Corrugated Stainless Steel Tubing (CSST) - Know What You're Dealing With

Corrugated stainless steel tubing (CSST) is not a new product and has been installed in natural gas systems for quite some time. Although I have always been familiar with it, I've never specified it on project that I have designed. It's primarily used in residential construction and doesn't suit the commercial projects that I work on. I was not aware of any issues with this tubing from the engineering side and was surprised when I became aware of the hazards associated with CSST from the firefighting side.

Brothers Gone Too Soon

Sadly, I became aware of the issues with CSST following two LODD's. Both tragedies took place in a neighboring state and one of the lives lost was known by firefighters that I know from training and/or social media. If you are not familiar with the circumstances around their final calls, I encourage you to honor their memory by reading the reports and educating yourself. Their stories prompted me to do some research as a designer and as a firefighter. I was quite surprised at what I learned.

For those that are not familiar with CSST, it is a flexible, thin wall tubing used to distribute natural gas or propane typically in residential occupancies. Most people associate CSST with yellow, corrugated tubing because that is probably what is most commonly found. The shape and color of the tubing can vary based on the age of the tubing and whether it is meant for distribution or as an appliance connector. It is preferred because it typically results in less joints that can leak and is easier to install than more traditional steel piping. However, it can be damaged easier and is more susceptible to failure from contact with electricity which is a serious liability to firefighters.

Newer versions have a black coating and are provided with arc shielding. The coating does has a flame and smoke spread rating. Although the newest versions are ANSI and Lighting Code rated, there are concerns that the testing is not sufficient because the tested ratings do not reach a high enough current level to match what is experienced in common lighting strikes. This is what has caused the most recent LODD's.

It does seem to be relatively safe if it’s installed properly, but that's the problem. It's only as good as it was installed and it can be installed by the weekend warrior. There is a difference between distribution tubing and appliance connectors which may not be understood. They are not the same and not meant for the same application. There may be improvements to be made in its construction and some companies are proactive. Gastite has been improving its product over the years to make it safer and even tries to work with the fire service to make a safer product. 

The bottom line is that fire departments need to be educated. CSST is not flawless, but it's critical that the correct material is used and installed correctly. Some of the newer products are better, but still need to be improved. Firefighters need to beware of legacy installations as they will be less safe than newer installations and materials. Home owners should be encouraged to update older systems that aren’t as safe as newer systems. Local authorities having jurisdiction should mandate that installers submit certifications with permits to show that they are qualified to the latest standards and are installing the latest material technologies. Making sure that installations and the materials used are the best possible to ensure firefighter safety is crucial.

When to Detach from the Plan

In theory, our strategies and tactics for our incident action plan are developed based on our 360-degree size-up. In reality, our strategies and tactics of our incident action plan are developed based on many variables - the pre-incident size-up, the alarm size-up, the on-scene size-up and the post-incident (after action review) size-up. All these variables are covered in chapter 3 of my book, "The 5-Tool Firefighter" in greater detail. For purposes of this article, I am highlighting them for other purposes.

The pre-incident size-up

 The pre-incident size-up is the first and best place to begin putting our IAP together by collecting as much important and relevant information of the structure as we possibly can and therefore beginning to build our "gameplans" and try them out in training. During this size-up, we can locate and note the following:

  1. Construction type

  2. Interior space size

  3. Containment areas

  4. Stairwells and elevators

  5. FDC hookups

  6. Solar Panels

Note: variables change based on the type of construction and type of occupancy you are pre-planning. These six items are only a sample of what we could look to identify during a pre-planning.

The alarm size-up

During the alarm size-up this is where firefighters and fire officers should start considering the variables taken during the pre-incident size-up. On the way to the alarm, things to look into are as follows:

  1. Location of the structure

  2. Type of occupancy

  3. Current apparatus staffing

  4. Weather conditions and time of day (loosely)

  5. Apparatus placement (think water supply/aerial operations)

These areas will lead into building the strategies and tactics for our IAP for this particular alarm. Now comes the on-scene.

The on-scene size-up

This is where the pre-planning and alarm size-ups are put to work. All our work identifying key areas of consideration and training are now put to the test. In reality, it is where we are provided with much more information specific to the alarm, confirming our variables during the alarm size-up, such as building construction, type of occupancy and location.

 Here is where more in-depth size-ups will take place not only at the command level but at each company level. Firefighters of truck and engine companies will now begin going inside the structure and taking note of the area under a different light and different conditions and relaying their findings back to the incident commander. This information being done at the company level will now allow the IC (incident commander) to make fire ground decisions that’s are prioritized for a safe and efficient outcome. This process continues until command is terminated.

Post-incident size-up

Once we've returned to the station and cleared up, it is imperative that we begin to discuss what went right and wrong on the incident, no matter the severity of the incident. This helps firefighter and fire officers strive to improve on their strengths and weaknesses of their job and strive to be as successful as possible.

Things to consider:

  1. What did we expect to happen?

  2. What actually happened?

  3. What went well and why?

  4. What can we improve upon and how? 

Looking at these four areas of size-up, we need to understand one thing. Our incident action plan that is designed to assist is can also hurt us. Well, how is that possible? We have pre-planned, sized-up on alarms, trained on scenarios for this type of occupancy, we did everything? What would hurt us?

What could hurt us is by sticking to the script of the IAP. What do I mean by that? Unforeseen circumstances and confirmation bias.

The outcome of the incident is initiated in our thought process before we develop any strategies or tactics of the incident. In order to develop strategies and tactics we first must identify our outcome. Makes total sense right? We cannot plan for an outcome we do not have in mind.

Our confirmation bias also agrees but here is the caveat. We cannot identify areas of concern if we simply go off an incident action plan without detaching ourselves from the plan for a moment. Meaning, we use our IAP as a guide but also take the time to look around for key areas that we are predisposed to instantly ignore.

Here is an example. 

We prepare our alarm size-up and look at the time of day. For example, Engine 2 is responding to a fire alarm activation at 234 Sesame Street on a Tuesday at roughly 1400 hours. It is a 2-story residential wood frame structure and normally at this time the family is either working and/or at school. 

Initially we are thinking this could be a faulty smoke detector activation or maybe someone is home and it's burnt food on the stove. However, upon arrival we see no signs of "life" at the residence. There are no cars in the driveway or at the curb and no homeowner waiting for us. Right here, our confirmation has proven correct. No one is home and a faulty detector went off. 

We immediately considered that because of the time of day with no activity at home upon arrival and the lack of cars visible to us, it must appear no one is home. 

Now let's detach from that mindset for a moment. 

We automatically assumed based on the time of day and day of week no one would be home however, that simply cannot be the case. To overcome confirmation bias, we need to loosely take time of day into account and assume every response has occupants on scene. Having a rough idea of who might be home is good to have but it cannot be written in stone and here's why. 

A residential structure could with an attached or detached garage could have the homeowner’s car parked inside (off-day or working from home) or the car could be for all intents and purposes, at a shop getting work done.  

To go further into the example here is more details. The engine company officer decides to DETACH from the initial mindset and dispatch and peak around the exterior of the structure that has a 6-foot privacy fence around the side yard and into the backyard and notices black smoke coming from the basement windows on the "C" side (Charlie side ) of the structure after entering through the fence gate. 

We've identified two areas of concern here. One, we disregarded the confirmation bias of time of day that the potential of no one is home and we identified an unforeseen circumstance based on the initial dispatch of the alarm.  

By detaching from the plan for a moment and taking a step back to question and prove out your initial mindset can oftentimes be the difference between a reactive approach or a proactive approach. The IAP is a great tool to have although we must ensure we are always critically thinking on scene and not simply going through the motions.

Until next time - work hard, stay safe & live inspired.

The Importance of the 360 Size-Up

The importance of performing a 360 size up makes a huge difference in the operation of a structure. Keep in mind size up can be performed by simply walking around your first due area and checking out new construction. Let’s look at some simple factors I came across in a new residential community.

Picture #1

  • Two story wood frame single family home

  • Appears it could be balloon frame (although weird for new construction)

  • Only one door is in plain sight

  • Bottom window of the 1/2 corner is a bit raised appearing there may be a basement level or storage area below

Picture #2

  • House is actually a three story residential

  • Basement is designed to be fully furnished

  • Basement level could possibly be used as an apartment (could cause a hazard if the stairway between the basement and first floor is illegally blocked for privacy)

  • Two additional means of egress located off the first floor balcony on the #2 side and the basement level door

  • From the rear it’s clear it’s not balloon frame

Again, just a few small factors to hit on. Do you notice anything else?

Outside the Box 360

Performing a 360 upon arrival of a residential structure fire is crucial. Everyone always hits on building construction, type of occupancy, number of floors, and visible fire or smoke.

Did you notice a vehicle in the driveway, indicating someone may be home?

Did you see that the vehicle has a handicap placard on the license plate, indicating the owner may have a disability of some sort?

You walk up to the front door and notice children’s toys in the yard. Do kids live here?

Remember to look at the roof, utility lines connecting the house, solar panels, and satellite dishes. All these things could cause a hazard for crews operating on the scene.

You may arrive on scene and find a lot of clutter in the yard, leading to you assuming there may be hoarding conditions in the residence. We often find ourselves in tunnel vision and not looking at smaller aspects of the scene.

We want to hear from our followers. What are you looking for when you arrive on the scene?

Until next time - work hard, stay safe & live inspired.

Remembering the West Texas Fertilizer Plant Explosion

It was a typical spring evening with temperature s around 80 degrees on the evening of April 17, 2013 in central Texas. Humidity that evening was low with scattered clouds and 20 mile per hour winds blowing in from the south south east (SSE).

At around 7:30 that evening in the City of West, an explosion occurred at the West Fertilizer Company plant. An explosion so powered it registered as a 2.1 magnitude earthquake and felt over 80 miles away damaging many homes and school throughout the area. 

At this time, dispatched received a 911 call reporting smoke coming from the West Fertilizer Company plant and at 7:34 PM, the West Volunteer Fire Department was dispatched to the scene with two engines, a brush trick and tender responding to the scene along with two more firefighters arriving in their personal vehicles. The first arriving unit on scene was at approximately 7:39 PM confirming a structure fire at the plant and deployed an initial attack line (1 1/2 attack line) to extinguish any and all visible fire and to establish a water supply using a 4-inch diameter supply line. Please note, the nearest fire hydrant was more than a quarter mile away from the scene. An initial mutual aid alarm was struck with included an aerial ladder truck and four more firefighters which responded in their personal vehicles.  

Within 12 minutes of the initial arriving unit on scene and 22 minutes from the initial 911 dispatch, an explosion occurred at the plant leaving multiple firefighters down.

Ten first responders were killed in this explosion due to an estimated 40 to 60 tons of ammonium nitrate exploding just outside the city limits.

Five firefighters from the West Volunteer Fire Department were killed in the explosion along with four firefighters from 3 neighboring departments along with one off-duty career fire captain and two civilians who offered assistance to the fire department on scene. 

Factors of the incident

The department did not recognize the hazards associated with the ammonium nitrate

  • There was limited pre-planning of the facility

  • Rapid fire spread in wood construction commercial structure with no sprinkler system

Post incident recommendations as per NIOSH

Fire departments should conduct pre-incident planning of buildings within their jurisdiction to facilitate the development of safe fireground strategies and tactics especially in high hazard high risk structures

  • Fire departments should have a written management plan, use risk management principles at all structure fires and especially at incidents with high risk hazards

  • Fire departments should implement and enforce the Incident Management System (IMS) at all emergency operations

  • Fire departments should ensure all firefighters wear personal protective equipment appropriate for the assigned tasks

  • Fire departments should ensure all firefighters are training to the standards that meet or exceed NFPA 1001 Standard for Fire Fighter Professional Qualifications

 We remember:

Firefighter Morris Bridges

Firefighter Cody Dragoo

Firefighter Joseph Pustejovsky

Firefighter Douglas Snokhous

Benefits of Stretching

Unlike athletes firefighters and other first responders don't know when "game time" will be. It could be at 7am or it could be at 11pm but in any case we need to ensure we are at our best when the alarm goes off. As we know, we cannot predict when runs will come in and when they won't but preparation of our bodies before and during shift is just as equally as important as preparing our gear, tools and apparatus. Further, being able to wind down after runs is just as important as preparing for the shift and the potential call volume. This will help prepare the mind and body for work.

So where am I going with this?

I'm going with a focus on stretching. That's right. Stretching.

Stretching, even a short routine, added to your daily routine is a great benefit for overall health and wellness and pays off large dividends. It could be used as a pre-workout or a post-workout routine or both. Stretching can help unwind and release tension after a hectic day or even a long duration run as well as assist in increasing energy levels.

Here are some health benefits to stretching that help can keep you on the path for a long shift in the firehouse and overall better health.

1. Improves flexibility and agility which is important for all firefighters
2. Helps keep a decreased resting heart rate. A health heart is vital for all firefighters
3. Increases the circulation of blood and oxygen to the muscles
4. Helps remove waste from tissues such as lactic acid which is built up during intense exercise. Sometimes causing painful, sore muscles.
5. Helps prevent injuries
6. Increases overall mood and well-being.

Stretching at its best could be used a form of exercise for the body and mind. Keep in mind to only stretch as far as your current level of flexibility and over time the range of motion will gradually increase.

6 Stretches to do everyday to help improve flexibility, blood circulating, oxygen levels, relieve stress and tension. Do all 6, three times for 15-30 seconds each.

  1. Quadricep stretch

  2. Hamstring stretch

  3. Calf raise

  4. Spinal twist

  5. Kneeling hip-flexor

  6. Chest opener

Always remember, before beginning any type of exercise program to consult with your primary physician first.

Side note: As per the 2018 NFPA Journal on firefighter injuries, there was an estimated 58K plus injuries estimated in 2018 and also the lowest since the NFPA has been analyzing this data in 1981. In this report it was noted that the major type of injury during fire ground operations were strains and sprains, which accounted for 38% of all injuries while it accounted for 59% of all non-fire ground injuries.

Until next time; work hard, stay safe & live inspired.


The Engine Company Doorman

As we know each position on the engine company is an integral role to the success or failure of the job at hand. Each role is unique and plays an important part in the grand scheme. Like chess each firefighter is just as important as the other and how they're utilized is most important. In this case, it's the Door Man. A role that isn't spoken about much and like many departments today, is often times combined with the roles of back-up firefighter due to staffing limitations yet the responsibilities are crucial and play large parts during fires.
Here are some quick tips for the door man.

1. Back-up the hydrant firefighter. Ensure the cross-lay is emptied from the bed or assist with the static lay connection.
2. Know your hose estimates. Should the static lay be used, estimate the amount needed before connecting to the engine (better to go more than not enough)
3. If there is a back-up firefighter, assist in flaking out the line from the front to the back-up firefighter.
4. Prevent kinks in line. Choke doors as the line goes through.
5. Eyes on the structure. Monitor fire conditions at the doorway(s) and/or stairwell(s) and report any deteriorating conditions.
6. Next man up. Should the nozzle firefighter need to be relived, it's your job to step up.

There it is, quick tips for an often overlooked position on the fire ground however a role that plays dividends to the success of the fire suppression team.

Until next time; work hard, stay say & live inspired.

The Back Up Firefighter

As a firefighter riding in the engine we all want to be on the nozzle, fighting the fire head on, producing a solid fire attack to the fire and getting cheers from our fellow firefighters for a quick solid knock. However, not everyone can always be the nozzle man and get to be face to face with the fire. Sometimes we need to be the backup or the setup man if you will. It's not pretty or glorified but in this line of business someone has to do it and at one point in time many of us get that assignment. The assignments may be cumbersome but a solid, ready to fight backup firefighter is critical to a successful and aggressive interior fire attack.  

As the old saying goes, "the fire goes as the fire line goes" and without an experienced backup firefighter, the advancement, fire suppression and a long day at the office will prevail; not to mention a not too happy nozzle man. 

Here's a few tips every backup firefighter on the line should consider.

   1. Ensure there are no kinks in the line, especially the first 50 feet behind the nozzle. Kinks will be detrimental to a sufficient fire flow and delay hose advancement.
2. Hit the hydrant and establish a water supply to the engine. If there is a short crew, this may be the job of the backup firefighter. Ensure your hydrant skills are efficient and ready to go. Timing is everything.
3. Force the door. If the engine is first on scene, ensure the line is stretched and be prepared to possibly force the door if needed.
4. Search off the line. Perform a primary search if no truck company is in place yet. 
5. If needed, be the second or third set of eyes and ears for the nozzle man. Watch the fire's behavior and carefully monitor conditions in the room and update the nozzle man and officer if there's a sense conditions are deteriorating and a flashover and/or collapse is imminent.

If you're assigned as the backup firefighter get ready before the call comes in (physically/mentally)and ensure all PPE and equipment is ready to go. A successful fire attack is counting on it so get ready and stay ready.

Until next time; work hard, stay safe & live inspired.

You Have Just One Job

 "This shouldn't take too long." I'm not talking to anyone;that's just the thought in my head as I get ready to clean the bathroom today. On the first floor of my house there is a half bath that is just after the front door, on the right side. It's just close enough to the door that if you pull in to the parking space, Dukes of Hazzard style, and busted through the front door to use the bathroom, you can make it without an 'accident' happening. The bathroom needs cleaning. I go to work using an assortment of cleaners; being careful not to cause a hazardous environment needing 911. Now, it's time to mop. That is also the time things go in a new direction. I go to the hallway closet a few feet away on the other side of the hallway. I see a mop handle sticking up, but there is all this stuff in the way. I start cleaning the closet to get to the mop to clean the bathroom. I now have two bags of things to throw out, brooms and other floor cleaning devices neatly arranged, but no mop. A wide area search (of a townhouse, mind you) leads to finding the mop in another bathroom upstairs. To recap, I have cleaned the closet, to find and clean the mop, so I can finish cleaning the bathroom. But while cleaning the mop, I notice there may be a leak coming from the sink I used. So, after cleaning the closet to get the mop, I found and cleaned the mop, then found the leak, then cleaned up the water from the leak to clean the, uh…what was I supposed to be doing again?

At that moment, I see myself in a place I have been before. Perhaps you have found yourself in that same place. I have one thing on my mind to do. In the process of working on that one thing, I accomplish 3 or 4 other things. Never what I set out to do in the first place. Once I realize the situation I am in, it was easy to tell I didn’t use my focus habit.What habit do I use to keep my focus? The yellow sticky note habit.

People who have worked with me have seen and made fun of my yellow sticky note habit. I admit, it's definitely a little odd. I can't remember how I got started using it, but I've done if for a while. I take two 3-inch yellow sticky notes and stick them together back to back so the sticky parts are at opposite ends. Now I have a 3-inch paper that I can write on both sides. On only one side of the note, I write the date and everything I want to try accomplish that day. The rest of the day, the list resides in my pocket. Periodically for the rest of the day, I look at my list and see what I have done, and what I still need to do. Whatever I don't finish, goes on the list for the next day.

Time has taught me that the size of that paper doesn't allow me to put more on it than I can finish in one day. I stay focused, keep track of my progress, and I can evaluate if what I'm doing is more important that what is on my list. I use this at the station, at the office, and sometimes at home. I get laughs about my list at the station, at the office, and sometimes at home. I find that I am more efficient and productive at the station, at the office, and sometimes, at home.

My habit for staying focused may not be for you. It doesn't have to be. We all, however, need some way to keep focused on our intended tasks. Completing tasks, completes objectives. Completing objectives, completes goals. And completing goals is how ordinary people have extraordinary impact.
