(41ap) Aspects of Application of Hazard Identification and Risk Analysis in Mining and Metal Operations

Mining and Metals industry differs from the chemical process industries in essence and for that reason process safety management should have and different specific approach to be adressed. The mining and metals industry defines the catastrophic event scenarios of its operations as Material Unwanted Events (MUE) es established in the International Council on Mining and Metals standard. This definition aims to standardize the categorize of these scenarios and thus allow different activities in the mining area to establish performance and comparison criteria. Another important objective is to help prioritize these scenarios to be studied and appropriate risk management actions defined. This paper aims to present DSS experience so far, in adressing specifically the process hazard analysis that the mining and metals industry use to call hazard identification and risk analysis (HIRA). Process Hazard Analysis is one of the 22 elements of the Risk Based Process Safety (RBPS) system developed and developed by the AIChE/CCPS.
