Sometimes the best option for firefighters looking to gain access is to go around or over the obstacle. John Buckheit shows you how to ladder a chain-link fence and demonstrates pitfalls that can occur with improper laddering.

I'm -- -- about the fire engineering for another -- minutes. We've been discussing it in our series chain link fences. And in the water timeframe forcible entry in general when you think of forcible entry you'd normally think of braking and locking devices something like that what you really have to think there are times when you can just get around or over the obstacle and that's the case expenses. -- -- -- -- -- -- and that's. Going to be your best approach consider that with -- he probably is no damage. And -- you have to consider what your goal is if your goal is. Access. And it's a good option. If it's for one placement it's a fair option and it's. Victim not transport maybe to -- option so think about what you're trying to do and then you have the that's equipment you have the latter's. And then take a look defense. If it has a top rail that's gonna help you have that there is -- top rail that's going to be a hindrance trying to work. Down by the terminal posts if you can they're going to be stronger they're going to be better secured -- -- line -- If you are most of -- latter's are really too long even in the best to position. Aren't the problem is when we put collateral with the proper climbing angle 65%. -- degrees a good portion of the latter is above the top rail if you event -- those rails -- balance. Or stability. The latter can pick out and you because through much of the -- is above that's top -- If you try to go at a very low angle and used a ladder that what you're putting a lot of weight on the fence when you ask your way. With your PP. Maybe another firefighter maybe some equipment. You can -- that grants the whole thing can collapse. And and you want -- really not having -- operation. We're gonna show you now. A classic. But -- the NY evolution. Or how we would get over fence and then we're gonna just quickly demonstrate I didn't get into trouble. If you have too much of that latter but the that. -- -- What we just Dave is that classic at them why evolution we -- used to ladders to create a bridge. To get over -- We have a good climbing angle. And the only way and it really in trouble here is that when I go to transfer to this other latter. If I grab -- high on the latter or on this -- that I'm on it could put too much weight above the top rail a lot of commence these are out. And -- -- moves the reporting of that ladder and demonstrate that right now. I. Right to get real trouble. Want to -- in this latter right to the ground -- I don't have. And SE BA on. I don't have a lot of extra weight I don't have any equipment would be. It's not a problem. But we're all that stuff to being a real serious injury could could tell your operation. There's a few things you can do to avoid it. We're gonna reposition the -- One would be a have a button and somebody at the bottom make it through the -- stays put the -- always -- the bottom. Good defense or when I do make this transfer part of -- -- -- just realized that that can happen so keep you away. Down low -- down low don't live up here that's gonna get into trouble -- down low on this. And make the transfer all the asked some people would be attempted. To put these latter's at a lower angle. And then you won't have so much -- sticking -- top. But you can see that I'm already deflecting this top rail. So with two guys or one guy a bigger guy a guy with full PP and possibly equipment you could wind up crushing a collapse in the top rail. And again you might have on controlled movement that is open to trouble. It. So we've shown you a quick and easy way used to ladders. We use 44 ports they invested fourteen feet. I have about a six foot high rents. So I wind up with -- four feet five feet hanging over the top and experience I can get in trouble with that right. Want to avoid that. That's the one but the latter not to put any weight above the top relish and make -- -- I'm John Buck right and another training and thanks for watching.
