Intended to build on emergency response training that Head Start staff receive, this guide assists staff and parents in understanding the causes of childhood injuries, and planning steps to more effectively prevent and manage children's injuries in the Head Start program, at home, and in the community. Following an introductory section, the guide presents three training modules. Each module details expected outcomes, key concepts, background information, learning activities, and next steps. Handouts are included for each module. Module One, "Understanding Childhood Injuries," helps participants understand the common causes of childhood injuries and their relationship to child development. Module Two, "Preventing Childhood Injuries," helps participants create, maintain, and supervise a safe environment in the Head Start program and at home, and also establish and teach safe practices to staff, children, and families. Module Three, "Preparing for and Managing Emergencies," helps participants prepare policies, procedures, and provisions for emergencies and to review injury patterns to improve injury-prevention efforts. The final sections of the guide contain continuing professional development information and resources for further study. Two appendices address safety for young children and provide a health and safety checklist. (SD)
