Lieutenant Ray McCormack of the Fire Department of New York reviews some of the fundamental tools and devices for standpipe operations.
One of the items -- stand -- kit should contain is an in line pressure engage this is very important. Because once -- to what happens lines -- It's tough to tell whether it's charged with supercharged. The -- we'll give you the proper reading what pressure you want on fire for depending on how many once you've stretched. Very important tool. Another important -- course. Is the pipe bridge. This heavy duty pipe -- will see us through a lot of problems it will open up stopped Capps pull off any external pressure reducing -- and open up. A valve -- if the -- was missing is very important tool for keeping your kids. Obviously these two tools speak for themselves a -- should definitely have wanted to spend -- in -- -- And wanted to -- to -- opened doors very important. Another item that we have here is they. One way gate some departments use this they'll set their pressure and attach the -- gate and once that's set to whatever opening they want. It'll stay that way and and they can. The issue -- that they have proper -- -- very nice tool but those in an extra week you pack. I hammer alone camera like this can be used to get -- stubborn. Wheels and caps. It's obviously something that you should think about containing -- as well. Hooking up your attack pointed to -- -- Reiser. We should follow sequence of steps. One is we're gonna look at the what's attached to the -- outlet here we have a cap. And an external pressure reducing device over these items have to be removed. It is possible to remove them and steps by removing the cap. If you're not sure that it's an external pressure reducing -- in just remove the cap and take a look into into this. Okay I can see. That. It's an external pressure reducer -- also -- -- -- There's no free flow of movement here. So this has to be removed. As you can see even if this was completely open. It would stop some of our water flow -- we want to remove it. At this point we're gonna open all about and check for Warner. This system is a wet system meaning his what do contained in this system all the time. We're gonna check to see what type -- flow we get by doing that we're gonna clean out any debris that comes up through here. We want to get rid of that debris before it reaches the -- They were gonna put this -- in here from an open up the valve -- -- -- Felt like. And you've seen in my book. Wanna make sure that we get rid of all the -- Don't cheat on this that very point. You -- pressure gauges of vitally important tool in the stamp type operation can. What happens is once this is assembled and on the brighter outlet and -- hoses hooked up to it. We'll get the word to charge the -- -- with water once that happens the -- we'll have a very high agreed. That's not your true reading what you need from -- not a team is for them to open the -- with the -- Warner. Once they've done that the pressure will drop. That's when you actually adjust the valves setting for what pressure you need to at the nozzle. -- we're gonna hook this up to the stamp -- out. Now you tighten it down with the -- Let's look up the -- now as well. -- make voice connection standard type. To be mindful to keep. The pressure gauge -- within viewing distance of your operation you don't want it accuracy can't see what's going. -- -- The firefighter at this position -- wait for the order salt water line would be flake out -- -- open up about. At that point pressure reading would behind like -- said before. Once they open the line depression will drop out of content.
