A principle of management that the Incident Commander should consider as an incident grows is to maintain what?

Maintaining the span of control is essential for effective incident management as the complexity and number of resources involved in an incident increase. The span of control refers to the number of personnel or units that one supervisor can effectively manage. A recommended ratio in emergency services is typically between three to seven subordinates per supervisor.

As the incident grows, it's crucial for the Incident Commander to ensure that each team or individual has appropriate supervision to maintain communication, accountability, and operational efficiency. If the span of control exceeds optimal levels, coordination can break down, leading to confusion, overlapping responsibilities, and potential safety issues.

While other considerations such as accountability of equipment, limited radio traffic, and scene control are important, they do not specifically address the need for effective management of personnel in the context of growing incidents as directly as span of control does. Effective span of control enables clear leadership and operational success in dynamic and high-stress environments like those faced during vehicle rescue operations.
