The patient had a “possible exposure to an unknown substance,” and was brought to the ER for treatment.

As a precaution, ambulances were diverted from the hospital for less than a half an hour Thursday afternoon. And those staff members went through a “basic decontamination” process.

Officials say the hospital is now back to “operating as normal.”
