What Would Happen If You Swiped The Waterjet?

I've accidentally run 12 thousand psi across my steel toe cap boots, luckily it went over the steel toe, it was a quick pass and cut my boot open from side to side through to the steel. A lesson NEVER forgot and i still cringe years later at how bad that could have been. (edited for the stupid on 12k psi or 12.000)

A guy where I work once tried to clean a rotary airlock out while it was running. He said he felt a slight pinch, pulled his hand out and was missing 3 fingers. Needless to say, he was the reason for the airlock safety procedure video.

I'm naturally inclined to make peace with my enemies, but I could never shake hands with a hydraulic jet.

I have actually had a water jet injury, back in 2008 or so. The beam started over top of my hand, while cutting 2.5" thick field stone, and turned the inner part of my thumb into mist. Lots of blood, lots of pain. Luckily, I didn't lose my thumb, but it was close. Took a long time to heal, and it has not been the same since. Permanent nerve damage, and some loss of mobility in my thumb. Let this be a PSA to anyone who uses a water jet

as a physician id like to add, waterjet injuries even pressure washer are a very serious emergency and treated the same as high velocity firearm injuries. they cause extensive tissue damage even if the outside doesnt look very big, due to the high pressure diverting force laterally as it encounters resistance and continues to damage tissue as it separates flesh from bone. thank you for making a high quality interesting video

I've never been so grossed out by ballistics gel body parts getting wrecked but that first hand was hard to watch 😂

A guy I worked with had a high pressure sprayer loaded with tri-chlor to clean it out. He squeezed the trigger and couldn’t see anything, so he ran one finger in front of the nozzle to check. It was spraying a stream so fine and hard that it pierced his finger to the bone and filled his hand internally with tri-Chlor. It was a horrific mess and there were surgical amputations.

The fact that the water was able to grip anything is absolutely terrifying

Thank you for curing my primal urge to swipe my hand through a water jet

This takes me back to when we first learned woodworking in middle school. Our teacher was extremely strict about the safety rules and to demonstrate how important it was for us to follow them he took a thick stick and showed how the bandsaw was able to cut through it like a hot knife through butter. Of course we weren’t allowed to use it but it definitely made us take all of the other rules seriously. Especially since he would also threaten to show real life pictures of injuries that happened as a result of people being careless. Needless to say he was a very good teacher.

A video that shows the main point instantly? Then repeats the main point with 50 equally interesting variations?.. my man.. you are a legend! Thank you for the content!

This is critical information I definitely need... I've never even seen a waterjet, but now I know what to expect if I meet a waterjet in the wild

Not sure how you could test this, but something I was taught when learning to use a water jet is that getting your hand/fingers cut off is the least of your worries if the jet hit you. I was told the pressure was so strong that it would backflow through your arteries and push garnet into your heart.

This video is compositionally perfect - doesn’t drag its feet with a lot of stupid build-up, gets right to the action without melodrama… because the results are dramatic enough. Nicely done. 🤙🏼

Worked with a flow water jet for almost 14 years now, never gets old seeing the power of water and sand at work cutting through anything in it's path! Never forget rule number one, the machine will win the fight every time.

Work in a shop a lot, thought I had a pretty healthy respect for the danger but it turns out that after watching this video it can actually get a heck of a lot healthier.

I came into this video expecting the first 75% to be filler footage and the last 25% finally showing the experiment, but I was pleasantly surprised to see y'all got into the meat of it all super quick. You've earned my like and subscribe for doing it up right and I look forward to seeing more from this channel. 👏👏👏

The scary part about the water jet is the pressure in an actual hand would cause water to flow up and down the sides of the bone, through vessels and so forth. So your getting a lot more of your hand, or more, injured than just where it’s hitting.

When I was a kid I was pressure washing some stuff for my grandparents and got a lot of mud on my legs. I held the nozzle about 2 feet away from the mud to spray it, but I tripped and wound up blowing about 8 inches of skin off my leg. Great experience!

Having watched this and also having a water jet accident myself. This is definitely accurate. Blessed to still have my hand and finger.
