  • 1. Risk Evaluation Determines the relative seriousness of hazard risks as they affect the local community
  • 2. “ [The] public [is] willing to accept voluntary risks approximately 1,000 times greater than involuntary risks” Keith Smith, in Environmental Hazards: Assessing and Reducing Disaster
  • 3. 3 Methods Used to Evaluate Risk
    • Creating a risk matrix
    • Comparing hazard risks against levels of risk estimated during the analysis process with previously established risk evaluation criteria
    • Evaluating risks according the SMAUG methodology
  • 4. FEMA Risk Matrix Values
    • Class A : High-risk condition with highest priority for mitigation and contingency planning (immediate action)
    • Class B : Moderate-to-high-risk condition with risk addressed by mitigation and contingency planning (prompt action)
    • Class C : Risk condition sufficiently high to give consideration for further mitigation and planning (planned action)
    • Class D : Low-risk condition with additional mitigation contingency planning (advisory in nature)
  • 5. Risk Matrix Example Source: Federal Emergency Management Agency. 1997. MultiHazard: Identification and Risk Assessment . FEMA. Washington, DC. P.315
  • 6. Risk Register
    • Name of the Risk
    • Qualitative likelihood value
    • Qualitative consequences value
    • Level of risk as determined by evaluation on the risk matrix
    • Priority rating
    • Additional information

    • Loss of life and harm to people’s health
    • Economic loss

    • Lifeline damage

  • 8. Hazards Risk Management Analysis Context
    • Legal requirements
    • Cost and equity
    • Risks that are clearly unacceptable
    • Risks that should be kept as low as reasonably practicable
  • 9. SMAUG Prioritization Process From Lunn, John. 2003. “Community Consultation: The Foundation of Effective Risk Management.” Journal of Emergency Management. V.1, No.1, Spring. Pp. 39-48. High Priority Low Priority The risk will increase quickly The risk will remain static G – Growth High Priority Low Priority The risk urgently needs to be fixed It could be fixed next year U – Urgency High Priority Low Priority The risk is the least acceptable in terms of the political, social, or economic impact It will have little political, social, or economic impact A – Acceptability High Priority Low Priority The risk could be most affected by intervention We can do little to affect the risk. M - Manageability High Priority Low Priority The risk will affect the most people and/or will cost the most money It will affect the least number of people or cost the least dollars. S – Seriousness Priority Rating Description Factor The SMAUG Prioritization Process
