Initial Scene Size-Up

Mon, 9 Jul 2012|

This free program from the Firefighters Support Foundation defines initial scene size-up and when it should occur. It explains the components of a good size-up and explains the notification and communication process involved.



In this then we're gonna talk -- initial -- size up. With the initial -- -- that we're looking at what is going on on the -- seen. We're looking at the for the -- different components and what we need to know before we actually make entry into a building. Now we're gonna talk about some primary objectives here peripheral -- initial -- size up we will see what does that mean. -- how does it affect you with our fire. The -- term -- initial -- -- that should occur. Third we're gonna explain the components of initial -- size up and a fourth explain the notification process. Now all of these are very important because it's not just issue of you understanding what's going on. To the call you're responding to what is well communicating that out to everyone else does and -- and then responding. So let's get started. Now before we get started to get too foreign in this -- wanna talk about why his initial same size of important. Why it is so critical when you first roll up to make sure that you do this well first -- look at this first picture when you first take a look. You see that this everything seems to be in the roof area along the top as it. Natural impression will be that as an attic fire or something along that lines. However. Take a closer look when we actually take -- look completely around the building. If you walk around look at the backside is filling what you'll notice is not only is it going through the root -- and in the upper area but it's also in the second floor. So we see have -- -- rolling up to the windows on the second floor as well as heavy smoke along the route on elm. In addition if he also -- the fires extended further -- -- in the national picture that we looked at. We're -- -- -- initially it looked like -- was contained one section of the house where now we can see this much further along. All right let's take another look at and another structure. Now in this case we're looking at a residential home we look at the front we see basically a one story house two car garage. And what appears to be a couple of cable both for the most part your standard standard home. However won't walk around the backs us home what we see now is two stories. A walk out a section there are coming off the basement as wells a number of different components the house -- we need to be aware of and so when you initially to -- when you do your initial size up. We want to make sure that we get all the information we possibly can because of a number of factors first. Is that the -- get a better picture of where your means of -- and -- evacuations going to be. We also get us that we get a better view of where exactly is the fire and where's it going. We also get some good information overall of what we're going to be dealing with and this is critical before -- team goes into. Now so let's take a look at some of the other topics. Are so we've established now why is the size of important and particularly the initial -- size -- But what we -- also first do is come to a common definition and this is very important you hear this a lot in your communications class those. Is that come understanding common terms common knowledge is very important not only in the response but in discussions. Within the station so we want have a good common definition of what is the initials being sized up. And did the definition number -- working with is a rapid mental about it Wei Asian of various factors related to an emergency instant. This should include all angles. Now one of the key terms that will hear pretty regularly is the issue with 360 size up. Now 360 size up -- -- component of this but I would suggest that. We expanded out not only be on the 360. But as well what you probably learned your company author class -- our -- classes. Many cases they will tell you start to size up early on -- around the structure what -- almost suggests that you actually became your size look at history. And it's an issue began making your way to the structure. From history you want to begin collecting data. And seeing what all you you'll run into -- thing. And one question you may be asking yourself is how to supply -- and one of the critical things all I hope you realize after going through this. Is that its initial seeing signs -- applies to everybody everybody will be taken on a roll. Now -- as that first go around the officers going to walk currency or whoever's in that -- role in a far butter proper operator. Or whatever the case. But size up is important to all of us because we can't we each -- have the potential that we could be taking on that role with the Hussein. So while this may access -- -- -- many South Pacific too -- officer. Overall while watching is that it applies to everyone. And what -- start talking about initial scene -- who won't take a look at what are the pieces we need to be looking for. We would come to our definition now -- wanna say. See what are we actually we first get there. What are the type things we need to consider. Now and so what I would not take a look there -- several things. First we should include what type construction we do what are we deal with situations -- construction. Are we deal -- masonry what type of construction -- is involved in this building the world are responding to it. The second is the occupancy. Our responses will be different if we're dealing with a commercial structure during the day. Compared to commercial structure -- night. We also whether we're doing commercial structure or -- a residential. The volume of people -- potential life safety issues as much greater in that commercial structure than it is a residential. There's more that will happen to you. We're also going to take a look at the apparatus and equipment. What do we have coming what type do we need more. Do we need to respond all of them maybe we can -- -- Israel army we need to increase our response. So the app -- equipment this -- can be very critical. -- -- Taking a look at the life hasn't what -- ball -- do we have people inside the building. Do we have people around are there what type of life hasn't will be for people responding. What are the concerns when you look -- them. Is the root stable enough at this point that we can do -- interior -- -- attack all the walls. Our how much of buildings involved so that we can with and understand if it's worth making an interior attack. The next we will look at -- supply what do we have for war supply. And so we know do we -- -- do we have hydrants if not do we have the ability to -- war. Art is what -- sources do we have available to us and proximity that we can use this response. We also want -- look at what -- -- exhilarating and age that we may have that may need. What are some additional those additional resources. That we need to have in place. Or at least coming to deal with a sense of another thing won't take a look at -- the street -- -- street could put conditions. Industry conditions problem. Other -- what are other problems -- of course looking at breath back and -- Are there issues there are so we wanna look at the street conditions we also want to take a look at the accessibility to the -- -- -- now. So if for example we've got one way out of the in another -- way. And is very -- get that press up and down through there that -- -- certainly be a problem is gonna affect the way we do our initial attack. The other thing we want to look at is the weather. With the weather we're we're taking a look at what kind of conditions are other weeks there's no way I see is extreme heat or we do with rain. High winds all of these factors from the whether we want to consider because it's going to affect not only our response. But any type of this is sustained response that we're gonna have to happen. In addition -- -- ill tell us where the fires going or potentially going and what's what exposures do we need to protect. We've -- also one look at the area in general. And so things they're coming to mind is. Looking around and this once they start back at the -- way at the road -- rather than waiting to get up the house. You need to look as you're coming up on the house starting at the street. One look at the -- look at the landscape. Look at what potential things could -- run in two or could become a problem with the response. Are we do a very narrow driveway is there a lot of shrubbery. Are there a lot of truth -- things like this that could be a problem for us. As we're coming up the house were beginning to look what are -- supplies were looking and what's available to with the president down the street. Can we get it up the -- things like that. We also want to look at the location and extent. Where the fire where is -- from what we can see where is the fire again. Where's it going right now where is it seemed to be going to. Help and how much of the structures burned. And or is burning. Because in this situation we've got -- he fired a significant portion of the house has already burned. We may want restrained from doing an interior attacked me one hole laughable thing go next year. And this you can't this you can't tell just by simply sitting in the cab of the truck. You can't do that just by doing it you're going to have to get out. Walk -- the structure. And you get the full view of what's going on. -- and this is very important than many times has forgotten. And no matter how small or how -- the -- we have going. Someone least take that extra few minutes and walk a completely around the structure to get a full view what's going on. -- the last two considerations in this as well look at the time. What time and that is our as a part one -- us that earlier with -- example. -- top and a commercial occupancy. Is going to have a lot more people him in there. Then -- midnight 1 o'clock in the morning residential structure there's less likelihood there'll be someone in the house. At 10 o'clock in the morning as opposed to 10 o'clock at night. So that's holidays going to be a factor -- -- were coming in and we're doing her size up. And then finally the -- And this room take a look at what are we dealing with there are other additional resource there's -- but when you call them are there -- -- Are we going to do attack with -- resource and we've got and so forth. Now so these are these are all the considerations and other -- what a lot of book. We've got a simple way of remembering the -- And I think this will help well but the key is to make sure you get as much -- -- information. As you can. Before you make your attack so that is what you decide you how you're going to approach this. Can. Be validated. Candy can assure you the potential other risks that you could run into. As well listen are you take an unnecessary risks. -- a very simple way to remember this is through the acronym Cole was well. And -- think keeping that in the back of mine coal was well. War is the first letter -- the terms. That I just talked about and so this is a very easy way to kind of keep in the back -- -- account formulate your mind what you need to be looking for. Now you may not be able to catch all by specific term. But what we are look I am looking for is that you're able to take this -- least understand. The information you're trying to gather. Now one of the things that comes up is win -- -- -- -- and trying to get information on this and the the best thing I can recommend. Is to court -- as soon as you get on the truck soon as you go on -- Go ahead and try to start gathering information. For example it. Win the -- comes over provides the call information. One of the things that -- you listen for is where was the call made from. -- of the calls made from around the resident. And that they suggest they're smoking in the house that's -- a little bit. That's a good a little better information for me that -- the call comes in from the neighbor's house. So we hear 1 o'clock the morning work on now for a structure fire and I hear that the the call came from a neighbor -- so they saw something across the street or next door that tells you probably got something really is pretty significant -- That there -- -- and -- them -- So those -- little -- the other thing you can do is as you're going to the scene. Try to gather as much information or relay information to the -- forget together. Now this may create a bit of chatter going back and forth but if you have -- through it if the based on that initial phone you've got the impression you've got -- working structure fire. You want to go ahead and gather as much as you possibly can on the way. And so take advantage of the fact that this -- talking to somebody -- -- continue relaying the information two years ago. With this that we wanna take a look at some one simple -- -- -- further maybe and this'll help considerably as well. When you're when you're providing this initial scenes size up you -- aunt -- asking yourself three basic questions. The first one is what the what have going on. Now this may sound very sound simple all surface of the -- so. Okay they call those social structure fire that -- car fire whatever the case may be. And so we know -- -- But -- -- -- a little bit deeper based on your pre plans based on your riding around in the community based and on being out in those areas. You can begin to -- from your memory take a look at some of what exactly. Do you have and what's going on. And so for example -- you neighborhood you were just there last week you were caught call infrastructure part of their you can try to remember okay which house -- -- what does it look like. What stylus. How many stories all these questions we -- or. Objects were looking at earlier. We can come back to again and see if that helps trigger some memories of what what type of situation we have going on. The second question is how and where is it going. How we're going what -- thinking you know here is how was -- moving through the house. Where's it going through that -- that the structure. And what are the potential hazards I could run into. So we want to take a look at how is this thing moving and what's going on. And again falling back to what we got so we're pulling that we're now -- -- -- questions together. And the third question -- -- look at is what 21 need to control what. And what they should trigger for you is -- wanted to -- additional apparatus. Cannot handle what -- got. Are there it is there any special equipment -- -- have -- And so these are different things when you look at so for example the puck out of our car part -- -- fuel. Maybe I -- see if that doesn't nearest airport has a our truck they consent. You know maybe something with phone that we can use to fight this thing if we're dealing with -- and older structure. Maybe is instead of just using word by the far we've we've got a unit that we get as close by that -- -- call for that has compressed air phone. So there are a number of things we can look at two on the way to the scene and as we're doing this initial size up. To determine what what we need to bring to this. So this is some of the things that need to be rolling through your mind. What do I have going on how where's it going and what do I mean you can dues to control. And so -- that he should be you can develop pretty close good plan of attack. Right now we talked about what you need one of the components -- look at four sides up. One of the things we need to make sure we understand as well as it is not just having that information. Is that being able to transmit it and send it out to everybody else responding. And this is this is this is important because keep in mind in many cases depending on what your department is that she's our. It's not just -- beat you running the -- you're gonna have other departments. Responding as well. In addition if your department the response to the -- then call -- mutually. More than likely if you've got something significant other departments will be listening so you wanna make sure that you. For a -- are able to transmit this information effectively. Now what are some things it should be in that initial transmission. First -- you need to -- them up by your unit arriving -- saying. Engine one. -- -- one. Glendale and -- want 45 it whatever -- name goes with your unit. You need to clearly identify that for the dispatch. Second to find what you have. Do you have -- low single Storey residential structure to store residential structure. Do you have a commercial structure. Two stories so for all down -- you kind of get the idea what. We want to make sure it's very clear and very brief what the what exactly do we have here Hussein. And then the third thing and this is this is important for as the scene progresses. You wanna go ahead and establish command. And the reason for that is that begins to tell. Everybody else who they need to start talking to. And this is sometimes not -- you'll see it done as much as it should but. Once you've established that command -- against a line everything we're supposed to go people know who to contact when they wanna get there -- And sure it's gonna change as the Seymour senior officers arrived. But you wanna make sure at least to get started from the -- So in our system they sold more tarmac is we say you're -- fired units. You talk about you define what you have. And then you must tell -- command so well in an example of this would be. Engine why don't -- we have a single Storey residential structure white smoke showing. -- -- -- -- -- And then dispatched to come back and acknowledge what you're doing and so -- because. This doesn't load up the radio channel doesn't look radiant communications -- I have heard some. Sometimes get on the radio and they give you the complete. Synopsis of the incidents sounds more like a novel than just a brief description. I move -- -- you wanna be brief about this but you also want to be clear. And so. Simply identifying those three things identify your units. Tell what you have and then establish command. And you're set to go up. Let's take a few minutes let's go to an example or two and so we can get an understanding of what all we're looking for a mission to size up. I've got a sample drawn here and I'll -- residential. Structure that I want to take a look at let's go through some different scenarios that would potentially run into it. Now first all the talk about is when you get to when you think when you begin your size. You wanna start from the street. And that this is very or because you wanna -- Clear as to what the path is our what the concerns are all of those types as well what additional resources humanity. So in this situation. As we're coming up on the driveway if -- coming from this site. -- we do we do we begin looking for we have to move along with the driveway here we see there's a tree. On both sides -- potential patent for the truck. As are coming through a very narrow driveway as well as this through here probably -- Going into the garage that could actually create problems -- if everybody responds up. Through to drop away. And this is one of things like to -- like to do Aussie you went up first an engine -- it's very narrow problem Weyers will be very hard to get apparatus in and out of there. One of the things but doing the size of the ways you can tell the other people responding to state back in the street and not just sort of -- into the droplet. Now want things if you look here. Recalls of where we're located coming in we may or may not see the hydrant -- here. And so -- work pre planning is will be very important the calls. Coming into this thing we very well because of -- bush sitting right here we may not Gibson either so we would need to know that. In addition as you come -- crawls. Come up we see -- the -- here two car garage. This -- here. We also see there shrubbery near the content to be a problem -- we're getting up to the house and trying to pull those up to the house. We look here -- as well there's an entrance to the and the house here this airs. But it didn't -- -- make sure we do before we start trying to pull lining go into the house. Would want to -- who wanted to make sure we do a complete rethink if you walk around. So that we can have a pretty good idea what we have. So we continue -- we cedars. And to -- -- trip hazards or has it right here from the tree. This is very important. To see here. We've got a swimming pool backyard. At night particularly with swimming pools that they're not -- install. Or they're not mark they can be very Park City so we won't be aware of that as a hazard. We also noticed there's -- here that we need to be aware -- for some reason either coming out the entrance. Or coming out of -- before we would need to get more information we pick that up as we walk around. We also see it's significantly wooded area back over here which could. Tells us that it would there could be issues there to be concerned with if the fire rose to a significant level. Keep in mind depending on what the distance us from the house to this woodland area. If the -- gets out of hand there's a good chance we could also have -- was part deal with -- -- not careful. We continue our walk around we see that we've got a -- Rochus out of -- Rogers wells another tree. Now -- the trees and shrubbery all of those things sound like OK simple enough. But this year dealing with here is these are potential hazards this might get hit from branch has -- -- -- trip over route structures. Trip over shrubbery these could become entanglement -- -- if you're trying to -- -- into the house. All of these are different things that you wanna be aware row and stay clear up. The other thing -- look for are there any other hazards around here that could potentially be trip hazards or things like that. So you want to be cautious ahead and do you walk around. And so that'll -- that -- -- ideal of some of the things we won't look for and find it here. Another thing you may want to take a look at is -- Panel box electrical panels where those located around here. One of -- sources that we would need to be aware of -- -- walk around the house. So those those are -- some considerations look at. We'll take a look now a second example we we talked about should use basically. How we well some of the things we'll look for a little walk around but now -- -- -- take a listen let's get a scenario going to see what happens. And in this particular situation we have but the same residential structure out of the men's minor changes we want to make sure -- The second thing is that we've actually got to -- in this situation for running your garage fire we've got that going right now and it's pretty that we got flames and smoke visible in the garage. So as you come in and -- coming in from this direction. We're coming now from design. And one of the things we see immediately obvious we've got -- Trevor is concern here when we come in. We see well that we've got to -- right here. So we pick right up on that. And then as we progress along onto the -- would NC we've got strawberry. Trees here trees here shrubbery here. We see there's an interest you to the front door and window. In this particular case now again. We want to make sure each time no matter how big or how small this -- maybe. We want to make sure we don't get the tunnel vision going the television's gonna say let's go ahead -- here -- -- right here in the fire knocked out. All of a second before we get too far in this make sure you do that 360 walk around. All right by doing that what happens -- in this case again we see the same tree here. We've got a little bit different situation now we continue walking around little kids -- says right here. That's gonna create a trip -- for our potential -- for some might get tangled in so we wanna be aware of that begin with. As we come -- -- here's and this is something we we need to pick up on we see a gas -- leaned up against the wall. Now one of the things that keep a -- with a when you see something like that is one of the potential hazards -- -- run into. In this case we could have a propane tank or something along the lines that could be involved holes of the park the end. So we we -- to definitely be aware of this right away. As we move around. We can -- receive it here are -- that we talked about is going is there apparently been an hour window. And then we continue -- around we have retrieved more hazards -- -- -- the issues that we need to -- with this was the wooded area back here. Now. Keep in mind if the wind for example we talked about weather conditions. If the wind is blowing this way is -- pushed apart back toward here and we've got obviously the tree area but for the most part we've got pretty clear to work well. However if the wind has fallen because one. We've got a potential this is pushing back in this wooded area. If the winds come from this direction we have a very well likely possibility that this is gone with the wind could help move -- back into the house. Area based on what we've seen so far of this is that nothing has moved into the house. And they're they're in coming from this directions is -- -- about the split. And possibly could push into the house again. So the wind this is for the weather will be -- serious factor so now we've seen some additional concerns here at smooth guest really could be a potential explosion -- We've got -- peasants here with -- swings. We see that do you shrubbery or trees where those -- all they can look at that could create problems for -- that's awful trip hazards. And as well all week we begin to see you can walk around here. There's no fire that moved into the house so that the pirates rip this thing in the garage at this point by the -- we get here. That's -- -- along with someone here -- to note. Nicole what happens is the tendency is we get the tunnel vision and we pulled appears start pushed by pulled the garage door start fighting the fire. Which is a very common practice. -- -- potentially could have done was push the fire back -- the gas grill or pushed it back into the house. And this is one of the reasons you hearsay that you've got a garage plug par like this. And you've got no did not know if you've moved -- the house it might be a better option. But to come -- through the front door and go to the kitchen. In this particular case and push the -- -- from the unburned section. And there's so doing this 360 give us quite a bit of information work well. It also tells what specific -- we got to worry about. And be concerned with the so that we don't get surprise. And that this is the idea with a 360 you walk -- and -- national -- size -- Is to avoid the surprises we don't want five get into a situation upon a -- -- we get in trouble. Or we get ourselves trapped or potentially -- an explosion or salt of that nature. So -- making sure you take that extra few minutes to walk around instructors see what you have see what type of situation yet. Getting that information gathered to see what type of hazard should you be concerned -- as well as what type of potential things you could run into. And then relaying that information back to the communication center back to the dispatcher into the other units responding. This way that's a good communication whoa what's going on. And as well as the other units start arriving they can assist to be a better resource for you rather than trying to find out what they need to do. So did that the of that initial -- size up the walk around all of these pieces are critical to the success of our response. We need to know what we're dealing with a four -- again. Give make me any type of operations. We also need to be aware of what happens after running into -- and if we needed doing interior attacked or -- back out into an exterior. Previously we just looked at a residential structure at some of the things that we need to. Keep in consideration as we're doing our size up. Now a take a minute take a look at the commercial structures scenario. And that the draw we have here we have much shopping center that with -- a variety of stores that we need to be aware of on -- what I restored here we've got a group restore. We've got shopping carts here like -- loading dock opened back in a dumpster. We've also got a hair salon a pet store movie rental. We've got a beauty supply place. A hobby shop. Computer store and then a drugstore over here again -- -- loading dock front entrance area now we've got to hydrants. On -- side here and then back here we've also got a dumpster. To dumpsters that are part of so it the rest these are alliance. And then -- four of my time and then in through here are probably our parking. Again what we're going back to what we initially talked about. Was the issue -- beginning our size up from the street. So -- -- you come -- you gain visibility of this shopping -- you wanna begin looking for the concerns and issues. Now in this case as we need to do begin to do our walk around. We will see we've received that we got -- glass fronts -- all of these. We begin to walk relentless that we go loading dock. Here. We've got a -- We've got a hybrid. We will have doors back here that pretty much that's about. A dumpster here and another loading dock. Now these are good these are some of the things we want to make sure we're aware -- first ball where the hikers are located. So that we can find out you know if we need to get additional war supplies if we need to additional resources for war we know where -- -- These dumpsters could be potential problems depending on the fire where the fire is and how and where they're located proximity to the building. And then the -- we want to lose the loading -- public in these can be a benefit or setback. They can give us citizens they provide an alternative way presence could be able to move large amounts of equipment into the the building for fighting the fire. The other drawback is as they can be fall hazards depending on -- people know Obama not so you can imagine. -- suspect the select comes out of -- or the drugstore with an air attack on. And while you're there visibility is very limited and they -- stuff off actually off the back of the floating dock. And there could be definite potential problems there same thing with the -- restore. So we also tell you look at this these dumpsters again we would they could be potential hazard -- they can also make the situation a lot worse. With the -- whatever it is stored in here. We've got covered areas here sidewalks. These concerns -- depending on what how big the fire -- -- these could potentially collapse fairly quickly. As well we -- take a look at what type of construction the other parts are if they're concrete which is very common. As well what type of -- construction do we -- so do we have a situation where there's potential weak route or. A -- could collapse fairly easily -- when exposed to be. So these are some of the factors we want to consider going around and so we would continue much like we did with a residential structure. And while this may take a little bit longer to go through it this level. This will work because the risks are a lot higher in something like this because it's very easy for someone -- get lost. There's very -- it easy for someone to get. The lose direction in and going out -- or different northerly anticipated. There's opportunities here for other type of -- -- chemicals that could be stored things like that that could increase the level -- are. Or -- number of other things to look for so we want to take it for Tom. -- won't go completely around -- to notice what things we need are. Are available to what information is available to us. -- continue. Noting -- dumpsters noting weren't exits are free to these buildings. All the back. Continue yes we now goes to the loading dock we -- a -- here. And then we continue around. And we've got open and this this is beneficial is big parking lot calls now we know we've got we've got a fairly good area for staging. Where in the previous example you know she had a very narrow probably it's those very -- -- apparatus and out of there. We're here we've got a fairly large parking lot so we've got the ability to state more apparatus secure we played some of -- better situation we -- at the residential structure. And this is one of the things as you're going through into your walk -- consider where you would be placing apparatus depending I was near you have here. And what the situation may -- So that that gives you an idea -- what are some of the things you -- look for in -- on the key components you need to consider when your do dealing with us. Now let's take a look at a couple scenarios and -- plywood floor apartment class the first politics we'll show you is that we've got to dumpster fire. On the back side of the grocery store in the shopping center. Now again it seems like a very simple call the problem is simple call can easily turn into major -- if not addressed properly. And this is what want to make sure this when we come then. We come into the parking lot we've got our response and everything and we see we've got fighters here. We've got a fairly open parking lot as soon as we -- -- were gonna wanna take -- start assessing. What's going on we see multiple shots here the glass fronts the covered sidewalk. We see the lamp posts look through here we see we've got -- Two fighters -- ago and this shopping cart area so that com that's just initial upfront. We continue around. And continue this way we see the -- not in here we -- fire. Now that the key does that initial thing is we we want to continue doing our our going around and see what all we've got. Because one of the things that could have we see we've got a small choir here but again what happens if -- -- that the suddenly everything shifts. The call for example again if we've got wind coming out this direction. There's very likely possibility this is not to be affected north can be -- very mentally. Same situation of the winds coming from here. Coming from here we couldn't have this push back onto the building. And then from -- same situation. It could be pushed back of the building over here. Now consider as well if -- -- pushes back on the building what -- we got we've got to her story be it can see what they've got stored in the back of the grocery store. We've got to Paris -- possible chemicals there we got to deal worth. That's stored here. Again possible chemical's possible other -- that we could be dealing with as well. So we need to be aware of this. So we continue our quick search we've got another fighter here that we could we could use. And that may be one that as we come around and finish our search we make comebacks OK let's get the -- here we needed. So -- what we've done we've because on our search -- or -- -- our initial size up we're gonna come back and begin to deal with a -- itself. Now one of the questions they're again looking at the wind. Looking at what we've got its fourth buildings and all the policy on the backs always probably see it Britain may may or may not be markings. That's why it's important to get always come all the way around and see what's all the -- So we know this this posters here but as we draw around -- we -- okay is back to put hair -- and -- restore. So these are very important concerns -- -- and actually this does not take that long to do. One of the key things with a commercial structure like that this. Is that your hazards increased there's greater possibility. Of getting hurt or injured in one of the and one of these type structures. So that we see in typically with these types storage consider the -- construction on these are very light. So of the collapse rates will be a lot lower so that will be good possibility if there's an art work been working -- here the -- is going to go. So -- won't be aware of this solemn. We collect around if we need to we -- -- -- would pull off we know we don't wanna push the fire back. Onto the building we won't push away from the building if possible so we're also are opposed ones -- so we're we're pushing away from. -- from the building. And as well be able knocked -- are fairly quickly. Now last scenario we took us some more of simple situation but dumpster fire and how to apply the tactics of the initial -- size up. Now let's take it will stoke further it was still an actual structure are shopping center -- fire. In this case we have one from the group restore. And the back -- or near the loading dock we have a fire going. Now -- what -- -- well we're going to be approaching from this side of shopping center. Says we pull up again. Coming into the shopping -- we see your hundred here. And probably if -- Heidi it was no problem. As well we Cyril light posts. We're look at the covers -- walk we're looking in the storefronts. To see what kind of -- we have and stuff like that and then we're gonna pull around this way. Just to change things up a little bit again our second -- here that are loading dock and that would go to the backs of the building. That would -- here another dumpster. Terrific and other -- here. And then we continue -- across. We've got another dumpster here. And then we're gonna spot across here here's worm virus we see we consider rolling on the back of the the loading dock area we don't know what all is in here quite yet but we do receive from there what we got we -- where the fire is located. And we may feel that as we start around we made you -- see group -- who's deeply moved to the store itself forest contained in the back of the building. Now again that with a -- now in the structure. This changes the demand dynamics quite a bit one these are these are typically very open -- us. These -- areas that once the -- gets into it it can move very quickly. And in addition depending on how we approach our attack -- this. It we could either push the fire away from the current portion or just as easily push it into the rest and store and further along the shopping center. As I want to bring up before. With a roof construction of these is that there is a greater likelihood the -- will collapse compared to the residential structure we're looking at earlier. So these are all concerned who want to be aware -- And take a look at so we circle around we begin -- more than likely in this case -- you call for more. Assistance because you don't know how far this part while ago. -- you wanna try to push move your attack in this tape probably through the front. So that you can you kind of push the -- put too far away from the unburned section and back for the birds action. And then from there we we keep away from some leaders put their again here we have a hair salon but -- -- Both of these contain more than like containing chemicals and again -- it pushes along -- very good chance this could push along very quickly through the rest. Depending on what they've got that they've got our break and so forth between here. So it's very simply this is not. This is not a very time consuming thing but it's something -- we've got to make sure gets done. Because had we not done this does this -- This initial size of the 360. Where we -- noticed that we without picked up all the resources one that are available to us. Normally you recognize the you know other hazards until we actually count on them. So this gives you an idea what the how do -- -- do your national size up. The key as well is once you've done so you've got you've gone completely around the building about what -- you've got you -- radio this back to. This back so they can notify the audience and that everybody who's responding had very good information coming into this thing. As well also they can also respond and -- -- refining. Get an idea -- what they need to do to -- to be a part of the response effort. The 360 is a component of the overall initial same size. Other components include checking for -- -- what are your water supplies one additional resources to you have coming. As well communicating back to those resources. No matter what the size of the call the type of call or what you may be coming up on is always important to do -- 360. This way you're you're fully aware of the hazards -- fully aware of what you're going into it. It is just critical that each time you you -- role listening that you provide -- 360. If you look at the national average is now the typical structure are the numbers are going down. And we're seeing less and less than those while we're seeing an increase. And automobile accidents EMS calls and various other types of incidents. So it's very easy when we respond to a structure -- -- typical structure far. That we get the blinders on we want -- race and get far not downing get things handled fairly quickly. However the few minutes it takes to do with 360 walk around to size of -- scene and take a look at what we've got. Can make the difference in what could be a very simple small call and -- become major catastrophe. And it's very important at the company officer level to make sure that when you first -- this thing. While the folks from Poland the -- opposed they're -- -- setting up for war supply. To go through -- to your 360 wall for him. And to make sure that air all the -- everything is covered -- that your crew is safe when they go into the building.
