Site Status Notification

In the event of contingencies, such as winter storms, wildfires, and power outages, NIST may find it necessary to restrict access to facilities to ensure the safety and well-being of personnel and to expedite site recovery. 

NIST will provide notice to employees and associates through a variety of means including GovDelivery ENS notifications using text and e-mail, messages on the NIST Status line, and notices via social media. NIST encourages all staff to subscribe to e-mail and text alerts. 

NIST employs various levels of closure depending on the campus conditions. Below is an outline of those levels that you may hear when receiving Gov Delivery text/e-mail notifications or looking at social media. 

Site is Closed - NO ACCESS [Emergency Event]

  • The site is closed for onsite business and no public access is permitted; previously approved accesses are revoked.
  • Access will be granted to designated emergency response officials under NIST/NOAA/NTIA and DOC (Department of Commerce), as well as other local, state and federal emergency incident responders.
  • Employees/associates (facility users) are NOT permitted access, UNLESS APPROVED BY the Emergency Services Office (ESO) director.
