  1. Which analysis technique is used to identify all the ways a system component can fail and the effects those failures have on the overall system?

    Answer: Failure Mode and Effects Analysis (FMEA)

    FMEA systematically examines each component of a system to identify potential failure modes, their causes, and the effects on system performance.

  2. In the context of dam safety risk assessment, the 'probable maximum flood' (PMF) represents:

    Answer: The most severe flood considered reasonably possible based on meteorological and hydrological conditions

    The PMF is the largest flood considered physically possible at a site based on extreme meteorological and hydrological conditions, used as the standard for high-hazard dam design.

  3. When conducting a community wildfire risk assessment, the term 'fire environment' encompasses which three components?

    Answer: Fuel, weather, and topography

    The fire environment triangle consists of fuel (type, amount, moisture), weather (wind, temperature, humidity), and topography (slope, aspect), which together determine fire behavior.

  4. A local emergency manager uses a Geographic Information System (GIS) to overlay flood inundation zones with census block population data. This process is an example of:

    Answer: Spatial exposure analysis

    Overlaying hazard zones with population or asset data in GIS constitutes spatial exposure analysis, identifying what and who is located within the hazard's impact area.

  5. Which federal program requires facilities handling extremely hazardous substances to submit risk management plans that include hazard assessments with worst-case release scenarios?

    Answer: Clean Air Act Risk Management Program (RMP)

    The Clean Air Act's Risk Management Program (40 CFR Part 68) requires covered facilities to develop RMPs that include worst-case and alternative release scenario analyses.

  6. The Sendai Framework for Disaster Risk Reduction 2015-2030 established a global target to reduce disaster losses. Which of the following is one of the seven global targets?

    Answer: Substantially reduce global disaster mortality over 2005-2015 averages by 2030

    Sendai Target A calls for substantially reducing global disaster mortality by 2030 relative to the 2005-2015 baseline, guiding national and local risk reduction investments.

  7. In risk analysis, 'residual risk' is defined as:

    Answer: The risk remaining after mitigation controls have been implemented

    Residual risk is the level of risk that persists after all feasible mitigation controls have been implemented, representing what a community must accept, transfer, or monitor.
