About HVAs

Table of contents

The hazard vulnerability analysis (HVA) is an emergency preparedness tool for evaluating the likelihood and impact of hazardous situations. The results of the analysis are then used to guide preparedness efforts and ensure compliance. Some facilities, such as hospitals, are required to complete HVAs annually to demonstrate compliance with the emergency preparedness regulations for their industry.

Assessment Steps

Accessed through the Planning menu in eICS, a wizard-like process helps you complete HVAs in three main steps. The process entails: 

  • Associating hazards with actual incidents
  • Evaluating the threat of hazards
  • Reviewing and finalizing the assessment

By associating hazards with actual incidents, the HVA tool enumerates the occurrence of hazards and links this information to incidents and their incident response guides (IRGs). The next step involves assessing the probability and impact of hazards, along with your facility’s level of preparedness. The information from these steps is combined and presented as a ranking of hazards, which should be reviewed prior to finalizing the assessment.


HVA results are also accessed through the Planning menu. On the Hazard Vulnerability Analysis page, administrators can view the status and results of assessments to learn about risks and vulnerabilities for their facility, coalition, health system, and/or domain.

After selecting your facility or organization at the top, two lists appear that indicate assessment statuses and top risks. Basic information about assessments is presented in one table, with links to Print, View, and/or Update. The other table, Top Risks, presents ranked hazards, along with the number of actual incidents that occurred during the assessment period, the percentage vulnerability, and the level of preparedness.


Vulnerability is a percentage that indicates the comparative significance of a hazard. It is calculated based on answers provided on the Threat Evaluation regarding probability, magnitude, and mitigation.

Preparedness, on the other hand, is your response on the Threat Evaluation regarding a facility’s level of pre-planning for the hazard. At the coalition, domain, or health system level, preparedness includes the responses from all facilities in the group and indicates the percentage of facilities that provided each response.
