Access and security
Site access depends on authorization by your organization and on the instructions for the specific site. This guide explains the general concepts. Follow the applicable adopted requirements and their precedence provisions. Visitor pages explain preparation but do not amend those requirements; refer conflicts to the authorized contact before the affected activity proceeds.
Authorization and appointments
Your administrator authorizes who may access a site. Visits generally require an appointment or an active credential, depending on the site and the person's role.
Preparing to arrive
- Confirm your authorization and appointment before travel
- Bring the identification described on the acceptable ID page
- Review the site instructions for escorts, photography, and restricted areas
Identity information
Share identity documents only through the approved verification process. Do not send identification by email or support ticket, and never share access credentials or PINs with anyone.
