  • Las Vegas shootout blows up taxi

    http://abcnews.go.com/US/las-vegas-s...ry?id=18556451
    for video, local radio says it was a 'propane' taxi.

    It looks like the CV was T-boned. Was it CNG? If so it's the first CNG related death in decades.

      ....Six other vehicles were involved in the crash that followed, including the taxi and Maserati.
      The taxi was affiliated with Desert Cab company, according to general manager Sandy Shaver.
      The driver and rear passenger were dead at the scene.
      Shaver said he was called to the scene to provide information but did not know the identity of the victims.
      Shaver said it was possible, but highly unlikely, that the vehicle was being driven by someone other than a Desert Cab driver.
      Shaver also said the taxi that was struck was not fueled by propane or natural gas, as some had speculated.
      Gillespie said the cab exploded from the "sheer force" of the impact of the crash.

        my thoughts are if this cab had been fued by cng or propane there would have been no bang as the fuel would have stayed inside of a nice safe tank instead of spilling out of a plastic or tin tank

          agree,
          I'm guessing here....
          In the event of sheering off a valve, I think CNG would be safer because it will dissapate upwards but propane would be ground hugging and allow a flash burn if ignited. Same goes for a tank getting shot, if that would even penetrate it after passing through a car body.

          In a house natural gas leak the room fills from the ceiling down to the pilot lights in the house then boom.
          Propane would fill upwards to the pilot before it flash burns.

            Not so. A Super Shuttle driver was killed a few years back when the CNG tank exploded while he was filling it. The van had previously been rear ended, denting the tank. Battery acid from the offending car got onto the tank and also weakened it. The tank was inspected, but not properly and likely not by someone qualified to do so. I tried to find the discussion of the accident on the forum, but was unable to find it. There are several references to it in the posts on tank safety.

            A man who was working on a CNG system was also killed recently. Here is the discussion on that: http://cngchat.com/forum/showthread....-tank-explodes

            There have also been some recent serious injuries here in the USA:

            This is why many of us get just a little anxious when an obvious non-EPA install pulls up at the station and starts filling up before we can move ourselves out of harm's way. It seems that those who do not install EPA-approved systems are not properly trained to do a safe install, regardless of their opinions to the contrary.

              On my most recent visit to Las Vegas I observed an apperant majority of cabs were propane but some were gasoline. I did not see any cabs on CNG. I filled up my vehicle and paid $2.76 per gallon equivalent the highest I have paid in my state to state travels.

                Please do NOT start speculation on whether taxi was CNG . . . . CLEARLY by video looks like liquid fuel was spilled and burning. Last thing that cng movement needs is bad press that is false! If that taxi would have been dedicated cng, there likely would have been NO FIRE at all.

                About midway through the link to Las Vegas Sun article, they finally get it right:

                Please . . . . Contour2000 . . . . research and understand HOW the properties of Natural Gas make it MUCH safer than liquid fuel:
                a) Natural Gas is lighter than air so it rises and dissipates where there is a leak
                b) Natural Gas has a higher combustion temperature than liquid fuels like normal petrol gasoline or diesel
                c) Natural Gas behaves DIFFERENTLY than Propane (ie LPG/propane is heavier than air and settles in low spot on ground)
                d) Finally, cng tanks for Natural Gas are OVER-Engineered to withstand burst pressure, fires, etc. making them MUCH SAFER than any other comparable fuels such as gas, diesel or propane

                    I have seen international stories about such problems in Pakistan and some other areas where the tanks or fittings were defective or deficient compared to our standards. Buildings and pipes seem much more vulnerable from what I see in my searches. The old steel tanks were bullet proof. It is a good point that the bullet would have to go throught the vehicle, as that would slow the velocity, and change the shape, unless it was full metal jacket. I am told that the advanced tanks might leak after hit, but will not puncture with an average bullet.

                      CNG is non existent in the Las Vegas taxi / shuttle business. It seems the highest fuel tax goes on CNG in Nevada, the lowest is propane.

                        Sneed, your so sensitive. I was not starting speculation. I was the one who posted the relevant portion of the article below, well before anyone else saw the post or replied. Why do you repeat and expand on the concept I mentioned on cng vs propane while calling me ignorant. jerk
