Epping (N.H.) Regional Health Center was evacuated Aug. 9 after at least 10 staff members began feeling sick, WMUR-9 News reports.
The employees reported feeling dizzy, lightheaded and a tightness in their chests, and were evacuated to nearby Exeter (N.H.) Hospital for treatment shortly before 3 p.m., according to the New Hampshire Union-Leader.
Epping Regional officials evacuated the building as a precaution. No patients were affected.
It is unclear what made the staffers ill. Firefighters reportedly initially believed carbon monoxide may have been to blame, but it was later ruled out. Investigators did not find any flammable gases in the building, WMUR-9 reports.
A spokesperson for Exeter Health Resources, which is affiliated with Epping Regional and Exeter Hospital, told WMUR-9 in a prepared statement: "We're so fortunate to work with such great communities and great first responders that come out to help in these situations. We're always thankful for the support of the fire departments and the police departments, especially in these types of situations for the interest and safety of our patients and staff."
Epping Regional will remain closed Aug. 10 and is expected to reopen Aug. 13.
