What defines Stage 3 in emergency disturbance control?

Stage 3 in emergency disturbance control is characterized by situations where the disturbance is beyond the capability of on-duty staff to manage alone and necessitates the involvement of intra-departmental personnel support. This indicates that the incident has escalated to a point where additional resources, including specialized teams from within the department, are needed to effectively contain and manage the situation.

In this stage, communication and coordination among departments become crucial, as it often involves a collaborative effort to ensure safety and restore order. The need for intra-departmental support highlights the complexity of the disturbance and the potential for greater risk, requiring a more structured response.

The other options do not accurately reflect the dynamics of Stage 3. For instance, stating that containment can be handled without assistance contradicts the very definition of Stage 3, which signals the need for external help beyond the immediate team. Similarly, suggesting that containment can be managed solely by on-duty staff or that containment requires no assistance overlooks the critical escalation that defines this stage.
