However, there is some overlap between common seasonal allergy symptoms and some of the symptoms that have been reported by people with COVID-19 (e.g., headache, sneezing, cough). This 0.3 µm particle approximates the most penetrating particle size (MPPS) through the filter. ... employee questions related to COVID-19 and how to determine pay and leave status for employees who have been screened out. What is a HEPA filter and why would I want to use a portable HEPA air cleaner? Most of the respiratory droplets and particles exhaled during talking, singing, breathing, and coughing are less than 5 µm in size. The notion that U.S. employers would engage in broad-scale temperature screening of employees would have once been essentially unthinkable. However, the virus generally does not travel through the air by itself. CDC has also released guidance about return to work criteria for HCP with COVID-19 and strategies for mitigating HCP staffing shortages . Thus, conservative estimates of k are often used (as described above). It can take several minutes for particles 10 µm in size to settle, while particles 5 µm and smaller may not settle for hours or even days. Cloth face coverings should be washed and dried after each use. CDC does not yet know if people who recover from COVID-19 can get infected again. These Guidelines and Procedures MUST be implemented at all times on all construction sites. CDC suggests checking employees’ temperatures daily in Silicon Valley and Seattle San Jose, the seat of Santa Clara County, which has seen 45 … We appreciate your patience. Examples of “less-clean” spaces might include spaces that contain known/suspect infectious persons or spaces where a known activity has increased likelihood of generating infectious airborne particles. It has a series of questions and recommends what level of medical care, if any, the user should seek. Make a visual inspection of the employee for signs of illness, which could include flushed cheeks or fatigue. While large droplets (100 micrometers [µm] and larger) will settle to surrounding surfaces within seconds, smaller particles can stay suspended in the air for much longer. A MERV 14 filter is at least 75% and 90% efficient, respectively, at capturing those same particles. Critical infrastructure employees should follow, Employees not considered exposed should self-monitor for. They are not considered PPE. What should I do if I find out several days later, after an employee worked, that they were diagnosed with COVID-19? These professionals can assist by doing necessary calculations, making fixture selections, properly installing the system, and testing for proper operation specific to the setting. Research shows that the particle size of SARS-CoV-2, the virus that causes COVID-19, is around 0.1 micrometer (µm). Employee Screening for COVID-19 To help protect the public against the spread of COVID-19, it is strongly recommended that all employees perform a daily symptom assessment each day before work. Consider scheduling handwashing breaks so employees can wash their hands with soap and water for at least 20 seconds. If cloth face coverings are provided by the employer, a clean face covering should be issued to replace the soiled one. The technology uses ultraviolet (UV) energy to inactivate (kill) microorganisms, including viruses, when designed and installed correctly. * Definitions represent CDC-designated guidance and symptoms of COVID-19 at the time of drafting. It is important to take into account whether an individual’s symptoms are compatible with the usual symptoms and timing for allergy in that person. Follow the manufacturer’s instructions for all cleaning and disinfection products for concentration, application method, contact time, and required PPE. Social distancing means avoiding large gatherings and maintaining distance (at least 6 feet) from others when possible. As a rule of thumb, rooms with higher airflow rates (6 ACH and higher) and good placement of supply and exhaust grilles (hospital airborne infection isolation rooms) are considered to have “good” mixing and thus a mixing factor of k = 3 is often used for these spaces. The CDC released specific guidelines this week for what a return to office buildings should look like, including temperature checks, mandatory masks, … Implementing telework and other social distancing practices, Actively encouraging employees to stay home when sick, Providing supplies and appropriate personal protective equipment (PPE) for cleaning and disinfecting workspaces, Requiring all employees to wear cloth face coverings. If the room in which the air cleaner will be used is taller than 8 feet, choose an air cleaner with a proportionally higher CADR than that based simply on square footage. See Implementing Safety Practices for Critical Infrastructure Employees Who May Have Had Exposure to a Person with Suspected or Confirmed COVID-19 for more information. This is why administrative and engineering controls are emphasized in guidance to slow the spread of COVID-19. Was the technology evaluated for potential adverse health effects or occupational exposures? To ensure continuity of operations of essential functions, CDC advises that critical infrastructure employees may be permitted to continue work following potential exposure to COVID-19, provided they remain asymptomatic and additional safety practices are implemented to protect them and the community. Open outside doors and windows to increase air circulation in the area. Does germicidal ultraviolet (GUV) disinfection kill the virus that causes COVID-19? Either have employees fill it out from home before they leave for work or place a large QR-code at the entrance that employees and visitors scan to start the screening. Engage with a ventilation engineer, and if the engineer recommends installing such a system, obtain a guarantee as to expected disinfection performance. CDC Guidance: Employee Risk Assessment for COVID-19 Exposure Updated: 5/1/20 c Examples of brief interactions with COVID -19positive patientinclude: having a brief conversation at a triage desk, briefly entering a patient room but not having direct contact with the patient or the patient’s secretions/excretions, and entering the patient room immediately after the patient was discharged. One way to do this for room air cleaners is to select a HEPA fan system with a Clean Air Delivery Rate (CADR) [See EPA’s Guide To Air Cleaners In The Homepdf iconexternal icon] that meets or exceeds the square footage of the room in which it will be used. The legal advice we received from an employer’s perspective is that the assessment questions follow the exact questions offered by the public health officials. Consider focusing the screening questions on “new” or “unexpected” symptoms (e.g., a chronic cough would not be a positive screen). When should an employee suspected or confirmed to have COVID-19 return to work? Temperature Screening. Although there are many different symptoms that may be associated with COVID-19, you may not want to treat every employee with a single non-specific symptom (e.g., a headache) as a suspect case of COVID-19 and send them home until they meet criteria for discontinuation of isolation. How do I handle personal protective equipment (PPE) waste? EMPLOYEE COVID-19 SCREENING QUESTIONNAIRE The safety of our employees is our overriding priority. Make sure that employees know which cleaning chemicals must be diluted and how to correctly dilute the cleaners they are using. Employees who are well but who have a sick family member at home with COVID-19, or who have been exposed to a co-worker with confirmed COVID-19, should notify their supervisor and refer to the CDC guidance for how to conduct a risk assessment of their potential exposure. These systems are designed to serve one of two purposes: Far-UV is one of many emerging technologies that have become popular during the COVID-19 pandemic. No. Employers in these sectors should closely review the CDC’s new guidance and contact legal counsel with further legal questions. Prior to a shift and on days employees are scheduled to work, employees should self-monitor their symptoms by self-taking of temperature to check for fever and using the questions provided in this guidance (below) before reporting to work. It is important to note that control recommendations or interventions assigned to reduce the risk of spreading COVID-19 must be compatible with any safety programs and personal protective equipment (PPE) normally required for the job task. These devices produce relatively low levels of UV energy. • Screening will be performed by staff who have been trained on the screening protocol. If the machinery or equipment in question are not accessible to employees or have not been in contact with someone infected with COVID-19, they will not present an exposure hazard. If you’re looking for coronavirus screening questions to ask employees before each shift, you’ve come to the right place.

At a minimum, if you are considering the acquisition and use of these devices, you will want to be sure the equipment meets UL 867 standard certification (Standard for Electrostatic Air Cleaners) for production of acceptable levels of ozone, or preferably UL 2998 standard certification (Environmental Claim Validation Procedure (ECVP) for Zero Ozone Emissions from Air Cleaners) which is intended to validate that no ozone is produced. How long will it take to dilute the concentration of infectious particles in a room once they are generated? A critical infrastructure employee who is symptom-free and returns to work should wear a. However, the virus generally does not travel through the air by itself. By definition, a High Efficiency Particulate Air (HEPA) filter is at least 99.97% efficient at capturing particles 0.3 µm in size. Here are some of the screening questions included in the script: Have you or anyone in your household had any of the following symptoms in the last 21 days: sore throat, cough, chills, body aches for unknown reasons, shortness of breath for unknown reasons, loss of smell, loss of taste, fever at or greater than 100 degrees Fahrenheit? CDC and the Environmental Protection Agency (EPA) have jointly developed guidance for cleaning and disinfecting public spaces, including restrooms. Directional airflows must be evaluated carefully. Allowing flexible worksites (such as telework), Allowing flexible work hours (such as staggered shifts), Increasing physical space between employees at the worksite, Increasing physical space between employees and customers (such as a drive-through and partitions), Implementing flexible meeting and travel options (such as postponing non-essential meetings or events), Delivering services remotely (e.g., phone, video, or web), Delivering products through curbside pick-up or delivery. 1. These strategies include: In workplaces where it is not possible to eliminate face-to-face contact (such as retail), consider assigning employees who are at higher risk of severe illness work tasks that allow them to maintain a 6-foot distance from others, if feasible. The Centers for Disease Control and Prevention (CDC) has declared a shortage of PPD solution used for administering the TB Skin Test (TST). Screening employees is an optional strategy that employers may use. send an email request to eocevent106@cdc.gov and eocoht@cdc.gov. Employers should not require sick employees to provide a COVID-19 test result or a healthcare provider’s note to validate their illness, qualify for sick leave, or to return to work. If flying is necessary, select seats on flights that provide the greatest distance between other travelers and choose direct flights, if possible. A MERV 13 filter is at least 50% efficient at capturing particles in the 0.3 µm to 1.0 µm size range and 85% efficient at capturing particles in the 1 µm to 3 µm size range. Do you have any of the following respiratory symptoms? Maintain the indoor air temperature and humidity at comfortable levels for building occupants. 11. Employees should not return to work until they have met the criteria to discontinue home isolation and have consulted with a healthcare provider. The Families First Coronavirus Response Actexternal icon (FFCRA or Act) requires certain employers to provide their employees with paid sick leave or expanded family and medical leave for specified reasons related to COVID-19. Antibody test results should not be used to make decisions about returning persons to the workplace. The employee should put on a clean cloth face covering or disposable face mask. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. In the current pandemic, use of PPE such as surgical masks or N-95 respirators is being prioritized for healthcare employees and other medical first responders, as recommended by current CDC guidance unless they were required for the job before the pandemic. Different states and jurisdictions may have their own guidance and priorities for viral testing in workplaces. An example of an online ... How to screen for COVID-19 Ask these questions. Our screening questionnaire is based on the latest assessment questions available from public health officials in your jurisdiction (i.e. Some devices even include both technologies. Are under evaluation for COVID-19 (for example, waiting for the results of a viral test to confirm infection), Have been diagnosed with COVID-19 and not yet cleared to discontinue isolation, Fever or feeling feverish (chills, sweating), Ask the employee to confirm that their temperature is less than 100.4. Ideal for employers and businesses to start from our best practice questions and then modify them, remove some and add your own questions.. Research shows that the particle size of SARS-CoV-2, the virus that causes COVID-19, is around 0.1 micrometer (µm). First, clean dirty surfaces with soap and water. *Note: CDC’s recommendation for primary surface disinfection in occupied environments is to follow the CDC/EPA guidance for surface disinfection. However, reliance on PPE alone is a less effective control and more difficult to implement given PPE shortages and training requirements. What is the best way to do that? Did the study environments represent your environment and intended use? Employers should not require sick employees to provide a COVID-19 test result or healthcare provider’s note to validate their illness, qualify for sick leave, or return to work. Sick employees should follow CDC-recommended steps to help prevent the spread of COVID-19. The Department of Homeland Security developed a listexternal icon of essential critical infrastructure employees to help state and local officials as they work to protect their communities, while ensuring continuity of functions critical to public health and safety as well as economic and national security. Consumers should research the technology, attempting to match any specific claims against the intended use of the product. 2. Efficiencies for MERV 15 and MERV 16 filters are even higher. Wash hands often with soap and water for at least 20 seconds, especially after blowing noses. The addition of the HEPA filter device provides additional clean air to the room. Consider encouraging individuals planning to enter the workplace to self-screen prior to coming onsite and not to attempt to enter the workplace if any of the following are present: *A lower temperature threshold (e.g., 100.0oF) may be used, especially in healthcare settings. See CDC’s COVID-19 General Business FAQs for guidance on how to safely conduct employee screening. Should I require employees to provide a doctor’s note or positive COVID-19 test result? No .

Consider assigning a person to rotate throughout the workplace to clean and disinfect surfaces. To help employers screen their workers, the U.S. Chamber of Commerce created this questionnaire that can be completed in under five minutes each day. Some people may be at higher risk of severe illness. Ask the vendor to provide proof of effectiveness and performance that demonstrates a clear protective benefit. Although it is never the first line of prevention, consider general ventilation adjustments in your workplace, such as increasing ventilation and increasing the amount of outdoor air used by the system. How often should my employees wash their hands while at work? Using the mixing factor of 3, the estimated wait time for 99% reduction of airborne contaminants in the room is 3 x 23 = 69 minutes. Should we be screening employees for COVID-19 symptoms (such as temperature checks)? The cloth face covering should allow the wearer to breathe without restriction. endobj The larger the CADR, the faster it will clean the room air. As the coronavirus (COVID-19) pandemic continues, we are monitoring the situation closely and following the guidance from the Centers for Disease Control and Prevention and local health authorities. “Acute” respiratory illness is an infection of the upper or lower respiratory tract that may interfere with normal breathing, such as COVID-19. Unsubstantiated claims of performance or limited case studies with only one device in one room and no reference controls should be questioned. The clean volumetric air flow rate (Q) is the larger value between Qs and Qe, so Q = 72 cfm. Schedule travel to limit the distance travelled and need for overnight lodging. What is social distancing and how can my workplace do that? The risk of spreading the virus that causes coronavirus disease 2019 (COVID-19) through ventilation systems is not well-known at this time. If the cloth face covering becomes wet, visibly soiled, or contaminated at work, it should be removed and stored to be laundered later. Always wear gloves appropriate for the chemicals being used when you are cleaning and disinfecting. The EEOC explains that generally, measuring an employee’s body temperature is a medical examination, and as such, the Americans with Disabilities Act requires that the exam be “job-related and consistent with business necessity.” Should we be screening employees for COVID-19 symptoms (such as temperature checks)? If multi-day travel is necessary, coordinate with travel preparers to identify hotels that disinfect rooms between stays and regularly disinfect surfaces in common areas. Thus, the increased ACH and lower k value associated with the portable HEPA filtration unit reduced the wait time from the original 5 hours and 45 minutes to only 1 hour and 9 minutes, saving a total of 4 hours and 36 minutes before the room can be safely reoccupied. Do you have any of these symptoms that are not caused by another condition? Each day, before the start of the shift, ask each employee the following questions: 1. Where possible, avoid direct physical contact such as shaking hands with people.
