NNSS Mandatory COVID-19 Safety Protocols

As a result of the COVID-19 pandemic, the NNSS has implemented several mandatory safety protocols to protect both the workforce and approved visitors, subcontractors, vendors, etc. (Please note: NNSS public tours remain on hold.) In addition to compliance with normal NNSS safety and security protocols, all approved visitors, subcontractors, vendors must also comply with the mandatory COVID protocols for the site.

Due to the rapidly changing environment, COVID protocols are subject to change and should be reviewed frequently and/or prior to every visit. Failure to abide by any safety or security protocols, including COVID protocols, can lead to denial of access and/or your immediate removal from the site.

COVID protocols include:

  • Stay home if you are sick or have been in close contact with someone who is sick.
    • Perform a symptom check prior to coming to work or entering any NNSS facility. If you are experiencing fever, cough, shortness of breath, fatigue, aches/pains, diarrhea, chills, repeated shaking with chills, vomiting, sore throat or sudden loss of taste or smell, stay at home or immediately go home.
  • Practice six-foot social distancing.
  • Wear a face covering.
    • Individuals who are not fully vaccinated may remove masks when alone in an office with floor-to-ceiling walls and the door shut. Individuals who are fully vaccinated may remove face coverings when alone in separate enclosed offices or in workspaces when they are not in close contact with others.
    • Individuals working in spaces in which they are in close contact through proximity and duration of exposure (e.g., within six feet of another individual for a cumulative total of 15 minutes or more over a 24-hour period) must wear a face covering while in those spaces.
    • Face coverings are to be worn when employees are in shared vehicles. Single vehicle occupants need not wear a face covering during entry/exit badge checks, but should be prepared to wear one during vehicle inspections or as requested by a Security Police Officer.
    • Face coverings can be removed when eating and/or drinking or while in outdoor spaces when maintaining six feet of physical distancing.
    • Face shields worn without the use of a face covering are not approved alternatives to face covers unless authorized as a non-restrictive alternative as a medical, disability, safety or specific-use accommodation.
  • Cover your coughs and sneezes.
  • Wash your hands frequently.
  • Avoid physical contact with others, such as shaking hands.
