Along each of these areas, auditors can gather risk and control information through interviews, facilitated sessions, surveys, document examination, analytical procedures, and observation.
It contains a clean water source tank T-8a pump P1 circulation valve, 3 valves manifold, and 1 recipient tank T The operation under control will be the transfer of water from T-8 to T We need to make sure that we identify all the relevant equipment and instruments that are involved with our process operation.
Later in the document, we will be referring to items ONLY from this list. If the process operation is generic, the tag names that will appear in the table will be generic and there will be a table to convert between the generic name and specific name for each piece of equipment in the following format.
Table 3 lists the equipment for the current process operation. To keep the water clean, storage tanks are circulated constantly through a filter F Occasionally, as process operations require, we need to transfer clean water to other locations at the site.
During a transfer we should not circulate as we want the water to be sent at the shortest time possible to the operational area.
When transferring water, only one of the manifold valves can be opened at a time in order to prevent backflow and possible contamination of the manifold and water in the main tank T During the transfer, water does not enter into the clean water main tank T There are three kinds of parameters.
The first is an external parameter. Each external parameter has two values that should be kept in historical records. The target value SP and the current value PVwhich is dynamic and changes as the process operation is executed.
The second is an internal parameter that is related only to the process operation setup. It contains information about the equipment itself. The third parameter is an internal parameter that is used only during the process execution and is not saved or monitored after the execution.
A parameter is not changeable after the process operation has started its execution. The parameters for our process are detailed in Table 4. Every alarm being generated indicates a possible problem developing, and therefore, in each case, we must define if the alarm should automatically switch the process operation execution to a HOLD state.
The methodology of defining an interlock or alarm is as follows: Interlock - corrective action by an automated control system  To prevent Describe the situation that may happen which is identified by describe the measurementTagnamein state PV for a duration longer than xx seconds set description of equipmentTagnameto SP.
The operator should verify why the filter is clogging and monitor its operation in the next 3 hours to verify that there is no problem with dirt arriving and accumulating in the T-8 tank.
The operator should verify that there is enough water in the clean water main tank, T-8, and that the process is ready to perform a transfer of the water to the clean water operational tank T-9 within the next 30 minutes.A Simple Guide to Document Control What is document control and why do we need it?
A lot of people find document control to be exceptionally tedious. We understand! However, the simple fact is that following x Is the re-approval process the same as for ini.

Document control – the process established in this procedure to define controls needed for the management of WHS&IM documentation. Records –‘ information created, received, and maintained as evidence and information by an organization or.
As many things in Document Control, it is not possible to use the same set of KPIs and statistics for all the companies and all the situations..
The reason for that is that every company has a different Document Control system (including different procedures, workflows, processes, tools, organisation and software packages).
This workbook was developed by the Centers for Disease Control and Prevention’s (CDC’s) Office on Smoking and Health (OSH) . The Committee of Sponsoring Organizations of the Treadway Commission (COSO) defines internal control as a process, effected by the board of directors, management, and other personnel, designed to provide reasonable assurance regarding the achievement of objectives.
This document describes how to write a process description (or process analysis), a variation of the short report designed to help a reader understand how a change takes place over time, through a .
