Operating Parameter Information Each operator performing the normal operating procedures (routine checks) of the facility should be familiar with the current normal operating parameters of all systems on the facility. This will enable the operator to identify when an adjustment or shutdown may be necessary. Some of the resources available to the Operator for this purpose include: Prior observations of parameters such as levels and temperatures The knowledge of others who are experienced with this facility A copy of the most recent Monthly Safety Devices Inspection and Maintenance Record (Monthly Testing Report) Safety Analysis and Function Evaluation (SAFE) Charts to identify safety device protected parameters When performing routine checks, operators should be able to evaluate all observable parameters to determine whether they are normal, troubleshooting is necessary or a shutdown is required. As the operator identifies that parameters are within normal ranges, no action is necessary. However, should the operator find that the parameter is beyond the normal range, but still within the safety device set point, troubleshooting could be required. The following list is a general overview of the preliminary actions an operator can take to determine the correct course of action for a parameter that has gone beyond the normal range but not yet reached the shutdown setting: An operator can monitor the parameter to see if it returns to normal. The outof-range parameter may be the result of a short-term fluctuation in incoming flow characteristics. (i.e. a momentary fluid surge) An operator can verify the settings of control loops/devices to verify they are set correctly. (i.e. a back-pressure valve setting may require adjustment) Once an operator has verified that the parameter is consistently outside the normal operating range as the result of an acceptable change in incoming flow characteristics, it may be necessary to establish a new normal operating range. An operator may seek the experience of other operators or supervisors in determining the cause for the abnormal parameter. An operator may determine it is necessary to perform shutdown procedures before the safety device setting if the parameter is increasing or decreasing at a rate too quickly to troubleshoot.

Parameters with unacceptable consequences for deviation are identified according to regulatory guidelines employed during the design process. Safety devices are installed in one or more components of the production train (process system) to prevent those deviations and their subsequent consequences. The following charts can be used to assist an operator in troubleshooting and correcting potential deviations before a shutdown is necessary. NOTICE: Safety devices are set to perform automatic shutdowns of the facility processes when the operating parameters go beyond the troubleshooting zone. Any operation of the facility while a parameter is beyond the troubleshooting zone is considered Emergency Operations. As stated in Section 1, the facility will not be operated under emergency conditions. Any operator finding a parameter beyond the safety device setting should assume that the safety device has failed and immediately initiate a shutdown of the system or, if necessary, the entire facility process.
