Where to apply RAST – Risk Analysis Screening Tool?

RAST can be used for new projects, for comparing between inherently safer designs, for evaluating changes to existing processes (i.e., Management of Change, MOC), and during incident investigations (i.e., help identify other potentially unrecognized hazardous scenarios). In addition to providing more quantitative assessments during a Process Hazard Analysis (PHAs), specific scenarios can be prioritized for use in a Layer of Protection Analysis (LOPA). RAST is ideal for small and mid-sized companies that may not have the complex, daunting, and expensive analytical tools available within their company. With RAST, these companies have an analytical tool to help them screen for their worst case scenarios and associated risks in such way that they can prioritize, develop and implement approaches to help improve their overall process safety performance.

Duiding:

RAST assists with hazard identification, scenario development, consequence evaluation, and risk analysis. Starting at the level of equipment or activity, the Excel tool identifies chemical and process hazards. Then it determines what can go wrong by developing scenarios, how bad it could be by analysing consequences and how often it might happen by estimating frequencies. Subsequently, risk tolerance is determined and where needed additional safeguards can be implemented. RAST is supported by a free 126 page user manual and an Excel based CHEF calculation aid.
