A site could for example be the location of the HQ and the different manufacturing plants that your organization has across the world. The sites will be stored in RAYVN, and when you start a log, you will be asked to specify where the location of the incident is. Note that you can create as many sites as you want in RAYVN. 

To manage the Sites go to the Account settings, and click "Sites."

To create a new site, click "+ Create new site".

Type in the name of the site and use the map to find the location. You can also assign the site to a group. For physical sites, you should also add the location by entering the address, or by entering GPS coordinates.

Press Save and the location will be listed in Sites. Repeat the process if you are creating more sites.
