Seven Attributes of RISK ASSESSMENT MATRIXES

A third is measuring risk level prior to and after a safety-related activity, and a fourth is supporting decisions about acceptability of residual risks (Ale et al, 2015; Baybutt, 2018; Main, 2020). In high-risk industries such as nuclear power, aviation, space travel, deep-sea exploration and many...

Summary:A third is measuring risk level prior to and after a safety-related activity, and a fourth is supporting decisions about acceptability of residual risks (Ale et al, 2015; Baybutt, 2018; Main, 2020). In high-risk industries such as nuclear power, aviation, space travel, deep-sea exploration and many industrial plants processing highly hazardous chemicals, Equation la is used. Because of the importance of having accurate probability values, these are sometimes referred to as probabilistic risk assessments (Bahr, 2015; Modarres, 2006). Organizations that sell products to the U.S. Department of Defense may feel compelled to use a matrix specified in the procurement materials such as the one for system safety programs in Figure 4. If estimates of severity and likelihood are rather crude, there is no sense expecting people to reliably distinguish adjacent cells having small differences in their row and column categories.
