(You can then use the original set of disks to make copies for friends later on.) Next, you must install the program on a hard drive using the installation routine described below in the "For Hard Drive Users" section. This will allow the program files to uncompress and be setup for use. Then using the DOS copy command, copy all the files in the CHEMCOM subdirectory to a 3 1/2" floppy disk with the exception of the PCC1.EXE and PCC2.EXE files. (Refer to your DOS manual on how to copy files from one drive to another.) Sorry, but the floppy drive installation routine is no longer available. Due to the widespread use of hard drives and the com- plexities involved with maintaining the floppy drive installation routines, it was no longer considered worthwhile to maintain them. For Hard Drive Users: First, make a back-up copy that you can use for your working copy by using the DOS diskcopy command. (You can also use the original disk to make copies for friends then later on.) Then, using your working copy of Personal CHEMCOM, put the disk into the A: drive, then at the A> prompt type INSTALL A: C: (or B: D:) and press the Enter (Return) key. This will place the program into a separate subdirectory called CHEMCOM on your hard drive (either the C: or D: drive). STARTING THE PROGRAM -------------------- For Floppy Disk Users: Simply put Disk 1 into the floppy drive and at the DOS prompt for the drive type P_CHEMCM and press the Enter key.

DATA ENTRY ---------- Once the program starts, the first screen will ask some initializa- tion questions, such as date and time (which when dealing with plume dispersion modeling is an important factor for determining concentration and plume length), if you have a color monitor or not, and if you want your printer (preferably a dot matrix with color ribbon) to printout the results. Once past this and the title screen, you will begin to enter the actual plume release data. Before discussing the data entry, let's first review how the program is setup. It is essentially modulized as follows: 1. Meteorological data entry 2. Design Basis Accident selection 3. Elevated or ground level release data entry 4. Field sampling data entry 5. Off-centerline calculation selection 6. Plume location depiction selection Personal CHEMCOM comes with a Help routine that is noted on a screen when first going into these modules (2, 3 & 4 above start at a common module thus one Help screen is presented for them). If you would like to review the concepts behind the purpose or application of the module you're entering, you should press function key "F1". This will load the Help program. You may then select a specific topic for review or review all the material prior to going into the next data entry module. The Help routine even has a small event simulator, which steps through a basic chemical processing plant accident sequence. (Note, if you have a high speed computer the event simulator may be difficult to follow. If your machine has a turbo switch, place your machine in the slowest speed when running the event simulator. Also, at the other end of the spectrum, if you have an old, slow computer, and you try to run the event simulator, it will take forever!

A default set of values will automatically occur, but you can change them. For example: Data Requested Value Range -------------- ----------- Elevated wind direction 0 to 360 0 = North 90 = East Ground level wind direction 0 to 360 180 = South 270 = West (in degrees) (Direction wind is Elevated wind speed Breezes coming FROM) Ground level wind speed are typically (in mph) below 10 mph * Elevated stability class Three methods (Is the breeze * Ground level stability class Three methods calm or wild?) STABILITY CLASS Standard Title Selection Elev. Delta T Ground Delta T Deviation -------------------+---------------+----------------+------------ Extremely Unstable < -3.6 < -1.2 > 22.5 Moderately Unstable -3.6 to -3.2 -1.2 to -1.1 22.4 to 17.5 Slightly Unstable -3.2 to -2.9 -1.1 to -1.0 17.4 to 12.5 Neutral -2.9 to -1.0 -1.0 to -0.3 12.4 to 7.5 Slightly Stable -1.0 to 2.8 -0.3 to 1.0 7.4 to 3.8 Moderately Stable 2.8 to 7.6 1.0 to 2.5 3.7 to 2.1 Extremely Stable > 7.6 > 2.5 < 2.1 Delta T = Differential Temperature in degrees fahrenheit Standard Deviation = An average of wind direction fluctuations * Note: You only have to choose one of the three methods. The easiest of course is Title Selection. The other two methods are available for the more technically oriented. After completing the meteorological data entry section, you can then calculate chemical dose projections based on: 1. Design Basis Accident default parameters, 2. Elevated release plant meter reading inputs, 3. Ground release plant meter reading inputs, or 4. Field Monitoring Team readings. You may first choice `1' if you want to perform an initial dose assessment calculation based on plant safety analysis report design basis accident default values.

They are: 1) AHF Transfer Break (Elevated Release) 2) NH3 Transfer Break (Elevated Release) 3) AHF Tank Rupture (Ground Level Release) 4) NH3 Tank Rupture (Ground Level Release) AHF = Anhydrous Hydrogen Fluride NH3 = Ammonia Once you choose the accident type, the program will then display the chemical data associated with this accident and that will form the source term for the chemical exposure calculations. If you want to perform calculations based on actual event data, you can select from three different choices. These allow you to choose whether you want to determine the chemical release source strength based on Elevated, Ground Level or Field Monitoring parameters. You can choose one of these three, then simply enter values as prompted by the computer screens that appear. When entering data, don't use commas. For example, if you are entering a large number, it can be entered as: WRONG RIGHT ----- ----- 3.5 X 10^5 3.5E5 350,000 350000 Once you've entered all the parameters correctly or chose a design basis accident in which to base the calculations, the program will display the dose calculation results giving the downwind distances with the chemical concentrations in parts per million (ppm), recommended protective actions (based on concentrations and projection exposure time), correlated hazard levels and basic medical advice.

Specific concentrations can be categorized into industry and government accepted danger levels. They are: Value Intent -------------------------------- ------------------------------------- IDLH ÄÄ Immediately Dangerous This represents the maximum chemical to Life or Health concentration from which a person could escape within 30 minutes without receiving irreversible health effects. STEL ÄÄ Short Term Exposure This represents the maximum chemical Limit concentration a person can be exposed to for 15 minutes before sustaining abnormal health effects. TLV-TWA ÄÄ Threshold Limit This represents the maximum chemical Value-Time Weighted concentration level a person should Average be exposed to over an 8 hour period before sustaining abnormal health effects. The IDLH is utilized in CHEMCOM to determine the recommended protective action since it is based on the philosophy that the best action is one which is based on the premise of no irreversible health effects to the public. The methodology works as follows. If the downwind concentration is less than the IDLH value, then "No Action" is necessary, and thus recommended by the program. If the downwind concentration is greater than the IDLH value and the release duration is less than two and one-half hours, then "Shelter" is the recommended protective action. Finally, if the downwind concentration is greater than IDLH and the release duration is greater than two and one-half hours, then "Evacuate" is the recommended protective action. Note: Two and one-half hours is used instead of 30 minutes, since it is presumed that if a person shelters, it takes approxi- mately two hours before the air inside the shelter is at the concentration of the air outside the shelter. (from studies) Page 5 of 8 ÉÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ» º PERSONAL CHEMCOM OPERATIONS MANUAL º ÈÍÍÍÍÍÍÍËÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍËÍÍÍÍÍÍͼ º FOR SHAREWARE DISK º ÈÍÍÍÍÍËÍÍÍÍÍÍÍÍËÍÍÍÍͼ º Cont'd º ÈÍÍÍÍÍÍÍͼ DATA ENTRY (Cont'd) ------------------- After evaluating your final results screen, the program then asks you if you want to calculate off-centerline readings. What this pertains to is the chemical levels of the plume as it spreads out or widens. The concentrations given in the final results were based on plume centerline or the area of the highest chemical dose rates. However, as the plume (or toxic cloud) moves along in the breeze it is diluted and tends to spread out and thus the chemical levels in these portions of the plume are lower than the centerline readings. That is what this portion of the program calculates. This is important to the decision-makers during a hazardous chemical emergency, since it enables them to see what areas will be affected with high doses of chemicals; and thus, how many adjacent communities may have to be sheltered or evacuated. If you say "N" or no to performing off-centerline calculations or if you've completed them, the next thing the program asks you is if you want to display the plume location. If you say "N" or no to this, the program will then ask you if you want to stop (exit the program) or do a recalculation using new parameters. If you say "Y" or yes, then you will be asked to enter the time when the chemical release started. Normally, if this were a real emergency or a controlled simulation, the release start time may be one to two hours before you started this computer session or slightly after you started. This is mainly because if no release of chemicals is occurring or is ready to occur then there would be no emergency and no need to use this program. So if you logged into the program initially at 9:00 am say, then you could enter a release start time in a range of around 7:00 to 11:00 am. If you logged into the program at 2:00 pm, then a range of about 12:00 to 4:00 pm would be logical. To enter a time figure at this point it has to be in the military format. For example, if you were entering 7:00 am, you would simply type 7:00 and press the Enter key. If you were entering 1:00 pm, then you would have to type 13:00 and press Enter. Proper entry of the release start time at this point is important because the computer will use this time, along with the current time, and the wind speed (entered in a previous module) to determine how far out the plume has traveled and how long it is.

If you say "S" or stop, then you exit the program and go to DOS. If you say "R" for recalculation, then you will be permitted the chance to go back through the program and change any of the entry parameters.
