Signal 30 corresponds to which incident?

• A. Fireworks
• B. Explosion
• C. Fight in Progress
• D. Intoxicated Person

Answer: (B)

Understanding how incident signals map to events helps responders move quickly to the right kind of scene. When a caller reports an explosion, it indicates a sudden, high-hazard situation with blast effects that can cause fires, structural damage, and injuries. Treating it as a top-priority event means rapid deployment, securing the area, and coordinating with fire services (and potentially specialized units) to assess risk, evacuate if needed, and manage the scene.

Fireworks, while hazardous, are a different kind of incident and typically fall under a separate signal category that doesn’t automatically imply a blast with structural risk. A fight in progress describes ongoing violence requiring containment and medical aid, not a blast scenario. An intoxicated person is a welfare-related or disturbance call, not the explosive hazard meant by an explosion signal.
