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:
