What kind of information should change messages be based on?

• A. Current, accurate, relevant information
• B. Historical data
• C. Hypothetical scenarios
• D. Speculative rumors

Answer: (A)

Change messages should be based on current, accurate, relevant information. This ensures the update reflects the present situation, uses verified facts, and provides instructions people can act on. In a fire department customer-service context, that means communicating the exact changes—such as new hours, updated contact methods, service availability, or safety requirements—along with when the change starts and where to find official confirmation. Keeping information fresh and directly applicable helps prevent confusion, maintains trust, and supports safe, smooth service.

Historical data can inform planning, but it shouldn’t drive the content of the message itself. Hypothetical scenarios or rumors aren’t appropriate for change messages because they can mislead and cause unnecessary worry or unsafe actions.
