A Multiple Alarm situation is

• A. An incident that requires additional resources beyond the initial response.
• B. An incident with only one unit on scene.
• C. A false alarm that ends immediately.
• D. A routine medical call.

Answer: (A)

A multiple alarm means the incident requires additional resources beyond the initial response. It signals that the situation is larger or more complex than what a single engine crew can handle, so more engines, ladder trucks, and possibly mutual‑aid teams and a bigger command structure are brought in to control the fire, protect exposures, and perform rescue as needed. This escalation is what sets apart a true multiple-alarm scene from a scenario with only one unit on scene, a false alarm that ends quickly, or a routine medical call, none of which require the extended resources and coordination that a multiple alarm entails.
