COVID-19 FAQ page for the SLAC community

Following guidance from San Mateo County, SLAC has limited all on-site activity to those deemed essential in supporting the DOE mission, including COVID-19-related research, site security, facility maintenance, custodial services, essential computing maintenance, and shipping & receiving. The latest shelter-in-place order, effective May 18, allows construction activities to resume. For SLAC, this means we may now be able to resume some on-site construction activities like LCLS-II.

SLAC leadership and Stanford University are actively monitoring the developing situation with respect to the spread of the disease and potential impacts to lab and university functions. This is an evolving situation - staff should check SLAC Today and this page for the latest memos and guidelines.

This page is intended to provide information relevant to the SLAC community and should not be considered comprehensive or to constitute medical, legal or other advice that can better be provided by experts in those areas.

Please note that many of the links on this site require a SLAC login.

Site Info

Can I come on site to pick up some things? (last updated 05/19)
We have developed a policy and process for employees to pick up items that they require to work from home. See more on the SLAC Today article.

Aside from this, only staff identified by the senior management team as being required on site will be allowed access.

Anyone entering through the Main Gate will need to scan their badge, and unauthorized individuals will not be allowed through. The security team at the gate will have a list of authorized individuals on hand, as well as methods for escalation if your name should be on the list but isn’t.

Alpine Gate will be closed during the curtailment period.

When might the Arrillaga Recreation Center at SLAC (ARCAS) be reopened? (last updated 05/19)
The ARCAS gym is unlikely to open before Stage 3 of our recovery plan, which is some months away. We are working with Stanford to understand what mitigations might be put in place when it does reopen, such as the spacing out of equipment.

What is the current site status at SLAC? (last updated 04/14)
In compliance with the current San Mateo County Public Health Order, SLAC has ceased all on-site functions except those deemed essential.

Together with the DOE, SLAC has identified the following functions as essential: work supporting COVID-19-related research, including bringing necessary equipment online; maintaining infrastructure to maintain the viability of the lab; janitorial services for occupied areas; computing support to maintain telework and research activities; shipping & receiving; site security; and emergency response. Staff should refer to the internal memo from March 31 for further details.

We understand that many people are juggling responsibilities such as homeschooling children and caring for family members, so we will continue to look for ways to work with staff to make this situation as manageable as possible.

Does the new shelter-in-place order mean that LCLS workers in sectors 0 to 10 will not be required to come to the site through May 3? (last updated 04/14)
That is correct. We will not be working on the LCLS-II project during the shelter-in-place period.

Will janitorial services continue?(last updated 03/24)

In support of the county shelter-in-place order, janitorial services will be reduced accordingly to support only those functions deemed essential to the laboratory. Currently, those functions include the following:

  • Security services – Building 053, 1st floor only
  • Cryo-EM and FIB-SEM support of COVID19 research – Buildings 006 and 057
  • Computing services – Building 050, 1st and 3rd floors

All regular janitorial services will be provided at the above locations only (restroom cleaning and supply stocking, conference room and break room tables and countertop cleaning). All cleaning is currently conducted utilizing a disinfectant agent. Please note – there is a national backorder on most sanitizer supplies. While we placed an order for additional hand sanitizer stations, sanitizer refills, and disinfectant wipes through Stanford, we have no expected delivery date due to current supply shortages.

Will the SLAC Occupational Health Center be open? (last updated 03/20)

OHC on-site services will relocate to Stanford OHC at 484 Oak Road, Room B15. The office in Building 28 at SLAC will close beginning Tuesday, March 17, however calls (650-926-2281) and emails (slac-ohc-staff@slac) will be answered by the same healthcare professionals as usual. When calling, please identify yourself as a SLAC employee as there may be differences in the process.

SLAC EMTs are still available on site 24/7 for medical support such as first aid.

Is Shipping & Receiving operational? (last updated 03/20)

Shipping & Receiving will be operating with a reduced staff from 6:30 a.m. to 3:30 p.m., Monday to Friday. Deliveries arriving at SLAC will be accepted and held at Shipping & Receiving until the workforce curtailment ends. Items received will be scanned and processed through PeopleSoft, with a barcode attached for property control where needed.

No deliveries will be made to buildings except those relating to essential projects and COVID-19-related research. Please contact Dan Demott or Bill Zangara with questions.

I didn’t get a chance to submit the mileage for my fleet vehicle(s) before leaving the site. (last updated 03/18)

SLAC Fleet Services will not be charging any fees for custodians who were unable to submit vehicle mileage information before leaving the lab.

How do I know if I’m required to continue working on site? (last updated 03/18)

Your leadership should have contacted you with details on which programs and operations will continue through the shelter-in-place period. If you are still unsure, speak with your manager.

Will the IT Help Desk be available? (last updated 03/18)

There will be no walk-up Help Desk support on site during this period. If you have an internet connection, the Help Desk will be able to provide support remotely. If you don’t have internet, you can call 650-926-4357 for telephone support. Due to a surge in telephone calls, it's recommended that you leave a voice message instead of waiting on hold - there is additional staff monitoring voicemail.

Will the cafeteria (SLACafe), Starbucks or gym (ARCAS) be open for those who are still on site? (last updated 03/18)

ARCAS, SLACafe and Starbucks will be closed.

Medical Guidance

The following answers to health-related questions from SLAC staff about COVID-19 have been provided by Dr. Rajan Puri and Dr. Richard Wittman from Stanford and SLAC’s Occupational Health Centers.

How long is the incubation period of the virus? (last updated 04/30)

The time from exposure to illness, or the incubation period, ranges from 2-14 days. The most common incubation period is 4-6 days, and about 80% develop symptoms within eight days, with >95% developing symptoms within 11 days.

What treatments are available? (last updated 04/30)

You may have heard about hydroxychloroquine in the news. However, Stanford Hospital does not recommend its use, as there is conflicting evidence and not enough data to determine its effectiveness. Please do not buy this medication.
The other medication that has been in the news, Remdesivir, is only available intravenously. Stanford is conducting clinical trials with hospitalized patients and recent studies have demonstrated some positive outcomes with its use earlier in the treatment course. More data to come.

How many people have the virus but don’t show symptoms? (last updated 04/30)

Original estimates were that 1-3% with COVID did not develop symptoms. Various studies, including those involving cruise ships and nursing homes, have documented rates in the 10-25% range, and Dr. Anthony Fauci of the National Institute of Allergy and Infectious Diseases has estimated it could be as many as 25-50%. These numbers can be confusing, as there is a difference between those who never develop any symptoms, those who only develop very mild symptoms, and those who develop symptoms but shed contagious virus 1-2 days before their symptoms appear. Stanford Hospital has tested thousands of healthcare professionals and found less than 0.5% with asymptomatic infection.

How effective are face shields? (last updated 04/30)

Face shields can be excellent as an adjunct for protection and can be very comfortable to wear.  They are NOT designed to protect against hazards that are respiratory in origin. So while they may block large droplets and serve as a barrier against direct impact from coughing, they alone will not meaningfully protect against airborne infection from prolonged close contact. This is a good reminder that the fit of a mask is important, and even loose fitting masks lose their protective efficacy quickly.

I live in the same household as someone who is an “essential” worker and has been going to work through SiP. Will this affect my ability to return to work since my exposure is greater? (last updated 04/30)

There are a number of personnel on site who have continued working since the shutdown, and there are many whose spouses or family members continue to work in some capacity. You will not be restricted from returning to work, and the same criteria would apply to you as others if your household member becomes sick, which is essentially staying at home while they obtain testing.

How can we confidently rely on the numbers given for cases, fatalities and rates of COVID-19 infection when the U.S. is known to be behind on testing? (last updated 04/30)

With the recent rollout of more widespread capacity to test for antibodies, we are beginning to see early return of population surveys to assess for the prevalence of COVID. That noted, the United States has wide regional differences in both testing capacity and shelter-in-place policies, which makes generalization between areas more difficult; in addition, fatality data typically lags months behind even in normal circumstances, so we will have to rely on comparing various US-based studies with those from other impacted countries to settle on general consensus numbers, if that is the goal.

Can we strengthen our immune systems against the disease? (last updated 04/30)

There are a number of studies that support the value of sleep and exercise on our immune systems, and there are various studies over the years linking low vitamin D levels with susceptibility to respiratory infection. We recommend setting aside time to go for a walk or ride a bicycle and get some sunlight (within reason), as vigorous exercise also improves sleep quality.  Avoid heavy drinking, as alcohol can impair sleep quality and lead to increased snoring and apnea, which can increase body stress levels.

What kind of testing is available, and what are the criteria to get tested? (last updated 04/30)

There are 2 main kinds of tests:

There is the ‘swab’ test, which looks for viral RNA, and it is essentially used to document whether someone has active infection. Most commonly, these samples are cultured from the back of the nose, such as during the drive-thru clinics you may have heard about. In short time, this testing may transition to front-of-nose or mouth swabbing, or even saliva collection, all of which can be performed easily, without medical training needed.

These PCR tests can stay positive for weeks after infection ends, since they detect viral fragments, so right now the test cannot easily determine if the virus detected is capable of causing infection in someone else. Stanford is working on a technique to better clarify this, which will be important to permit those who are infected, recovered, but still shedding virus to exit from quarantine at an earlier time.

The other type of test looks for antibodies to COVID and is collected via a blood draw.  This test can be a useful epidemiologic tool to assess for (generally) prior infection in a population. Antibodies to COVID can rise very early in the infection course, so the test can also detect a portion of those who are actively infected. There is much we are learning about the test, including how long the antibodies can be detectable, if antibody levels correlate with immunity, what proportion of those with mild infection develop measurable antibody levels, and how long the immunity, if present, might last. An antibody neutralization test is expected to be more widely available in the next few months, and this may add more clarity to the situation.

What about testing prior to entering the lab? At least taking employees temperatures as they enter and exit the lab. (last updated 04/30)

Completion of the daily health check tool will be required for workers, prior to coming on site. Questions relating to an employee’s temperature are embedded into the tool. Currently, we are not checking anyone’s temperature, as only a fraction of people with COVID-19 actually have a fever. Instead, they may have other symptoms, or a combination of symptoms which the tool asks about. We hope this captures many more symptomatic people early on, rather than when a fever may occur, which often occurs later in the stages of COVID-19. We are not currently testing anyone without symptoms as this is being reserved for healthcare workers in need. This may change in the future as more data becomes available, at least in terms of blood testing.

Will antibody tests be rolled out at SLAC? (last updated 04/30)

Antibody testing at Stanford is currently largely limited to research and epidemiologic studies as well as testing of first responders. Over time, this and live viral testing will become more accessible for the Stanford community and will play a vital role in early diagnosis both in those with COVID-like symptoms and in those without symptoms, as part of screening and close-contact surveys.

Will there be a differentiation in protocol for staff with a positive antibody test? (last updated 04/30)

A positive antibody test does not equate to immunity, as it is still not known to what degree, and for how long, someone who has been infected might be protected from future infection. There continues to be strong data that maintenance of social distancing, good hand hygiene, and mask use can mitigate infection risk, and this, combined with early identification of cases and contact tracing, can further reduce the risk of spread. This is an interesting topic, particularly given the discussion internationally about some countries issuing ‘immunity cards’, but there is no plan to have this testing dictate a differential response.

Can antibodies from a survivor be transferred to a sick person? (last updated 04/30)

This is called convalescent plasma transfer. There is a compassionate use policy that allows someone who has recovered from COVID-19 to donate plasma that can be given to someone else who is sick. The results of studies so far are more positive than not, and a large consortium of blood centers around the world are screening donated blood to look for those who could be good candidates for donation.

What does contact tracing look like in a scenario of a worker feeling sick and going home? (last updated 04/30)

SLAC will be piloting the newly created daily self-reporting symptom health check tool to maximize the safety of academic and work environments for everyone at on-site Stanford/SLAC locations according to guidelines from the Centers for Disease Control and Prevention (CDC) and the Occupational Safety and Health Administration (OSHA). This information can be used to proactively make decisions for return to work and contact tracing. It will also be used to keep our community safe when we expand the number of people returning to Stanford/SLAC locations. Anyone who is sick should still go or remain home, and the tool will help give clear guidance on how long you should stay home.

Can the virus infect livestock and therefore impact our meat and food supply? Do we have to be concerned about our household pets? (last updated 04/30)

Early on, in January or February, a dog in Hong Kong tested positive. More recently, a group of lions and tigers at the Bronx Zoo got the virus from a zookeeper, which is not surprising given that cats, ferrets, pigs, and non-human primates all have favorable receptor sites. We will probably continue to hear about these sorts of cases, but there aren’t many of them. So while there is a possibility that you can give it to your pet or to another living being, and that they can give it to you, there isn’t strong evidence or strong data to support the overall risk. The rule of thumb is that you should be cautious regardless.

How is Stanford planning for a surge in patients? (last updated 04/30)

Stanford is doing a lot of surge planning to prepare for additional patients, including doubling up ICU rooms and other beds. It’s not a chaotic environment at the hospital right now, like you may have heard about in other states, and the current COVID census is very low.

Can you track the virus into your home after taking a walk through the neighborhood? What is the suggested protocol for outside footwear? (last updated 04/14)

We generally recommend, even in the absence of COVID activity, that individuals do not wear outdoor shoes inside the home, and change to indoor or home footwear. The coronavirus is an enveloped virus and can easily be killed with standard cleansing measures. We would not expect that a viable virus capable of causing infection would persist on the bottom of shoes in standard circumstances, but recommend wiping down shoes after entering a healthcare environment where COVID patients are being treated, such as an ER.

Are there any plans by regional or state authorities to test all known contacts of persons confirmed with COVID-19, similar to the South Korean approach? (last updated 04/14)

This would be the ideal and desired approach. When the antibody assay is more available, we will see widespread fingerstick/blood testing to determine those who may have active infection and those who have recovered and are immune. At this stage, Stanford is one of the first places to roll out a validated test in the United States. The degree to which this testing will be performed in the upcoming months by all healthcare plans may depend on the background rate of COVID, as widespread testing has a much reduced impact if only 5-10% of people have had COVID.

Have any SLAC employees tested positive? (last updated 04/07)

We have no known cases related to SLAC at this time.

I’ve seen recommendations that we wipe down groceries when we bring them in and store them for several days before using them. Is this advisable? (last updated 04/03)
There are no recommendations from the county or CDC that we wipe down or quarantine groceries, and there is no current evidence to support the transmission of COVID-19 associated with food or food packaging, despite the time-limited presence of viral RNA on certain surfaces.  We recommend washing unpackaged foods as standard practice for fruits and vegetables, and continuing to eat a healthy and balanced diet given the more severe impact of COVID-19 in those with diabetes and elevated blood sugar.  

The decision to wipe down packaged groceries is an individual one that comes down to risk tolerance, and it may be best reserved for areas that may come into direct contact with our hands and mouths repetitively, such as the top of a milk carton, bottle, or a can.  Given that SARS-CoV2 is an enveloped virus that is easily killed during the disinfection process, washing our hands frequently and/or using alcohol-based cleaning gels continues to be a high-value and important practice, particularly after contacting high-touch areas in the grocery store and other public spaces.

Do doctors expect the COVID-19 fatality rate to drop as testing becomes more widespread? (last updated 04/03)
Yes; this is usually the case as more and more tests become available. Unfortunately, we are not there yet. We do know that health care systems that are overwhelmed see much higher fatality rates, and that’s a major driver for why we’re sheltering in place.

What are the symptoms of the virus? (last updated 03/14)

If symptoms occur, they usually occur within the first 2-7 days, but the incubation period is 2-14 days. Early COVID-19 symptoms can include a sore throat and dry cough. Fever, fatigue, wet cough, muscle aches and chills, and shortness of breath are commonly described, with fever (38°C/ 100.4 °F) and respiratory complaints the most common in those who seek medical care.  Nausea, vomiting, diarrhea and productive cough are less common symptoms, although they have been present in a lower percentage of positive cases. In more severe cases, infection can lead to pneumonia, severe acute respiratory syndrome, kidney failure and even death.

The current evidence is that most cases (~80%) of COVID-19 appear to be mild. Those with chronic underlying medical conditions appear to be at high risk for serious complications. This may include those with heart/lung issues, diabetes or those with immune-compromising conditions. Read about COVID-19 Symptoms from the CDC.

Is it possible to contract the virus more than once? (last updated 03/14)

There have been some scattered reports of patients testing negative and then weeks later testing positive.  Current data supports that individuals with COVID-19 actually begin developing protective antibodies very quickly, for some as early as 6 days into the infection. By 14 days, most have a robust and strong neutralizing antibody response. Viral shedding for many viruses can extend beyond the period of infectivity, as is the case for COVID-19, but after 2 weeks, studies have not found these viral particles capable of causing disease. However, there are recent reports of possible fecal-oral transmission.

What does it mean to be "immunocompromised"? (last updated 03/14)

When someone is immunocompromised (immune-compromised), it means that their immune system has a reduced ability to fight infections and other diseases. This may be caused by certain diseases or conditions, such as cancer and leukemia/lymphoma, diabetes and certain genetic disorders. It may also be caused by cancer treatments, such as radiation and chemotherapy, as well as by medicines used for common conditions, including steroids/prednisone and rheumatoid arthritis medication.

What are the procedures to follow for self-isolation? (last updated 03/14)

Self-isolation means avoiding situations where you could infect other people. This includes any situation where you may come in close contact with others (face-to-face contact closer than 6 feet). For example at social events, work, school, restaurants and public gatherings. See Stanford's one-page information sheet for more details on self-isolation.

What is the benefit of being tested? What is done if there is a positive or negative result (with mild symptoms, or severe ones)? (last updated 03/14)

This is an excellent question and gets to the core of the difficulty with the current public health response. Individuals with COVID-19 shed virus early in the disease course, and often in high amounts, typically peaking before day 5 of infection. Testing early would allow for identification of those who are ill at a stage when self-isolation could reduce viral exposure to the community, and as a result, slow the spread of disease. Testing negative can mean you might have another illness such as the flu or cold, which can overlap with some of the symptoms of COVID-19.
Testing positive will allow you to get treated faster and hopefully make you feel better before things get worse. Testing those who are most ill when they present to the emergency room or hospital is also beneficial, as it can help identify patients who might rapidly progress to respiratory distress and who may benefit from earlier implementation of various therapeutic options, such as medications under study for COVID-19.

Is there any expectation that the testing availability, capacity and turnaround time will improve? (last updated 03/14)

Right now this is difficult to predict, as supply shortages are reported in the national media. Stanford has developed its own FDA-compliant test and its lab can process these samples for the hospital and Stanford Express Care.  Stanford results are usually back in approximately 24 hours. However, currently,  there are some delays due to the increased demand and results may take longer. Large labs, such as Quest and LabCorp, currently have around 2-3 day turnaround times for test results. Stanford is ramping up its testing capacity, but many local hospitals are also sending their tests to Stanford, which increases the volume beyond the Stanford Health Care population.

Wouldn't it be better if everyone with potential for having COVID-19 was isolated and tested, even if for many of them the symptoms are mild? (last updated 03/14)
It is indeed true that testing early and often would be the most effective manner to accurately identify who best to isolate to reduce disease transmission. Unfortunately, due to lack of testing availability to date, clinicians have been limiting testing to those who are most sick.
In the absence of wide-scale isolation measures, such as seen in China and Italy, this essentially means that COVID-19 will likely continue to spread, absent another factor that may slow or halt disease transmission, such as a medication or vaccine. Having individuals stay at home when feeling the first sign of illness, and practicing social distancing and good hand hygiene, however, may also have significant positive impacts. Limiting events where one sick person may infect tens to hundreds (such as at a large conference), can modify the disease curve.



Will SLAC compensate employees working at home for their internet service expenses? (last updated 04/15)

In accordance with the labor code, we will be providing a stipend to people working mostly from home based on our records of submitted temporary telecommuting agreements. This stipend will only be provided for the duration of the shelter-in-place order. If you have not done so already, please work with your manager to get that agreement submitted. See the internal memo for details.

How are we addressing concerns about Zoom security? Are we thinking about switching to other platforms or applications? (last updated 04/14)

Zoom remains the recommended and supported meeting platform for Stanford and SLAC. We have published best practices for how to secure your Zoom meetings, including a SLAC Today article with links to the Stanford UIT guidance, which is consistent with ours. Stanford’s chief information security officer and chief privacy officer, Michael Duff, has also posted tips for enhancing Zoom security.

We strongly recommend that you disable the feature that allows people to join before the host. This ensures there are no opportunities for people to hijack or “Zoom-bomb” the meeting. For meetings that are internal to SLAC and Stanford only, you can also enable the feature that requires people to sign in with their Stanford user ID.

Stanford still approves Zoom for high-risk data. Our cybersecurity team will be investigating concerns that have come up regarding Zoom’s business practices, their authentication mechanisms and other vulnerabilities.

Please be sure to keep the software updated, as Zoom has been pushing through a number of security updates to address vulnerabilities.

Are the Directorate Appointment and Promotion Committee (DAPC) and Laboratory Appointment and Promotion Committee (LAPC) active during the shelter-in-place period? (last updated 04/07)

Yes, this work is continuing remotely.

How do I start telecommuting? (last updated 04/03)

Coordinate your telecommuting plans with your manager and complete the temporary telecommuting form, then submit to your Business Manager. Below are tips and guidelines on getting set up.

What is the purpose of the temporary telecommuting agreement form? Can we streamline it? (last updated 04/03)

The form helps us comply with Stanford requirements and will be required for anyone who qualifies to receive the internet stipend (see Cardinal at Work FAQs for more - but note that the Stanford temporary telecommuting agreement form is different to SLAC’s). It also helps set expectations between managers and employees on continuing to work productively during the shelter-in-place period, and document who has SLAC property with them during this time.

This temporary form, which is different to our standard telecommuting form, was put together quickly in response to a rapidly changing situation. HR is working to streamline the process, so that renewals or changes to agreement conditions can be done easily.

If I already have a regular telecommuting agreement, do I need to complete the temporary one? (last updated 04/03)

Yes. The parameters in the original full-scope agreement are different from those in the temporary one. If you are working from home and you haven’t completed the temporary form, please work with your manager to fill it out and submit it to your organization’s business manager.

What if the space in my home does not meet all the criteria on the temporary telecommuting agreement (such as fire extinguisher or bookcases bolted to the wall)? (last updated 04/03)

The points listed in the tables following the letter are tips and recommendations for a safe and optimal workspace at home; these are not required for the purposes of the temporary shelter-in-place order.   

What do I do with the completed temporary telecommuting form? (last updated 04/03)

Once managers have signed the agreement, please send to your organization’s Business Manager, who will channel them through to HR.

How can I make sure my home workstation is ergonomic? (last updated 04/01)
The shelter-in-place order does not allow employees to come to SLAC to retrieve existing equipment, but you can get a virtual ergonomic evaluation of your home setup and work with the ergonomist and your supervisor to obtain equipment that you need. See internal memo for more guidance.

What if I get sick while working from home? (last updated 03/20)

If you become ill, self-isolate and continue to monitor your symptoms. If your illnesses worsens, contact your physician, especially if you have a fever, cough and shortness of breath. If you have been tested for COVID-19, please contact OHC and log into the Stanford employee health portal using your SUNet ID and password to complete the COVID Case Evaluation Form. OHC staff will follow up on positive cases. If you test positive, please consult with OHC before returning to work.

Stanford provides guidance on preventing illness and maintaining both physical and mental well-being.

According to the CDC, people at higher risk for serious illness from COVID-19 include older adults and those with severe chronic conditions like heart, lung or kidney disease. Learn more on their website. We encourage employees to follow the CDC’s preventive hygiene guidance. When these measures are practiced with diligence, the spread of disease is greatly minimized.

Will the IT Help Desk be available during the shelter-in-place order? (last updated 03/18)

There will be no walk-up Help Desk support on site during this period. If you have an internet connection, the Help Desk will be able to provide support remotely. If you don’t have internet, you can call 650-926-4357 for telephone support. Due to a surge in telephone calls, it's recommended that you leave a voice message instead of waiting on hold - there is additional staff monitoring voicemail.

Will any Computing services be affected by the shelter-in-place order? (last updated 03/18)

The Computing team plans to keep all services available during this time.

What if I’m unable to work from home and have not been asked to continue working on site? (last updated 03/18)

In the event that you are not working on essential on-site activities and cannot work from home, we have enabled the "Site Curtailment - WS" leave code in all employees’ timesheets. Please discuss with your supervisor in advance.

How do I get on the SLAC computer network from home? (last updated 03/16)

Many remote tasks, such as email and productivity applications, do not require access to the SLAC network. For the tasks when internal network access is required, SLAC computing has a detailed guide for connecting to the lab's Virtual Private Network (VPN). There are further instructions on working remotely in the remote worker toolkit as well.

Please be aware that in a case where a large number of employees are using the SLAC VPN simultaneously, there's the possibility that bandwidth could be constrained. For this reason, please run the VPN only when required, not by default. 

In general, disconnect from the SLAC VPN when you no longer need it and re-establish the connection when it's needed. If you have applications or services that don’t work when connected via home or outside networks, then use VPN. Otherwise, leave the service available for others. Additionally, when using SLAC VPN, limit or reduce use of applications that have steady continuous network use – e.g. when using tools like Zoom where you don’t need to access SLAC applications or services during the meeting, disconnect from VPN.

How can I get my SLAC voicemail from home? (last updated 03/16)

Staff can access SLAC voicemail from offsite by dialing in to 650-926-4242.

In addition, in response to the curtailment of onsite work, SLAC computing has enabled a feature that will forward SLAC telephone voicemails to the associated SLAC email. When someone leaves a voicemail it will trigger an email notification to your email inbox with an attached .wav audio file.

If you have any issues or questions regarding this new feature or other aspects of SLAC telephone service such as call forwarding, please contact

How can I stay connected with colleagues while I'm working remotely? (last updated 03/13)

With many SLAC staff members working from home, it's important for communication and collaboration to continue. Fortunately, Stanford and SLAC provide many tools to you free of charge to make that possible. 

SLAC Computing's collaboration support page contains details on how to connect to several of these, as does Stanford UIT's collaboration tools page.

Recommended tools include:

Instant Messaging: Stanford/SLAC Slack - chat and collaborate in real-time with SLAC colleagues (SLAC on Slack (internal) and Stanford UIT's Quick Guide to Slack Best Practices)

Audio/Telephone/Videoconferencing: Zoom - professional-quality teleconferencing and virtual meetings (Best Practices for Effective Video Conferencing

Google Collaboration: G Suite (Google Drive, Docs, Sheets, etc.) - enterprise access to cloud-based collaboration on Google's most popular applications (Stanford G Suite Services - use SUNet login)

Microsoft Collaboration: Office 365 (Microsoft Word, Excel, SharePoint, Teams, etc.) - enterprise access to cloud-based collaboration on Microsoft's most popular applications (SLAC Office 365 - use SLAC login)

Are there any precautions I should take if I use my SLAC laptop at home? (last updated 03/11)

Employees who are approved to telecommute must have the appropriate equipment and access to systems, and meet the cyber security requirements for using work technology in their homes. When employees connect to the SLAC network via VPN, the system is inspected to ensure it meets the SLAC security requirements before being granted access. All systems are required to be fully patched and have antivirus installed and up to date.  For reference, please see SLAC’s minimum IT equipment security requirements (password required).

See Computing’s Remote Worker Toolkit for more information. 

Employment & Benefits

Some of these questions followed Provost Drell's message to the Stanford community about the university's actions in response to financial challenges. Though SLAC's operating contract is managed by the university, our funding comes from the DOE, so some of the actions announced may vary in implementation at the lab. See the internal memo for more.

Is there a cap on the use of the curtailment code? (last updated 05/11)

The DOE has eliminated the original 320-hour cap, and the curtailment code is available as needed until Sept. 30, 2020, or until an individual who wasn’t able to telecommute has their schedule fully restored with on-site work. In the meantime, the DOE’s expectation is that staff continue to work with their managers to find ways to stay productive while at home.

Will charging to the curtailment code affect job evaluation or retention? (last updated 05/11)


Will the vacation accrual cap be increased for those nearing the maximum hours accrued?  (last updated 04/28)

There is no plan to extend the vacation accrual cap. You are encouraged to plan for (with your manager’s approval) and use vacation time to refresh, rejuvenate, and prevent maxing the accrual threshold.

Will employees be able to make changes to their Dependent Day Care FSA benefit election or will the carryover limit be increased? (last updated 04/28)

A change in dependent care cost or provider allows you to reduce your election to your dependent care flexible spending account. Please see the Cardinal at Work website for more information on this and other benefits-related impacts. The Stanford HR Services Team can answer any other questions regarding staff benefits.

Will there be an extension to our FY20 STAP funds? (last updated 04/28)

Unused FY20 STAP funds will not roll over into FY21. There are many courses still available online for continuing studies, professional development, technology training and more - we encourage you to use your STAP funds for these opportunities.

Many technicians who work for LCLS-II have contracts ending in the July-August timeframe. Are we considering any type of contract extensions due to circumstances, ­such as delays, a slow restart or any other constraints? (last updated 04/15)

We are working with Procurement and HR to investigate what options may be possible for extending contracts, and reviewing on a case-by-case basis, depending on the work involved.

Can fixed-term lab employees whose agreements are about to end be extended on a flexible basis? (last updated 04/15)

We are exploring options on how to handle these contracts on a case-by-case basis.

Will promotions approved before April 2 be affected by the pause on hiring or salaries? (last updated 04/15)

Promotions that have already been approved will proceed, but new promotions that are just being put forward or considered will be paused while we assess further information and timing.

Will staff be asked to take pay cuts? (last updated 04/15)

There are no plans to ask staff to take pay reductions.

Are relocation and sign-on bonuses still available as part of the recruiting process? (last updated 04/14)


What charge code should be used to attend things like lab-wide town halls? (last updated 04/07)

You should charge your "normal" charge code. That is, if you generally charge your time to a project or indirect account, you should charge these meetings to that code. Otherwise, you should charge to the indirect charge code of your organization.

Will I continue to be compensated during the curtailment of on-site operations? (last updated 04/03)

All staff will continue to be compensated during the curtailment period.
Everyone should be communicating with their manager to identify things they can do to be productive. Charge your usual codes for productive hours, and use the “Site curtailment - WS” code where necessary - see internal memo for further guidance. The purpose of the site curtailment code is to ensure you continue to be compensated during this period. Neither does it have an expiration date; it’s designed to help us respond appropriately to evolving circumstances.
In line with DOE guidance, SLAC is paying for work covered by the curtailment code through our normal “leave rate,” which covers the cost of sick time, vacations, jury duty, PTO, etc. That rate is normally roughly 18% of our labor cost. When the curtailment ends, we will reassess and adjust our leave rate so the cost is distributed out over our normal budgets.

Are casual employees still only paid for hours actually worked, as usual, or are they able to use the curtailment code? (last updated 04/03)

Casual employees will continue to be paid only for actual hours worked, as usual.

What if I’m unable to work from home and have not been asked to continue working on site? (last updated 03/18)

In the event that you are not working on essential on-site activities and cannot work from home, we have enabled the "Site Curtailment - WS" leave code in all employees’ timesheets. Please discuss with your supervisor in advance.

Recovery Planning


Is returning to work going to be based on need or how much we’ve charged to curtailment? (last updated 05/11)

Decisions on work prioritization won’t be based on curtailment code use. Stage 0 activities need to meet very specific definitions of essential work. Stage 1 work will be based on the Senior Management Team’s guidance on priorities.

How much notice will staff be given to return to work on site? (last updated 05/11)

During Stage 0, employees have been given between a few days’ notice to as much as two weeks’. While planning for Stage 1, we’re trying to get that notice period closer to two weeks wherever possible.

What is the process for approval of on-site work? (last updated 05/11)

Line management develops work plans on a week-by-week basis and completes the appropriate Job Safety Analysis (JSA). Line managers and ES&H coordinators first determine the appropriate level of work based on JSA descriptions, and identify the effective start date of the work after JSA approval. This will be relayed to the employee performing the work, giving them time to review and discuss the plan before coming on site.

Employees can only work on site to perform those activities that have been identified and approved.

Will special training be required for staff returning to work on site? (last updated 05/11)

During the week of May 11, ES&H Course 100 (“Covid-19 Training for Onsite SLAC Employees”) will be rolled out to all staff working on site. This module will be a required training for any staff returning to work on site in future.

Do SLAC staff need to complete Stanford’s “COVID-19 Hygiene Best Practices” training? (last updated 05/11)

All SLAC staff returning to work on site will need to complete ES&H Course 100 (“Covid-19 Training for Onsite SLAC Employees”), which will launch during the week of May 11.

If you only work at SLAC, you do not need to complete the Stanford training.

If you work at both SLAC and on campus, you must take both training courses.

Where on the priority list is lab access for PhD students and postdocs who need to continue making progress toward graduation? (last updated 04/29)

While in Stage 0 (essential operations), no lab work is being performed except in support of COVID-19-related lab work. Stage 1 will primarily focus on bringing elements of some projects back up, but won’t necessarily include research activities. These will set the path for us to move into Stage 2 (e.g., restart of LCLS). Stage 2 is when we will be able to start resuming many of the research activities involving PhD and postdoc support. SLAC and Stanford’s research recovery plan are very similar in this regard. 

How will buildings be prepared for reoccupation? (last updated 04/28)

F&O will coordinate with building and area managers to conduct walk-throughs, inspections, and assessments of facilities before re-occupancy. This process will involve a comprehensive review of building occupancy, mission use, and cleaning needs, as well as preparation of common spaces for safe use. Facilities and buildings supporting Stage 1 activities will be prioritized, while other buildings and communal spaces (SLACafe, Starbucks, ARCAS, and Panofsky) will likely be assessed later in Stage 1 or into Stage 2. Note that as the virus cannot live for long on surfaces, buildings that have been unoccupied for several weeks will be safe for occupancy.

What is SLAC’s plan to help parents transition to work where they have school-aged kids but no daycare options? (last updated 04/28)

We know that this is a big concern for many of our staff; we are working on a plan that will take these needs into account - stay tuned.

How will SLAC manage impacts to operations and project costs? (last updated 04/28)

We are closely monitoring costs and deliberating on how we will need to adjust our rates as a result of cost increases. This involves working closely with our sponsors to balance cost with the delivery of project milestones. As our primary funding source, the DOE has been very supportive of the lab through this time, and has received considerable incremental funding to help address the current situation.

When will the run schedules for facilities be made available? (last updated 04/28)
We’re currently working on the re-commissioning plan for LCLS. Initial work has started on the first task (certifying the Personnel Protection Systems), which will likely take a month or so. This will be followed by commissioning of the linac and the new undulators. At that point, we can start instrument commissioning and experiments. While we’re unable to confirm a timeline yet, we have sent out a call for proposals to the LCLS User community for initial experiments which will focus on COVID-19.
SSRL is currently operating a few beam lines for COVID-19-related research via remote access, with SPEAR3 at full current, and with minimal staffing. Run schedules for non-COVID-19 research will remain uncertain until the light source has started recovery for full operations. This will happen after the San Mateo County shelter-in-place order is lifted or modified in such a way that SLAC can start work on high-priority activities. The situation is too uncertain at the moment to provide any kind of timeline.

When will SLAC return to normal operations? (last updated 04/01)

On March 31, San Mateo County Health extended the shelter-in-place order until at least May 3. A determining factor in how long the shelter-in-place will last is when the number of new COVID-19 cases per day stabilizes and then starts to significantly decrease. However, the lifting of the order doesn’t mean operations will immediately return to normal.

To prepare, the lab has formed a Recovery Planning Task Force, led by Jeff Sims. Recovery will be a complicated process, executed carefully and in stages. Representatives from mission and mission support functions are involved in this effort, and leadership will inform their organizations when their recovery activities can begin. See SLAC Today article for more.

Will the schedule date for LCLS-II first light be moved out? (last updated 04/01)
The lab is discussing with DOE how the shelter-in-place curtailment of on-site activities may affect the schedule, including considerations of moving project milestones. The impact will ultimately depend on how long the curtailment lasts.

On-site Safety


What protocols are in place for the use of masks on site? (last updated 05/11)

SLAC purchased cloth face coverings and began distributing them to on-site personnel on April 17. San Mateo county has also enacted a requirement for the use of face coverings when working or accessing essential services, effective April 22.

Anyone who will be interacting with others on site will need to wear a face covering. Even if you are working in isolation, you should carry a face covering with you at all times in case the need arises. Please refer to the COVID-19 Protocol Matrix (pdf) for further guidance.

Some activities will require Personal Protective Equipment (PPE) like N95 respirators and disposable gloves. Use of N95s will require medical clearance and fit-tests; being clean-shaven is another requirement for use. If you do not have medical clearance, we can look at other protective options, per SLAC’s usual protocol.

Homemade face coverings are acceptable as long as they meet SLAC and CDC requirements (pdf), such as having two or more layers of fabric.

It is each individual’s responsibility to care for and wash cloth face coverings before first use and after every shift.

Please also note that SLAC and Stanford are in two different counties (San Mateo and Santa Clara, respectively), so county requirements may differ across the two.

Will Health Check compliance be checked at the Main Gate? (last updated 05/11)

At the moment, there is no feasible way to check all people coming in through the Main Gate. The participation of all personnel in the daily health checks is key to the tool’s effectiveness.

We are currently working with Stanford IT, OHC and Security to investigate ways to tie in site access with completion of the health check, whether through a barcode on your phone or through the badging system.

Will external contractors be required to use the Health Check tool? (last updated 05/11)

We’re in discussions with Procurement, Legal, and contracting companies on the best way to implement employee screening for those employees - whether they use the Stanford Health Check tool or an equivalent program run by the contracting company.

What is the safety protocol for vehicle use during field work at SLAC? Can personal vehicles be used? (last updated 05/11)

Personal vehicles can be used for field work at SLAC. Safety protocols for shared SLAC vehicles are covered in the Shared Vehicles: Guidelines for Sanitizing (pdf) and Carpooling On-site Protocol (pdf) documents on the ES&H COVID-19 Resources website.

How are we planning to control outside vendors and deliveries - will incoming drivers or visitors be screened? (last updated 05/11)

All outside vendors and contractors are required to comply with SLAC’s COVID-19 health and safety protocols, including requirements for face coverings, daily health screenings and clean-as-you-go.

Can I wear my own N95 mask instead of a cloth face covering? (last updated 04/29)

N95s with no exhalation valve can be worn in place of a cloth face covering.

What about face shields? (last updated 04/29)

Without empirical data on the effectiveness of face shields, we will not change our policy at this time, though perhaps such studies will be added to the literature in the near future.

Are the wildfire N95 masks with the vent safe for others? I read an article that said they are safe for the wearer but may not be safe for others. (last updated 04/29)

N95s with no exhalation valve can be worn in place of a cloth face covering. For Level 4 activities (per SLAC’s COVID-19 Protocol Matrix), N95s with exhalation valves are acceptable because everyone in the area would be required to wear an N95 or greater.

For Level 4 work, will there be exceptions if N95 masks are not available? (last updated 04/29)

At this time, only an N95 or better (i.e. half-face or full-face respirator) are acceptable for Level 4 work.

San Mateo County requires a face covering “in public.” Does that apply to anyone working at SLAC, even in isolation? (last updated 04/29)

Face coverings are not required for working alone. They are required at SLAC when you do or may interact with other people.

Where are the cloth face covers provided by SLAC coming from? (last updated 04/29)

SLAC has purchased and will continue to try to purchase supplies from local businesses.

What are some other ways in which risk can be reduced while working on site? (last updated 04/29)

In addition to following SLAC's COVID-19 Protocol Matrix regarding face coverings, PPE, clean-as-you-go and social distancing, consider keeping internal doors open if they don’t need to be closed. Rather than grabbing a door handle, use accessible doors where available, which can be opened by pressing a button with your elbow or shoulder.

And as the CDC has repeatedly advised, washing your hands with soap and water is the most effective way to combat the spread of the virus.

What cleaning materials will be provided to support clean-as-you-go protocols on site? (last updated 04/28)

Currently, on-site personnel supporting essential activities are supplied by a mixture of donations and early procurement of wipes and sanitizer that are being distributed by Security since the start of the shelter-in-place orders. These are supplemented by supplies already on hand within directorates/departments.

As part of Stage 1 of recovery planning, we aim to procure wipes and sanitizer in bulk and stock them in Building 81. However, supplies are scarce nationwide and a consistent supply chain has not yet been established. F&O will coordinate with directorates and divisions to anticipate usage rates of materials and to replenish stock as needed. As always, departments will also have the ability to procure smaller volumes of administrative supplies using GSS and other purchase card sources.

How can we prevent a resurgence of infection once we come back to work? (last updated 04/14)

For essential workers that are returning to SLAC to perform essential work, for example at SSRL or the cryo-EM facilities, there are plans in place for how they can keep social distance and be safe.
As part of the lab’s recovery planning, Jeff Sims and his team have been working to understand what kinds of protocols and industrial hygiene processes we need to put in place, task by task, to make sure everyone is safe.
The most important thing to know is that we won’t do work if we don’t feel we can do it safely. We’re going to take our time, be intentional and be very thoughtful as we put together these processes with input from those who will do the work.

What do I do if I'm ill and have been asked to work on site? (last updated 03/20)

If you are ill, don't come to work - stay home and self-isolate. Notify your supervisor and contact OHC if you have COVID-19-like symptoms (fever, cough and shortness of breath). If you have been tested for COVID-19, please contact OHC and log into the Stanford employee health portal using your SUNet ID and password to complete the COVID Case Evaluation Form. OHC staff will follow up on positive cases. If you test positive, please consult with OHC before returning to SLAC.

For all other illnesses, the guidance is to stay home for 72 hours post recovery. Contact OHC if you have questions.

How SLAC is Helping


What research is SLAC involved with to help with the pandemic? (last updated 05/11)

SSRL was turned back on during the week of March 23 with the intention of supporting COVID-19-related research. Several of the beam lines are optimized for remote use, allowing research to be conducted with very few people needed on site. In the same way that research at SSRL has contributed toward a better understanding of past epidemics such as the SARS coronavirus and Zika virus, we now hope to understand the atomic structure of the COVID-19 virus.

The Stanford-SLAC Cryo-EM Facility is also being used to aid in COVID-19-related research. Cryo-EM allows us to study single particles without the use of crystals, making it easier to see the structures of cells. One of the unique capabilities at our facility is the ability to create 3D images of cell structures.

Equipment has been installed in the Arrillaga Science Center (Building 57) to supplement research already taking place in Building 6. Of particular interest to our researchers is how the virus enters a cell and interacts with cellular components.

Other activities we are involved in include working with the Joint Initiative for Metrology in Biology (JIMB) to develop global testing standards to ensure reliable testing for the coronavirus; studying ways to sterilize N95 masks with heat; designing noise-immune cables for remote control ventilators to reduce PPE usage; and prototyping a low cost, crisis-use ventilator using commercial off-the-shelf (COTS) and ICU-approved parts.

How is SLAC working with the DOE and other national labs? (last updated 05/11)

SLAC is part of the Department of Energy’s COVID-19 Working Group, which brings the 17 national labs together as a single virtual lab. The working group, also called the National Virtual Biotechnology Laboratory (NVBL) consortium, is led by Office of Science Director Chris Fall and leverages the broad range of advanced scientific tools, deep technical knowledge, and unique expertise of all 17 national labs in a coordinated and rapid response to COVID-19.
This system-wide effort is developing ideas and approaches in a number of areas, including bioimaging, therapeutics, computing, sterilization and decontamination, viral fate and transport, next generation testing, large scale environmental testing, materials and advanced manufacturing, and supply chains, with $100m in funding from the Coronavirus Aid, Relief, and Economic Security (CARES) Act. SLAC is part of six multi-lab proposal teams that have made submissions for the NVBL R&D initiative.
Our people are also teaming up with the Bay Area labs (LBNL, Livermore and Sandia) to plan a local, virtual lab to provide a framework for the national collaboration.

Could LCLS help in COVID-19 research? (last updated 04/07)

Yes – X-ray Free Electron Lasers such as the Linac Coherent Light Source (LCLS) produce extremely bright pulses of X-rays that allow us to study the coronavirus under natural conditions, such as at room temperature. This can more accurately reveal how the virus is structured, how it attacks a host, and how it interacts with potential drugs under conditions that are close to those in the human body.

An important benefit for coronavirus research is the ability of LCLS to obtain high resolution structures of proteins from very small crystals that would otherwise be unsuitable for such measurements. This is important in the development of antivirals because the envelope protein that enables infection by the coronavirus is very difficult to crystallize.

Rapid access to LCLS beam time will be prioritized for coronavirus research, with an emphasis on crystals of the proteins bound with known drug candidates. The ability to screen large numbers of such complexes will accelerate effective therapy development.

What can SLAC and our employees do to donate supplies or help the community? (last updated 04/01)

SLAC is involved in efforts by both Stanford and the Department of Energy to help with medical equipment shortages. Stanford’s Haas center is also working on creating a website with information on how to give back locally, which we will share with staff when ready.

The DOE’s Office of Science has formed a working group with representatives from all 17 national labs to tackle a number of challenges, such as producing medical masks using 3D printing and increasing the capacity for COVID-19 testing. We have also, along with the other labs, provided the DOE with information on what excess PPE we have that could be provided to support healthcare.

SLAC has also formed a working group at the lab to coordinate with the DOE and to connect Stanford with this process.

The Communications Team has compiled a list of ways in which individuals can help the community, and created a Slack channel to connect people interested in contributing. See the SLAC Today article for more.

What if I have PPE on site at SLAC that I want to donate? (last updated 04/01)

Please contact SLAC’s emergency manager, Lance Lougee, with the location of your PPE and he will arrange to have it added to our inventory.


What about personal travel? (last updated 03/17)

While personal travel is up to your discretion, the lab advises against it. See the CDC's Coronavirus Disease 2019 Information for Travel for more guidance. Also refer to the following question about returning to the lab following travel.

If I do need to travel, when will I be allowed back to SLAC? (last updated 03/17)

If you (or a spouse/housemate) are returning from travel, you will need to receive clearance by the SLAC Occupational Health Center (OHC) (650-926-2281) prior to coming on site. The OHC clinicians will conduct phone interviews as part of the risk assessment process, with clearance typically granted after 14 days. This includes personal travel.

Can I still travel for work? (last updated 03/16)


ALL official DOE travel - domestic as well as foreign - is now mission critical only (with an extremely high bar on international travel per the Secretary). All approval notifications sent on Thursday, March 12, 2020 by Travel@SLAC are null and void. Please note: If travel occurs, it is at the risk of the traveler and will not be reimbursable.

Please do not submit any new travel requests unless it is to expense costs associated with COVID-19. All auto-approved Concur domestic travel is null and void until further guidance is provided by leadership. If you have canceled a trip related to COVID-19 and there are no costs associated with the travel, please recall your travel request. If there are costs associated with COVID-19 please submit your expense report and include COVID-19 in the title of the expense report.

Please see the COVID-19 Travel FAQs and Reimbursement Guidance on the Travel Website to guide you through the process or reach out to Travel@SLAC for assistance. SLAC's travel managers thank you for your patience through this fluid situation!

Events & Tours


What are the plans for summer internship programs? (last updated 04/28)
We are exploring what can be done for each of these programs, including discussions with DOE on the programs they sponsor and with mentors within the lab to see if it’s practical for students to work on projects remotely. In doing this, we need to consider not just the work itself, but whether it can offer the intern a safe, meaningful and productive learning opportunity if done remotely. At this time, we anticipate that internships will proceed only if they can be managed virtually.
For example, the LCLS summer internship program will be remote-only for interns and mentors who have a suitable research project that can be performed remotely - e.g. design, data analysis, or programming. For specifics on how the program will differ this year, contact Alan Fry.

What's happening with SLAC events? (last updated 04/02)

Face-to-face meetings and events have been postponed or cancelled until further notice except in cases where they can be conducted virtually.

How do I get reimbursed for cancelled events? (last updated 04/02)

SLAC staff affected by cancellations of external meetings and events, such as the APS March Meeting, should pursue refunds for registration and travel costs where available. See the COVID-19 Travel FAQs and Reimbursement Guidance for details.

When will SLAC resume tours? (last updated 04/02)

All SLAC tours are cancelled at this time until further notice. We will be taking guidance from public health officials when planning the resumption of tours and other events. Please check our website for updates on public tours and educational tours.

User Info


What procedures will be in effect for external/international Users at our facilities? (last updated 04/28)
The goal is to ensure the health and safety of everyone on site, so visitors to the lab will also be subject to our new procedures. Having said that, we likely won’t host Users at our facilities anytime soon. With most universities and research institutions prohibiting travel for their staff and students, we will engage with our external User community to look at other ways to collaborate, including options for remote access to our facilities.
When will the run schedules for facilities be made available? (last updated 04/28)
We’re currently working on the re-commissioning plan for LCLS. Initial work has started on the first task (certifying the Personnel Protection Systems), which will likely take a month or so. This will be followed by commissioning of the linac and the new undulators. At that point, we can start instrument commissioning and experiments. While we’re unable to confirm a timeline yet, we have sent out a call for proposals to the LCLS User community for initial experiments which will focus on COVID-19.
SSRL is currently operating a few beam lines for COVID-19-related research via remote access, with SPEAR3 at full current, and with minimal staffing. Run schedules for non-COVID-19 research will remain uncertain until the light source has started recovery for full operations. This will happen after the San Mateo County shelter-in-place order is lifted or modified in such a way that SLAC can start work on high-priority activities. The situation is too uncertain at the moment to provide any kind of timeline.

How will visitors and Users be affected by the temporary curtailment of on-site activity at SLAC? (last updated 03/14)

Visitors and Users will not be allowed on site during this period. The User Offices will update the community with updates as they develop.
