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.

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

Remembering the Hackensack Ford Fire

On July 1, 1988, when firefighters of the Hackensack Fire Department arrived on scene of the Ford dealership on River Street in Hackensack, NJ around 3pm, they did not know how deceptive the fire would prove to be. They did not know that five of their fellow firefighters would not be coming home. On the initial alarm, Hackensack firefighters on two engines, one ladder and chief car responded to a reported fire at the Hackensack Ford auto dealership. During fire operations, fire was discovered to be burning above in the truss over the service area and was vented by the truck company on scene. Fire suppression was attempted by both engine companies through two ceiling hatches above the service area. Shortly thereafter, an evacuation order was transmitted over the radio of which were not acknowledged by any of the units working on scene.

Otherwise known as the Hackensack Ford Fire, this fire claimed the lives of five firefighters battling a fire in a bowstring-truss building when the roof suddenly collapsed. Three of the five firefighters lost their lives in the middle of the service area of the dealership. The other two firefighters became trapped in the rear storage room and were unable to be rescued. After approximately 1 hour into the operation, these five firefighter lost their lives and were the first line of duty deaths in the department's 117 year history to that point.

Remember & Honor

Capt. Richard L. Williams (Engine Co. No. 304)

Lt. Richard R. Reinhagen (Engine Co. No. 302)

Firefighter William Krejsa (Engine Co. No. 301)

Firefighter Leonard Radumski (Engine Co. No. 302)

Firefighter Stephen Ennis (Engine Co. No. 308).

34 years later this fire has had significant impact on today's fire service. This fire is one of the most analyzed LODD events in the history of the fire service. Numerous issues were noted from the incident including a breakdown in communications. The findings and observations of this fire are still valid today.

The lessons of this fire has resonated deeply within the fire service across the country. The Hackensack Ford Fire caused the fire service to begin looking at building construction on a more serious level especially when operation in and around truss construction and having the ability to identify construction types and truss. It also highlighted a weak command structure, insufficient and ineffective radio communications along with a lack of portable radios for firefighters and a lack of manpower. These lesson stay true to this day.

In an article published the day after the tragedy, Fire Chief Anthony Aiellos said, “There are only 100 of us in this department, and this is just a small place. In a town like this, these are your friends. These were good men.”

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.


Solar Panels: A New Addition to Today’s Fire Service Enemy

In a 24 hour period the sun produces enough energy to supply our planet for over four years. That’s 1,460 days of solar energy the planet received in just 24 hours. Solar energy is everywhere and the advancements in it are growing and for many reasons. It's renewable, pollution free and cuts costs of other energy sources. What's this mean for firefighters? Well it means a lot. Solar panels are popping up all over buildings and on plots of land like never before. We're noticing this by a simple placard found on the commercial structures that are now using solar energy with the letters "PV" on it. 

 “PV" which stands for photovoltaic is the method of converting solar energy into direct current electricity (DC) using semiconducting materials that exhibit the "photovoltaic effect". The "P" which stands for photo (light) and the "V" which stands for voltaic (electricity), this of which it bears its name. The PV effect is the creation of voltage or electric current in a material when exposed to light. 

In today's society, solar panels are everywhere just like truss construction is everywhere. Thus creating a need for firefighters to be aware of the dangers and understand how to attack fires with PV systems. 

For firefighters to be safe and operate efficiently on the fireground, there are a few critical steps we must take to ensure the solar panels are accounted for and in check. Do not begin fire suppression until these first 2 steps have been completed.

  • 360 Size-up: This is a no-brainer. By performing a 360 size-up upon arrival, firefighters are able to possibly locate the panels or the energy storage system (ESS) if the panels are on the roof or an area without access to at the time. Most of the time depending on jurisdictional building codes, the ESS panels are located on the exterior of the structure normally near the utilities, the garage or the basement, should the structure have one.

  • Treat this as an electrical fire and turn off the systems starting with the utility grid. The main breaker box will activate the backup battery and run the risk of electrical shock to interior firefighters in the structure. If the battery is located in a confined space in the structure and exposed to heat above 150 degrees Fahrenheit, it is imperative that ventilation of that space begins.

Once the size-up has taken place with the panels and/or ESS located along with fire suppression taking place, ventilations needs to begin. However, firefighters and command need to understand that if the panels are located on the roof and are burning, there is a potential for collapse based on the volume of fire around the panels and on the roof. 

 When performing ventilation, especially vertical ventilation, firefighters must recognize that electricity is being produced by the panels 24 hours a day. 

  • Once these steps have taken place, fire suppression can now continue. As a safety precaution, firefighters should try and extinguish the fire at a minimum of 20 feet away when using a straight stream or a minimum of 5 feet when using a fog pattern.

  • After the fire has been knocked, overhaul can begin - carefully.

Panel safety

Firefighters should be careful not to touch any of the panels in case of any damage done to them during the fire. Instead, firefighters should cover the panels with canvas tarps, especially at night due to no sunlight exposure to them. The reason panels should be covered during night operations is due to the wires running through the conduit to the charge controller or inverter which continues providing the panels power. 

Battery safety

If the battery was the source of the fire, continual water flow to the extinguished battery is important to keep the battery cool and from the possibility of obtaining a chemical reaction causing a thermal runaway. Should a thermal runaway occur, the temperature inside the battery will reach the point that causes a chemical reaction inside the battery. This reaction produces more heat and drives the temperature of the battery higher, causing further chemical reactions and more heat. In thermal runaway, the battery cell temperature will rise in milliseconds and release suddenly. The chain reaction will reach temperatures of around 752 degrees Fahrenheit and produce gassing of the battery along with fire. 

Burns tests have shown that lithium-ion batteries can produce these chemical reactions 72 hours after extinguishment. 

 As technology changes, firefighters need to be educated and trained on all of the new advancements in the market today. By doing so, firefighters can continue to develop a proactive approach to new technology when responding to incidents. Solar panels may not be completely new to us but the growth of them in residential and commercial structures has rapidly increased over the years. Today, it is nearly impossible to not catch a glimpse of solar panels on almost every street across the country. Stay diligent to the advancements in the world and continue to keep training and getting after it.

 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.

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.
