Phast/Safeti enables the completion of comprehensive QRA studies, producing a range of risk measures that are compared against established criteria. These measures include the individual risk (IR), which calculates the risk to an individual based on their duration at different site locations and time away from the facility. Additionally, the location-specific individual risk (LSIR) evaluates the risk assuming an individual remains at a specific location for an entire year. Finally, the potential loss of life (PLL) provides a quantified average number of fatalities per year. By leveraging Phast/Safeti for regulatory compliance, organizations can effectively assess and manage risks, ensuring the safety of personnel and meeting compliance standards.
Acceptable risks are those that have been reduced to the ALARP level or considered insignificant within a broadly acceptable region. Consequently, a safety report serves as an affirmation that identified risks lie within the ALARP region and have been effectively minimised.
