Overview and Objectives
Understanding the risks present in your location, the likelihood of
occurrence, and your center's preparedness for these events serve as
the foundation for all hazard emergency management plans. This
session will review components of a typical Hazard Vulnerability
Analysis (HVA), will guide health centers through completion of a
sample HVA, and discuss how to integrate the HVA into an emergency
management plan.

2. Concern of occurrence
2. Geographically sensitive
a) Impacts
• Human (injury versus death)
• Property (patient care?)
• Business (critical function?)
b) Mitigation
• Preparedness (plans, policies, protocols)
• Internal Response (competency)
• External Response (MOU, MAA, exercises)
