Emergency services personnel are truly valuable assets to every community and city. They enter into the worst situations, establish control, provide aid, and right the wrongs. The work of public safety is challenging and at times overwhelming. Being a first responder can take a significant toll on those who serve. Code Four: Surviving and Thriving in Public Safety is a survival guide for first responders. Designed to normalize what first responders face and to offer solutions, this book is written to teach public servants how to care for themselves and how to implement the necessary cultural changes to improve mental health in emergency services.
