Clarity:

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.
