UPDATE 7:55 p.m.: Fire Department officials determined that the substance that evacuated a Loudoun County Facility the afternoon of April 20 was not hazardous.
Test results proved the substance was non-hazardous and that the employees were not in danger.
Crews removed the envelope and cleansed any exposed area before escorting remaining employees back inside the building, Rinehart said in a release. No first responders were injured during this incident.
UPDATE 5:18 p.m.: One of the three potentially exposed patients have been transported to the INOVA Loudoun Cornwall Campus complaining of general illness which was not related to the suspicious powder. Rinehart said they were transported as a precaution.
A second hazmat team has entered the building to run more tests on the envelope with the substance, she said.
UPDATE 4:54 p.m.: The Loudoun County Fire and Rescue Hazmat team is testing the substance but so far test are inconclusive, Rinehart said.
Three people were potentially exposed to the substance, while only one handled it directly. All three have been decontaminated and are still in the building, Rinehart said.
Rinehart said it is not yet known how the substance got into the building or who it was addressed to, only that it was found on the second floor of the building.
