How do you ensure accuracy when multisource data is broadcast in a 900 code?

• A. Rely on the most senior officer's word.
• B. Broadcast immediately and correct later.
• C. Cross-check with units on scene and verify with dispatch.
• D. Assume data is correct if it comes from a supervisor.

Answer: (C)

When multisource data is broadcast, accuracy comes from confirming details with those on the ground and with the dispatch center to create a single, reliable picture. On-scene units have real-time observations—exact location, status, hazards, and changes as they unfold—while dispatch maintains the official incident record and can verify specifics like unit assignments, timing, and the nature of the threat or problem. By cross-checking these sources, you reduce the chance of acting on outdated or contradictory information and improve coordination across teams. This approach also helps prevent the spread of rumors or partial data that can mislead responders and create safety risks.

Other approaches overlook how quickly information can evolve. Relying on the most senior officer’s word may still miss recent changes. Broadcasting information immediately and correcting later can spread confusion and lead to unsafe actions. Assuming data is correct simply because it comes from a supervisor relies on authority over verification, which isn’t reliable in dynamic incidents.
