“Active” Radon gas mitigation system, i.e., the system fan operates continuously, we inspect visible components: There is an “active” Radon gas mitigation system, i.e., the system fan operates continuously. The pressure sensing device provides visual indication that the fan is operating. If there is no electrical power, the Radon Gas mitigation fan will not operate. When electrical power is restored, the fan should automatically resume operation. We inspect visible components of the Radon Gas mitigation system.
“Passive” Radon gas mitigation system, i.e., there is not a system fan, we inspect visible components:There is a “passive” Radon gas mitigation system. There is not a fan installed at this time. We inspect the visible components of the Radon Gas mitigation system.
