QRA Process

Our QRA methodology.

The goal of any analysis is not only to help you comply with regulations, but also to provide the information necessary to assist with making informed and effective risk mitigation decisions. We are here to help. Our quantitative risk assessment process uses a data-intensive approach to remove the guesswork in identifying maximum credible events. The typical process includes analyses in a few key areas:

  • Consequence: We gather receptor or occupancy data to convert exposure vulnerabilities into consequences.
  • Likelihood: We estimate release frequencies and conditional probabilities for weather conditions, wind direction, ignition probability, and time of day.
  • Risk: We calculate risk based on frequency estimates and consequence results.

With our cutting-edge software tools SafeSite3G© and QRATool©, our professionals can model a range of potential unique outcomes, ranging from a few for small units to millions for large-scale facilities. This ensures that potential significant fire, explosion, and toxic hazards at your facility are thoroughly identified and assessed.

QRA Process

What you’ll learn from a BakerRisk Quantitative Risk Assessment.

We document each quantitative risk assessment in a comprehensive report that defines inputs, explains calculation methods, provides interim calculation results, and summarizes them in a range of meaningful measures which allows them to be reviewed/interrogated in detail. Our QRA approach provides and presents results (onsite/offsite) in terms of frequency exceedance curves and contours, societal risk, and individual risk  to provide a comprehensive picture of the risk profile and can be compared to internal corporate standards or when applicable, governmental criteria.  Societal risk results are presented in tables showing sources contributing the greatest risk and locations that are predicted to incur the greatest risk at the facility. Risk results tables also identify the contribution of risk by explosion, fire, and toxic hazards so that they can be easily used to identify potential risk refinement and mitigation strategies, and to make informed and effective mitigation decisions, as necessary.

BakerRisk’s unique risk assessment and analysis program.

QRATool© allows us to combine initiating event frequencies, ignition probabilities, weather distribution probabilities, and occupancy data with explosion, fire, and toxic vulnerabilities from simulated releases to conduct precise and efficient risk assessments. Our consultants utilize QRATool© to evaluate and prioritize risk drivers, streamlining the evaluation of mitigation strategies to reduce identified risks to tolerable levels. When combined with our rigorous quantitative risk assessment methodology, this approach empowers our teams to accurately determine the process risks affecting personnel within a facility and/or the public. QRATool© efficiently supports study updates and revalidations to allow project teams and organizations to quickly understand existing and future impacts of proposed changes to facilities, as well as effectively supports the front-end loading (FEL) design stages of capital projects.
