How must a zone be left at the end of a shift?

At the end of a shift, leaving a zone deactivated is the correct procedure to ensure the safety and security of the area. Deactivating a zone means that all operations within that specific zone are halted, preventing any potential unauthorized access or activity during the transition between shifts. This practice is vital for maintaining control of the environment and ensuring that subsequent operators can start their shifts without any lingering issues or risks.

In the context of operational protocols, a deactivated zone allows operators to conduct necessary inspections or maintenance and ensures that any alarms or monitoring systems are not active until the next operator is fully prepared to take over. By having a clear protocol of deactivating zones, it reduces the risk of accidental alarm triggers or miscommunications that can arise when zones are left active or unmonitored.
