Got a powderman ticket years ago in NSW at TAFE . One day on the course we were being shown how to dipose of old / out of date explosives. The instructor was a marble quary guy & liked black powder. We were told to chek the sticks for dets & lay them out on straw bales & douse in deisel. So this bloke lays a trail of black powder to the straw while talking & does not notice the powder had built up quite a pile & lit it up ! It went bang in his face & he lost most of his eyebrows & beard & just said "thats how it's done & I've got to go & shot off to the first aid room. Showed me just how carefull you need to be & show attention to details. Everyone thought it was halerious !! But???
When a was young a Sergeant in the Canadian Army told us Cadets of an NCO that held a blasting cap and blew his fingers off. :( That blast was very cool. Thank you for sharing.
I really like you're channel, and respect how controlled you are. Keep the videos up man because they are great ! I work for a blasting company in Canada and have always wanted to work in Australia.
HI Chum, Thanks, What sort of blasting works do you do? The climate is a bit more outside work friendly here - I've only worked in the snow once, bet you do it half of the time.
Demolition Dave Drilling and Blasting Yeah mainly quarry's, pit's, and mines. We rarely use ANFO, pretty much all emulsion and yes. We work all winter and it is cold haha. A previous company i worked for we did alot of construction blasting like you do. Anything from highway jobs to subdivisions and dams. I have always wanted to blast in Australia though.
I've done this, with rolls of B-line... powerful stuff... Dave is absolutely right! don't mess around with this stuff, if ever found please contact a professional like us to dispose of safely
This is a true story, many years ago a Locksmith in British Columbia, Canada, decided to torch a hole in an Large, old JJ Taylor Safe. Inside unbeknownst to anybody were stored Lord knows how many old Detonators, exactly like in this video. The intense heat and flame of the cutting torch set off one or more of the detonators, and a rapid chain reaction set the rest of them milliseconds later,... The force of the blast ripped the door entirely off the safe, and hit the Locksmith in the chest, throwing him to the other side of the room, killing him.
That does not surprise me at all Mike. A friend of a friend has an old safe that he keeps just to show people, it came from his business premises, on night guys broke in and torched a hole in it... but it was not even locked at the time.
My uncle used to use the plain detonators back in the 70s in coober pedy and up thru the mid 80s locally. He got all the licenses and stuff. When he died we found a bunch of fuse in his stuff and threw it in the fire. Most of it burned and some but not much went like a sparkler. He used to tell me that detonators could blow your foot off.
Yes, certainly could make a mess of your foot, you don't want to throw dets in a fire! If you ever have this situation again it's a good ides to get expert advice.
Yeah it was quite a crack! The things that really surprised me was how shredded the tyre was and how bright the fireball was, probably all of the aluminium in the dets being consumed added to the brightness. you might enjoy these one s also - th-cam.com/video/UpNq9R5qWWI/w-d-xo.html th-cam.com/video/ga1aAjYB_Ng/w-d-xo.html th-cam.com/video/HbPs0VUq7eE/w-d-xo.html
Is there anything you can do to improve your fire cracker recipe, besides 70% potassium perchlorate and 30% aluminum , I'm only trying to achieve the loudest firecrackers, I now it's not your niche. The PETN sounded like a higher velocity bang, than the pyrotechnics stuff I'm working with
Great videos. Couldn't you dispose of these detonators a few at a time on a job site? Just throw them in the hole with the real explosives. This does look like fun though. Also, what animals ran away in the background of the video?
Can't believe how it shredded that tyre anyone thats ever tried to cut a old tyre knows just how resilient they are. How much of the bang though was detonators and how much the red cord stuff?
You dead right Adam, even I was a bit surprised, the biggest part of the tyre that we found was a 20cm long and the entire area was littered with tiny pieces. The steel belting was shredded. The explosive in the det cord and the base charge of the detonators is PETN - this is top shelf stuff. The red det cord contains 10g/M and there was about 12M total (120G) and 240 detonators were attached, they were a mix of No6 and No8 strength, the average per det might have been ~ 0.4g, so det contribution = 96g, so total PETN load = 220 grams... A lot of damage, the super heated atomised petrol (~3L) may well have contributed also. I have also done a lot of work with old tyres when making blast mats so I understand your comment very well.
Thanks, so basically even one would make a serious mess of a hand for certain and probably really bad idea to make det cord bracelets!! PS really impressed with your other videos, no one to my knowledge here in the uk uses explosives the way you do. Had no idea you could take the tyre shredding destruction and actually do large scale ultra controlled demo quieter than you could with a hydraulic breaker and with less flying debris! Over here explosives either means terrorist or cordoned off for hundreds of meters for supposedly controlled demo with massive dust clouds and often local property damage. Glad some countries and people such as your self still have common sense and the ability to use things like this so absolutely professionally.
Thanks Adam, I would say that det cord bracelets are definitely out. There are a lot of good uses for explosives that get immediately dismissed because people are just frightened or don't understand.
@@demolitiondavedrillandblast You might not know this but ISIS also makes propaganda films. In which they execute people who do not convert to their cult or are enemies. They use HD cameras to film the executions. They tie people together and light them on fire. They lower a cage with people in it in a swimming pool and film them drowning. They cut people throats slowely. This all with jihad music with edited muslim prayer. What i wanted to say they also have this one where they have about 5 people lined up on their knees, and they have detonation wire around their necks and they blow their head off. I know i am a depraved person by watching these videos but its good to know what you can expect what can happen if you come in contact with these people. The news largely censors the horrors what they do.
I prefer cardboard detonators, that way you eliminate any chance of a shrapnel accident. Of coarse I make my own detonators using nickel hydrazine nitrate as the insensitive primary.
I have to confess that I know little about the chemistry of explosives other than that it belongs in the "don't try this at home" department. I read up on NHN on Wiki, interesting NHN has half of the friction sensitivity of PETN (which is pretty safe with appropriate care). FYI I believe that the supposed safe distance for shrapnel exposure for regular detonators is 15m. Having said that though, I know somebody that was noticeably hit by a fragment at a greater distance.
Nonelectric and electric caps are made totally inert by putting them in a plastic bucket with diesel fuel and acetone for a few days . They make an interesting fire later . Thanks for your video .Stay safe and all the best.
Not an approved method here QM and not as entertaining. So I'm thinking that the acetone dissolves the rubber seal and the diesel desensitizes / ruins the PETN??
@@demolitiondavedrillandblast I'm contemplating what the "approved method" must be there. The idea of recovering unexploded blasting caps does not appeal to me. Were I to use an explosive to detonate as many caps as shown , it would be with a high velocity shape charge and in the ground. The ingredients of caps are hygroscopic = Yes, The diesel fuel ,isopropyl alcohol , common gasoline etc. ,makes the "PETN" or whatever component inert. Using Det cord unnecessarily is not on my agenda. ATB
Well... actually you are third... I just took down that first version of this video and loaded this version as there was a problem with the first. One thing that you can be sure of is that there will be more booms!
Old explosives can be unreliable, in this case old plain detonators are well known to absorb moisture and become very unreliable, a blast failure in the making, not to much of a drama if it is a single hole but in a multi hole shot, it is a wholl different issue! There is nothing like digging up unfired explosives to destroy your reputation, not even taking into account the safe recovery of such.
@@demolitiondavedrillandblast i guess fuze cord can get wet ok but i never witnessed a blasting cap lose its mojo due to moisture...and still u can load them in a borehole with the rest of a charge...why play around with meters of detCord and tape to dispose of them?
Ah! very nice but childish, blowing up a steel belted Tyre and a 20 liter steel can in a working paddock. Sharp metal shrapnel every! Great for farm stock and kids to come adrift!
That got the sheep moving!

Oh heck yeah! It is surprising how small a pile of super fine black powder it takes to self confine enough to make a bang.

Sounds so much more substantial than potassium perchlorate and aluminum, right.
Yeah, PETN is very substantial bang!

Can not have a dead hole that is loaded but, did not go bang not good at all.
Not good at all!

You could do that, there some sheep in the background.
The sheep are still running!! you call those old and unreliable, looks like they did the job...
Oh they sure did go bang Richard, you would never use them in a job though as there is a small chance that one might no go bang when you need it to.

Not recovered from missfires, just very old and not reliable. Approved method is detonation along with some known good explosive.
