The Delray Beach Fire Chief has moved firefighters out of a station for health concerns.
A department spokesman says engineers doing an air quality test found a potential issue with how two air conditioning vents are connected at Station Three on Linton Boulevard near I-95.
Some firefighters are sleeping in an RV behind the station for the time being.
The department expects more test results in seven to ten days and then it will decide how to move forward.
The city has long-term plans to replace the fire station.
