The perimeter of a specific manufacturing process area. It is often defined by the roads around the perimeter. This area will include process equipment, and may include in-process tankage.
Sometimes called batch instruction. The operating procedure for making a batch product. Primarily focuses on material quantities, as well as instructions for any mixing, reaction, heating, cooling, drying required for the process.
Reactor in which all reactants and solvents are introduced prior to setting the reaction conditions (temperature, pressure). Products are only taken from the reactor upon conclusion of the reaction process. Both heat generation and concentrations in the batch reactor vary during the reaction...
A system that responds to input signals from the process and its associated equipment, other programmable systems, and/or from an operator, and generates output signals causing the process and its associated equipment to operate in the desired manner and within normal production limits.
An event in a fault tree that represents the lowest level of resolution in the model such that no further development is necessary (e.g., equipment item failure, human failure, or external event).
a process to characterize the current and potential threats to human health and the environment that may be posed by contaminants migrating to groundwater or surface water; releasing to air; leaching through soil; remaining in the soil and bio-accumulating in the food chain. The primary purpose of...
A control measure or grouping of control elements that on its own can prevent a threat developing into a top event (prevention barrier) or can mitigate the consequences of a top event once it has occurred (mitigation barrier). A barrier must be effective, independent, and auditable.
A management system that provides feedback on both internal business processes and external outcomes to continuously improve strategic performance and results.
There are three Average Individual Risks; 1) Average Individual Risk (exposed population) is the individual risk averaged over the population which is exposed to risk from the facility, 2) Average Individual Risk (total population) is the individual risk averaged over a predetermined population,...
