True or False: The radon mitigation system should have a switch or labeled breaker to turn off the fan.

Having a switch or labeled breaker to turn off the fan in a radon mitigation system is considered best practice. This feature is essential for several reasons.

First, it allows for easy access to turn off the fan for maintenance, repairs, or servicing without needing to disrupt the entire system or risk exposure to radon if maintenance is done improperly.

Second, ensuring that the fan can be safely turned off helps in situations where monitoring is necessary. For instance, if a homeowner wishes to measure radon levels during a specific period without the system's influence, they can easily turn off the fan.

Finally, clear labeling of the switch or breaker enhances safety and ensures that anyone (including homeowners and service personnel) can quickly identify and operate the fan correctly. This contributes to better overall management and understanding of the radon mitigation system's functionality.
