2. Hazard analysis - Wikipedia

   en.wikipedia.org/wiki/Hazard_analysis

   When used as part of an aviation hazard analysis, a "Likelihood" is a specific probability. It is the joint probability of a hazard occurring, that hazard causing or contributing to an aircraft accident or incident, and the resulting degree of loss or harm falling within one of the defined severity categories.

3. Occupational risk assessment - Wikipedia

   en.wikipedia.org/wiki/Occupational_risk_assessment

   An occupational risk assessment is an evaluation of how much potential danger a hazard can have to a person in a workplace environment. The assessment takes into account possible scenarios in addition to the probability of their occurrence, and the results. [ 1 ]

4. Layers of protection analysis - Wikipedia

   en.wikipedia.org/wiki/Layers_of_protection_analysis

   Layers of protection analysis (LOPA) is a technique for evaluating the hazards, risks and layers of protection associated with a system, such as a chemical process plant. . In terms of complexity and rigour LOPA lies between qualitative techniques such as hazard and operability studies (HAZOP) and quantitative techniques such as fault trees and event trees.

5. Process hazard analysis - Wikipedia

   en.wikipedia.org/wiki/Process_Hazard_Analysis

   A simple element of risk quantification is often introduced in the form of a risk matrix, as in preliminary hazard analysis (PreHA). The selection of the methodology to be used depends on a number of factors, including the complexity of the process, the length of time a process has been in operation and if a PHA has been conducted on the ...

6. Structured what-if technique - Wikipedia

   en.wikipedia.org/wiki/Structured_what-if_technique

   The structured what-if technique (SWIFT) is a prospective hazards analysis method that uses structured brainstorming with guidewords and prompts to identify risks, [1] with the aim of being quicker than more intensive methods like failure mode and effects analysis (FMEA). [2] [3] It is used in various settings, including healthcare. [1] [2] [3] [4]

7. Risk assessment - Wikipedia

   en.wikipedia.org/wiki/Risk_assessment

   Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [2]

8. Hazard analysis and critical control points - Wikipedia

   en.wikipedia.org/wiki/Hazard_analysis_and...

   Hazard analysis and critical control points, or HACCP (/ ˈ h æ s ʌ p / [1]), is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe and designs measures to reduce these risks to a safe level. In this manner, HACCP attempts to ...

9. Hazard and operability study - Wikipedia

   en.wikipedia.org/wiki/Hazard_and_operability_study

   A hazard and operability study (HAZOP) is a structured and systematic examination of a complex system, usually a process facility, in order to identify hazards to personnel, equipment or the environment, as well as operability problems that could affect operations efficiency.
