Chattanooga, TN – Two Holiday Inn Express employees fell ill over suspected exposure to carbon monoxide.

Officials with the Chattanooga Fire Department say they responded to the Holiday Inn Express on Hixson Pike around 10:30 a.m. Tuesday.

They say two housekeepers were in a basement laundry room when they began feeling dizzy and nauseous. One of the house keepers got physically sick.

Firefighters evacuated the building. They used gas monitors to check the building and found elevated levels of carbon monoxide.

The building was ventilated and aired and deemed safe to return to.

The two women were taken to Memorial Hospital Hixson for treatment.

Motel management and Chattanooga Gas officials are working to determine what caused the leak and repair it.
