There are two versions of SafetyHAT available for download. The Microsoft Access Template Version is intended for individuals who plan on regularly using SafetyHAT and have Microsoft Access 2010 or later. The Microsoft Access Runtime Version is an evaluation version intended for users without Microsoft Access 2010 or later.
- MS Access Template Version (10MB): This version provides a reusable SafetyHAT template for Microsoft Access 2010 or later. You will be able to evaluate multiple systems using STPA by creating new instances of SafetyHAT directly from MS Access. This version allows the user to view or edit the underlying data tables, or database structure.

How to Use MD5 Checksum to Validate the Integrity of a Downloaded File
Whenever you download files from the internet, it is important to verify that the file you are downloading IS in fact the file that you wanted to download – that is, nobody has modified it in any way.
You can do this by calculating the MD5 checksum of the file that you downloaded and comparing it to the one we’ve provided below the download link. There are many tools and resources available online to assist you with doing this. We used the File Checksum Integrity Verifier (FCIV) utility from Microsoft.
You can download FCIV for free here.
If the checksum values do not match, someone may have modified the contents of the file – if this is the case, do not run the application and report the problem to SafetyHAT@dot.gov so that we can investigate.
