Derailed train near Washington leaks hazardous material

WASHINGTON (Reuters) - A CSX freight train derailed in northeastern Washington, D.C. on Sunday, spilling hazardous material near a city subway station, and emergency workers were cleaning up the site after plugging the leak, officials and the railroad company said.
Thirteen cars were overturned in the early hours of the morning but there were no injuries. The substance that leaked was sodium hydroxide, used to produce household products including paper, soap and detergent.
"We don't know how much leaked. That's the process, trying to figure that out. The fumes should not cause you any problems," District of Columbia Fire Department Deputy Chief John Donnelly said at a news conference.
The District fire department did not order evacuations around the site of the accident, which happened near a city subway station and about three miles (5 km) from the White House.

Sodium hydroxide - the main ingredient in many drain cleaners - is toxic on ingestion since it can dissolve tissues before being neutralized by stomach acid, and corrosive on skin contact - if one spills it on one hands (I have done this) your hands feel a little soapy from the saponification of fats in one's skin, but nevertheless this type of spill is fairly easy to achieve remediation.
Any fumes are probably just steam, since the dissolution of sodium hydroxide in water is fairly exothermic.
