Which zone requires stricter monitoring when personnel transition to it?

The focus on stricter monitoring in this context is primarily due to the specific risks associated with Zone 1. This zone typically encompasses areas that are deemed to have the highest levels of security risk or hazard potential, often requiring additional layers of oversight and checks to ensure safety and compliance.

Personnel moving into Zone 1 may be interacting with sensitive systems or data, which necessitates rigorous screening and monitoring procedures to prevent unauthorized access and to mitigate potential threats. This zone could be related to areas dealing with critical infrastructure, sensitive information, or other high-risk activities, which demand heightened vigilance during transitions.

The other zones, while they may have their own levels of monitoring, do not typically require the same intensity of scrutiny as Zone 1, which further underscores why this distinction is vital in regards to personnel movements.
