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. If soap and water are not available, use hand sanitizer that contains at least 60% alcohol. Unless otherwise specified, the CDC interim guidance for businesses and employers applies to critical infrastructure workplaces as well. Consider options to increase physical space between employees in work areas and between employees and customers such as opening a drive-through, erecting partitions, and marking floors to guide spacing at least 6 feet apart. Employees may have been exposed if they are a “close contact” of someone who is infected, which is defined as being within about 6 feet of a person with COVID-19 for a prolonged period of time: All other employees should self-monitor for symptoms and wear cloth face coverings when in public. Functioning critical infrastructurepdf iconexternal icon is imperative during the response to the COVID-19 emergency, for both public health and safety as well as community well-being. For this reason, source control measures should be implemented for everyone in the facility, regardless of symptoms. How much time is required to reduce the airborne particle concentration by 99 percent? 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. before you start your shift and after you complete each shift. COVID-19 Employee Screening Questionnaire Screening employees daily can help in preventing the spread of the coronavirus in the workplace. Be sure to seek consultation with a reputable GUV manufacturer or an experienced GUV system designer prior to installing GUV systems. Does germicidal ultraviolet (GUV) disinfection kill the virus that causes COVID-19? HEPA fan systems can be used as stand-alone units, or many larger units allow flexible ductwork to be attached to the air inlet and/or outlet (note that larger ducted units don’t fall under the “room air cleaner” description and may not have a CADR rating). If soap and water are not available, they should use a hand sanitizer with at least 60% alcohol. Consider including these symptoms: There are several methods that employers can use to protect the employee conducting the screening. This can lead to increased fan energy, reduced airflow rates, and/or issues controlling indoor temperature and relative humidity levels. The following applies to both State employees and contracted staff working on behalf of the State. Portable HEPA filtration units that combine a HEPA filter with a powered fan system are a great option for auxiliary air cleaning, especially in higher risk settings such as health clinics, medical testing locations, workout rooms, or public waiting areas. Source control is a term used to describe measures (e.g., cloth face coverings or face shields) intended to prevent people with COVID-19 from spreading the disease to others. Employers can lawfully conduct temperature checks of employees entering the workplace. <> Provide training and other administrative policies to prevent the spread of COVID-19. Have conversations with employees if they express concerns. The CDC considers a person to have a fever when he or she has a measured temperature of at least 100.4 degrees Fahrenheit; many employers have adopted screening thresholds in the 100-100.4°F range. However, outside of a few unique applications, HEPA filters are rarely used in central HVAC systems. Healthcare provider offices and medical facilities may be extremely busy and not able to provide such documentation in a timely manner. 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. 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. Thus, conservative estimates of k are often used (as described above). Note: Question A.6 and A.8 address screening of employees generally. An analysis of core job tasks and workforce availability at worksites can allow the employer to match core activities to other equally skilled and available in-person employees who have not been exposed. Aside from the wavelength, a major difference between the two technologies is that standard GUV systems are specifically designed to avoid exposing people to the UV energy, while many far-UV devices are marketed as safe for exposing people and their direct environment to UV energy. Employers should develop a plan for routine cleaning and disinfection, including the regular cleaning and disinfection of high-touch surfaces such as doorknobs, faucets, toilets, and other restroom furnishings. Cloth face coverings and face shields are types of source control that provide a barrier between droplets produced from a potentially infected person and other people, reducing the likelihood of transmitting the virus. However, in the absence of an established body of peer-reviewed evidence showing proven efficacy and safety under as-used conditions, the technologies are still considered by many to be “emerging.” As with all emerging technologies, consumers are encouraged to exercise caution and to do their homework. The ongoing COVID-19 pandemic has prompted not only the U.S. federal government, but also all of the individual state governments, to act quickly to slow the spread of the coronavirus and save lives. Are cloth face coverings the same as personal protective equipment (PPE)? Thus, HEPA filters are no less than 99.97% efficient at capturing human-generated viral particles associated with SARS-CoV-2.

The questionnaire consists of six questions broken into three sections: questions to be asked upon return to work, to be asked weekly, and to be asked daily. The guidance notes that employers may lawfully conduct temperature screening and COVID-19 testing during the pandemic. *Note: CDC’s recommendation for primary surface disinfection in occupied environments is to follow the CDC/EPA guidance for surface disinfection. Consider focusing the screening questions on “new” or “unexpected” symptoms (e.g., a chronic cough would not be a positive screen). 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. Testing of the directional airflow effectiveness can be accomplished using visual tracer techniques that use “smoke tubes” or handheld “fog generators.” Other tools, such electronic monitors or visual aids to monitor pressure differences can be used when directional airflow is established between two adjacent spaces. If they are unable to remove it without help. %PDF-1.7 Dilution ventilation and particle filtration are commonly used to remove these smaller particles from the air. * Definitions represent CDC-designated guidance and symptoms of COVID-19 at the time of drafting. Facility waste does not need disinfection. However, perfect mixing usually does not occur. Screening employees is an optional strategy that employers may use. CDC suggests checking employees’ temperatures daily in Silicon Valley and Seattle San Jose, the seat of Santa Clara County, which has seen 45 … Your health and well-being are of the upmost importance and we are taking measures to keep the facility/office a safe environment for employees as well as the individuals under our charge and the public. The CDC also states that screening employees is an optional strategy that employers may use to prevent the spread of the virus. Critical infrastructure businesses have an obligation to limit, to the extent possible, the reintegration of in-person employees who have experienced an exposure to COVID-19 but remain symptom-free in ways that best protect the health of the employee, their co-employees, and the general public. There may be some implications for HVAC systems associated with these findings, but it is too early to conclude that with certainty. Isolate hard (non-porous) surfaces that cannot be cleaned and disinfected for a minimum of 7 days before handling. What is symptom screening? These Guidelines and Procedures MUST be implemented at all times on all construction sites. 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. Do you have any of the following respiratory symptoms? This can be done passively, through intentional placement of supply and exhaust heating, ventilation, and air conditioning (HVAC) grills or by the intentional creation of pressure differentials between adjacent spaces through specification of offset exhaust and supply air flow rates. Isolate papers or any soft (porous) surfaces for a minimum of 24 hours before handling. If you answer “yes” to any of the following questions, please contact HR about reasonable accommodations or alternative work options. When wearing a cloth face covering, it should fit over the nose and mouth, fit snugly but comfortably against the side of the face, and be secured with ties or ear loops. How much time is saved to achieve the same 99% reduction in airborne contaminants by adding the portable HEPA device to the room? Screening will not identify people not showing symptoms yet, or who may be infected but Encourage staff and attendees to stay home if sick. 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. CDC Guidance on Screening Employees for Temperature and Symptoms. Make a visual inspection of the employee for signs of illness, which could include flushed cheeks or fatigue, and confirm that the employee is not experiencing coughing or shortness of breath. Employee Name: Please complete this form. By using strategies that help prevent the spread of COVID-19 in the workplace, you will help protect all employees, including those at higher risk. Social distancing means avoiding large gatherings and maintaining distance (at least 6 feet) from others when possible. However, the virus generally does not travel through the air by itself. Are there independent studies that prove the desired performance of the technology? The questions on the Sample Health Screening Tool (Page 2) are designed to help determine Critical infrastructure employees who have been exposed but remain symptom-free and must return to in-person work should adhere to the following practices before and during their work shift: Employees with symptoms should be sent home and should not return to the workplace until they have met the criteria to discontinue home isolation. To be protective and not introduce an additional hazard, the use of PPE requires characterization of the environment, knowledge of the hazard, training, and consistent correct use. Engage with a ventilation engineer, and if the engineer recommends installing such a system, obtain a guarantee as to expected disinfection performance. COVID-19 Screening Checklist for Non-Medical Employers All employees and visitors entering the building should be asked following questions. Consider scheduling a relief person to give cashiers and service desk employees an opportunity to wash their hands. If you’re looking for coronavirus screening questions to ask employees before each shift, you’ve come to the right place. Coronavirus 2019 (COVID-19): Sample Health Screening Tool This document is intended for workplaces and establishments as they implement COVID-19 screening procedures as a universal safeguard to help keep employees, visitors, and patrons safe. Efficiencies for MERV 15 and MERV 16 filters are even higher. However, if an employer does chose to screen employees returning to work, the employer should take steps to protect both the individual being screened and the individual performing the screening. Minimize handling cash, credit cards, and mobile or electronic devices when possible. What does “acute” respiratory illness mean? Critical infrastructure employees should follow, Employees not considered exposed should self-monitor for. CDC has created frequently asked questions that can be used to inform risk assessment for patients and visitors exposed to SARS-CoV-2 in a healthcare setting. Fever of 100.4 °F or greater New or worsening cough in the last 48 hours Shortness of breath that started in the last 48 hours Sore throat What are types of germicidal ultraviolet (GUV) for cleaning and disinfection in the workplace? However, reintegrating exposed, asymptomatic employees to onsite operations, while discussed in the critical infrastructure guidance, should not be misinterpreted as always being the first or most appropriate option to pursue in managing critical work tasks. Follow CDC guidance for events and mass gatherings and consider resuming non-essential travel in accordance with state and local regulations and guidance. Other settings that could benefit from portable HEPA filtration can be identified using typical risk assessment parameters, such as community incidence rates, facemask compliance expectations and room occupant density. Sick employees should follow steps to prevent the spread of COVID-19. 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. Here, the clean volumetric air flow rate (Q) is:  Q = Qe + Qhepa = 72 cfm + 145 cfm = 217 cfm. Sick employees should follow CDC-recommended steps to help prevent the spread of COVID-19. 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. ACH = [Q x 60] / (room volume) = (217 cfm x 60) / (12’ x 10’ x 9’) = 13,020/1080 = 12.06 ACH (round down to 12). For more information, visit CDC’s Resources for Businesses and Employers. However, a reputable GUV manufacturer or an experienced GUV system designer should know the precautionary techniques to prevent harmful UV exposures to people in the space. Make sure employees know who to contact if they are sick. The prevalence of Zika virus infection in many countries has decreased dramatically since 2017, and, as a result, the likelihood of a false-positive test result has increased. Wait 24 hours before cleaning and disinfecting to minimize potential for exposure to respiratory droplets. [. In-duct GUV systems are installed within a heating, ventilation, and air-conditioning (HVAC) system. High-efficiency particulate air (HEPA) filters are even more efficient at filtering human-generated infectious particles than MERV 16 filters. For example, redesign workstations so employees are not facing each other. SwipedOn’s visitor management solution can seamlessly manage contactless employee health screenings to protect staff and workplaces from the risk of exposure to serious diseases. 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. Directional Airflow is a protective ventilation concept where air movement flows in a clean-to-less-clean direction. If I shut down my facility as a result of a COVID-19 case or outbreak, what is the recommended way to clean and disinfect, and what is the appropriate timeframe to resume operations? Employee Health Screening Form . Coil treatment GUV keeps HVAC coils, drain pans, and wetted surfaces free of microbial growth. Since the 1980s, GUV systems have been widely used for control of tuberculosis (TB). 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. Employees who have symptoms when they arrive at work or become sick during the day should immediately be separated from other employees, customers, and visitors and sent home. Cloth face coverings are intended to protect other people—not the wearer. Additional personal protective equipment (PPE) may be needed based on the setting and product you are using. Filters for use in heating, ventilation, and air conditioning (HVAC) systems are generally tested under procedures outlined in ANSI/ASHRAE Standard 52.2-2017-Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size. 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. HEPA filters are even more efficient at capturing particles larger and smaller than the MPPS. In general, cloth face coverings should be washed regularly (e.g., daily after each shift) using water and a mild detergent and dried completely in a hot dryer. Employees with COVID-19 who have stayed home can stop home isolation and return to work when they have met one of the sets of criteria found here. It has a series of questions and recommends what level of medical care, if any, the user should seek. 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. If a washing machine and dryer are not available, an alternative is to soak the cloth face covering in a diluted bleach (0.1%) solution, rinse, and air dry completely. If storing the cloth face covering while at work, employees should place the used cloth face covering into a container or paper bag labeled with the employee’s name. Evidence suggests that people who have mild symptoms or no symptoms can spread it to others without realizing they are infected. Saving Lives, Protecting People. 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.” After each screening or after several screenings, where you did not have physical contact with an individual, remove and discard PPE and wash hands with soap and water for at least 20 seconds or use hand sanitizer with at least 60% alcohol.
