Situational Awareness
Deviation / Discrepancy - Procedural Hazardous Material Violation
Air Traffic Control Provided Assistance; Flight Crew Returned To Gate
Procedure; Human Factors
Flight pushed from the gate; I received an alert that the ramp was unable to closeout the flight due to no 15 bags surrounding the Hazmat. The total bag count on the flight was only 12. The flight was brought back to the gate to offload the Hazmat.
Commercial airline personnel reported Hazmat cargo incorrectly configured for air transport resulting in ground return to unload Hazmat.
