The train that derailed in northern Maine on Saturday was carrying the hazardous chemical pentamethylheptane, which is highly flammable and toxic to humans, according to the railroad. The train was also carrying ethanol. Both chemicals are flammable, and pentamethylheptane is classified as highly flammable by the U.S. Department of Transportation. Cleanup continued Sunday at the site, where six cars derailed and started a small forest fire. The cars containing the hazardous materials were not involved in the fire, and there were no leaks or spills, according to the railroad.
