All of the University of Delaware campus buildings that closed and evacuated on Wednesday afternoon for a “safety-related incident” in the Lammot du Pont Laboratory will reopen for classes Thursday morning, the university announced Wednesday night.
The evacuation took place after researchers in the lab “inadvertently produced a small amount of a shock-sensitive explosive chemical,” according to the university.
UD called it an isolated incident and said there is no threat to campus health or safety. No injuries were reported.
Delaware State Police’s explosive ordinance disposal unit removed the chemicals from the lab on Wednesday and took them to a “safe location” on the South Green for a “controlled detonation” at 5:45 p.m., according to the university.
