Hazards Analysis System/Node Records

Hazards Analysis System/Node records store details on the group of equipment or functional locations that perform the process that you are studying. This topic provides an alphabetical list and description of the fields that exist for the Hazards Analysis System/Node family. These fields appear on the Hazards Analysis System/Node datasheet, unless otherwise specified. The information in the table reflects the baseline state and behavior of these fields.

This family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. See the Site Filtering section of the documentation for more information on using this feature.
