This is done often but is very dangerous.

is this spot the mistakes? have counted 7 before they even turned the air on....

Ok watching that scared me and I wasn't there. It would be very suprising if no one got hurt with the way they were doing that

not a very good demo on how to, maybe this is some of mistakes commonly made that can cause serious injury or death should be the title.

Yes, it is a "spot the mistakes" video ;~)

how many in total then???

The clamp wasn't even closed!

ok wtf was that blowout cap lol , is that normal ?? what about doing the clip up and putting saftey pins in it ... or maybe they couldnt do it up because the rubber is looks like something i used to do burn outs on when i was 18.

Is that a normal blowout cap used in the states , we have pressure relese valves and pressure guages on the cap you can just about make the sponge fall out the other end with a bit of practise!

No thats not a normal blow out cap. It looked more like a garden hose. And the cap not like any I have seen at least not on any pump I have ever run

Let me guess,an upcoming episode of dirty jobs right?

Beyond that well I'll keep my mouth shut.

Is this from mythbusters? They normally explode everything at the very end of their myth hunting.

WOW!!!!

what a bunch of WANKERS!!!!! What safety???

i know this is kinda bad to say but we had one guy who was my helper a freaking idiot i had to show him everyday how to put a clamp on kinda idiot on his last day i put a big sponge in the hose and turned the pressure up and watched as the hose picked him up 6 feet. i know its not safe but hell if it wasnt funny as hell. lol

Are you kidding me.Todd where did you get that sh--.If they keep doing that someone will get killed.

does your reqular air system on your truck have  the volume to do that,or is that a 185/250 cfm type comp.?

It does work, but is a bit slow, depending on line size and length. Its more of an emergency thing to use this, the compressor on the truck is not built for continual use. If u fit an outlet to your system then you must use valves to ensure you dont loose all the air, this can lead to loss of pto on certain machines and brakes on some japanese trucks, when the air builds up again it can damage the pto by trying to reselect.  Can save you a boom set though!!!!

Bear you get scared when you walk out your front door lol
