Nobody was believed to be seriously ill, according to WUSA9. An earlier version of this story cited NBC4, which reported that three people were seriously sickened.
The leak was first reported by customers who began feeling sick in the California Nails salon.
Firefighters responded to a fire at an apartment complex on Columbia Pike this morning. The blaze was quickly extinguished, but not before causing some damage.
The fire broke out at one of seven buildings in the Archstone Columbia Crossing apartment community on the 1900 block of Columbia Pike. So far, no word on a cause.
The Arlington Fire Department is on the scene of a hazmat situation at N. Stuart St. & 9th St. N., near the Ballston Metro. Initial reports suggest a truck is leaking fuel into a storm drain.
Update at 3:00 p.m. — An ambulance was called for a man who was complaining of chest pains, apparently caused by the fumes. The hazmat situation itself appears to be under control.
Firefighters will use their recently-acquired Mobile Emergency Response Vehicles (MERVs) to travel through the tunnels. MERVs, which were used during the 2005 bombing of the London Underground, can reduce the time it takes first-responders to reach underground victims from 45 minutes to 4 minutes.
The exercise will take place between 9 AM and noon. The $1.2 million in funding for it came from a federal Homeland Security grant.
