OPERATING PROCEDURE FOR THE CEI2 SYSTEM - VERSION 2.0
INTRODUCTION
The CEI2 System helps prepare Chemical Exposure Index Calculations based on the New CEI Methodology utilized in the "CHEMICAL EXPOSURE INDEX GUIDE", 2nd Edition, issued in September 1993. The CEI2 System is comprised of EXCEL spreadsheets and macros and features fully automated, menu-driven operation with extensive on-line help. Full cases results as well as the CEI Summary Form are output in the designated format.
VER 2.0 - NOTE REQUIREMENT
Due to significant changes, Ver-1.0 Work Files CANNOT be processed using the CEI2 Ver-2.0.
The CEI2 System runs on a DOS-based computer running Microsoft Windows and requires at least Microsoft EXCEL Version-4.0.
INSTALLATION USING THE SYSTEM
WARNINGS
CHANGE MANAGEMENT
The CEI2 System is located on the Midland USPWS4 Fileserver as: DOWSLPS Spredsht CEI2 CEI2_DEN (DOS English units) CEI2DSI (DOS SI units)
Copy the desired folder/directory to your computer hard drive from the Fileserver as well as Operating Procedure and Management of Change documentation.
1. Double-click on the file named 'CEI2.XLS' in the downloaded directory/folder. Note the ".xls" extension may not appear depending on the options you have chosen under "View" in the Menu Bar.
2. This opens the required files and starts the CEI2 System, 3. Use the CEI2 Menu to navigate through the CEI2 System and refer
to the On-line Help for additional information. 4. The CEI2 System employs the 'Cases Concept'; hence, data in a case
column (in blue) may be changed at any time, prior to performing the calculations. 5. Printing of the Cases File and CEI Summary Form for a desired case is through EXCEL's 'Print-Preview' to allow flexibility in page set-up and printer selection. 6. Quit the CEI2 System using the CEI2 Menu upon completion.
1. The CEI2 Menu MUST BE used for ALL data input and file opening, saving and closing.
2. A Work File MUST BE opened and processed through the CEI2 System to make changes and for proper operation.
3. Double-clicking on a Work File DOES NOT start the CEI2 System. 4. NONE of the CEI2 files EXCEPT the user Work File MUST BE
CLOSED BEFORE EXITING the CEI2 System!
The management of change form must be used to initiate changes to the CEI2 System and directed to Norm Scheffler, Process Safety Services, 2030 Building.

Tips for using the CEI Spreadsheet. Version 2.0
1) Spreadsheets generated with version 1.0 of the CEI Spreadsheet can not be updated with version 2.0 of the CEI spreadsheet. You must go back to version 1.0 or re-enter the data in the new version 2.0.
2) AH data entry should occur in the CEI2.XLS file, not the workfile that you create and name. The data entered into the CEI2.XLS file is saved to your workfile as calculations are completed.
3) When entering system inventory data, be sure that there is sufficient inventory for at least a 5 minute release, especially for a gas pipeline release. The CEI calculations do not allow credit for block valves to automatically shutoff and terminate a gas release.
4) When entering hole diameter for a liquid release scenario, use the PIPE diameter. The spreadsheet automatically calculates the hole size based on PIPE size and CEI guideline rules.
5) When entering hole diameter for a gas release scenario, you must determine the HOLE diameter as specified by the CEI guidelines first. The spreadsheet does NOT automatically calculate the hole size.
6) Any adjustments to the operating temperature must be made through the CEI menu, NOT as an entry on the spreadsheet. The physical properties will not recalculate if operating temperature is changed via a direct spreadsheet entry.
7) For some compounds, the physical properties are NOT temperature compensated. Butadiene is a known example of this. If you specify an operating temperature other than that corresponding to the CEI database, the physical property data should be gathered and manually entered.
8) For some compounds, the physical property data prediction algorithms have a limited temperature range. You will get an error message. Again, data should be gathered and manually entered for these situations. An example is anhydrous HCL at low temperature (heat capacities come out negative!).
9) The CEI summary form (the sheet which summarizes the CEI and hazard distances and also has space for signatures) that is generated from the workfile after calculations are complete does not print out correctly. Attempts to reformat the document to produce a useable printout were unsuccessful. If you can't get a good printout, make a copy of the file called CEI Form.doc and manually transfer your data into that document.
10) If you get a "halt, step, continue" error message when saving the work file, you may lose all your data if you "step or continue" through the process. Select "halt" to stop the process. Hopefully, you have saved your work as you went along so that you won't lose anything or lose very little. You then need to close all files by: a) quitting the CEI System (close, not minimize!) and b) closing EXCEL (hidden files will come up that need to be closed).
