UPDATE (2:26 p.m.): Eddie Kim reports that “one side of the street” is now “open to cars” and that he was let out of his lockdown situation. Things sound like they’re calming down a bit; Eddie also notes that fire trucks are leaving the scene. D.C. Fire and EMS have tweeted that there is “no known threat.”

A chemical spill on the 900 block of F Street NW has closed down most access to the street this afternoon. According to DCist’s Eddie Kim, several businesses along that stretch of F Street, including Cowgirl Creamery, have been placed under a precautionary lockdown. Pedestrians are also not being allowed through the area at this time. D.C. Fire and EMS are on the scene and working to identify an unknown substance which is leaking from a package.

There have been no injuries reported so far. We recommend avoiding the area until things clear up and we’ll update with more details when we get them.
