Hansom Air Force Base has declared Force Protection Condition Bravo.


Laboratory response to COVID-19

MIT Lincoln Laboratory is closely monitoring the COVID-19 pandemic and will communicate the appropriate responses, adapt Laboratory policies as needed, and provide resources for the Laboratory community to stay safe. This is a rapidly evolving situation and protecting the health and safety of the MIT community is paramount. We encourage employees to continue to visit the COVID-19 Pandemic website on our intranet.

All employees who are able to work remotely should do so, in coordination with their supervisors. All personnel working at the Laboratory are asked to practice social distancing and follow best practices for preventing the spread of germs. 

Meetings, conferences, and events have been cancelled, postponed, or are being held via tele- or video-conferencing. All outside events and activities scheduled to use Lincoln Laboratory facilities have been cancelled. All nonessential business travel has been cancelled.  

MIT Lincoln Laboratory was declared essential for national security and remained open during the Commonwealth of Massachusetts shutdown, originally initiated on March 23, of non-essential businesses. The official Air Force designation is available here.

COVID-19 control and prevention protocols

Lincoln Laboratory complies with Centers for Disease Control and Prevention, Department of Defense, and Commonwealth of Massachusetts guidance on infection control and prevention. We expect our employees, visitors, and contractors to comply with this guidance.

The Laboratory requires social distancing (six feet or more) at all times for anything but fleeting contact, and requires wearing a face covering while in common spaces including restrooms, hallways, and the cafeteria; and in work or meeting rooms where there is more than one person present.

The Laboratory has taken aggressive steps to enhance workplace sanitization, including frequent wipe-down of commonly touched surfaces, increased custodial services, disinfection of common spaces twice daily plus weekends, and distribution of supplies to areas throughout the facility. Meeting leaders are instructed to wipe down all high-touch surfaces in conference rooms before and after their meetings. 

Lincoln Laboratory conducts internal contact tracing if (a) an employee tests positive, (b) an employee exhibits COVID-19 symptoms, or (c) an employee has had close contact with others and is unwell. Contact tracing identifies people, facilities, and parts/materials that may have been exposed to the coronavirus. All close contacts are asked to self-isolate, and all identified rooms, areas, and materials used by the ill person are sanitized or isolated as appropriate.

Laboratory field sites

Lincoln Laboratory’s priority is protecting the health and safety of all employees. Personnel at all field sites and offices staffed by Laboratory personnel should follow the advisories and directives issued to Laboratory personnel in Massachusetts and available at the COVID-19 Pandemic website on our intranet. Also, personnel at field sites and offices should monitor the guidance and policies provided by public health agencies of the states in which they are located.

Visitor information

Visitors to the Laboratory are being limited as a precaution against increased COVID-19 transmission across the state and the country.

Effective 22 September 2020, only authorized visitors who have a valid COVID Visitor Pass will be able to enter Laboratory facilities. Visitors may access the COVID Visitor Pass app via The COVID Visitor Pass is good until midnight and requires an initial acknowledgement of compliance to access the Laboratory and a daily health attestation. Please see the user guide for more information. 

The paper self-attestation form will be available to visitors, if required.  Visitors may bring a completed copy of the Visitor Screening Questionnaire with them (completed no more than 24 hours prior to their visit) or can complete the form on site.

Visitors to Lincoln Laboratory will be allowed access to the facility for business purposes only and must comply with Laboratory policies while at our facility, including current policies regarding the use of face masks and social distancing.

Visitors to the Laboratory must also comply with the Commonwealth of Massachusetts COVID-19 Travel Advisory, effective March 22, 2021. The advisory states that all visitors entering Massachusetts, including returning residents, are advised to quarantine for 10 days upon their arrival.  Travelers in the following categories are exempt from this quarantine advisory:

  • Travelers who have received a negative COVID-19 result on a test administered not more than 72 hours prior to their arrival in Massachusetts. Travelers may also test out of the quarantine advisory after arrival in Massachusetts, as long as they quarantine until receiving a negative test result.
  • Anyone who is entering Massachusetts for fewer than 24 hours.
  • Anyone who is returning to Massachusetts after being out of the State for fewer than 24 hours.
  • Workers who enter Massachusetts to perform critical infrastructure functions (as specified by the Federal Cybersecurity and Infrastructure Security Agency) during required commuting to or from work and while at work.
  • Travelers who are fully vaccinated (i.e. who have received two doses of either the Moderna or Pfizer COVID-19 vaccines OR who have received a single dose of the Johnson & Johnson vaccine, 14 days or more ago) and who do not have symptoms.

Note that visitors providing support to the Laboratory or any other member of the Defense Industrial Base fall under the exemption for "Workers Providing Critical Infrastructure Services" and may visit Lincoln Laboratory without first producing a negative test result or completing a 10-day quarantine. Additional information may be found here:


The Cybersecurity & Infrastructure Security Agency (CISA) specifies the DIB as:

  • Workers who support the essential services required to meet national security commitments to the federal government and U.S. Military, including, but are not limited to, space and aerospace workers, nuclear matters workers, mechanical and software engineers (various disciplines), manufacturing and production workers, IT support, security staff, security personnel, intelligence support, aircraft and weapon system mechanics and maintainers, and sanitary workers who maintain the hygienic viability of necessary facilities.
  • Personnel working for companies, and their subcontractors, who perform under contract or sub-contract to the Department of Defense (DoD) and the Department of Energy (DoE) (on nuclear matters), as well as personnel at government owned/government operated and government-owned/contractor operated facilities, and who provide materials and services to DoE (on nuclear matters) and the DoD, including support for weapon systems, software systems and cybersecurity, defense and intelligence communications, surveillance, sale of U.S. defense articles and services for export to foreign allies and partners (as authorized by the U.S. government), and space systems and other activities in support of our military, intelligence, and space forces. 

Medical information

When and how you should self-report

The Laboratory is following CDC and state guidance for when you should self-report possible exposure to the coronavirus. Guidance will likely evolve (see CDC website for the most up-to-date guidance), but these are the current recommendations for when and how to report:

If you (or a member of your household) are experiencing COVID-19-like symptoms (fever or feeling feverish, sore throat, new cough not related to a chronic condition, new nasal congestion or new runny nose not related to seasonal allergies, muscle aches, new loss of smell, shortness of breath), you should

  • Stay at home* and self-isolate until advised otherwise
  • Self-report to [email protected] and wait for reply
  • Use the MIT COVID Pass Self-Attestation App to report any symptoms
  • If your medical provider is not MIT Medical, contact your medical provider for guidance

If you have traveled via commercial transit in the last 14 days OR arrived in Massachusetts from a state not on the MA exempt list (not part of normal commute, and not just a day trip) OR have had close, sustained contact with a person diagnosed (confirmed or presumptive**) with COVID-19, you should

  • Stay at home* and self-isolate until advised otherwise
  • Self-report to [email protected] and wait for reply
  • Use the MIT COVID Pass Self-Attestation App to report any symptoms
  • Notify supervisor via email or phone
  • Work remotely, if possible

If you are feeling sick, but the symptoms do not align with COVID-19 (e.g., symptoms indicate a sore throat or cold), you should

  • Stay at home* and self-isolate until advised otherwise
  • Self-report to [email protected] and wait for reply
  • Notify supervisor via email or phone
  • Work remotely, if possible

If you (or a member of your household) have had fleeting contact with a person diagnosed (confirmed or presumptive**) with COVID-19, you should

  • Be aware that self-reporting and self-isolation are not required
  • Work remotely, if possible
  • Continue self-observation (remain alert for symptoms) and practice social distancing

*If at work when symptoms begin, notify your supervisor via phone or email and leave the Lab immediately.
**A presumptive diagnosis is an initial positive test for the virus by a public health lab that has not been confirmed by the CDC.

Additional guidance from MIT Medical

Self-isolation / medical quarantine

If you meet the criteria for self-reporting, you should follow all recommended steps, including self-isolation.  

If you are in self-isolation
  • Do not come into work and avoid going out in public, to avoid spreading the disease further.  
  • Call your supervisor if you need to retrieve items from work, so that we can arrange for delivery.
  • Continue to work from home, if you feel well enough and are equipped.
  • Self-isolation ends after 14 days without symptoms, or sooner if instructed by a medical professional. If symptoms develop during self-isolation, notify your medical provider and follow their instructions.

Please Note: Your medical professional (including MIT Medical) will not share health information with the Laboratory, so it is important that you contact your supervisor and/or HR to report that you are self-isolating.

Medical quarantine

If you have been diagnosed with presumptive or confirmed COVID-19

  • Follow the quarantine guidance of your medical provider.
  • Do not return to work until you have received written permission from your medical provider.

Steps to prevent illness

Know How it Spreads
  • The best way to prevent illness is to avoid being exposed to this virus.
  • The virus is thought to spread mainly from person-to-person, between people who are in close contact with one another (within about 6 feet), and through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
Take Steps to Protect Yourself
  • Wear a face covering when in public to help avoid contact with your mouth and nose, and to reduce the probability of inadvertently spreading droplets. 
  • Wash your hands often with soap and water for at least 20 seconds especially after you have been in a public place, or after blowing your nose, coughing, or sneezing.
  • If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.
Avoid Close Contact
  • Avoid close contact with people who are sick.
  • Put distance between yourself and other people if COVID-19 is spreading in your community. This is especially important for people who are at higher risk of getting very sick (older adults and people who have serious chronic medical conditions).
