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.

Food Trucks and Firefighting Concerns

For decades food trucks and food carts have been service food to people on street corners, carnivals and events all around the world. In today's world, food trucks and food carts are popping up everywhere. From birthday parties to school and work functions you name it and a food truck is probably there serving food. These carts or trucks are known as Mobile Food Preparation Vehicles or MFPV for short. Some are trucks designed to house a kitchen setup and others are trailers pulled by a truck or SUV. Either way both serve the same purpose, preparing food for customers.

 

These trucks provide a unique set of challenges for firefighters and provide a few hazards that commonly scene when fighting vehicle fires.

 

We are very well aware that cooking is the leading cause of accidental fires in the United States with respect to residential fires. With respect to commercial occupancies, these structures are more well equipped to handle the potential of an accidental mishap in the kitchen. Commercial kitchens mitigate the risk through hood suppression systems over their cooking appliances such as ovens, burners and grills. The same goes for MFPVs…but not exactly.

 

The newly designed, custom-built food trucks will be equipped with hood suppressions systems however the older retro-converted trucks may not be as equipped. Making the workers not as fortunate should an accidental kitchen fire breakout. In all cases, all MFPVs will be equipped with portable fire extinguishers to suppress kitchen fires from grease, fat and cooking oils.

 Propane Tanks

The most significant risk of fires to MFPVs are propane tanks. According to the NFPA, 68% of food truck fires are related to leaks or failures in the propane tanks themselves. Propane is used in various ways with respect to food trucks. For one, they're used as fuel for cooking and possibly refrigeration.

 

While propane is generally safe to cook with, a small 20-pound cylinder on a backyard grill has the explosive equivalent to 170 sticks of dynamite. MFPVs can carry around 100-pounds of propane cylinders at a time in order to be efficient and produce food services to customers. One hundred pounds of propane is capable of producing more than 2.6 million BTUs (British Thermal Units). One food truck carrying that amount of propane can generate 6 times more energy from an exploding propane tank than a backyard grill using a 20-pound propane tank.

 

Since these trucks are constantly moving from place to place, the risk of a propane failure can increase. This is due to the trucks driving on bumpy terrain or hitting potholes. Both of which can loosen the connections and fittings or cause structural damage to the tank. With respect to air, propane is heavier. In fact, propane is 1.55 times heavier than air which causes it to sink. Thus, causing a pooling effect near the floor should a tank leak. Because of this, a single spark from the cooking appliances has the potential to ignite the gas.

 

Many trucks carry spare tanks or have their current tank fitted to the outside of their MFPV which decreases the risk of leaks inside the unit. The risk this does carry is tank explosions from minor collisions on the roadway or single vehicle accidents.

 Generators

Older MFPVs are more likely to pose a risk with the use of portable generators. These are used to run electricity to the truck. Older MFPV's or converted ones could possibly lack the proper ventilation of the off gases from the generators which raise the risk of carbon monoxide emergencies in the mobile unit. 

 Past Incident

On July 1, 2014, in the Feltonville neighborhood of Philadelphia, a leaking propane tank ignited and exploded. The truck operator and her daughter were severely burned and died three weeks later. An additional 10 others were injured as a result of the blast.

 

Since then, the NFPA has made changes to NFPA 1 and NFPA 96. The leaders at the NFPA concluded that an easily adopted national standard would go a long way in increasing the number of communities with comprehensive food truck safety regulations.

 

These standards and changes can be found at the links below:

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.

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.

Blank Slate

This past year my wife and I were blessed to welcome the birth of our first child. For those who are parents know the thoughts that go through your mind; joy, excitement, nervousness, and worry just to name a few. The last 7 months have been the most amazing and important yet difficult time we’ve ever experienced.

Each day we watch our son grow, learn and take on life. He learns a little more and more about himself and us each day and us the same about him. The one thing I’ve noticed as he discovers life and becomes his own little person is his impressionable innocence. Everything he’s exposed to and everything he’s taught is absorbed like a sponge.

The same is true for those entering the fire service. New recruits come in as an empty slate who, for the most part don't know anyone or how anything works and will absorb everything they hear, see and read like a sponge. In order to keep the fire service family and brotherhood alive, it is upon us, the current generation to do our best to not allow any negative emotions or feelings towards a fellow firefighter and departmental policies be absorbed by the newer generations coming in. The best thing we could do is to look at the things we don't agree with and turn it into a positive remembering why we signed up for this job. Just like babies, new recruits are excited and have an eagerness to learn, grow and a hunger to prove themselves worthy of this job. So let's embrace the newer generations entering the fire service and show them that although there is downsides to what we do, we can always walk in with a smile on our face,  have an eagerness to learn and a willingness to always pay it forward with the hopes of developing the generations to come.

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