential to cause serious injury. Like he says, it may not seem bad initially, but then a few hours or days later, the infection, inflammation or toxic reactions from whatever got blasted into deep tissue appear.
The unfortunate part is much of everything now is electronically controlled or engaged and the youth have no fear of hitting buttons on a keyboard. There is no physical contact with risk or fear. Even in my training days late eighties / early nineties much of anything of consequence still needed physical with an element of fear to do something that sometimes seemed like the stupidest thing to ever do unless your mentor or boss told you to.
@@asbestosfibers1325my shop teacher was far too drunk every morning to worry too much about us students. We got some videos and whatnot, but we had several serious accidents and we also played "the hot metal game" where you take a peice of really cold, or hot metal, touch someone with it and they have to find out if its hot or cold
I’ve seen injection injuries. Not only are they catastrophic but the healing process takes forever. They’re horrible.
I haven't luckily ever seen one but heard that they are terrifying in every sense. Lets hope that this gets millions of views and we can safe at least one person from getting one with all the fear that this is going to pump into the people
@@HydraulicPressChannel i 100% agree they are terrifying
Agreed. And the injection under pressure isn’t the only problem. The oil itself is toxic. Look up “degloving” if you want to see the results (and you have a strong stomach)
@@HydraulicPressChannel pump fear into the people, that's a funny way to say it )
I had a fairly low pressure oil injection/burn on my forearm. Luckily it burned/cut off most of the surface layers of skin and fat and didn't hurt most of the muscles so I didn't get a huge oil bubble in me. They opened it up, removed the ragged stuff and oil. Then they packed it with gauze, changed it every 6 hours, IV antibiotics twice a day for a week. After they sent me home it was oral antibiotics and packing with gauze for about 2 months. No stiches just a huge hole in my arm that eventually grew from the bottom up. I have a scar an inch wide and 3 inches long and some nerve damage in my left hand. 2/10 would not recommend
2:15 Damn I kinda wish I was a block of ballistic gel now for some reason
u good?
I friend of my father used to tell us about his days as an engineer on the first nuclear submarine. A similar thing happened to a crewman near a bulkhead except it had high pressure and temperature! They had to use UV dye to find a leak the size of a pinhole!
This is why you NEVER feel for leaks with you're hand when working on hydraulic systems.
You can actually feel for leaks twice with your hands. That's because people have two hands, so when you lose one, you still have the other one to feel for leaks. /s
@@LordDragox412 Do not look into laser beam with remaining eye.
Correct . Always use your tongue 🤪
Use a piece of paper
You check for leaks with your hands just like you'd check a mains cable for nicks or cuts: With the system proven dead, i.e. confirming that there is no pressure on the circuit you're inspecting.
Had a friend in the 70's that accidentally touched a leak in a hydraulic line. His finger blew up just like a balloon! They literally sliced the entire length of his finger in two, like filleting a fish, then had to squeeze the fluid out of it. He had to have that done several times over a period of months. Also saw a couple painters lose their fingers from airless paint sprayers... This no joke!!!
I'm very happy that you brought this very dangerous fact of high or super high pressure dangers. Any thing injected at high pressure is a huge potential for major damage. PLEASE BE CAREFULL.
I watched a shipmate who had his arm sliced open by a high pressure pin hole leak. The stream was very fine and basically invisible in the light available.
I was taught to use a piece of cardboard ahead of my hand or arm before reaching in. Just a finger tip blast can lead to a loss of the finger.
I seldom get startled by stuff like this.
But I severely underestimated the damage that hydraulics can cause during a rupture event… *this is hollow-point cavitation levels of damage with the added complication of toxicity and internal burns!*
When i was a child growing up in the mountains of West Virginia we had to clear off a hill side cutting down trees for firewood for my family and our neighbors. As well as opening the road way. My neighbors brought their tractor to help. The tractor sprung a leak and my neighbor was trying to find the right hose to change he grabbed 2 hoses and told his wife to work the function in a split second his forearm filled up with hydraulic fluid like a water balloon 2-3 times the size of his normal forearm. They went to the hospital and they cut him from the palm of his hand to his elbow and removed the majority of his arm meat. He had several scars and a big chunk of his forearm missing. He could not work after that and became an evil alcoholic that drank from the time his eyes opened until he passed out. His wife eventually grew tired of his abuse and lifestyle and left. He drank himself to death. It was sad to see because he was a good man before the accident. Worked every day and took care of his family. The neighborhood tried to help him as people from WV often did back then but he refused. He died a lonely hateful old man 13 years after the accident. Be careful around hydraulics they could change your life.
If that's who he turned into after a serious accident I sincerely doubt he was a good man beforehand either.
@@Abbanellie people have a breaking point. Pretty harsh judgement you have there. I guess people are just born even and always evil right? No one turns evil
@@Dogpool I think his judgment was sound. If you turn evil, you were always evil. Genuinely good people have the capacity to maintain their good nature through events like this. Good people don't abuse people just because they've had a bad experience in life.
I worked for a company that made ultra high pressure pumps, for water cutting and heavy cleaning. The pumps went from 20.000 to 55.000 psi. The pictures and videos of accidents everyone there saw during safety training were horrible, and once during a company barbecue they both ribs and cut it with a 40.000 psi pump with a less than 1mm sapphire nozzle "gun". Cuts bone like it's hot butter.
How does hot butter cut bone?
@@Peststurmtief With enough pressure behind it, I'm sure it'd be a perfectly adequate cutting fluid. DO NOT try this for injecting your turkey next Thanksgiving. Or perhaps that's another video idea, because it'd show some of the effects of degloving.
Pump don't really create pressure they create flow. Resistance to that flow creates pressure. Now yes the pumps have to be able to resist back flow
@@Peststurmtief You're not a native English speaker are you? 🤣
@@krashd no need to be a native speaker, that sentence can indeed be read both ways and so the joke is valid.
This video will have saved many limbs and at least one life to judge by the number of views. Well done!
This is something every kid that gets a job at a car wash should have to watch. So many injuries happen in those places.
My father told a story of an aircraft mechanic who noticed hydraulic fluid on the padding along the rear side of the aircraft. The mechanic ran his hand along the suspect metal hydraulic line without thinking and lost most of his fingers in just a second. The line had a pin-hold leak and the pressure was many thousands of pounds per inch. Basically became like a hot wire and hurt his hand badly.
Jesus, thanks for the heads up, I never gave it any thought how high pressures can do this.
I worked in Hand Surgery/Rehab early in my career. A painter accidently injected paint into his finger from a paint sprayer (hyrdraulic injection) while cleaning it...result?
Full finger amputation and extensive rehab
That’s why i’m no longer a painter, it is more dangerous than people may think initially, it’s also physically taxing
This can also happen with airless paint sprayers (they use a corkscrew pump to get the paint up to about 3000 psi before it exits the nozzle). Ive heard stories of painters who accidentally or ignorantly wave thier hand in front of the sprayer and the paint sprays instantly into their flesh. The injury doesnt stop with the mechanical damage either because paint in your blood stream can be extremly dangerous so when this happens the victim usually needs to get extensive surgery well beyond the insertion point.
The worst thing is not the injury, but the fluid. My father almost lost a finger to a hydraulic hose leak. The injury healed, but since then, his kidneys went downhill and was for years in dialysis. Last year, he finally underwent kidney transplant. He is much better now, but damn, hydraulic fluid is poison to the kidneys.
A friend's father suffered a work injury like this in the 70's. The external damage was just a tiny hole but the internal damage to his finger was massive and he ended up losing the finger.
I guess he just gave the doctors the finger.
Ixm incredibly thankful to you for sheading some light on this topic. I am not a operator or maintainer of hydrologic systems, but I am occasionally around them for work and had no idea of this danger.
Thank you for showing these types of injuries. I work with forklifts everyday and sometimes worry about hydraulic injuries
My dad actually had this happen to him during a lapse in judgement. A hydraulic hose blew on a skid steer and he grabbed it. It wasn't pretty but he did make a full recovery with minimal long term effects. The hole in the hand was the least of the problems, the hydraulic fluid was a different story.
isnt hydraulic fluid toxic?
@@The4stro yes
They removed a fair amount of damaged and oil soaked tissue from his hand and he got right to the ER which helped. Also, I believe he was pretty quick on the release so that the damage was less than it might have been. It's amazing how fast we can react during those WTF was I thinking moments. Regardless, he was extremely lucky and IMO came away better off than he probably should have.
@@jeffreywhitmoyer860 grabbing the broken line is exactly what i did too; the pain sure helped in letting go quickly 😅
I used to work in hydraulics and I knew a guy who had this happen to him. On top of the damage you have to deal with the side effects of hydraulic oil in your body. Ever since I moved on from that job I've had a fear of hydraulic systems.
I just came back to check the sub count and I see that 5 million has been achieved. Congratulations! You guys definitely deserve this!

Me with someone’s daughter: 2:39
I can’t stop laughing!
As a former paramedic, I can tell you, I've seen a lot of horrible shit. Always be careful folks.
I feel like the gravity of these injuries just got served a boatload of respect by you creating this content. Good job with the contrasting blue, etc.
This may possibly be one of the most valid videos on YT.
I haven’t watch this channel for years and I’m so happy to hear Rally-English in my ears again
Mr. Gel took that like a champ!
Ballistic Square Bob No Pants thinking: "This video was such a pain in the ass to make."
Or at the back end of bob as I try to keep saying and sounding professional :D
In this case, I don't think if he were wearing any pants it would have made a difference.
I've always heard about these types of injuries and wondered how exactly it ends up happening. After literal years, you have been the first to give a nice visual and verbal explanation. Thank you, love this video! Be safe, everyone.
For medical people that ended up here somehow: the treatment for this is tetanus prophylaxis, irrigation, and gross surgical exploration with gross decontamination or sharp debridement of contaminated and devitalized tissue with delayed or secondary intention/closure. Much of the time amputation is indicated.
For EMS: do NOT apply ice, irrigate the injury, consider pain management as needed/indicated and transport to a surgical center. Do: initiate a poison control case and find out what specific material was injected through the lines. Treat it like a trauma with hazardous material exposure/ingestion.
This needs to be used as a workplace safety video.
I think the one thing that is more terrifying than injection injuries is high pressure steam injuries. I think it would be interesting and informative to also try to demonstrate those, as long as you can do it safely.
name 😂
If there is something worse than hydraulic injection injuries, then high pressure super heated steam is a good candidate. A super heated steam leak is invisible but extremely loud. If someone panics and runs through the steam, they can lose limbs, be cut in two, or blown off their feet.
Moderate pressure HF leak?
I was a boiler technician in the USN. We ran 1200 pound, 1200 degree steam in a 16" line, as well as all the other smaller lines and pressures. The boiler room was so loud, you would never hear it. The only indication of a leak in the main line would be pressure differences on the gauges. In that event, the procedure for detecting the leak would be to look for any condensation on the ceiling or walls, it could actually cause it to rain in the boiler room. You could not see, or hear it any other way but even then, you still would not know where it was coming from. So, the procedure was, to take a straw broom and run it over the line and wait for it to cut the bristles off. This steam could cut your head off, and cauterize the veins, so you wouldn't even bleed... Fun times...
My dad was in the Navy. He said that if you were in a space with a superheated stem leak, you waved a broom stick in front of you before you moved. When the end of the broom stick fell off, you found the leak!
injection injuries are so so dangerous , thanks for the video , brilliant video .
This should become a standardized safety video. Thank you for making this.
Good thing to spread awareness of. Not a common injury but potentially lethal, prompted me to research it realized how right you are and it’s bound that someone somewhere along the line will have this injury while working on machines. Hydraulics are just so useful!
I've been fixing hydraulic lines on the excavator at work and I'm going to be extra careful now!
You should try the candles against the ballistic gelatine
Yep be careful and use your head. I've had a hose on a crane truck outrigger I was working on blow without any warning before. A line of fluid the diameter of a needle, like a freakin lazer beam shot right over my shoulder next to my ear. It could have been SO bad.
Another thing to remember is that as soon as the system loses pressure, anything that was being held up by that fluid will fall. Always take a second to look around and think before you remove a hydraulic line, as the machine can "settle" right down on top of you.
@@Bloodbain88 bloody lucky! I've heard it's really bad to get hydraulic fluid in wounds too.
Yeah I've learnt to extend the boom now to relieve any pressure but it just takes one screw up to be the last screw up.
This needs to be included in every safety video catalog for all vocational occupations.
When I was in the industry, I ran a water jet for 2 years.
The training videos were terrifying, those things can do damage. This highlights how scary those are.
Thanks for keeping the fresh content coming!
One of the very first things I was taught when learning to drove a forklift, pictures included, and I'm glad they really emphasised how dangerous it was because it stuck with me
On the pipe burst test -- I've never seen ballistic gel deform that much without penetration. I'd love to see the test run again but with the ballistic gel held in place.
It would have also been good to have a pressure meter on the end of the hose so we'd know just how much pressure there was before the pipe burst.
At these kinds of speeds there's essentially no difference between holding it in place or not, the inertia of the block itself is already plenty enough. Same if it's getting shot by a bullet.
@@Me0fCourse Considering that the block of gel jumped, basically, its entire height off the table tells me there is a decent probability that there would be a difference.
Eh? The paint went almost through the block on that test though you cant really see it until the highspeed shot
Yeah, putting a decent sized weight on top of the block I suspect would lead to some interesting results. If it couldn't deform up it would most likely end up getting squeezed out the sides which would probably then increase the odds of the paint penetrating the block (if not just splitting it in half). Realistically the biggest damage in a quasi-explosion like that isn't even something you can see with ballistic gel which is the blunt trauma from the impact. Even though it didn't technically "penetrate" if that had been an actual person you'd have severe internal organ damage.
@@fred_derf a person, when hit by something at pressure or speed will move and deform. I have been unlucky enough to be first responder to some nasty shit including a high pressure hydraulic line split. It hit the guy in the chest but what saved him worse damage was it also knocking him backwards so it lanced clothes and skin but didnt go as deep as it could have if he was rooted in front of it.
We are fragile things, not solid blocks.

Someone's Daughter: 2:16
thank you both, hope you are well!
The injured tissue area would actually be quite a bit larger than the maximum size the bubble achieved, because the surrounding tissue would be subjected to crushing pressures that would rupture cells and tear apart tissues such as muscles, veins and arteries. That kind of damage can take an extremely long time to heal because of the extent of damage and the interference with blood flow to provide materials to rebuild cells and tissues.
2:29
someone stop me from making a joke from this
Thank you for this video. It is an excellent reminder that safety is so important around hydraulics.
One of best hi speed shots on CZcams ❤
What are your intentions with our daughter?
Me: 2:16
Now imagine what a high pressure steam leak would do. I hear that in the navy, they look for those with a broom. If the end suddenly falls off, you found your leak.
Imagine walking along somewhere in a ship and the suddenly the guy in front of you gets „Resident Evil’ed“. There would not even be time for „Oh shi….“
OMG it's been so long since I've watched a video here. I have a lot to catch up on. Good to see this channel so close to 5 million subscribers. I can’t wait to see what they do for a 5 million special (should they decide to do one)
You guys must have had a lot of comments worrying about this on your last video with that candle...I was. I'm glad to see you both are aware of the danger.
I didnt know about this kind of injury and now I'm terrified thank you!
Yeah, hydrolic pressure is scary. I'm an auto mechanic and my previous job was at a hardware store, we had a '90s forklift with VERY old and worn hoses, one day I noticed they were soaked in hydrolic fluid, and INSTANTLY told my boss and didn't get neat the forklift until they installed new hoses.
finaly somone making a video and demonstrating this thank you so muche hpc !!
We used to have a guy at work who worked on steam boilers on military ships in WWII, and he talked about how they'd find leaks in high pressure steam lines by waving a mop or broom along the lines, and the leak would chop off the bristles and blow them away.
You guys should definitely make more of these videos featuring this tool. Very satisfying.
The product value of your work place safety videos are top notch!
Ngl, the ballistic gel block man (with the googly eyes and the Freddy Mercury moustache) looked like he kind of emjoyed it.
These are my favorite ones. I was sitting there waiting for that line to burst, but it still made me jump a little. LOL
I was waiting for this! it’s so important for the inexperienced ppl working on hydraulic sistems that a pinhole in a pressurized pipe can be fatal!
100psi air hose can do serious damage also. My brother had a co-worker disconnect a quick connect air hose and his whole forearm blew up like a balloon. Dr thought he may have had an existing injury which allowed air pressure to enter. Brother said his arm was messed up for a long time.
Reminds me of the old stories about being in a submarine and then checking for leaks with a broom handle and seeing if it cuts it in half.😊
This explains anatomy a lot.
and the worst thing about such injuries is how human flesh is layered and it fills the gaps and ends up in bloodstream and often either ends in amputation or death.
yep the gel is way more uniform and simple
Nice !
When I attend my school for machinists,they showed some pistures from catastrophic failures of hydraulics,including missing fingers,hands,whole arms etc..
I can say for myself,I've got much more respect for hydraulics systems...and their maintenance...😅
I love the accent, it never gets old.
“Welcome to the huuudraulic press channel!”
I love your videos and speaking english, it's always makes my day better.
Keep on with your projects, it's really fun and actually educational.
Well done again.
Greetings from Norway.
Its funny, because as scary as this portion of the injection injuries is (makes you go "wow that doesnt look good, definitely dont want that happening"), the "what happens after" is even more horrifying ("wow... is that worse then death? Maybe.").
I wasn't expecting to see a gelatin block getting creampied today💀
with paint of all things
smurf coom
When I was younger I actually waved my hand through a pressure washer we used to use at work for the kitchen floors (not sure on PSI, one of the ones with the onboard compressors, listed as 2000psi max), didn't actually go through my skin at all, but the force was enough to bruise my fingers pretty badly.
This happened to a Scottish firefighter about 6 years ago.
There was a pin hole in the hydraulic hose of the equipment he's was using, and it shot hydraulic fluid into his hand. He lost his hand and got a million pound pay out in compensation
Thank you for the entertaining content. I look forward to these every weekend. It's a great way to start my day.
Pidän todella videoistasi ja siitä, kuinka kuuntelet katsojiasi! Ystävällisin terveisin, James
2:16 that scream and him saying, "I got too excited and he was too fast" 😂
It's amazing that this is coming out a day after the Slo-mo guys used a very similar gel cube, only with an Epipen. The difference is staggering, to say the least.
I was really amused also about that :D I even thought earlier this week should I release something else since I have had so much hydraulic cylinder stuff lately
