More Building Construction for Size Up

No comments

Here is a quick look at a building that offers more than one considering in regards to construction characteristics. The building in the photos is currently a resale shop. This building has been a tack shop, lawn equipment, sold boats and trailers. If you look hard at the front, it has been added onto.

 

 

 

 

 

 

 

 

 

 

 

The right side of the building was the original and the left was an addition. The front and side walls are wood frame with a brick veneer. As you can see, there is a parapet wall on three sides of the building. Both sides have been rearranged multiple times on the interior to accommodate the occupant of the moment. The original roof was flat.

 

 

 

 

 

 

 

 

 

 

 

This side view shows some exterior doors and the brick veneer. We can also see the electric service and a boarded up window. This two doors lead to different areas of the building and are not adjoining. You can also see that the parapet wall appears to be very tall and of combustible material.

 

This is the rear view and the most telling about this building. We can see that the back wall is different from the other three walls. The back wall is of block. We can also see that the roof is a lean to type of construction and knowing the history of this building, it is a “rain roof” or “roof over” that covered an old flat roof.

We can also see the parapet wall is brick on the two side walls with support ties. We know that those connections are very likely going to fail during a fire. There is a lot of void space that could be difficult to get to due to the “rain roof” and early collapse of the parapet wall should be expected.

In addition, the importance of the block wall in the back is important for orientation as well. If we get inside and get to a wall that is block, we have a pretty good idea of where we are. We only would know this by pre-planning and/or doing our 360.

These are just a few of the considerations you must think of when presented with this building or one like it. Discuss this with your crews and identify buildings that are similar in your response areas.

Train hard, stay safe, and remember those who have fallen for the lives of others. Please especially remember the families of Chief Kyle Ienn, Firefighter Doug Haase, Chief David Flint, Fire Lt. Kevin West who all left us this week.

High Rise Markings

No comments

If you have a high rise or respond on mutual aid to a high rise district, do you know if they are marked for floor identification? If so, do you know how they corresspond with the interior labels? High rise buildings are marked differently, if at all. In our area the windows are typically marked with a reflective sticker, one on every fifth floor. Where this gets tricky is when the interior floors are labeled differently.

This high rise has red circle on the corner on the fifth floor window and the 15th floor window. You can see them in the top right hand corner of the windows on the right side. Now, some places will actually put numbers on the windows, but we are going to just address this one method. If you count the windows you will notice that it doesn't add up.

This building has eliminated the 13th floor, thus making the floors on floor off if counting. This is where preplanning comes in.

                                                                                                                      

It is important to know how the outside corresponds with the interior. In some of these buildings the ground floor may be labeled as "Ground" or "Lobby" and not the first floor. In addition, if there are penthouse units at the top they may be labeled as such and not given a numerical label on the elevator panel. On this building the 13th floor has been eliminated. It goes from floor 12 to 14. On the photo below you can see that there is no 13 on the panel.

 

 

 

 

 

 

 

 

 

 

We need to get into these buildings and be familiar with the labeling of floors. The last we want to do is deploy to the wrong floor or take an elevator to close to the fire floor. It is also important when searching for victims, knowing what floor is reported and how the occupants will report floor numbers.

This is by no means the only marking systems, just one method. Get out, know your system and train with it.

Anatomy of a Basement Fire

No comments

Here is a short video that you can use for a drill or training night. Feel free to use however you like. This is from a recent basement fire and what was looked for and what was done. There are some considerations to think about. This is not everything for all basement fires. Just a simple tutorial. Feel free to add your experience and ideas to this video.

Stay safe,
Jason

Judge Not….

3 comments

I’ve done it and you’ve done it. It is going to happen again and it’s going to happen soon. With every line of duty death the Monday morning quarterbacks come out and tell us all what they should have or should not have done. We preach and teach to learn from these tragedies by understanding the circumstances surrounding the incident. But, what are we doing to make sure that this doesn’t happen?

Our job is dangerous. Worcester Fire Department is a highly trained department and according to some reports I have gotten, fight these types of fires every year. There are some additional factors like high winds and possibly illegal renovations that compromised the structural integrity of the building. Neither of these two factors can be anticipated or controlled. We have a job to do and when we are told that someone is in a building, we do what we can to get to them. As I write this I have not heard confirmation that there was or was not a victim found.

I have no doubt that we could dissect and scrutinize what happened and we would have done this or that differently. We will hear how simplistic it should have been and others pounding the table that we don’t enter buildings that are compromised. Guess what? As soon as that building catches fire it is compromised!

What frustrates me more is that in the fire service many are real good at solving problems after the fact and few try to identify and solve them before they are actualized. It’s not just judging the YouTube video or a line of duty death, no, it’s many things. “That guy doesn’t know what he’s doing.” “That guideline is outdated and inefficient.” “That small time volunteer fire department doesn’t know what they’re doing.” Of course, most of these “kitchen table experts” have no desire to be proactive or to put themselves out there to take the lead on a project to make a positive change.

Sometimes, and I’m not saying this is the case yet, things are not preventable. Sometimes we are going to lose. We hope not, but we are running into burning, compromised buildings to save lives and property. When someone comes to us and is telling us someone is in the building, if we can make a push, we will and we should. This is what we do and why we are here. There is no time to run down a check list to determine if a certain profile is met. We don’t have time to switch our size up decision making. We have to consider the situation presented to us at the time and use our training and experience to do our best to attempt a rescue.

But, if we do want to be Monday morning quarterbacks I suggest a different approach. Take your expertise and knowledge to some less fortunate departments in regards to resources for training and teach. Share your experience and knowledge with these departments and individuals to keep bad decisions being made on the fire ground. I believe that this is the best way to honor those who have sacrificed their lives for others. Whether there were mistakes or not, we can help to prevent those who don’t have resources to perform appropriately on the fire ground.

We recently did a class in a remote part of our state and had two firefighters arrive with some hand-me down gear and SCBA. Neither had worn the gear before and neither had ever had on an SCBA. They stated they had been fighting fire with self purchased boots, gloves and helmets. That’s it. Nothing more. This is still happening. We had to pull these two firefighters aside and walk them through some basics about gear and SCBA operations. We took extra time with them just to teach them basic firefighter skills. They were more than willing to learn and were eager.

The point is this: let’s put our efforts into training and teaching firefighters to operate safely instead of beating up departments, officers and firefighters after the fact. Can we learn from these tragic events? Absolutely! We should learn lessons in a constructive manner from not just tragic events, but from every call we run. There is always something to learn whether things went well or not so well.

Train, be tolerant and make a difference in a positive way. Stay safe and thanks for reading.

Balloon Frame Construction: From the Inside

2 comments

This short clip show balloon frame construction from the inside. With Engine House Training, LLC this summer, we had the opportunity to hold a class in this building. It was going to be torn down and the interior wall coverings in most of the house had been removed. That exposed the balloon frame construction characteristics that we so often speak of but seldom have the chance to see.

Use this however you like and share it.  Hopefully, this will help someone to better understand the meaning of balloon frame buildings and to ensure proper tactics are used with these structures.

Keep training and pass on your knowledge to others. Share the gift.

Firefighter Mode for Elevators

3 comments

Okay, here is a short video on firefighter mode for elevators. Remember that each jurisdiction should check with their buildings and operational guidelines. This video may not be the only way to operate certain types of elevators but it is indicative of most in our area.

It was asked of me to mention the "HOLD" position.  This position in most elevator cars allows the crew to place the key in the "HOLD" position and exit the car without it getting recalled to the lobby.  When the crew gets back in the car they need to turn back to the "ON" position and take full control of the car again.

The "BYPASS" position is at the lobby control.  This can be used to put the elevator back into normal operation if the alarm system has not reset.  This should be done only after it as been determined that the alarm activation is a malfunction or service related.

Hope that helps.

 

Train hard and thanks for reading.

Apartment Fire Considerations

2 comments

This is another video I put together. I have been getting positive feedback on this format, so I will continue to do this.

We are addressing some concerns and challenges with apartment fires. This building is of the garden apartment style but this same type of building can be a stand alone as well.

As always, this is not the only considerations when looking at apartment fires. Follow your guidelines and get out to your response areas to become familiar with similar buildings.

Until next time, stay safe and ring those bells tomorrow and say a prayer for all of the fallen and their families.

Reading the Building: Just a Glimpse

2 comments

As you may know, I am playing with a different format. It wont be all of the time for every blog, but something a little different. So, here is one based off an article that I did. Please be patient as I work with this. Hopefully, it will enrich your blog reading.

Thanks, and let me know what you think.

One Aspect of the 360

No comments

I understand that all buildings, for various reasons, will not get a 360 performed on it during a fire. But, for those that we do get to job around, we need to understand what we are looking for.

I recently spoke with an acting officer and asked him what he was looking for when performing a 360. His answer was "fire."  I asked what else? The answer came, "ways in."  We need to make sure we are taking advantage of the information being made available to us while we are circling the building.

This post is going to focus on some basement indicators.  The pictures shown below are just examples of things you might see when making the round.  Keep in mind that at night you need to take a hand light.  For example, the wood behind the basement windows below may not be noticeable with shining a light in the windows on the way around.

        

We must pay attention to what we are looking for when conduction the 360. As you can see, we may be faced with some very challenging situations.  Not only do we need to be aware during the initial arrival, but the RIT will need this information as well.

As always, follow you own operational guidelines and train hard.

This and other topics will be discussed during one of my presentations at Fire Rescue International 2011.  I am presenting for the Company Officer Development track and hope to see you there.

Ordinary Buildings and Considerations

2 comments

Looking at these pictures shows us a building of ordinary construction.  These are usually older buildings and the building we see is typical of many downtown areas.  This particular building has storefronts on the main level with multi-family units above.

            

 

What are the main characteristics of ordinary construction and how do they relate to fire operations?

What are some problems we face with this type of building in many downtown areas that will cause us concern?

What are the challenges with apparatus placment, not just with this buildling, but with many small, downtown buildings?

What are our challenges in regards to exposures and how do we address them?

 

These are just a few issues we face with this type of building. It is important to be prepared for a fire in this type of occupancy.  It will be challenging, especially late at night when that upstairs is occupied and as you can see, access is not necessarily fast.

Share your thoughts and experiences and as always, train hard and thanks for reading.

The Daily Drill: Part 3-Forcible Entry

1 comment

Here is another great post from my friend Lance Peeples of the Webster Groves Fire Department in St. Louis County.  Thanks Lance and now for some fire-thinking to occur.

 

Review the following videos and answer the questions:

 

 

 

1.  Who is assigned the “Irons” or “Bar” position on your first alarm assignment?

 

2.  List EVERY tool the forcible entry (FE) firefighter (FF) should carry when he dismounts the apparatus for an alarm investigation at a multiple dwelling.

 

3.  Are these tools mounted near the riding position of the FE FF?

 

4.  Who is the FF on your first alarm who is designated to use the axe to drive the halligan while the FE FF holds the halligan in place?  What tools should he or she carry?  Are they mounted immediately adjacent to that riding position for quick access?

 

5.  Will a Rabbit tool (hydraulic forcible entry HFT) work on a door with angle iron shields?

 

6.  How would you defeat an inward opening door with angle iron shields that cover the entire length of the door?  What if another piece of angle iron (or a “U” channel) was attached to the door frame and thus prevented placing the fork of the halligan between the frame and the angle iron attached to the door?

 

7.  Is it acceptable to attack the hinge side of an apartment door in a multiple dwelling?  Why or why not?

 

8.  At multiple dwelling fires is it standard practice in your department to force an adjacent apartment door before forcing the fire apartment door?  What might be an advantage of doing this?

 

 

9.  Will a Rabbit (HFT) tool work on outward opening door?  What does an outward opening door in a multiple dwelling suggest to you?

 

10.  What do bolt heads projecting through a door suggest?

 

11.  Should the fork bevel be against or away from the door?  What are the advantages and disadvantages of each position?

 

12.  Some departments order halligan tools that are longer than the standard 30” length for increased leverage.  What is a serious disadvantage of longer tools?

Basic Tactical Considerations

7 comments

This post is just a simple challenge of tactical considerations.  The photos that are posted show a single-family house that had fire venting from the C/D corner when first units arrived.  The first in crews could not make the entire hallway on the first push do to intense heat and smoke.

The smoke was banked almost to the floor even with the fire venting from that corner bedroom.

What are some considerations that must be looked at with this fire?  What would be your next plan of action?  Why ist there so much heat and smoke with the fire venting the exterior?  What is your size up?

Share your thoughts and answers with everyone and use this as discussion with your crew.  

As always, train hard and stay safe,

Jason

Standpipe Crowding

3 comments

We have discussed standpipes in the past, but I think it is worth mentioning again. Standpipes in large and high rise buildings are our water source. It is important to know the location of these devices and to ensure that they are not obstructed.

In addition we need to know and understand if they have pressure reducing devices and how that affects our operations.  Study up on these systems and know how to adapt and trouble shoot the stand pipes in your area.

The picture shown is a stand pipe in a hotel. I went to ice in the hotel I was staying in and this was right next to the ice machine.  I didn't measure it, but this standpipe would be very difficult to connect to. Additionally, if we did get connected with hose only, there would certainly be a kink at the coupling, further reducing our pressure.  

This might be a time when we would try to put an elbow on the connection prior to connecting our hose.  However, I think that with this particular standpipe connection, it would be a stretch just to get the elbow connected as well.

Know your buildings and their systems. Prepare for these types of problems and come up with solutions before you have a fire. Thanks for reading and train hard.

The Door to Nowhere

4 comments

We have all been taught to control the door. I have watched countless firefighters try to kick in doors, bulldoze their way through them along with every other tactic that does not include a set of irons.  Here is one reason why control in forcing doors is so important.

This door is in a city hall that my son was practicing in. The area that the door is in used to be a balcony that goes all the way around the gym with two doors that lead to the main floor of city hall.  Over the years, as they ran out of space, they began to make office space on that balcony.  

The door is almost always locked and access to this area is likely to be searched during a fire.  The hazard here is obvious, but the lesson for any situations: control.

By using proper forcible entry techniques with a set of tools, you can control the door and be cautious about what is behind it.  A fall from this door could be disasterous. We have to be ever diligent to master the basics.  A lack of basic forcible entry skills could result in a Mayday and RIT situation which makes a hazardous situation even more so.

Be smart, know your area and train hard. Master those basic skills and require it of your crew if your the boss. Stay safe and thanks for reading.

What’s Your Take?

1 comment

I spend a lot of time looking at buildings and thinking about "how would I do this or that" and what kinds of challenges would exist should a fire happen.  It drives my wife nuts! You know what I mean? You go to an establishment or an event and you are looking around for exits, sprinklers, fire alarms and just the general layout of the building.

It is good for us to identify these different characteristics on a frequent basis. Even if it isn't in your area, I believe it keeps you sharp. It's like practicing all of the things you have learned in your head.  Granted, you aren't manipulating a tool or pulling a line, but you can do all of those things in your head.  What would you do with this type of door? How about this wierd little addition and the ventilation problems that it poses? These are all considerations you can do any time and any where.

Here a few pictures from a recent trip to Nashivelle, TN.  We were walking back from LP Field after the half-marathon and this building was right next to the pedestrian bridge we were on.  I stopped and started taking pictures and thinking. Of course I got behind and my wife had to explain to everyone else in the group that I was a just a wierd firefighter who does this all of the time.

Take a look and share what you see and all of the different considerations and challenges that could be recognized during a fire in this buillding.

Take care and train hard.

Where Goes the Second Line?

No comments

We all know that it is easy to fall into a rut when it comes to training and even operating at what is labeled the "routine" call. Especially for those that are in suburban, mostly bedroom communities.  

If your like most of the country, you pull past the house to get three sides, stretch a pre-connected hand line and make entry into the front door.  Does this sound familiar to anyone?  And, more times than not, this works just fine.

However, sometimes the bigger issue becomes where to take the second line? What apparatus does it come from and what size should it be?  What about the length?

For most single-family, single story homes, line placement becomes mundane and we get a bit complacent.  The second line many times gets pulled from the same rig as the attack line and goes in the same door as the attack line.

Again, I prefer a seconday apparatus for the back up line, but in most house fires the front door is appropriate for the back up line too.  Of course, it all depends on what is taking place and many other variables as well.

One of the biggest problems I see quite often is on two story house fires.  The first line goes to the fire up stairs and the back up line is at the door.  One of the primary concerns is the integrity of those stairs.  That second line needs to go to the stairs to protect the egress for the crew operating on the second floor.

The same has to be done if you have an attack team on the first floor and a search team on the second; a line needs to be deployed to the stairs.  We must protect that  egress point.  In addition, note changing conditions to the search team and the attack team.  Maybe the fire has spread or can't be found by the attack team and your observations are important.

What are your operational guidelines for the back up line?  Share you experiences and thoughts.

As always, stay safe and train hard.

Basement Rescue Video

4 comments

Here is a great video of some basement removal techniques.   This is another video from Dale Pekel, who looks like he may have gotten a promotion? Dale?  Anyway, these props are able to be used for multiple drills and Dale is very generous with how to build them.

These two techniques are great and you can see that one must be comfortable and well trained in the use of the SCBA. Confidence comes from continued use and training.  You must master the basics and know your tools like the back of your hand.  This allows you to perform the more advanced tasks without worrying about the simple things because they become second nature.

Train hard and stay safe. Thanks Dale for another great video.

Basement Considerations

No comments

With the recent posts about the anniversary of the Colerain-Township LODD from 2008, I thought I would provide some thoughts about basements and some of the things we can do to better prepare.

It recent years it seems we hear a lot about firefighters being killed and injured in residential fires where the basement was involved.  There are a few reasons for this including changing building construction as in the use of engineered i-joists and the heavy fire loads that we have in basements.  In addition, most houses with basements don't just use them for storage anymore. Basements are used as active living spaces increasing activity, heating and electrical demands that were not always present in the past.

One thing that we can do to help prevent some of these issues is to know what we are dealing with.  Probably one of the most important tasks a fire officer can do when arriving on the scene of a residential fire is to complete a 360 walk around of that building.  This gives us information we cannot obtain by darting for the front door.

By seeing all four sides of the fire building we can see if the seat of the fire is in the basement and may allow us a more direct attack from the same level as the fire reducing the chances of floor failure.  We are also able to see hazards that impede our egress if a quick escape is necessary.  It gives us an idea of our options for ventilation and fire control.

The pictures show some of the hazards that we can find and keep mind of during our 360.  Exterior stair wells are altered and secured causing us difficulty making an egress.  This is a perfect time for the first due officer to relay these findings to the next due or the RIT crew.  These other units should cut locks, open bulk heads and make sure the egress points of the basement are accessible.

Additionally, we need to know the characteristics of the buildings in our still area.  This is a picture of a house that is approximately 50 years old and the stairs to the basement are in the garage.  Not knowing this could put our initial attack team at risk by searching the main level while fire is burning under them increasing the chances of a failure.  Some of these homes have no outside exit and we must protect the stairs for the basement crew just like we would for a crew that ascend to a floor above us.

Take some time to look around your area and discuss these issues with your crew.  Prepare your newer members for that thermal layer as you descend the stairs into a basement.  We all know what that first experience is like.  Train hard and don't forget to do that 360, it may just save your life.

Train hard and stay safe,

Jason

Kitchen Suppression Dump Test and Suggestion

4 comments

Some devastating fires have occurred in commercial cooking establishments.  We all know the history of fast food restaurant fires and the toll they can have on a fire department if the fire is not found early.

Kitchen suppression systems are designed to activate to limit the effects of a grease fire in these establishments. It is important to note that when these fires occur and the system is activated, the return air should shut off and the hood vent should activate if it is not already on.

When these systems are designed they are equipment specific. Meaning that the flow points are determined by the type of cooking appliance and its location under the hood and suppression system. Moving or replacing any appliance requires reevaluation of the system and could mean an alteration to keep the system adequate.

As you can see in the picture, the appliance shown has wheels.  This could create a problem in the future when the ownership wants to move things around a bit and could be detrimental to the effectiveness of the system. One suggestion is to adopt a local ordinance that requires these wheels to be removed or locked. I have seen it both ways and it is up to your jurisdiction on how to do that.

Secondly, you want to ensure that the suppression system is hooked into a monitored fire alarm system or on a direct dial alarm system.  We, the fire department, want to know if this system activates.  Even if the system puts the fire out, there is a possibility of fire being pulled into the vent duct. If there are any penetrations or gaps in that duct, fire could smolder above for a long time or it could be burning the uncleaned grease.  We also want to make sure that if that system activates it gets put back in service appropriately and prior to cooking commencing again.

In the video it shows a "dump" test where we make sure that the correct amount of product is being flowed and that all utilities are shut off with the activation.

I know this is not a tactical post, but it gives you a little insight of why these systems are important.  I may not have touched on all of the aspects of these systems, so if you have additional comments or suggestions, please feel free to comment.

Thanks, stay safe and be careful.

Who Takes the TIC?

In this age of the fire service, most jurisdictions have at least one thermal imaging camera, if not several. Ideally, we would like to have one on every apparatus.  But, of course, budgets and priorities will dictate how many each department feels they can afford and need.

What was once a tool advertised mainly to find victims in building fires, we have found many more uses for this piece of equipment.  It can be used for hazardous materials responses to identify product that may be producing heat.  It can be used to help find a lost person in open space outdoors.  We can use it to check for extension after a small stove fire or for chasing down fire in concealed spaces.

For as many uses as we can name, and I by no means named them all, there are multiple ways that they are deployed.  My preference is for the officer to come off of the truck or engine with the TIC.  Everyone has their own method of operation, but to me the officer makes the most sense.

The officer should be behind the nozzleman and should watching changing conditions at all times.  While doing this, it is easy for him to scan the room or area with the TIC to watch for heat currents, changes in temperatures or victims unseen because of smoke.  These again are not the only things that the officer needs to be doing.

So, the question that I am posing is “Who takes the TIC and how do you deploy it?”  What are your guidelines and how do you operate with it?

In addition, how does it get carried? Do you prefer a strap? Do you carry it in your hand?  Give everyone some input and ideas about what does and has worked for you.

What are some other uses not mentioned and offer some training ideas for the folks here?  Just remember, this is a tool and should  not take the place of masterful search techniques and hard work.

Stay safe and train like you work, hard.

Type V Construction-Wood Frame

1 comment

The next type of construction that we are going to talk about is Type V, or wood frame construction.  This is the most commonly used type of construction in most jurisdictions.  This type of construction is typically associated with residential occupancies, namely single-family dwellings, but many commercial buildings are now built using wood frame construction.

Years ago, wood frame meant real dimensional lumber. A 2×4 was really a two inch by four inch piece of wood.  Roof systems were stick built with rafters of dimensional lumber that were connected with a ridge beam.  We forget that this traditional type of construction is wood frame.  Balloon frame is also a type of wood frame.

We have just gotten so ingrained that wood frame mean light weight, or now commonly known as “low mass” construction.  This “low mass” construction uses engineered products that makes construction faster and cheaper to build. Although these components like engineered I-joists and roof truss systems are very strong for the engineered loads, they fail miserable during fire conditions.

We just need to remember the hazards and myths of this type of construction. One is that if one truss fails they all fail.  I like to ask the classes that I teach if any of them has seen a house constructed with wood truss systems with a part of the roof burnt off and the rest of it still intact?  The answer is always yes.

I am not saying that these truss systems are safe, quite the contrary. All I am saying is that we need to keep our firefighters educated about these systems. I know there are some chiefs and instructors upset with some of this, but we can operate on and under these roofs with some careful size-up and thoughtful tactics. One thing I have learned in the fire service; never use the words never or always.  There is always a circumstance or situation that will challenge both.

Now, characteristics about this type of construction.  There are void spaces everywhere and these components use a lot of glue to help keep them together.  These buildings are getting bigger on the residential side and this construction type is very popular for many commercial buildings like fast food joints, restaurants and strip malls.

Something we need to keep in mind also is that some of these wood frame buildings look like masonry or brick, or type 3 buildings.  These are just veneers and we need to understand the challenges dangers associated with that.  Masonry and brick veneers can easily collapse of the foundation and still kill or seriously injure firefighters.

Pay attention to your area and be familiar with the buildings you may have to operate in. Know the different characteristics of the construction types and the challenges each one poses for us operationally.

Train hard and stay safe.

Type IV Construction

2 comments

We are continuing to look at the different types of construction and the characteristics of each.  This post will outline considerations of Type IV or Heavy Timber construction.

Heavy timber construction is a type of construction we don’t see popping up in new buildings very often. However, there are still a great many buildings that are or were Type IV construction in our jurisdictions.  We need to identify these buildings in both circumstances.

True heavy timber construction does not have void spaces. It is built with masonry or brick exterior walls with large diameter, six inches and more, interior structural components.  There have been debates about how these large beams and structural elements hold up to fire and some have found the large diameter wood components to hold up longer than steel.  The reason for this is that the steel will elongate and deform at around 1000 degrees and is prone to failure at that point. The large diameter components may burn, but they hold their integrity longer than the time it takes for steel to deform.  Obviously, there are variables, but an interesting bit of information.

These fires burn hot and for a long time. These are typically large buildings and have an additionally large fire load, making extinguishment difficult.  Many times we find these buildings in more urban areas and in highly dense locals. However, churches and resort lodges are common places for this type of construction.  Exposure protection is of the utmost importance and establishing an effective collapse zone is important.

When these building get remodeled and are altered, they can then be considered Type III construction.  The reason for the Heavy Timber classification is the benefit of the extended time of burning and the lack of void spaces. We lose some of that as false ceilings and new framed walls and floors are added to create lofts or office space.  Just something to consider because you will need to plan accordingly for the interior changes that are being made to these types of buildings.

Train hard, master the basics and have plan before you go to battle. Stay safe.

Fire Service Books

2 comments

This is a little off the beaten path for me and my blogs, but it is something that I have been paying more attention to lately.  I have been laid up from a hernia repair and have been reading and doing a little research for other projects and it occurred to me that I utilize the same three books on a regular basis.

No matter what level you are at in the fire service, you should be building a decent sized library of fire/emergency related books.  This is one more method to staying sharp and on top of your game.  Having quality information to turn to for those forgotten tricks of the trade or to remember a characteristic of a certain type of construction is paramount and makes you a better firefighter.

Here are the three books that I use on a regular basis and why.

1. “Building Construction for the Fire Service,” 3rd Edition, by Francis L. Brannigan.

This book was one I got during the mid 90′s for a college course and I have it highlighted, marked and it is never too far from my grasp. The great thing about this book is that it has never gotten outdated.  The information is still relevant and insightful.  This is definitely one book that should be on your shelf.

Make sure you look at the “Tactical Considerations” in the chapters that give some ideas on how to apply the lessons to firefighting tactics.

2.  ”Collapse of Burning Buildings: A Guide to Fireground Safety,”  by Vincent Dunn

This book has a great deal of content that is covered in Brannigan’s book but more directly applied to the collapse of these buildings.  Chief Dunn goes into great detail how these buildings collapse and the problems that different types of collapses cause.

The illustrations are great examples for those that need some visual help and you can apply this information immediately as a firefighter and fire officer.  This book is a great tool to have company discussions with. Sit down with your crew and pick a chapter or topic and start playing out scenarios in your jurisdiction where these dangers exist.

3. “Safety and Survival on the Fireground,” by Vincent Dunn.

This book is everything firefighting.  Just about anything that you want to know about firefighting is in here. The great thing is that the information is short, to the point and easy to apply to situations.

Keeping these books and others within reach is a good way to stay engaged. These resources gives you valuable information at your fingertips when you need it. It is also a good way to pass on information to others and to have meaningful conversation about “fire stuff.”

Stay safe and keep your mind on the task at hand, becoming a better firefighter.

Type III Construction

No comments

Lately we have been discussing different types of construction. So far we have covered the characterisitics of Type I and Type II construction.  This is some really basic rookie school stuff, but it is so important to be able to identify these different building charaecteristics. We know that fire behavior is directly linked to the type of construction and the fuels invovled.  It also plays a major role in determining our tactics as company officers and firefighters on the fireground.

So, a quick review of what we have covered so far:

Type I or Fire Resistive is protected, non-combustible construction. Typcially steel and concrete with it’s structural components protected with fire resistant materials to meet or exceed two hour fire ratings.

Type II or Non Combustible is just that, non combustible construction. It’s structural components are not protected by fire resistive materials, but can be sprinklered.  These too are usually built with steel and concrete, similar to Type I construction but without the fire resistant protection.

On to Type III construction.  Type III construction is also referred to as Ordinary construction and is very common in a great deal of our older downtown areas.  It is not limited to those areas but this was the primary method of building during the early and middle part of the 20th century.

This type of construction is identified by masonry or brick exterior walls with wood joists and interior structural components.  Type III construction is very rarely protected with sprinklers and they have concealed spaces.  These buildings in many communities have been remodeled and altered due to the age and use of the building, so concealed spaces are a real concern.

During a fire the interior structural components are attacked and failure of these components can cause an exterior wall to fail at the same time.  The joists, for example, will rest in the masonry or brick wall and may be used to support the exterior walls. When these joists fail or burn out, they can compromise the support of the exterior wall it is connected to.

Here are some pictures that show some Type III construction.

Take a look at your area and determine where your different types of construction are. Discuss and plan for fires at those buldings and how you would operate at each one.  What are some different challenges each pose for you as a firefighter or company officer operationally?

Train hard and remember, master the basics.
