In a Reported Structure Fire with a single 911 caller reporting flames in or coming from a structure, how many Engines or Aerials are assigned?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

The situation tests knowing how the initial alarm is sized for a reported structure fire with a single caller. In this scenario, the goal is to get enough resources on scene quickly to start an attack, establish water supply, and begin size-up and possible searches. The standard initial assignment is two engines or aerials, meaning two apparatus capable of performing the core early tasks. This two-unit starting point provides the needed balance between rapid action and safe, effective operations without overcommitting resources before the size-up confirms the exact needs. If conditions indicate a larger or more complex fire, more units would be added, but the minimum initial response for this scenario is two.
