A process hazard analysis (PHA) (or process hazard evaluation) is an exercise for the identification of hazards of a process facility and the qualitative or semi-quantitative assessment of the associated risk. A PHA provides information intended to assist managers and employees in making decisions for improving safety and reducing the ...
Failure mode and effects analysis ( FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system ...
A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
Extended matching items/questions ( EMI or EMQ) are a written examination format similar to multiple choice questions but with one key difference, that they test knowledge in a far more applied, in depth, sense. It is often used in medical education and other healthcare subject areas to test diagnostic reasoning .
A hazard analysis is one of many methods that may be used to assess risk. At its core, the process entails describing a system object (such as a person or machine) that intends to conduct some activity. During the performance of that activity, an adverse event (referred to as a “ factor ”) may be encountered that could cause or contribute ...
Fred Trump III, the nephew of former President Donald Trump, said his uncle is "atomic crazy," that he witnessed him using racial slurs decades ago -- and that he plans to vote for Kamala Harris.
A double-barreled question (sometimes, double-direct question [1]) is an informal fallacy. It is committed when someone asks a question that touches upon more than one issue, yet allows only for one answer. [2] [3] [4] This may result in inaccuracies in the attitudes being measured for the question, as the respondent can answer only one of the ...
A cyber PHA or cyber HAZOP is a safety-oriented methodology to conduct a cybersecurity risk assessment for an industrial control system (ICS) or safety instrumented system (SIS). It is a systematic, consequence-driven approach that is based upon industry standards such as ISA 62443-3-2, ISA TR84.00.09, ISO/IEC 27005:2018, ISO 31000:2009 and ...
