Apparatus Positioning is Always Crucial

Including at Vehicle Fires

WE ARE SEEING MORE AND MORE of these types of transit buses all over, not just North America, but in Europe and some Asian countries as well.

That big, box thingy on the roof is the fuel tank for the compressed natural gas that is used to propel these coaches.  Naturally, firefighters immediately begin thinking "fire problems here" when we see that.  How about the relief valve on that tank?  Do you know where it is?  We are accustomed to overheated or overpressured tanks venting at the top, in the valve assembly usually.

But how about these buses?  No indication of the vent or fill valve at a glance.  So if you have some in your response area, have you taken the time to find out where they are?

Chief Billy G. sent along this video of a CNG-powered bus in Wassenaar, Netherlands, that vented after the firefighters were on the scene.  Think about this and pass it along:

    DC METRO started using the Compressed Natural Gas (CNG) buses over 10 years ago, and has about 2,200 in service currently.

    Chicago Transit had as many as 1700 propane powered buses in service from 1952 or so to 1972 – not sure of exact dates. After watching the video it appears that they left it vent and burn. Tanks appeared frayed but did not look like they failed . Propane is routinely used to fuel buffers in most commercial buildings, so “its everywhere” to some degree.

    The natural gas industry is going full tilt at building CNG and Liquified Natural Gas (LNG) service stations across the country to support more use of CNG/LNG powered vehicles.
