Our QRA goal is to not only help you comply with regulations but to also provide the necessary information and guidance to assist you with making informed and effective risk mitigation decisions. We achieve this by leveraging knowledge obtained from our research and development programs with years of testing mitigation solutions implemented at facilities including building upgrades, window/door upgrades, and building leak tightness improvements.
BakerRisk professionals partner with your team to provide Quantitative Risk Assessment (QRA) results that go beyond simply quantifying the exposures. We present the data to prioritize risk contributors and identify the most practical, feasible, and actionable risk mitigation solutions.
We present QRA data in a way that allows you to identify sources that cause the greatest risk as well as the locations that present the greatest risk to personnel. This data can then be compared to internal corporate standards or, when applicable, governmental criteria. In addition, we can perform sensitivity studies that quantify the level of risk reduction that can be achieved with potential risk mitigation strategies to support your decision making and provide justification for investments.
QRAs provide an objective, quantifiable analysis of the potential risk exposure to personnel, assets, market, and ecological and environmental impact. It is a powerful tool when combined with the right professional guidance; a detailed QRA can guide you through the unknown demonstrating individual and societal risk results, allowing for an informed decision making process.
The BakerRisk QRA process uses a data intensive approach that removes the guesswork in identifying a maximum credible event by including all process equipment with hazard potential, and modeling a range of release sizes with a range of statistically applicable weather conditions (wind stability, wind speed, and the full wind-rose). With the aid of our software tools SafeSite3G© and QRATool©, our professionals are able to model a range of potential unique outcomes - a few for small units to millions for large-scale facilities.
The typical QRA process includes:
Gathering receptor or occupancy data to convert consequence hazards into exposure vulnerabilities.
Estimating release frequencies and conditional probabilities for weather conditions, wind direction, ignition probability and timing, and time of day.
Calculating risk based on frequency estimates and consequence results.
BakerRisk documents each QRA in a comprehensive report that defines inputs, explains calculation methods, provides interim calculation results to allow verification and validation of the methods employed, and summarizes results in a range of meaningful measures. Our QRA methodology can produce onsite and offsite risk results in several formats including individual risk results, societal risk results, and frequency exceedance curves/contours.
Individual risk results include:
- Location (building/area) individual risk
- Work group individual risk
- Maximum individual risk
- Geographic individual risk
Societal risk results include:
- Location (building/area) societal risk
- Source societal risk
Frequency exceedance curves/contours include:
- Frequency-consequence (F-N) curves
- Frequency-pressure (F-P), frequency-impulse (F-I), frequency-thermal (F-therm), frequency-toxic (F-tox) curves
- Frequency-pressure (F-P), frequency-impulse (F-I), frequency-thermal (F-therm), frequency-toxic (F-tox) contours
