Okay. I'm John Buck right I'm back with -- engineering from what training minutes if you've been following along -- series we've been trying to. Teach everyone how to deal with common fortifications. And in this next series we're going to be dealing with chain link fences. Which if -- found everywhere they're gonna fly and simple residential fences which are really boundary -- Up to watch some fairly high security commercial interest. All the way up through argument at a prison in your response or something like that which is gonna have a really torn and really had brigade and our -- security. -- expenses. Many -- -- my career I've come against link fences either trying to stretch -- lines. Are trying to -- the patient -- an -- -- investigation. -- -- smoke there's something like that. And if you're and I wanted to -- about that you've got to run into the so what we're gonna try to do in this in this first -- series is teach you how to look at these with an educated -- -- and -- decides that scale. They're there -- similarly constructed but they have variations which will enhance. -- detract from some of the evolution that we're gonna try to what you can do. Now. When you look at this fences. You want to try to figure out. What that. Variation days. And consider how much damage are willing to do how much time you what tools are allowed and what your goal is are you trying to access and transport a patient. Torn it place a line or advance a line or are you trying to -- to -- -- -- department personnel or rescue personnel. All of those factors will come together in your site up and what I'm really trying to encourage you to do is look before you leap through the -- that let's take a look at -- expenses are made. This is a very simple residential. Gate but it has all the features that you're gonna find -- even the very high security offenses. They all have in common is that they created out of this well. Why -- lattice it's known in the trade as -- -- fabric wide white fabric. Yes spacing can be tighter like defense behind me which is higher security part of decline. The gauge can be like -- like this -- or it could be thicker like this spent. Under any case. It's gonna have some type of support if they have a top -- it may just have -- water it may have nothing. It may have a bottom -- or to the wire. It'll be tied at regular intervals with -- applies to produce -- pretty -- to cut. And then it's gonna get -- horizontally. Using these pension laws. Which slide through the fabric. And then using either mechanical device or -- simple installation like this might be done by hand. Watch events like this might well you come along the fence is gonna get tension. And then attached. You're either line polls or it and post using this -- The light poles. Would be found. Roughly every ten -- typically. Long installation. This -- typical line calls. That can be thick dead they can have a greater diameter or variety out more substantial -- And then -- -- -- changes angle. -- comes against the gate. It's gonna -- a -- post these are thicker. Greater diameter and more securely anchored all of these speeches. All need to be appraised before you Begin. -- evolution you're gonna use to get through these these -- or gonna influence how well or how poorly. Your choice is known to help you. Consider the time fact that that -- -- -- trying to accomplish. The amount down if you're willing to occur and all those things all live together. Would help her successful operation and you can decide which of the several evolution -- we're gonna present to you you should use. I'm not gonna -- threw. Just one example of that size up. We have in this scenario. We added. -- very heavily used highway above us -- call comes in for. On major. Motor vehicle accident. -- -- -- -- -- -- They're up on that elevated highway they find that one of the vehicles in this high speed crash. Left the highway and has crashed down incidents outside part of the highway. A second unit might get better information. They're gonna access from this vantage point and they come against expects. In this instance what am -- looking -- I don't have a top rail. It's just the water up there. That's typical for a long highways I don't think they want the horizontal -- because people can get. -- by them so typically you're gonna -- just the fabric with a wire or nothing along highways. It has a tightly. And has -- heavy gates this would suggest maybe I could out of this but missing that top rail. And also I'm dealing with -- Accessing patient transport. And I might have to get -- equipment in their personal something like that this is really a poor choice for those. I'm gonna do a little more size up I'm gonna walk around the -- take a look maybe it's late at night this might not be obvious to look before you -- take the time to size up. America -- and we'll see what we find. What -- encouraging his take a few seconds to run through a little bit more size up and as I rounded dispensed what -- lifeline. It's at its lowest security much easier to manipulate this fabric. It's poorly tension so we might -- get rid of this right away it's it's only held on by one strand. -- what are you know. Looking at it brought up the slope yet and defense has already been removed so we -- do -- more patient care all of our extra attention walk -- in and out. Via that access and -- done. Point is look. -- -- the fence and careful detail think of the principles that we're gonna teach you and then take a good look before you thought your operation of the federal. I'm John Buck -- -- -- -- -- minutes that's watching we'll see young and its auditors.
