The Helping Emergency Responders Overcome (HERO) Act seeks to enhance mental health services for public safety officers by establishing a comprehensive national data system. This system, known as the Public Safety Officer Suicide Reporting System , will collect detailed data on suicide incidence among these officers, disaggregated by various demographics and occupational statuses, to facilitate the study of effective interventions. Crucially, it mandates strict data privacy and security measures to protect the confidentiality of individuals and prevent data misuse, such as denying benefits. The Secretary will submit annual reports to Congress on suicide incidence, which will be made publicly available. The bill also authorizes the Secretary of Health and Human Services to award grants for establishing or enhancing peer-support behavioral health and wellness programs within fire departments and emergency medical services agencies. These programs would train career and volunteer members to serve as peer counselors. Additionally, grants are available for similar behavioral health and wellness programs for healthcare providers, offering confidential support and training peer counselors within hospitals and other facilities. Furthermore, the legislation directs the Administrator of the U.S. Fire Administration to develop resources for educating mental health professionals on the unique culture, stressors, and challenges faced by firefighters and EMS personnel, including retired members. It also requires the Secretary of Health and Human Services to develop and update evidence-based best practices and resources for identifying, preventing, and treating post-traumatic stress disorder (PTSD) and co-occurring disorders in public safety officers. These resources will be made available to relevant agencies and incorporated into federal training programs for public safety officers.
