an analysis, conducted by a team of people with varying backgrounds and expertise, that focuses on specific parts of a process, called nodes, to identify hazards and operability problems. For each node, process parameters, intentions (using accompanying guidewords), and deviations are identified. Next, consequences of deviations are examined and safeguards and other appropriate recommendations are suggested. Hazards are defined as operations that could cause the release of toxic, flammable, or explosive chemicals; or any other action that could result in injury to personnel. An operability problem is any operation within the design envelope that could result in a viloation of environmental, health, or saftey regulations and/or cause a shutdown that would negatively impact profitablity.
