Which personnel should not serve as a primary casualty notification officer?

A primary casualty notification officer should not be a person who is closely related to the deceased or injured, as their emotional connection may hinder their ability to communicate the news effectively. Additionally, personnel who lack training in crisis communication or who may struggle with emotional stability in high-stress situations should be excluded. It is also advisable to avoid individuals with a history of poor interpersonal skills or those who may have biases that could affect their objectivity.
