Duluth, MN (NNCNOW.com) --- A strong odor at the Essentia Medical Clinic 1st street building this morning has led to an evacuation of all patients and staff.

After several patients complained that the odor was making them nauseous, the Duluth Fire Department investigated and ordered a partial evacuation of the first and second floors.

After using gas monitors to evaluate the fumes they found no abnormal levels and people were allowed back in.

Since then more people, including patients and employees, have complained of nausea, headaches, dizziness and feeling faint.

In response Essentia sent all patients and employees home while an air quality company attempts to detect the source of the odor.

The First Street clinic only handles outpatients.

All appointments at the clinic are tentative until further notice. The clinic will remain closed on Wednesday.

The Duluth Fire Department has ruled out the possibility of carbon monoxide.
