FAILURE CONSEQUENCES AND SEVERITY Slide No. Introduction Failure consequences are the results of the action or process of failure. They are outcomes or effects of failure as a logical result or conclusion. A consequence can be defined as the results of a failure e.g. gas cloud fire explosion evacuations injuries deaths public and employee health effects environment damages or damage to the facility. CHAPTER 5a. FAILURE CONSEQUENCES AND SEVERITY Slide No. Introduction Failure severity is the quality condition strictness impact harshness gravity or intensity of failure consequences. The amounts of damage that is or that may be inflicted by a loss or catastrophe constitute the severities. The severity cannot be assessed with certainty and is desired in monetary terms. CHAPTER 5a. FAILURE CONSEQUENCES AND SEVERITY Slide No. Introduction The failure of an engineering system could lead to consequences creating a need to assess failure consequences and severities The assessment methods can be based on 1. Analytical models such as microeconomic techniques and 2. Data collection from sources that include accident reports. CHAPTER 5a. FAILURE CONSEQUENCES AND SEVERITY Slide No. Introduction Severity uncertainty has been recognized in the insurance industry and treated using random variable or stochastic-process representations. Also terms such as the maximum possible loss MPL and the probable maximum loss PML are used. They are assessed as the worst loss that could occur based on the worst possible combination of circumstances and the loss that is likely based on the most likely combination of circumstances respectively.
