Defusing sessions should do which of the following in order to be successful?

Comprehensive and Detailed Explanation From Exact Extract:

Defusing is an informal, short-term intervention after a critical incident. It should:

Occur within hours of the event (ideally the same shift)

Encourage voluntary open discussion in a confidential setting

It is not a full debrief or counseling session and doesn’t require mental health professionals present. Forcing participation or waiting too long (e.g., 72+ hours) can reduce its effectiveness.
