2012 Telsa Motors Model S Electric Car

1 comment

Tesla Motors is a Silicon Valley-based company that designs, manufactures and sells electric vehicles (EVs) and electric vehicle powertrain components. If you used PayPal before the company was bought by eBay than you helped this car company get off the ground running. Elon Musk, a cofounder of Telsa Motors was also a cofounder of PayPal and Space Exploration Technologies Corp. (SpaceX). As of July 2010, Tesla had produced more than 1,200 Roadsters sold in at least 28 countries. The Telsa Roadster retails around $110,000! However, Telsa Motors wanted to offer an all electric 4-door sedan with a smaller price tag, the Model S. The Models S has a base price of $49,000 with the $7500 tax credit subtracted (Good marketing). While the Model S is not for sale to the public yet, test vehicles are out on the roads now. 

Notice the wheel well and the C-Pillar all integrated into one piece?

The battery pack is thin, low, and is under the entire passenger compartment.

No comments

The 2009 to 2011 Peugeot 3008 Body Structure is a well built vehicle.  The 3008 is a crossover with a reinforced structure to protect its occupants with its rigid body.  Notice the reinforcements in the front door?

Reinforced Body Structure

Collapsible Impact Absorber

With the introduction of the Boge impact absorber (Peugeot’s words, not my) which uses two conical absorbers located between the impact absorption beam and the chassis leg, this “collapses” with controlled deformation in the event of a collision.

6 Airbags

Peugeot 3008 has 6 smart safety airbags deploy to protect the occupants.

  • 2 front airbags, protect the front passengers
  • 2 side airbags are located at the back of the seat and in the side trim
  • 2 curtain airbags work in conjunction with the wide airbags

One of my goals this year is to get to 2011 likes on the BoronExtrication.com page on Facebook.  Hitting this number would be a major milestone, since I’m only at 149 as of right now.  However, with your help, we can get there. So I have to ask, do you like it?

Electric Vehicle Safety Training Project PDF Files

No comments

The Electric Vehicle Safety Training project of the National Fire Protection Association has two very informative reports in pdf format.

U.S. National Electric Vehicle Safety Standards Summit report (pdf)

The National Fire Protection Association (NFPA) and the SAE International have released a summary report from the co-hosted U.S. National Electric Vehicle Safety Standards Summit held in October that focused on how current codes and standards address safety and electrical infrastructure concerns related to electric vehicles. The summary report prepared by the Fire Protection Research Foundation, an affiliate of NFPA, focuses on fundamental codes and standards issues as they pertain to electric vehicles in the areas of:  vehicles; built infrastructure; and emergency responders. 

 

 

 

Fire Fighter Safety and Emergency Response for Electric Drive and Hybrid Electric Vehicles (pdf)

As the use of alternative energy proliferates, the fire service has identified a number of areas of concern with hazard mitigation and emergency response. This includes electric and hybrid electric vehicles, which are introducing new and unexpected hazards to fire fighters and other emergency responders.

The goal of this report is to assemble and disseminate best practice information for fire fighters and fireground incident commanders to assist in their decision making process for handling electric and hybrid electric vehicles. Specifically, this study focuses on vehicles intended for roadway passenger use involving fire and/or rescue emergency situations, either on the roadway or at charging/docking stations (e.g., garages). The project deliverables will be in the form of a written report, which will include best practices that can serve as the basis for training program development by others.

The deliverables for this project collectively review the available baseline information, identify the fundamental principles and key details involving fire/rescue tactics and strategy, provide a summary of core basics, and address and clarify related issues such as training needs, areas needing further research, revisions to codes/standards, and other applicable topics.

A companion study to this report focuses on solar power systems rather than electric and hybrid electric vehicles (Fire Fighter Safety and Emergency Response for Solar Power Systems, FPRF). This has taken an identical approach and focuses on assembling and disseminating best practice information for fire fighters and fireground incident commanders to assist in their decision making process. This companion report addresses buildings and other structures with solar power systems that are intended to supply power to the respective structure, with a primary focus on solar photovoltaic panels used for electric power generation.

This overall initiative (consisting of the reports on Electric Drive and Hybrid Electric Vehicles and Solar Power Systems) is funded through a U.S. Department of Homeland Security (DHS) Federal Emergency Management Agency (FEMA) Assistance to Firefighters Grant (AFG).

The Final Stop on the Chevrolet Volt Training

No comments

First off, my hat off the fine folks at GM, OnStar, and The National Fire Protection Association (NFPA) for setting up and implementing a nationwide training program of First Responders on the new technologies in the Chevrolet Volt.   This week is the final stop on a nationwide tour where more than 1,600 fire and emergency service leaders have been trained.  Fitting the last stop is where it all started, Detroit!   The training was held in the OnStar garage at General Motors headquarters in downtown Detroit.  Chevrolet and OnStar, in a joint effort with the NFPA expect 400 Detroit-area first responders to be trained in learning how to deal with emergency situations involving electric vehicles in Detroit, Michigan this week.

The NFPA’s Electric Vehicle Safety Training project is a nationwide program to help firefighters and other first responders prepare for the growing number of electric vehicles on the road in the United States. The NFPA project, funded by a $4.4 million grant from the U.S. Department of Energy, provides first responders with information they need to most effectively deal with potential emergency situations involving electric vehicles.

The NFPA is behind the Electric Vehicle Safety Training project Blog and check out the post about GM passes the torch to NFPA on EV Training.

2010 Porsche 911 GT2 Body Structure

No comments

The body structure of the 2008-2010 Porsche 911 GT2 (aka Porsche 997)  has some major reinforcements in the roof rails, just look at the green running from the top of the A-Pillar to the C-Pillar.  The monocoque structure, lightweight, hot-galvanized all-steel body shell with the front lid and doors made of aluminum.  Just in case you were wondering what a monocoque structure is; it is a construction technique that supports structural load by using an object’s exterior. In a vehicles the sheet metal skin supports the interior structure.  In others words, it just a fancy word for a Uni-body vehicle.

2011 Mini Cooper Body Structure

The Mini Cooper was brought to the United States by BMW.  The US introduction in 2001 of the First generation Mini Cooper (2001-2006) had two models,  a 3-door hatchback and a 2-door convertible.  The second generation Mini Cooper  (2007 – present) has grown to several different models that include a 3-door hatchback, 5-door estate, 2-door convertible, and a 5-door SUV.

2007 to Present Mini Coopers

The Mini Cooper is made from a bunch of different steels.  High-strength steel, tailored rolled blanks, aluminum door elements, and a magnesium carrier bar for the dashboard between the A-pillars.  So if this car catches fire, be prepared for the 4th of July light show when you hit the passenger compartment with a fire stream.  The door reinforcements are diagonally arranged and an aluminum extrusion-pressed. You can see this in the body structure image in the posting.  The Generation 2 body structure is ultra-rigid and more advanced than the first generation.

  • Two roof-mounted side-curtain airbags for front and rear seat passengers

2011 Porsche Cayman Body Structure

1 comment

The 2011 Porsche Cayman Body Structure is shown below, not that there are a ton of these on the road.  However, cutting up a car that cost more than the average house has got to be a rush!  The metals shown in green are Ultra-High Strength Steel (UHSS) while the pink or magenta are parts formed from Tailored blanks.  This means the thickness can vary throughout the entire part because Tailored blanks are made from several different blanks of varying thicknesses that are laser welded together.  If I lost you, (which I almost lost myself in that last sentence) than check out my posting about Tailored Blanks.

Nissan LEAF Emergency Response Guide (ERG)

1 comment

Nissan has published an Emergency Response Guide for the 2011 Nissan LEAF for First Responders.  The is filled with 30 pages of information that is well, not firefighter friendly in my opinion.  I like to see color diagrams and lots of pictures.  However, it’s an Emergency Response Guide on a new vehicle with new technologies so I’m thankful Nissan took the time and cost to put one out.  One important procedure is the high voltage system.

Nissan recommends using the electrically operated parking brake and wheel chocks to stabilize the vehicle. There’s only one catch, you have to set the brake before you secure the 12V system.  Just to add another little step to apply the brake, you need to “firmly” apply the brake pedal then pull up on the electric parking brake switch located on the center console.  Too many steps in my book.  So if you are thinking like me and what to chock, block, and blow the tires (gently that is).  Just make you follow the proper placement of cribbing as shown below.  Nissan does not want you to crib under the battery which is basically the entire floor pan.

LAFD Fire Captain Knocked Unconscious Following Blast

4 comments

Engine 1 of the  Los Angeles Fire Department found a 2000 Chevy Impala fully involved on arrival and attacked with a 1-and-a-half-inch line but had problems containing it.  A Captain on scene was knocked unconscious following a blast after he observed fire in the passenger compartment and attacked the fire with the attack line.  Take a look at the pictures and story at Firehouse.com and read the official LAFD Report about the incident.  A little off topic in terms of extrication, but the story stills involves a vehicle!  Let me know what you think caused it.  Here’s a quote for the report to get your brain thinking:

As the firefighters were establishing the second line, the Captain observed fire in the passenger compartment in the vicinity of the steering column and attacked the fire with the initial fire attack line in order to prevent re-ignition of the fuel. The fire around the steering column displayed unusual burning characteristic of combustible metals (small white hot appearance, similar to a sparkler). The quick application of water to extinguish the fire around the steering column caused a violent reaction/explosion. The violent reaction/explosion forced the Captain backwards.

That makes me lean toward a certain metal that is cast and used to reinforce the instrument panel.  What do you think?

2011 Cadillac SRX Body Structure Identification

No comments

The 2011 Cadillac SRX Body Structure has a wide range of different Ultra-High Strength Steel (UHSS) to consider during an extrication.  Just remember that so many different factors come into play when cutting UHSS so never think that you are outgunned!  Have a Plan A, Plan B, etc!

2011 Cadillac SRX Body Structure Identification Extrication

The B-Pillar (item 10) is a combined mixture of different UHSS.  The outer B-Pillar is martensitic and the inner reinforcements are Dual Phase Steel and other UHSS.  The Side Door Impact Beams (item 13) and Rocker Panel (item 14) are made with UHSS.

service B-Pillar

Cadillac Service B-Pillar

The collision repair guide on the 2010-2011 Cadillac SRX states that the B-Pillar can only be replaced as a one piece, no sectioning!  The service B-Pillar will come as a complete assembly and the center B-Pillar Reinforcement is constructed of ultra high strength steel (martensitic).   Ultra High Strength Steel normally has a tensile strength greater than 700 MPa.

Here’s a little interesting note I ran across from GM, when GM calls out UHSS this classification includes common steel names of Martensitic Steel (MS), Press hardened Steel (PHS), and Boron Steel.

Inner Reinforcements of the B-Pillar

The Inner reinforcements of the B-Pillar are seen in the image to the right with the rocker panel and outer B-Pillar removed.  Remember the reinforcements are UHSS Dual Phase.  General Motors states that Ultra High Strength Dual Phase Steel (Dual Phase Steel with a tensile strength greater than 800 MPa), also known as DPX cannot be repaired.

Technical Assistance, a blog by an enthusiastic firefighter

1 comment

One of the coolest things about the Internet is how it crosses all borders and languages.  With a quick click of a icon, you can translate a site into almost any language. I was emailed a link to an extrication blog in Germany early this morning by Jörg Heck from Moditech Rescue Solutions.  Moditech developed the Crash Recovery System (CRS) for emergency responders.  Crash Recovery System is a revolutionary tool that I’ll cover in the next day or two.  Anyway, back to the  blog from Germany. I was able to take a look around it this evening and it is worth adding it to your bookmark list!  The blog is called Technical Assistance by  enthusiastic firefighter named Patrick Allinger.  Patrick’s view on learning and educating people is what I think and the main reason I started this blog.  Here’s a little info about Patrick.

With this site I now try to pass on my past experience and my knowledge built up in various seminars to other interested colleagues, but also even to learn new things and learn.

If I’m just not go on the Internet or spend my free time at the fire department, I put in the middle of my studies in industrial engineering from the Cooperative State University Stuttgart, which I’m doing with my business partner Weber hydraulics.

Give Patrick’s blog a look and let me know what you think.

 Technical Assistance Blog Patrick Allinger

 

Patrick understands what the fire service is all about, sharing knowledge.  Captain Liam J Flaherty of FDNY’s Rescue 2 said it best in the film “Brotherhood”.  I may not have his quote totally correct, but he said something like the job of senior firefighters are to pass down their knowledge to younger, newer firefighters.  He then follows it up with “if their not, their not doing their job”.   In Patrick’s case, you have a young firefighter passing on his knowledge while keeping his mind open to learn more.  My chief always says, the day you walk into the firehouse thinking you know it all is the day you should quit.

2011 Toyota iQ and Scion iQ Body Structure and Airbags

4 comments

Scion is a Toyota brand and the Scion iQ is based off the Toyota iQ, so consider them one in the same. The 2011 Toyota iQ and Scion iQ is a tiny car that is packed with Ultra-High Strength Steel. However, the thing that scares me about this car are the nine, count them, 9 airbags. That means 9 cylinders stuffed into hidden areas of the body structure behind the trim panels.

The rear air bag is ejected from the headliner during a fender bender. Toyota says it will help protect the heads and necks back seat passengers. So there is a good chance that the rear air bag will be deployed by the time that first responders arrive. Just remember to always strip away the trim to find the gas filled cylinders. Ron Moore posted on the University of Extrication forum that “inflators now have a stored gas pressure of up to 10,000psi”. Take the time to find the cylinders or at least make sure your cutting thru one. As cars like the iQ hit the market, airbag cylinders are going to show up more often.

I was looking around for a image of the inflators and I ran into an article by Dave Dalrymple that he wrote for Fire Engineering, New Vehicle Technology and New Extrication Challenges.

The curtain’s inflation module is inside the air bag itself and located in the rear roof edge between the rear head rests. As for the rest of the nine systems, count them from the crash recovery system diagram (photo 8). So it’s not just high-end vehicles that have a wide spectrum of SRS systems. Although this vehicle is not yet for sale, look for it in 2010, possibly as the Scion IQ.
