5. Example Applications

These example applications are for training purposes only and are not intended to apply to any real world situation.

"HAPEM (1 chem)" - This package provides instructions for setting up and running an example application where HAPEM calculates inhalation exposure estimates for a single chemical.

Step 1. - If TRIM has not been previously installed, install it using the TRIM Installer. Be sure to select "Inhalation Exposure Assessment with HAPEM" when prompted to "Please select the activities you expect to perform with TRIM."

Step 2. - Download HAPEM and accompanying input files from Section #3 (Software Available for Download) above.

Step 3. - Confirm that the Human Toxicity Value Database is currently installed on your computer. To do this, go to the "MySQL Server 4.x\data" subdirectory of the MySQL directory on your computer (e.g., C:\Program Files\MySQL\MySQL Server 4.1\data) and check to see if the "HHToxDB" directory exists. If so, the Human Toxicity Value Database is installed. If you have not previously installed this database, download it from the TRIM.Risk Download page and follow the instructions for installing it.

Step 4. - Confirm that the HAPEM Census Tract Database is currently installed on your computer. To do this, go to the "MySQL Server 4.x\data" subdirectory of the MySQL directory on your computer (e.g., C:\Program Files\MySQL\MySQL Server 4.1\data) and check to see if the "hapem_countyinfo_2000" directory exists. If so, the HAPEM Census Tract Database is installed. If you have not previously installed this database, download it from Section #4 (Input Data) above and follow the instructions for installing it.

Step 5. - Download "HAPEM (1 chem)" example application instructions. Print this file and follow the directions.

"HAPEM (>1 chem)" - This package provides instructions for setting up and running an example application where HAPEM calculates inhalation exposure estimates for multiple chemicals.

Step 1. - If TRIM has not been previously installed, install it using the TRIM Installer. Be sure to select "Inhalation Exposure Assessment with HAPEM" when prompted to "Please select the activities you expect to perform with TRIM."

Step 2. - Download HAPEM and accompanying input files from Section #3 (Software Available for Download) above.

Step 3. - Download the ZIP package HAPEM (>1 chem) Example Application (zip) (21.81 MB) .

Step 4. - Unzip ExampleApp_HAPEM_Multi.zip into the "input" subdirectory of your HAPEM directory (e.g., C:\HAPEM\input). Be sure to maintain the directory structure of the files being unzipped. This is done by default with WinZip's Wizard interface, and is done by checking the "Use folder names" box in the Extract screen of WinZip's Classic interface.

This ZIP file contains the following five files: con43218.txt
con43301.txt
con43367.txt
con43370.txt

Step 5. - Confirm that the Human Toxicity Value Database is currently installed on your computer. To do this, go to the "MySQL Server 4.x\data" subdirectory of the MySQL directory on your computer (e.g., C:\Program Files\MySQL\MySQL Server 4.1\data) and check to see if the "HHToxDB" directory exists. If so, the Human Toxicity Value Database is installed. If you have not previously installed this database, download it from the TRIM.Risk Download page and follow the instructions for installing it.

Step 6. - Confirm that the HAPEM Census Tract Database is currently installed on your computer. To do this, go to the "MySQL Server 4.x\data" subdirectory of the MySQL directory on your computer (e.g., C:\Program Files\MySQL\MySQL Server 4.1\data) and check to see if the "hapem_countyinfo_2000" directory exists. If so, the HAPEM Census Tract Database is installed. If you have not previously installed this database, download it from Section #4 above and follow the instructions for installing it.

Step 7. - Print the StepsForHAPEM_Multi_ExampleApp.pdf (unzipped in Step 4) and follow its steps.
