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,

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.

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.

We hear it all of the time in the fire service and many of us agree; we don’t spend enough time training and learning building construction and fire behavior. So, in the spirit of practicing what I preach, here is a short lesson on Type I construction, or otherwise referred to Fire Resistive construction.

This first picture shows all non-combustible structural components of an addition to our local hospital. This is the basement, but the floor above is of similar design with interior wall studs of metal.

The floor above is concrete on metal decking, which you can see in this first picture.

You have a steel column, a steel beam with metal bar joists as the primary structural components with the exterior walls all of concrete.

As I mentioned before, the floor above is the same with the exception of the exterior walls being non-combustible metal stud walls.

Here is the same area from a different angle with a fire resistive coating sprayed on the structural members.

[View with PicLens]

The data cable that you see is plenum rated and is for the computer and communications networking inside the facility.

In addition to the spray coating, the entire facility is fully sprinklered and has a monitored alarm.

The spray coating is designed to be applied to a specific thickness depending on the rating that is being achieved. Normally, and in this instance, a third party inspector is present to randomly inspect the thickness and provides a report to the building commissioner and the fire marshal.

What characteristics of this type of construction are important when sizing up a building like this?

What are some tactical importances in regards to operating at this building or one of Type I construction?

If you have any experiences or suggestions to add, please post them.

Stay safe and train hard,

I am a big fan of companies getting out and scoping out their response area. Just when you think you have seen it all, something catches your eye that you missed the other 100 times you passed it by.  We all know what I am talking about.

Look at the picture above. As a fire service leader, what do you see?  What have you learned from your years of experience and training about these types of buildings?

What is of significance?

What is of significance that you see right away but the new guy might not have a clue about?

As an officer that will be making the initial decisions on this building you have a great responsibility to know as much about this structure as you can.  It will certainly help you to make the best possible decision about your tactics.

Take the time to sit with your crews and look at the features of this building. What type of construction is it?  What type of occupancy is it?  Why are both so important?  It just might mean the difference of saving the occupants and yourself.

Stay safe and be careful.

Residential or commercial?

Even in this downturn in the economy, there are still very large homes being built.  In many cases these homes are over 5,000 square feet of total living area.

This creates a significant problem for many fire departments, especially smaller, more rural ones, in regards to tactics.

We are fighting these fires with traditional methods and resources. In many cases it just isn’t enough.  Add to the those issues that these are all built using light-weight construction, we have a recipe for disaster, as we have seen across our country.

Firefighters are falling through floors immediately after entering.  Roofs are collapsing much earlier than before.  Contents are causing fires to burn faster and reach untenable temperatures much earlier in the fire.  The larger area requires the firefighters to search longer and further into a building than in the past.

We need to look at these structures a little differently when confronted with a working fire in them.  Here are some considerations that should not be overlooked on these fires:

1. Your going to need more water, get it rolling fast.

2. A 360 is a must. You don’t know what you might have on the back side. 4 stories, victims hanging out windows, location of the fire, etc.

3. A larger line. It may be very prudent to pull a 2 1/2 as your first line of attack.

4. More manpower may be needed due to the multiple functions needed because of the size.  You may treat this alarm like a commercial alarm.

5. Search lines. In these very large homes, it is not out of the question to use a search line.

These are the primary items that you can’t discount. You may need to think differently on these larger home fires to have a positive outcome. I have seen departments burn these houses down because they were using tactics for an 1100 square foot building on a 5500 square foot house.

With the open floor plans and the light weight building materials, fire develops very fast in these homes. Anticipate that and plan for it. Adjust and have back up plans.  Never be afraid to regroup to get it right.

Feel free to add to the concerns, I encourage you to contribute. After all, that is what makes this so much fun.

Stay safe and stay low. Don’t forget to hydrate all day in this heat. Carry around some water and sip on it all day.

What do you see that makes you say, Hmmmm?

Take a look at this picture and tell me what you see?

It isn’t the operations, necessarily, that I want you to see here.

This is why the officer/s need to be aware and not get tunnel vision.

Too many times I have seen new and veteran officers take the nozzle from the back stepper and go barreling in without any regard for what is going on around him.  His days on the nozzle are over for the most part. His job now is to see the conditions and to take a look at the big picture.

So, what do you see?

Stay safe and be careful out there.

With the fire service and others taking this day and weekend to remember the Charleston 9, along with other high profile LODD, I wanted to do something different. I wanted to look at how we can specifically apply the recommendations that were listed in the report on the Charleston Super Sofa Fire.

I am going to do this just one at a time and I will likely take several weeks to cover them all.  It is very likely that some will intermingle with others, and will be covered together.

Today I want to look at pre-incident planning.  For me, this starts with when the building is being built.   In reality, it is a combination of both, during construction and visits and regular intervals.

conduct pre-incident planning inspections of buildings within their jurisdictions to facilitate development of safe fireground strategies and tactics

Light weight, engineered floor joists.

Today, we stopped in on a new restaurant.  As you can see from the photo it is all light weight, engineered construction.

The comment was made that we need not enter this building if it burns.  Well, in an ideal world that is correct.

The fact is is that we just don’t know what we will be tasked with doing if this building catches fire.  We can’t predict what time of day or who will or will not be in it.  What we can do, however, is know what this building is made of and the hazards associated with those materials and products of construction.

We also must be prudent in our tactics when arriving, like lifting ceiling tiles before we get too far in the building, looking for fire running above us.

This visit provided some great information aside from the type of construction and those hazards associated with them.  First, the building is completely sprinklered.  That is a plus.  We located the FDC and the nearest hydrant.  Both good things.

Concealed spaces over the booths.

We found that this concealed space had sprinklers dropped down to the ceiling level, but none were in the space or immediately above it.  An easy place for fire to spread quickly.

As we discussed earlier in the post, most would say we don’t need to enter this building.  In theory I agree, but we never know what we are facing when we arrive.

Something that we learned was that there is an area on the east side of this building, Side D, that is built with dimensional lumber and is sprinklered as well. The roof construction is not truss and the walls are all dimensional studs.  What can we take away from this?

Side D construction was different than the rest of the building.

We discussed that if there needed to be an attempt to make entry, it would be best to try to take a stand from this area. It is not part of the rest of the roof system and will likely hold up a little longer with the dimensional lumber.

Another idea was that RIT would be staged near this entrance if there would happen to be interior crews making a rescue or knocking down what was perceived as a small fire.  They know that there is a straight shot to the middle of the building through a more secure type of construction.

With all that being said, accessibility to the building needs to be looked at; where will multiple units be staged?  Where will you place ladders and are there overhead dangers?

It is important to look at all of these factors to make a good decision based on prior knowledge.  We also understand that Plan A doesn’t always work so have a Plan B ready based on the planning you did on the building.

There are many other components about pre-incident planning that I didn’t mention, but hopefully you get the point.  Get out and visit these sites.  Be involved and have discussions about how you would perform at a fire here.

Above all, don’t let the lives lost at any LODD be lives lost in vain.  Learn from their mistakes, but don’t be critical, we have all screwed up and been lucky enough to get away with it.  Be constructive and train on the recommendations so that you don’t repeat history.

Stay safe and please, never forget those lost in the line of duty.  We owe them our promise to train hard and to learn from them.

If you pulled up on this store front or one like it, what is your first course of action?

With a fire or just a haze, one of the first things that needs to be done, with an attack line ready, is to start looking above the drop ceiling.  Even if it is drywall, you have to see what is above you in these occupancies.

These types of occupancies are found in fast food establishments, sit down restaurants and strip mall type buildings.  Most of these new commercial buildings are all light weight, truss, engineered lumber construction.

By lifting the tiles and breaching the ceiling, we know how far the fire has advanced before committing people into these buildings.  The concealed spaces are important for initial fire attack in these situations.  It might indicate that the front door is as far as you go.

You have to consider, however, that the overhang outside the front door could be compromised if fire is found in the void spaces of the ceiling.  Fire could be racing through the soffit of the overhang out front.  Additional weight of signs will also cause early failure of these building features.

Remember to think on your feet and be sound in your decisions.  These decisions come from experience and training.  So, train hard and often.

Stay safe and be careful.

Light weight construction is everywhere.

This is a picture of some light weight trusses being set on a commercial building.

As you look at this building you can see that it seems to be a series of stores or spaces in a commercial building. Most likely a strip mall type building.

In the old days, these were block buildings with steel roof components, structurally speaking.  They were fairly sturdy buildings, still not great, but heavier construction.

Now, it is all light weight wood.  No doubt they will put a facade on this building that looks like rock or brick, but it is a house of commercial occupancies.  It is also easy to see how fast a fire in the concealed space will consume those truss members, causing very early failure.

In addition, remember what goes on top of these buildings; HVAC units.

Just be aware of what is in your area. Stop by and look at these buildings.  Make sure they are properly building fire barriers and walls with penetrations fire stopped.

Use your training and common sense when these buildings burn, they are dangerous in today’s fire service.

Take care and stay safe.
