August 10 Update
Portions of Building 67 (Molecular Foundry) were reopened in stages on Thursday as Foundry and Lab EHS teams performed walkthrough inspections to identify potential remaining hazards. Water damage was found to be minimal. As of 4:00 pm Thursday, Building 67 had resumed normal operations except for restrictions in specific labs and offices.
The inspections followed an evacuation on Tuesday evening, August 7, after an unexpected chemical reaction resulted in activation of the building’s fire suppression system and subsequent flooding of portions of the building.
No injuries were reported, and the incident presented no threat to public health or safety.
