QRA Services – Risk Management Professionals Inc.

QRA utilizes a number of tools that provide a more detailed estimation of the expected frequency and consequences of potential accidents associated with a facility or operation. QRA is the next level of risk analysis, and it can require a significant amount of additional effort for more accurate hazard modeling and statistical estimation of scenario frequencies. However, it does yield the most insights. For this reason, a complete QRA (note that focused applications are fairly common) is typically applied only to the highest-hazard processes. 

Many consequence modeling tools are available that support the modeling of vapor cloud, fire and explosion hazards to provide an accurate, numerical indication of the magnitudes that must be assigned to each consequence category. Given the large numbers of scenarios that may be applied for a complex QRA, Risk Assembly software may be utilized to link the consequence bins with the associated scenarios and their frequencies, generate societal and individual risk values, and perform various graphing functions. Risk Management Professionals personnel have developed detailed QRA for refinery alkylation units and nuclear power plants.
