What information should be communicated to all personnel when command is transferred?

The effective time and date of the transfer is essential information to communicate to all personnel when command is transferred. This ensures that everyone involved is aware of when the change in leadership occurs, which is crucial for maintaining continuity in command and ensuring that all actions taken after the transfer are aligned with the new commander's directives. Having a clear understanding of when the command changes hands helps to prevent any confusion or overlap in responsibilities, which can be critical in high-pressure situations typical of incident management.

While knowing the name of the new commander, the reason for the transfer, and the location of the command post are also important, these elements may not hold the same level of immediacy as the timing of the command transfer, which directly impacts operational decision-making and communication flows.
