Quantified Risk Assessment
Quantified Risk Assessment is simply a fully quantified risk evaluation/analysis approach where both the consequences and likelihoods of hazardous scenarios are determined numerically. The output is often in the form of risk contours, which depict the individual risk for people located in a particular place, from all hazardous scenarios on a site which can impact them.
QRA is often used for Land Use Planning issues by the Regulators – determining whether a new development should go ahead or not. Its use for depicting the risks to on-site personnel or members of the public off-site within COMAH safety reports is not generally required.
HFL Consulting can advise on the need for QRA and use the recognised tools and techniques to carry out a full and detailed assessment, should one be necessary.
