Thanks for some more detail. First round claims were chlorine gas, that I saw. Im not in the area but was wondering actual contents of the load being transported.
Edit: I replied before seeing some of the links and further comments. Hopefully people in the region pay attention to some details on this. If whats being reported is truthful this is quite serious, not just for the town or few mile radius.
