The After Action Review: Post-Incident Size-Up

The size-up is for all intents and purposes, our game plan or battle plan, if you will, against the structure we are working at. The size-up is where firefighters and fire officers gather information in order to make safe, efficient, and effective fire ground decisions. Fire ground decision making, as we know, is meant to be quick, but with an emphasis on safety and ensuring the tactics are done efficiently and effectively.

One aspect we do not stress enough is the fact we do not consider the culmination of the incident. After fire command is terminated and all units are back in quarters and in service. We must remember the pre-planning is not over just because we cleared the incident and everyone is back in the station and safe. This is where the add-value work is put into place and now it is time for the after-action review or post-incident size-up.

During the after-action review (AAR), firefighters and fire officers can discuss and share information obtained from the alarm and also discuss the success and failures they have experienced during the alarm. This is a time to ask a few question:

• What did we expect to happen?

• What actually occurred?

• What went well and why?

• What can we improve upon and how?

The benefit of asking these questions allow for strengths to be easily identifiable making it easier to uncover areas of weakness. By uncovering areas of weakness, you can develop ways to improve them! If you do not identify what went wrong, how could you ever expect to improve? On the contrary, if you do not understand what went right and why, duplicating that same success in the future will not be easy. Ensure necessary changes discussed in the AAR are implemented sooner than later as the longer it is on hold, the greater the likelihood of any changes being implemented diminish.

The size-up as a whole is a valuable step by step process for all firefighters, to obtain knowledge of their response district, riding assignments, and strategy and tactic implementation. By beginning this process formally or informally early on, it will allow for continual growth for each firefighter and fire officer. The key to success as an individual and team is to get ahead of the game and prevent ourselves from being reactive, rather proactive.

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

 

Electric Vehicle Fire Considerations for Second Due Company Response

Due to the nature and potential duration of a fire involving an electric vehicle, the second due company, whether it be a rescue or squad company play a vital role in the strategies and tactics of fire suppression operations.

Here are a few considerations for second due companies in response to an electric car fire.

  • Upon arrival and not completed, establish a delineated Hot Zone and ensure all personnel are in full PPE and donned with their SCBA and on air.

  • Consider ventilation. The buildup of vapors from an EV are potentially toxic, flammable and explosive. If deemed safe, the second due engine should consider and attempt to open two doors of the vehicle to allow and prevent buildup of vapors.

  • Attempt to shut down the high voltage system of the EV, if it is not already on fire.

  • Provide access for the suppression team to the location of the battery in order for water to be applied directly on it. This will help cool the battery and prevent thermal runaway.

  • Ways to open the vehicle for access to the battery depending its location

    • Remove the doors and rear seat top

    • Open and remove the trunk lid

    • Tilt the vehicle for access to the floor batteries. Consider using air bags, spreaders and cribbing, a comealong or winch to do so.

The main purpose of the second due company for electric vehicle fires is to provide safety for all personnel on scene and work in obtaining access to the EV battery location to help prevent further thermal runaway. Since cooling these batteries could take up to 30 minutes or more, it is vital there is a dedicated company on scene working to identifying and gaining access to this crucial piece of the vehicle.

Key Terms

High Voltage

For automotive applications, any voltage greater than 30 volts alternating current, or AC, or 60 volts direct current, or DC, is considered to be a high or hazardous voltage due to the potential to produce serious injury or death due to electric shock. Electric drive systems on commercial vehicles can operate at voltages as high as 800 volts, both AC and DC, and can produce peak currents as high as 100 amps, which make contact with high voltage components even more dangerous.

High Voltage Cables

Visible orange cables are another indication that a vehicle has a high voltage system. That is because there is a voluntary Society of Automotive Engineers, or SAE, recommended practice that specifies that all high voltage cables have an orange outer covering. While voluntary, this practice has been adopted by virtually all manufacturers.

Electric Vehicle Fire Considerations for the First Due Engine Company

Automotive technological advancements have evolved drastically over the years. Modern amenities of connectivity are found is every new car being brought onto the market today. Social media apps, real time traffic and weather updates to cameras not just for backing up but also for covering multiple blind spot areas of the car. Although the biggest advancement and great challenge for firefighters is in the invention of electric vehicles (EV).

Firefighters must be aware of the dangers of these vehicles and have steps in place when responding to vehicle fires involving electric vehicles. For purposes of this article, we are going to outline steps to take when responding to an electric vehicle fire as the first arriving engine company.

Secure a Water Supply

As any well-trained engine company, the first thing that must happen is to secure a water supply immediately upon arrival. This is a crucial step in a meaningful knock on the fire. When compared to an internal combustion vehicle (gas fueled), an electric vehicle can take up to ten times the amount of water to cool or extinguish.

Let's think about this. An internal combustion vehicle would normally take 500-1000 gallons of water to cool or extinguish while an EV would take a minimum of 10,0000 gallons of water alone to extinguish or cool the battery. Reports have shown that it has taken 30,000 - 40,000 gallons of water to do such fire suppression on EVs. 

Up to 150 000 liters of water needed to put out a fire in an electric car | CTIF - International Association of Fire Services for Safer Citizens through Skilled Firefighters

Once a water supply is established, the next best option is to treat this like a motor vehicle extrication and if possible, stabilize the car and initiate any victim removes if required. The silent movement of these vehicles could cause them to roll and cause for other hazards putting firefighters at higher risks of injuries from the moving vehicle.

Handline Selection

Due to the naturae of these vehicles and the amount of water needed to either cool or extinguish the fire, it is best to either stretch a 2 1/2-inch handline or if staffing permits, pull multiple 1 3/4-inch handlines. As suppression team(s) approach the  vehicle, it is important to utilize the reach of the straight stream of the nozzle and to take note of the reaction the vehicle is having with the water. The initial application of water may cause a flare up of fire due to the combustibles within the EV.

Locate the Battery

Upon extinguishment of the main body of fire, it is imperative that firefighters quickly locate and identify the location of the battery, and this is important for monitoring signs of thermal runaway using a thermal imaging camera (TIC), including: 

  • Identify the heat signature present

  • Vapors escaping from the battery pack

  • Listen for popping sounds from the battery pack

  • Locating visible fire around the battery pack 

*Note, the thermal runaway temperature for lithium-ion batteries is approximately 176 degrees Fahrenheit or 80 degrees Celsius. Beyond this, the risk of chemical reactions leading to thermal runaway increases drastically. The maximum temperature during thermal runaway can reach greater than 300 degrees Celsius or 572 degrees Fahrenheit.

If any of these signs are identified, the battery pack should begin to be cooled and performed in such manner: 

  • The stream from the hose line should be directed to one area on the battery pack and applied for 3 to 5 minutes

  • After the 3 to 5 minutes, firefighters should assess the battery again for thermal runaway and the items listed above.

  • Should the signs of thermal runaway still be presentable or have seemed to be found on a new area of the battery, the stream should be again applied for another 3 to 5 minutes, followed by another assessment of the battery pack.

  • This process should be repeated until the pack is no longer showing any elevated temperatures.

Monitor the Battery 

After fire suppression team(s) have cooled the or extinguished the battery and all hot spots on the battery have cooled, it is best for an engine company to remain in place with an established water supply still in place for at least 30 minutes before the EV is moved from the hot zone.

Key definitions to take note of:

Thermal Runaway

Thermal runaway occurs when a lithium-ion battery becomes overheated and is often triggered by overcharging, a short circuit or other cell stress. A chain reaction in the cell that generates gas is triggered by excess heat. This can spread to the rest of the battery pack if not mitigated, which can cause other cells to overheat and then decompose. The runaway causes the release of flammable gasses as it takes hold and the battery cells break down. 

Lithium-ion Battery

A lithium-ion (Li-ion) battery is an advanced battery technology that uses lithium ions as a key component of its electrochemistry. During a discharge cycle, lithium atoms in the anode are ionized and separated from their electrons. The lithium-ions move from the anode and pass through the electrolyte until they reach the cathode, where they recombine with their electrons and electrically neutralize.

 As the fire service studies and investigates the complexity of electric vehicles fires, it is imperative that we continue to remain diligent when responding to EV fires and keeping up with the everlasting changes of how to approach and attack fires involving electric vehicles.

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

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?

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.

Re-Present Yourself to Represent Your Department

From the time we enter the academy to the time we are sworn in as firefighters, we are training to become a better version of ourselves. Even after we graduate and begin our time as a firefighter we are still training each and every day to improve ourselves to become a better version of ourselves but what about the department and community we serve? They say the name on the helmet represents the department and the name on the jacket represents who raised you. Well, what if the name on the helmet and the name on the jacket are not only being represented by you but your “re-presenting” those names through you? 

Think about that for a minute. The 2 names on your uniform are being “re-presenting” through you. The town, the communities and other agencies know the department on the helmet and may quiet possibly know the name on the jacket but it’s how the names are carried and “re-presented” that makes the difference. It’s easy to put the uniform on and go to work but it’s another thing to put the uniform on and go to work with humility, honor and respect. Ask yourself these questions when you’re “re-presenting” the names because this is how you are “re-presenting” your department and your name to others.

1. Am I respectful to my boss and my crew?

2. Am I humble?

3. Do I respect the job?

4. How do I want these names to be “re-presented” to my fellow firefighters and the community?

5. Am I training hard each and every day to improve myself mentality and physically?

6. Would I be able to lead myself?

Being a firefighter and wearing the uniform isn’t a right, it’s a privilege. A privilege many people wish they had and a privilege that can be taken away at any moment. Be conscious of how you act and speak when wearing any part of that uniform on and off duty, it’s showing how you present yourself and also how you are “re-presenting” the names on that uniform. So do a service to your department, the community you sworn to protect, your fellow firefighters who ride alongside you, your family and most importantly yourself and “re-present” them the way you would want someone to “re-present” you. 

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