In this session, attendees will learn from the experiences of the Denver Fire Department Peer Support Team in their response to five different line-of-duty deaths suffered over a two-decade period. Peer support team notification, activation, response, and grief counseling will be topics of discussion. Lessons learned regarding successes and mistakes will also be covered in relation to providing services to our fellow firefighters and their families. Justification for the need of fire department and emergency service peer support teams, specific to the line-of-duty deaths, will also be discussed. Attendees will receive information that will help any new or existing peer support team.
