BANGOR, Maine — Employees have returned to Building 4 in the St. Joseph Healthcare Park on Broadway after air quality tests showed the workplace should be safe.
The building was evacuated Friday and again on Monday after several employees complained of congestion, sore throats and breathing problems. Crews had removed a water-damaged section of carpet and a section of drywall near the entrance to the building on Friday.
After employees left Monday, St. Joseph Healthcare brought in a crew to do an “independent environmental review” and inspect air quality in the building, Bethany McKnight, vice president of mission and system integration, said Thursday afternoon.
The tests showed air quality and spore levels inside the building were healthier than outside. The results were confirmed by a state-certified lab, she said.
“There’s no indication there was a mold issue,” McKnight said.
McKnight said inspectors believe that when the carpet and drywall were torn out, particles went airborne and caused discomfort for employees. After a thorough cleaning and air filter replacements, the problem appears to be resolved, McKnight said.
The employees returned on Thursday and so far have not needed to be relocated, McKnight said.
Building 4 houses several support offices for St. Joseph Healthcare, including receiving, billing and fiscal services. The number of employees stationed in the building was not immediately available. Patients don’t use the building.
