Take a quick look at the 2013 Porsche Cayenne Body Structure. Notice what appears to be a box where the driver’s seat would be installed? That is the battery box for the 12V battery. Just like the VW Touareg. The screenshot from Moditech’s Crash Recovery System (CRS) clearly shows the 12V battery underneath the driver seat.

Quick Review. Below is a quick overview of the 2013 Ford Fusion and Lincoln MKZ Hybrid and Fusion Energi. The emergency response procedures for the Fusion Hybrid, MKZ Hybrid and Fusion Energi vehicles are similar to those for traditional gasoline-powered vehicles with the addition of special considerations for the high-voltage electric system components.
The Fusion Hybrid, MKZ Hybrid and Fusion Energi vehicles use a conventional gasoline
engine in addition to an electric motor to power the vehicle.
- Gasoline is stored in a traditional fuel tank.
- Electricity is stored in a high-voltage battery pack.
For additional information review the 2013 Fusion MKZ Hybrid Emergency Response Guide.

The automotive industry has changed the way first responders approach a motor vehicle accident compared to a decade ago. Air bags are standard equipment, pretensioners are used in second and third row seats, and the seats are starting to resemble a firefighter jet seat with the technology packed into a small package. Situational Awareness is the new catch phrase in the extrication world. First responders must be aware of hazards of a vehicle from bumper to bumper!
For years extrication trainers preached peel away the plastic interior trim to ensure an air bag gas inflator is not in the cut path. However, those days are long gone! What we need to start doing is a quick “trauma assessment” if you will on our vehicles before we make a cut to any pillar or roof structure. Once the interior trim is pulled off palpate any visible nylon air bag curtains close to the metal. Deployed gas inflators statistically do not pose a safety hazard if cut. However, the best stance to take is to never cut through a gas inflator because there is no method available to us to determine if the inflator is still charged.
Occupant sensors in the front seats are devices that measure the distance away from the steering wheel or dash and weigh the occupant to determine if the air bag should be deployed in a crash. Have you ever put your backpack on the passenger seat and notice that the “Air bag Off” light turns on? This is an example of the sensor weighing the load on the seat and determining that the occupant in the seat does not meet the minimum weight for the air bag to deploy in a crash.
Pretensioners
Seatbelt pretensioners tighten the belt a few inches to prevent the occupant from jerking forward in a crash. Pretensioners are mounted in two different methods, to the seat belt retractor located in a body pillar or on the seat structure. Front seat mounted pretensioners are typically mounted to the top of the seat adjustment track. Seat mounted pretensioners will moved the seatbelt buckle and not the seatbelt. A center console usually provides enough protection for first responders not to have to worry about any hazards from charged pretensioners.
Buckle mounted pretensioners uses gas stored in the tube to retract the buckle during certain crashes. Retractor mounted pretensioners like the TRW one in is set off by any electronically fired pyrotechnic charge which retracts the seatbelt by 80mm, which is more than three inches. During the earlier stages of a crash, the pretensioner removes excess slack in the seatbelt to begin effective occupant restraint.
Pretensioners are not reserved for front seat passengers. Many late vehicles like the Volvo have pretensioners in the rear seats. Pyrotechnic pretensioners in the rear seats can be buckle or retractor mounted. Many rear seats that are split into 60/40 seats have a metal tower that is thick and big that holds a high mounted seat belt retractor. This tower is located in the 60% seat or the larger of the two. If the seats are split up into 40/20/40 than the tower is located in the center or 20% seat.
Some vehicles have a pre-collision safety system that includes an electric motor-pyrotechnic pretensioner system. During a pre-collision event like extreme sudden hard braking, an electric motor in the pretensioners retracts the front seatbelts. Once the event stabilizes the electric motor will reverse itself. The pyrotechnic pretensioners function normally and separately from a motor-pyrotechnic pretensioner system.
Load limiting is a safety that is used to minimize belt-inflicted injuries. A basic load limiting feature is sewn into the belt webbing and stitches are designed to break when a certain load is applied to the belt. The belt extends when the stitches come apart and allow the sewn webbing to unfold. A mechanical load limiting device use
Air bags
Air bags entered the automotive market as an air bag in the driver’s steering wheel. In 2011 model year vehicles, 10 different air bags in per vehicle are no longer a feature reserved for expense luxury vehicles. Automakers proudly advertise air bags on the vehicle interior on the steering wheel, bash panel, and pillar trim panels.
Seat Air bags
Seat mounted air bags are not a new hazard facing first responders. The difference is in the size and numbers of air bags packaged in a
seat are changing. Front seats can have two separate air bags to protect the occupant during a crash. This number is expected to increase when centered mounted seat air bags are used. Seat air bag are located along the outside of seat back frame and the bag is stored in a deflector called a “Taco” that directs the air bag when deployed.
Center Mounted Seat Air bag
General Motors has developed a front center air bag deploys from the right side of the driver’s seat and positions itself between the front row seats near the center of the vehicle. The tubular tethered air bag is designed to act as an energy absorbing cushion between driver and front passenger in side crashes. The air bag will also be deployed during a rollover. The center mounted seat air bag will be in the Buick Enclave, GMC Acadia, and Chevrolet Traverse starting in the 2013 model year. Toyota developed a rear center console with an air bag that deploys between the rear passenger seats. Toyota has not put this air bag into production yet, but it is likely to make into a vehicle platform soon.
Side Air bags
Occupant ejection mitigation is new safety requirement that the automakers must meet by 2017. Side air bags and glazing of side window glass are the methods being tested and engineered into current model vehicles. These air bags will be large volume that can run from A-pillar to D-pillar. The 2011 Grand Caravan has a side impact air bag over nine feet long and is inflated by a stored gas inflator the size of a child’s lunchbox thermos and has over 10,000psi!

2011 Dodge Caravan Side Air bag
Knee Air bags
Knee air bags are typically located underneath the steering wheel on the angled portion of the instrument panel. The knee air bag module is a rectangle box easily package as a complete air bag systems with the gas inflator inside. This helps during installation at the auto plants and allows this system to be used in different vehicles.
Door Air bags
Many luxury auto makers have started installing door air bags. The air bags are typically installed in the center of the door.
Airbelts
The 2011 Ford Explorer was the first production vehicle to have inflatable rear seat belts. Ford plans to offer inflatable seat belt technology in vehicles globally in the future. What is important to remember is the airbelt requires a stored gas inflator store in the seat. A pioneering company, Moditech, provides current information on hazards inside and outside the vehicle. Moditech developed the Crash Recovery System (CRS) and the image below of the 2011 Ford Explorer.
Key Fobs
Keyless ignition is nothing new but many automakers are offering the features on their vehicles. Hyundai offers keyless ignition with a key fob or smart key that works on proximity. So how do you turn the car off if there is no key in the ignition? Most vehicles have a “Start” or “Power” button that is used to switch the ignition from off, to on, or to ACC. Make sure you the button indicator light is off. If you see a “READY-ON” light on the display the vehicle is started. This is very important with hybrid or electric vehicles because of the quiet operation. An important note, on some vehicles the “Power” button indicator light turns off when the vehicle is started. That is why it is important to make sure you do not see “READY-ON”!
Batteries
First responders are aware of hybrid and plug-in electric batteries inside of the passenger compartment. However, 12-volt batteries can also be found inside of the passenger compartment. For example, the GMC Acadia has the 12-volt battery located in the floor behind the front passenger seat.
Is that vehicle totaled?
Late model vehicles have dozens of safety systems that keep occupants safe during a crash or rollover. Just because the vehicle may look repairable does not necessarily mean it is. Plastic interior trim panels and seat covers are designed to rip or tear when air bags deploys. Seat structures are engineered to distribute the load of an occupant. Seatbelts can have rip stitching to absorb energy from the occupant. Pyrotechnic pretensioners are onetime use. Keep in mind that most of the time in a serious accident the glass is already broken out and the windshield typically has spider marks from the air bags or occupants. Never let the fear of “totaling” a vehicle compromise patient care. Just remember all the hazards mentioned in this article are real and in vehicles.
Did you ever think you would encounter the Flux Capacitor from the movie Back to the Future at an MVA? Do you need to look out for 1.21 gigawatts? Believe it or not, the Flux Capacitor was an ultra-capacitor. Though the Variable Torque Motors (VTM) ultracapacitors aren’t made to hold the massive 1.21 gigawatts of the DeLorean in the movie.
The VTM Hybrid is designed for all types of Class 3 though 7 vehicles including shuttle buses, refuse trucks, delivery vans and school buses. The VTM Hybrid is the most affordable hybrid solution on the market. How the system works is it automatically adds torque ahead of the engine to boost acceleration and then conserving energy normally lost in the braking process. What is very interesting is the system is 500 pounds lighter than alternative hybrid systems because instead of batteries it uses ultracapacitors to store energy. Yes good old ultracapacitors!
Variable Torque Motors ERG
Emergency shutoff switches are clearly marked and easily located (including one at the driver’s side) in case of an accident or for maintenance safety. These switches isolate the ultra-capacitors to ensure that no power can be discharged to the vehicle and simultaneously inform emergency responders that the vehicle is a hybrid, which can change their response tactics.
You get dispatched to a cable company van that is upside down on the highway. Did you ever think it could be a CNG vehicle? While At&t has deployed over 5000 Alternative-fuel vehicles deployed including 3,469 CNG vehicles and 1,617 hybrid electric vehicles, as part of a $565 million commitment to deploy approximately 15,000 alternative-fuel vehicles (AFVs) over a 10-year period through 2018. So what do you know about CNG vehicles?
Here’s a list of guides that are availble:
- CNG Instructor’s Guide from Todd Hoffman from Scene of The Accident
- Honda Emergency Response Guide CNG Civic GX
- Alberta Vehicle Extrication Association (AVEA) Links
- Cal Fire State Fire Marshal Presention
- Emergency approach procedures for five of the most common types of alternative-fueled vehicles (AFV)

2012 Chevrolet Express Cargo Van (1200 vehicles)
The delivery of 1,200 Chevrolet Express compressed natural gas (CNG) dedicated cargo vans will be deployed to AT&T service centers nationwide. So chances are, you may have one roaming the roads near you!
So how are all those trucks going to get fuel? In Michigan, DTE Energy Company unveiled a public fueling station on 44th Street SW for vehicles operating on compressed natural gas (CNG). DTE has 20 natural gas stations in Michigan and sells the compressed natural gas to other companies like AT&T for use in its fleets of trucks. Keep an eye out and know what’s in your response area!
The NFPA just released a Emergency Field Guide for sale. The price is modest at $45 for a print copy. I like to see extrication field guides hitting the market. There’s a pocket electric/ hybrid guide getting ready to be released soon. A lot of rescuers still like to have a printed copy in their hands to flip through. Hopefully, I can get a copy yo review and provide a complete review. In the mean time, here’s what the NFPA has to say about it.

Body Structure
Avalon’s body structure is strengthened to help meet the latest side impact standards, accounting for higher-riding vehicles such as SUVs. In the event of collision, reinforced members, pillars, panels and doors absorb impact energy, then distribute it around and away from the passenger cabin for enhanced impact protection.
Airbags
Avalon’s Dual-stage Front Airbags are designed to deploy with the most appropriate amount of force – lower and less forceful in the event of a moderate collision; higher energy level for more severe impacts. Front Seat-mounted Side Airbags, built into the seat and not the door pillar for enhanced protection, have been designed to provide a greater coverage area. In addition, standard front and rear Side-curtain Airbags help provide protection for all passengers in side impacts. Avalon also features a driver’s knee airbag as standard equipment.
Notice where the side airbag inflator is located?
Just like the 2012 Buick LaCrosse, the 2013 Chevrolet Malibu Eco shares the same hybrid style system.
Buick Emergency Response Guides:
The Chevrolet Malibu Eco vehicles are front-wheel drive, five passenger vehicles with a lightly electrified gasoline engine. The eAssist system utilizes a high voltage battery, located in the trunk, as a supplemental power source. The system assists the engine utilizing a high torque belt-driven starter / generator.
The eAssist system features a 130 volt lithium-ion battery, which provides electrical energy to the starter / generator. The high voltage battery assembly is located in the trunk behind the rear passenger seats. The assembly includes several internal components that operate together to provide and control the high voltage for the eAssist system.
There are two separate electrical systems within the eAssist vehicles: low voltage (12 V) and high voltage (130 V). The low voltage system is similar to a conventional vehicle.
Do NOT cut the:
- Roof rails near the center pillar; contains side curtain airbag inflators
- Front seat back on the outboard edge; contains side airbags
- Center pillar near the rocker; contains the seat belt retractor pretensioner and side impact sensor
The Chevrolet Malibu Eco is designed to protect the occupants during a collision. The body structure contains high strength steel; this is highlighted in blue. The occupants are protected from front, rear, and side impacts by a structural cage created by the underlying vehicle structural design. Additional crumple zones protect the occupant with front, side, and rear rails that are designed to crush in a crash.
Cut through the low voltage cables on each side of the yellow labels to remove a section of the cable to ensure the cables cannot inadvertently reconnect.
Make sure you read thru the Emergency Response Guides below:
What’s different about the Veolster compared to a typical vehicle?
One design technique automakers use is common parts that can be used in different places in the vehicle, but are the exact same part. Another commonly used technique is design a part that is symmetrically opposite, or in better words, a mirror image. This is the reason most side airbags and inflators are generally located in the same location from driver side to passenger side. However, that is not always the case. Take a look at the body structure of the 2012 Hyundai Veolster. Not only are the side airbag inflators in a different location on the driver compared to the passenger side. The B-Pillar is completely different from driver to passenger. Now on the Hyundai Veolster, a quick inner survey should reveal that the passenger side has a rear door. Always keep in made the vehicle could be pinned up next to a jersey barrier or another vehicle that could hide features of the vehicle. While the 2012 Hyundai Veolster is a uniquely designed body structure and definitely not typical. We need to add the body structure design and asymmetrically airbag location into our mental toolboxes!
My trip started off at the Fremont Fire Department Administrative offices for some classroom training. The picture of the hydrant below was a gift from the Recruit Class of 01-1 in appreciation for the time, knowledge and training given. Something I thought was really cool!
I have said this many times on this site. Ron Moore is one fire service instructor you need to see in person whenever you get the chance. Ron has a passion for extrication and informing firefighters with useful knowledge to stay up to date with the continuous changes in vehicle technology. Wednesday was a full day in the classroom where Ron covered airbags, hybrids and electric vehicles, and the advanced steels in vehicle body structures.
Here is a question Ron asked during the airbag portion of class. What is the maximum number of airbags possible in a vehicle? What’s your answer? 9, 12, 15, 25 or infinity. There is no easy answer! Seatbelt airbags, center mounted seat airbags, door airbags, and the list goes on and on! Also remember that the “airbag” advertisement on plastic trim and seats is just that, an advertisement. The location of the airbag and or gas inflator has no direct relation to the advertisement.

The lead instructor, Brock Archer, arranged for a BMW ActiveE electric vehicle to be displayed after lunch for everyone to review and look at. I have a bunch of the pictures of the BMW ActiveE on the Boron Extrication Facebook Page. Make sure you check the images out and if you don’t already like our Facebook page, please do!
Stay tuned for parts 2 and 3 of the West Coast Extrication trip! Part 2 will be on school bus extrication and Part 3 on advanced extrication techniques.
BoronExtrication.com’s first post flying high over the central United States. Heading out to Fremont California for a train the trainer extrication class that Brock Archer is holding at the Fremont Fire Department Training Center. Brock Archer is the former Assistant Fire Chief for the Hopland Fire District. He is a California State Fire Training instructor and teaches swift water and rope rescue at the NFPA level. Brock is currently teaches auto extrication throughout the U.S. which is why I’m headed west! I missed the first two days of the class but with Ron Moore flying in tonight to teach a full day tomorrow then two solid days of practical extrication training to finish up the class. Every firefighter needs to see Ron Moore at a live presentation. Ron is one the best fire service instructors because he gears his topic to areas that are important and relevant to firefighters operating on an extrication scene.
I also plan to stop by a few firehouses in the San Francisco/ Oakland area. I really would like to meet the firefighters behind Axehead Clothing and Wolfpack Leather Works. Both of those guys are Oakland Firefighters I believe. 

The current Toyota FJ Cruiser (2007-present) has some very large roof airbag gas inflator. Take a look at the images below and let me know what you think. The size of the roof airbag inflators makes me what to reach out to some friends at Toyota and get so information on the volume and PSI on the inflators. Stay tuned!
The screenshot below is from Moditech’s Crash Recovery System. If you haven’t liked Moditech’s Facebook Page you are missing out on some great information that they post on there! Make sure you like the Boron Extrication Facebook page too!
Hopefully by now, no one is intimidated by electric or hybrid vehicles. Once the High Voltage (HV) battery is disconnected all you have is a vehicle that has a really big battery in it. However, learning how to safely disconnect the HV battery by pulling out the service disconnect plug requires one key of information, where is it? The service disconnect plug can be located inside a console, the trunk, or even hidden under the carpet. The Nissan Leaf’s service disconnect is located under the carpet behind the center console.
The Emergency Response Guide (ERG) for the Nissan Leaf provides step by step instructions on how to find and safely use the service plug to disconnect the HV battery. In black and white that is. Take a look at the ERG instructions below and see if you think you can figure it out. A special thanks to Eric J. Rickenbach from Rescuetechs.com for the photos!
MiEV is an acronym for Mitsubishi innovative Electric Vehicle and it is a five-door hatchback electric car and is the electric version of the Mitsubishi i. There is not an Emergency Response Guide (ERG) for the North America version yet because the 2012 model is the first year sold in the United States. The information below is taken from the European market, well the Germany ERG for the 2011 Mitsubishi MiEV. The US version will have some changes, but expect most of the vehicle to remain unchanged. Check back, I’ll post info on the 2012 US model as soon as it is available.
More Mitsubishi rescue data sheet/rescue maps are located here.
With just over 4000 Chevrolet Volts sold in the United States the Michigan made electric cars are started to be exported to other markets. The European market will have the choice of the Volt or the Opel/Vauxhall Ampera. The Opel Ampera is the European version of the Volt. The main differences between the Volt and the Ampera are in the styling. The Ampera will have one additional drive mode than the Volt, City Mode. The “City Mode” adapts battery management to the needs of commuter travelers which engages the range-extender engine (or “gas generator”) immediately. The Amperas will be branded as a Vauxhall in the UK.Australia, Brazil, and Japan will have limited numbers of Amperas/Volts imported.
For our knowledge the hazards in the Volt and Amperas are the same in all the models. The basic vehicle platform is the same regardless of the country. However, just remember, the Volt is just a car. If you know how to disable the HV battery than it’s just a car with a huge battery in it! The information below was taken from the Chevrolet Rescue Data Sheet for the European Union markets.


The emergency Response Guides (ERG) that the auto makers are getting more detailed and starting to include extrication recommendations. The 2012 Toyota Prius ERG contains a recommended process to remove the roof when the side airbags are not deployed. A total roof removal is not recommended when the side airbags are not deployed. Toyota provides an image in the ERG to show where you should cut the roof. The roof center section inboard of the roof rails should be cut from front to rear. Make sure you remove all glass including all windows to ensure all broken glass is controlled and the patient is protected. Toyota states that the area highlighted inside of the roof rails in from store gas inflators and other hazards, but also peel away the trim panels to verify for yourself.
Cutting inside of the roof rails is a quick effective way to get access to the patient. A fast cutting method is to use a metal cutting circular saw. The Prius V has an optional transparent dark gray polycarbonate roof panel. Now I have never cut a polycarbonate roof panel, but its’ just a glorified piece of plastic so a metal cutting saw should work fine. One important note about using a metal cutting circular saw, once you start your cut watch for the pressure from the pillars pushing the roof rails toward the center of the vehicle. If you don’t follow me, let me switch materials. Imagine you are cutting a piece of plywood and halfway thru the saw blade gets stuck.
The solar panel generates a nominal 60 watts of electricity but does not produce high voltage. The maximum output possible is 27 volts and maximum current of 3.6 Amps. This is under optimal conditions.
Voltage is generated when the solar panel is exposed to sunlight the output wire maybe energized even after the vehicle is shut off and the 12 volt auxiliary battery is disconnected. Current will only flow if the solar ventilation blower fan circuit is turned on.
The solar panel is located on the roof above the rear passenger space above. The solar panel output wire is not electrically connected to the 12 volt auxiliary battery, SRS airbags, or the High Voltage battery pack. The solar panel output will not back feed power to these circuits.
Breaking or cutting the solar panel is generally not a hazard except for injury that may occur from material fragments.
The Solar Panel Ventilation System only powers the fan but the Remote Air Conditioning System activates the A/C compressor is powered by the high voltage system. This is important to remember. However, the Remote Air Conditioning System only operates for 3 minutes and then the high voltage battery cables are de-energized because the high voltage flow from the HV battery pack stops.
