What did command request minutes after the first company arrived on scene?

Command requested an additional two engines and one ladder, followed by a full second alarm, because the initial incident assessment indicated that the situation was more complex and demanding than anticipated. After the first company's arrival, they likely recognized the need for more resources to effectively manage the incident, indicating a growing emergency requiring extra manpower, equipment, and support.

This action reflects common incident command protocols where the response escalates based on the assessment of the incident's dynamics, hazards, and the number of people potentially affected or at risk. By calling for additional resources, command was ensuring that they were prepared to handle the situation comprehensively and safely, which is pivotal in emergency response operations.
