safecracking?

[Batlow]

simple question
why can't you just oxy (or plasma-cut) through the side or front of a safe?
does the lamination have an effect on such methords?

Next question: does anyone know the security measures of the sort of people who take the contence of a safe to a bank eg armavan ect
I mean the heist shown in heat seems too easy and in that you hit several safes at once

thanks

Well, generally safes are pretty thick, and would take a bit of time to cut through. Using a OAT cuts the metal by using heat. All of that heat (well, a lot of that heat) will transfer into the safe, turning it into a very expensive oven, possibly (generally) ruining whatever valuables may be in them.. PC's will do this too, but to a lesser degree, because they work a helluva lot faster.

The technique used in Heat involved what is called a "framed cutting charge," which despite it's expedient field use is quite difficult to prepare. It utilizes a principle of physics known as "The platter effect" wherin the charge instanlty melts and pushes away the metal. Too little explosive and the charge won't cut. Too much and you will shatter the items you're trying to recover. Making things more difficult, many safes used by financial institutions are reinforced with concrete (which has a very high specific heat,) and random re-bar (an excellent heat sink), making precise calculation of charge size next to impossible. Becoming proficient in dems requires at least a masters degree in physics.

It's the Monroe effect. You have a specially shaped metal liner attached to the explosive which is turned into a 'liquid' metal jet with extremely high speed and penetration power.
But you certainly need a good level of expertise to be able to assemble a decent linear shaped charge from blasting cord as was done in Heat.
And if you think the heist was easy then you need to watch it again and think about how much planning goes into such an enterprise.

As for cutting torches, apart from the stated facts, there's also the problem that many manufacturers nowadays employ special concrete mixtures that emit a lot of smoke when you use a torch or cutting lance. And a torch is not always as quick as it looks like.

[SFGOON]

The Platter effect and the Monroe effect are two very simmilar things but there are important differences. The Platter effect occurs when you pack explosives on one end of a sheet of metal then prime it in the exact centre opposite the metal. (Manholes work well for this.) When detonated, it blasts the metal in a very predictable direction and with some practice it is possible to reliably hit an object about the size of a 50-gallon drum some 60 meters out with it.

The Monroe effect is an advanced version of this concept and is often referred to as a "Shaped Charge." It is a concave explosive "lens" that focuses the majority of the explosion in a single direction. When lined with metal, (generally copper, if I'm not mistaken,) the resuling jet will slice CLEANLY through almost anything. It's very impressive. In both cases the brisance of the explosive has to be above 1.20

All this, of course, has NOTHING to do with Safecracking.

Watching engineers trying to cut through a Safe,
First they tried angle grinder, (didnt work),
Then tried using Oxy,( But the fumes from the paint,Reacted to being burnt, so everyone had to leave the office.

Then they returned with masks, and finally got the door open, Only to find out, the rear of the safe was actully missing, and it was just pushed against the wall.

Still laughing,,,:)

safecracking isnt a ez task, but it is possible believe me... i dont kno howto without harming the safe but it may require force
(explosive charge,cone shaped object,shrapnels of...metal or watever...)
point the cone at the safe and ignite... the shrapnels will break thru the safe dependeing on wat type of safe...

Did you read any of the above, more legible replys, or were you repeating the answers in an attempt to be a post-whore?

*sigh*

I just did a Marso!

What about thermite (Up to 3000 degrees celcius)? And it can be contained to a smaller spot.

[Ultimatederrenfan]

You could possibly use thermite but you are again faced witht he same problem of possibly destroying the internals of the safe:


Although the reactants are stable at room temperature, when they are exposed to sufficient heat to ignite, they burn with an extremely intense exothermic reaction. The products emerge as liquids due to the high temperatures reached (with iron (III) oxide, commonly 3000°C or more).

This may not burn thourgh, dependant on the thickness, it may burn all the way through and destroy the contents, or it may destroy something you don't want to, like advanced safes, I think, have 2 cobalt metal bars that shoot into place when a piece of metal is smashed (prevents drilling)

So overall you could use termite, but it depends on you and the contents of the safe, becuase it may just be cheaper to call a locksmith to open it that claim insurance or whatever on the contents.

hope i was of some help guys,

This basically says

[Ultimatederrenfan]

For some reason, i can;t edit my post above, i meant to say there was a piece of glass, rather than metal, but i could be wrong, anyone here skilled in the art of safecracking???

There are many different types of safe to suit the many different requirements.
Call a professional Safe Engineer/Locksmith and they will carry out a professional opening.
Idiots with disc grinders and cutting torches are not Safe Engineers.
A high security safe will have resistance to all forms of brute force attack including drilling and plasma cutting. Glass plate is one such form of protection.
A friend recently burned the contents of a safe just by drilling a hole, a tiny spark from the hot drill as it broke through started a fire. Never mind what a cutting lance would do.

[Ultimatederrenfan]

yep, i woudl just call a professional lock/safe opener, like i said above
