Fire Department (F.D.) responses to hostile and violent situations are becoming more frequent. Such incidents include, but are not limited to, large scale complex incidents such as school shootings, workplace violence, and terrorist activities, as well as smaller scale/less complex incidents such as suicide attempts, single patient shootings and stabbings, domestic violence injuries, and assaults. The goal of this guide is to ensure coordination between agencies resulting in scene control, patient treatment, and evidence preservation while maintaining the safety of all emergency personnel.
