User's Reference Model Safety Assessment for Explosives Risk (SAFER) Risk Analysis Software
Abstract
The Safety Assessment for Explosives Risk (SAFER) model was developed to provide a more comprehensive assessment of the overall risk associated with explosives operations and storage. This evaluation involves determining the required Quantity-Distance separation distance based on the relationship between the Potential Explosion Site (PES)/Exposed Site (ES) pair, type of operations (or storage) being conducted in each facility, and the type and quantity of explosives involved. Acceptability is based on comparison of the actual separation distance to the required separation distance. The evaluation is performed independently of all other PESs and ESs involved in the overall siting scenario. Risk-based analysis is exciting in that it allows users to quantify risk and validate their common-sense knowledge that some siting scenarios present more risk than others. Performing risk-based siting can be a complex process. Adding a single PES or ES to an area with multiple PESs and ESs can cause a ripple effect on the overall risk profile. The SAFER model calculates risk in terms of the statistical expectation for loss of life from an explosives event. Three components are multiplied to estimate annual maximum probability of fatality, P(f), and the expected fatalities, E(f): (1) the probability of an explosives event, P(e), (2) the probability of a fatality given an event, P(f/e), and (3) the average exposure of an individual, E(p).
