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.
Risk assessment is part of the core elements of risk management defined in ISO 31000, which are: . communication and consultation; establishing the context; risk assessment (risk identification, risk analysis, risk evaluation)
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.
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 ...
The PHA is in turn based on a hazard identification exercise. In the process industries (oil and gas production, refineries, chemical plants, etc.), this exercise is usually a hazard and operability study (HAZOP). The HAZOP usually identifies not only the process hazards of a plant (such as release of hazardous materials due to the process ...
