Code 928 denotes which incident?

• A. Investigation - Incendiary Device
• B. Explosion - Bomb Threat
• C. Explosion
• D. Fire

Answer: (C)

In these police radio codes, the 900-range covers major incident types, with 928 specifically signaling an Explosion. This designation tells responders the scene has seen a blast event and may involve hazards like structural damage, debris, and potential injuries, guiding them toward explosion-safety precautions and appropriate resources.

The other options don’t fit because they describe different scenarios: an incendiary-device investigation is about suspect devices and would use a different code focusing on investigation of such devices, a bomb-threat label refers to the threat itself rather than an actual blast, and a fire code covers burning incidents without an explosion. So 928 is used precisely for an explosion, even if fire or other elements are present.
