Occupational Safety and Health Administration (OSHA) (Alert, Guidance) and the Centers for Disease Control and Prevention (CDC) have issued workplace guidance to guide employers during the COVID-19 outbreak. They describe how employers should develop preparedness plans and communicate those plans to protect workers through effective training. Employers should assess worker exposure to hazards and risks and implement infection prevention measures to reasonably address them consistent with OSHA Standards. Such measures could include use of cloth face coverings; training workers on proper respiratory etiquette, physical distancing, and other steps they can take to protect themselves.
Employers may need to consider using stanchions to help keep workers and others at the worksite at least 6 feet away from each other. Installing temporary barriers and shields and spacing out workstations can also help achieve physical distancing recommendations. Employers should clean and disinfect frequently touched surfaces (e.g., door handles, sink handles, workstations, restroom stalls) at least daily, or as much as possible. Employers subject to OSHA's PPE standard must also provide and require the use of personal protective equipment (PPE) when needed. Job hazard assessments must be conducted to determine the appropriate type and level of PPE required.

What are the key differences between cloth face coverings, surgical masks, and respirators?
Surgical masks:
Respirators (e.g., filtering facepieces):
1 If surgical masks are being used only as source control—not to protect workers against splashes and sprays (i.e., droplets) containing potentially infectious materials—OSHA's PPE standards do not require employers to provide them to workers. However, the General Duty Clause, Section 5(a)(1) of the Occupational Safety and Health Act, requires each employer to furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm. Control measures may include a combination of engineering and administrative controls, including safe work practices like social distancing. Choosing to ensure use of surgical masks for source control may constitute a feasible means of abatement as part of a control plan designed to address hazards from SARS-CoV-2, the virus that causes COVID-19.

Are employers required to provide cloth face coverings to workers?
OSHA’s Mitigating and Preventing the Spread of COVID-19 in the Workplace advises employers to provide all workers with face coverings (i.e. cloth face coverings, surgical masks), unless their work task requires a respirator. Employers should provide face coverings to the workers at no cost. Employers must discuss the possibility of "reasonable accommodation" for any workers who are unable to wear or have difficulty wearing certain types of face coverings due to a disability. In workplaces with employees who are deaf or have hearing deficits, employers should consider acquiring masks with clear coverings over the mouth for all workers to facilitate lip-reading.
Cloth face coverings are not considered personal protective equipment (PPE) and are not intended to be used when workers need PPE for protection against exposure to occupational hazards. OSHA's PPE standards do not require employers to provide them.
No. Employers must not use surgical masks or cloth face coverings when respirators are needed.
In general, employers should always rely on a hierarchy of controls that first includes efforts to eliminate or substitute out workplace hazards and then uses engineering controls (e.g., ventilation, wet methods), administrative controls (e.g., written procedures, modification of task duration), and safe work practices to prevent worker exposures to respiratory hazards, before relying on personal protective equipment, such as respirators. When respirators are needed, OSHA's guidance describes enforcement discretion around use of respirators, including in situations in which it may be necessary to extend the use of or reuse certain respirators, use respirators beyond their manufacturer's recommended shelf life, and/or use respirators certified under the standards of other countries or jurisdictions.
The Centers for Disease Control and Prevention and OSHA have described crisis strategies intended for use in healthcare in which surgical masks or cloth face coverings may offer more protection than no mask at all when respirators are needed but are not available. Such information is not intended to suggest that surgical masks or cloth face coverings provide adequate protection against exposure to airborne contaminants for which respirators would ordinarily be needed. Although OSHA's enforcement guidance describes equipment prioritization that includes surgical masks, employers must still comply with the provisions of any standards that apply to the types of exposures their workers may face. For example, the permissible exposure limits of all substance-specific standards, such as asbestos and silica, remain in place, and surgical masks are not an acceptable means of protection when respirators would otherwise be required (e.g., when engineering, administrative, and work practice controls do not sufficiently control exposures).
If respirators are needed but not available (including as described in the OSHA enforcement guidance noted above), and hazards cannot otherwise be adequately controlled through other elements of the hierarchy of controls (i.e., elimination, substitution, engineering controls, administrative controls, and/or safe work practices), avoid worker exposure to the hazard. Whenever a hazard presents an imminent danger, and in additional situations whenever feasible, the task should be delayed until feasible control measures are available to prevent exposures or reduce them to acceptable levels (i.e., at or below applicable OSHA permissible exposure limits).
No. Medical masks, including surgical masks, are routinely worn by healthcare workers throughout the day as part of their personal protective equipment (PPE) ensembles and do not compromise their oxygen levels or cause carbon dioxide buildup. They are designed to be breathed through and can protect against respiratory droplets, which are typically much larger than tiny carbon dioxide particles. Consequently, most carbon dioxide particles will either go through the mask or escape along the mask's loose-fitting perimeter. Some carbon dioxide might collect between the mask and the wearer's face, but not at unsafe levels.
Like medical masks, cloth face coverings are loose-fitting with no seal and are designed to be breathed through. In addition, workers may easily remove their medical masks or cloth face coverings periodically (and when not in close proximity with others) to eliminate any negligible build-up of carbon dioxide that might occur. Cloth face coverings and medical masks can help prevent the spread of potentially infectious respiratory droplets from the wearer to their co-workers, including when the wearer has COVID-19 and does not know it.
Some people have mistakenly claimed that OSHA standards (e.g., the Respiratory Protection standard, 29 CFR 1910.134; the Permit-Required Confined Space standard 29 CFR 1910.146; and the Air Contaminants standard, 29 CFR 1910.1000) apply to the issue of oxygen or carbon dioxide levels resulting from the use of medical masks or cloth face coverings in work settings with normal ambient air (e.g. healthcare settings, offices, retail settings, construction). These standards do not apply to the wearing of medical masks or cloth face coverings in work settings with normal ambient air). These standards would only apply to work settings where there are known or suspected sources of chemicals (e.g., manufacturing facilities) or workers are required to enter a potentially dangerous location (e.g., a large tank or vessel).
Has OSHA changed its respiratory protection requirements for the construction industry?
No. All OSHA requirements for respiratory protection in construction that were in place before the COVID-19 pandemic remain in place. Under OSHA's Respiratory Protection standard for construction (29 CFR 1926.103), employers must follow 29 CFR 1910.134 the general industry respiratory protection standard. Similarly, employers must continue to follow requirements in other OSHA standards, including those that require respiratory protection to protect workers from exposures to certain chemicals and other hazardous substances.
OSHA recognizes that employers and workers in construction may not always be able to get the personal protective equipment they need because of shortages during the COVID-19 pandemic. OSHA is providing temporary enforcement discretion around the requirements of certain standards, including the Respiratory Protection standard (29 CFR 1910.134). The enforcement guidance describes criteria for enforcement discretion when employers make good-faith efforts to get National Institute for Occupational Safety and Health (NIOSH)–certified N95 filtering facepiece respirators or other appropriate NIOSH-certified respirators and are unable to do so.
NIOSH guidance describes options for extended use and reuse of respirators, using expired respirators or respirators certified under the standards of other countries or jurisdictions, and other options for protecting workers who need respirators on the job. More information is available in the COVID-19 enforcement guidance on the Enforcement Memos page. Employers should regularly check the Standards page of OSHA's COVID-19 Safety and Health Topics page for updates on the status of these memoranda.
The Centers for Disease Control and Prevention (CDC) and OSHA are providing extensive guidance for infection prevention in healthcare settings.
Both agencies' guidance materials describe how healthcare employers should develop and implement infection control and preparedness plans and communicate those plans to workers through effective training. Employers should assess the risks and follow the hierarchy of controls for worker protection:
For information on protecting healthcare workers from exposure to SARS-CoV-2, the virus that causes COVID-19, please see:
OSHA recommends that, during the ongoing pandemic and associated community spread of COVID-19, all workers wear face coverings to prevent the spread of their respiratory particles. This is because people can spread SARS-CoV-2, the virus that causes COVID-19, by coughing, sneezing, or talking—even if they do not feel sick. Because of other exposures in healthcare settings, healthcare workers may need to wear surgical masks to prevent or reduce the risk of this transmission, while also protecting themselves from exposure to patients' potentially infectious respiratory particles and other splashes or sprays of body fluids.
Healthcare workers and employers should also consult OSHA and CDC guidance to find out if they need additional types of personal protective equipment. OSHA recommends that healthcare workers with exposure to suspected or confirmed COVID-19 patients wear PPE ensembles that include N95 or better filtering facepiece respirators. The combination of surgical masks with face shields or goggles can reduce the risk of exposure to the virus when caring for people who may spread COVID-19 without knowing they have it. For some activities, including aerosol-generating procedures, healthcare workers likely need N95 or better filtering facepieces respirators. N95 or better respirators should be used in accordance with a respiratory protection program.
The Centers for Disease Control and Prevention (CDC) describes the appropriate biosafety level (BSL) protection for various types of tasks in its Interim Guidelines for Collecting, Handling, and Testing Clinical Specimens for COVID-19 and Interim Laboratory Biosafety Guidelines for Handling and Processing Specimens Associated with COVID-19.
In general, CDC recommends that for:
For viral testing of specimens conducted outside of a BSL-2 laboratory, such as rapid respiratory testing performed at the point of care, use standard precautions to provide a barrier between the specimen and personnel during specimen manipulation. For more information on specimen collection, handling, and testing, refer to the CDC's Interim Guidelines for Collecting, Handling, and Testing Clinical Specimens for COVID-19.
Aerosol-generating procedures and work with concentrated virus should always be performed in an appropriately maintained and certified biosafety cabinet.
OSHA also discusses laboratory biosafety on its COVID-19 Safety and Health Topics page. This guidance is generally consistent with CDC's Biosafety in Microbiological and Biomedical Laboratories (BMBL), 5th Edition.
OSHA has issued temporary enforcement guidance for the Respiratory Protection standard (29 CFR 1910.134) for:
OSHA enforcement guidance describes additional measures employers can take to ensure workers have appropriate respiratory protection during the COVID-19 pandemic.
Although OSHA's enforcement guidance describes equipment prioritization that includes surgical masks as potential considerations in some circumstances when respirators are not available, employers must still comply with the provisions of any standards that apply to the types of exposures their workers may face. For example, the permissible exposure limits of all substance-specific standards, such as asbestos and silica, remain in place, and surgical masks are not an acceptable means of protection when respirators would otherwise be required (e.g., when engineering, administrative, and work practice controls do not sufficiently control exposures).
If respirators are needed but not available (including as described in the OSHA enforcement guidance noted above), and hazards cannot otherwise be adequately controlled through other elements of the hierarchy of controls (i.e., elimination, substitution, engineering controls, administrative controls, and/or safe work practices), avoid worker exposure to the hazard. Whenever a hazard presents an imminent danger, and in additional situations whenever feasible, the task should be delayed until feasible control measures are available to prevent exposures or reduce them to acceptable levels (i.e., at or below applicable OSHA permissible exposure limits).
The CDC/National Institute for Occupational Safety and Health, National Personal Protective Technology Laboratory (NPPTL), provides additional information on SARS-CoV-2, the virus that causes COVID-19, and PPE.
If there are no workers at your physical establishment on February 1, 2021 due to COVID-19, you do not need to post the OSHA 300-A Summary of Work-related Injuries and Illnesses. If your workplace subsequently opens and employees return to the establishment before May 1, 2021, you must post your OSHA 300-A Summary of Work-related Injuries and Illnesses in a conspicuous place or places where notices to employees are customarily posted until May 1, 2021.
OSHA believes informing employees of work-related injuries and illnesses that occur at their workplace is an essential component of a good safety and health program. While you are not required to do so, electronically sharing Form 300-A with your employees would prove beneficial even if there are no employees currently onsite.
Will an N95 respirator protect the wearer from the virus that causes COVID-19?
Yes, an N95 respirator is effective in protecting workers from the virus that causes COVID-19. "N95" refers to a class of respirator filter that removes at least 95% of very small (0.3 micron) particles from the air. Some people have mistakenly claimed that since the virus that causes COVID-19 is approximately 0.1 microns in size, wearing an N95 respirator will not protect against such a small virus. That mistaken claim appears to result from a misunderstanding of how respirators work.
When an infected person expels the virus into the air by activities like talking, coughing, or sneezing, the airborne particles are composed of more than just the virus. The virus is part of larger particles that are made up of water and other materials such as mucus. These larger particles are easily trapped and filtered out by N95 respirators because they are too big to pass through the filter. This is called mechanical filtration. But mechanical filtration is just one of the ways that respirator filters keep particles from passing through the filter. An electrostatic charge also attracts particles to fibers in the filter, where the particles become stuck. In addition, the smallest particles constantly move around (called "Brownian motion"), and are very likely to hit a filter fiber and stick to it.
The National Institute for Occupational Safety and Health (NIOSH) tests respirators using particles that simulate a 0.3 micron diameter because this size particle is most likely to pass through the filter. If worn correctly, the N95 respirator will filter out at least 95% of particles this size. An N95 respirator is more effective at filtering particles that are smaller or larger than 0.3 microns in size.
The N95 respirator filter, as is true for other NIOSH-approved respirators, is very effective at protecting people from the virus causing COVID-19. However, it is important for employers and workers to remember that the respirator only provides the expected protection when used correctly. Respirators, when required, must be used as part of a comprehensive, written respiratory protection program that meets the requirements of OSHA's Respiratory Protection standard. The program should include medical evaluations, training, and fit testing.
Under 29 CFR 1904.39(b)(6), employers are only required to report in-patient hospitalizations to OSHA if the hospitalization "occurs within twenty-four (24) hours of the work-related incident." For cases of COVID-19, the term "incident" means an exposure to SARS-CoV-2 in the workplace. Therefore, in order to be reportable, an in-patient hospitalization due to COVID-19 must occur within 24 hours of an exposure to SARS-CoV-2 at work. The employer must report such hospitalization within 24 hours of knowing both that the employee has been in-patient hospitalized and that the reason for the hospitalization was a work-related case of COVID-19. Thus, if an employer learns that an employee was in-patient hospitalized within 24 hours of a work-related incident, and determines afterward that the cause of the in-patient hospitalization was a work-related case of COVID-19, the case must be reported within 24 hours of that determination. See 29 CFR 1904.39(a)(2), (b)(7)-(b)(8).
Employers should note that 29 CFR 1904.39(b)(6)'s limitation only applies to reporting; employers who are required to keep OSHA injury and illness records must still record work-related confirmed cases of COVID-19, as required by 29 CFR 1904.4(a). For more information on recording cases of COVID-19, see https://www.osha.gov/memos/2020-05-19/revised-enforcement-guidance-recording-cases-coronavirus-disease-2019-covid-19.
Under 29 CFR 1904.39(b)(6), an employer must "report a fatality to OSHA if the fatality occurs within thirty (30) days of the work-related incident." For cases of COVID-19, the term "incident" means an exposure to SARS-CoV-2 in the workplace. Therefore, in order to be reportable, a fatality due to COVID-19 must occur within 30 days of an exposure to SARS-CoV-2 at work. The employer must report the fatality within eight hours of knowing both that the employee has died, and that the cause of death was a work-related case of COVID-19. Thus, if an employer learns that an employee died within 30 days of a work-related incident, and determines afterward that the cause of the death was a work-related case of COVID-19, the case must be reported within eight hours of that determination.
Employers should note that 29 CFR 1904.39(b)(6)'s limitation only applies to reporting; employers who are required to keep OSHA injury and illness records must still record work-related fatalities, as required by 29 CFR 1904.4(a). For more information on recording cases of COVID-19, see https://www.osha.gov/memos/2020-05-19/revised-enforcement-guidance-recording-cases-coronavirus-disease-2019-covid-19.
Section 11(c) of the Occupational Safety and Health Act of 1970 (29 USC 660(c)) prohibits employers from retaliating against workers for exercising a variety of rights guaranteed under the law, such as filing a safety or health complaint with OSHA, raising a health and safety concern with their employers, participating in an OSHA inspection, or reporting a work-related injury or illness. Additionally, OSHA's Whistleblower Protection Program enforces the provisions of more than 20 industry-specific federal laws protecting employees from retaliation for raising or reporting concerns about hazards or violations of various airline, commercial motor carrier, consumer product, environmental, financial reform, food safety, health insurance reform, motor vehicle safety, nuclear, pipeline, public transportation agency, railroad, maritime, securities, and tax laws.
If you believe you have suffered such retaliation, submit a complaint to OSHA as soon as possible in order to ensure that you file the complaint within the legal time limits, some of which may be as short as 30 days from the date you learned of or experienced retaliation. An employee can file a complaint with OSHA by visiting or calling his or her local OSHA office; sending a written complaint via fax, mail, or email to the closest OSHA office; or filing a complaint online. No particular form is required and complaints may be submitted in any language.
Visit OSHA's Whistleblower Protection Program website for more information.
What should employers do when an employee tests positive for COVID-19?
Workers who test positive for COVID-19 will be notified of their results by their healthcare providers or public health department and will likely be advised to self-isolate or seek medical care. OSHA recommends that workers tell their supervisors if they have tested positive for COVID-19 so that employers can take steps, such as cleaning and disinfection, to protect other workers. Employers who become aware of a case among their workers should:
OSHA does not require employers to notify other employees if one of their coworkers gets COVID-19. However, employers must take appropriate steps to protect other workers from exposure to SARS-CoV-2, the virus that causes COVID-19, in the workplace. These steps might include specific actions as a result of a confirmed case, such as cleaning and disinfecting the work environment, notifying other workers to monitor themselves for signs/symptoms of COVID-19, or implementing a screening program in the workplace (e.g., for signs/symptoms of COVID-19 among workers).
The CDC Guidance for Business and Employers recommends employers determine which employees may have been exposed to the virus and inform employees of their possible exposure to COVID-19 in the workplace. However, employers should maintain confidentiality as required by the Americans with Disabilities Act (ADA), and the information disclosed and method of disclosure must comply with applicable federal, state, and local laws.
Employers and workers can visit the U.S. Equal Employment Opportunity Commission's COVID-19 webpage and frequently asked questions to learn more about this topic.
What topics should employers cover in COVID-19 training for workers?
During the COVID-19 pandemic, employers should consider training workers about:
Some OSHA standards require employers to provide specific training to workers. For example, there are training requirements in OSHA's PPE standards (29 CFR Part 1910, Subpart I), including the Respiratory Protection standard (29 CFR 1910.134).
The training that is necessary can vary depending on a worker's job tasks, exposure risks, and the type of controls implemented to protect workers. See OSHA's COVID-19 Safety and Health Topics page for more specific information.
No. Although adverse reactions to recommended COVID-19 vaccines may be recordable under 29 CFR 1904.4(a) if the reaction is: (1) work-related, (2) a new case, and (3) meets one or more of the general recording criteria in 29 CFR 1904.7, OSHA is exercising its enforcement discretion to only require the recording of adverse effects to required vaccines at this time. Therefore, you do not need to record adverse effects from COVID-19 vaccines that you recommend, but do not require.
Note that for this discretion to apply, the vaccine must be truly voluntary. For example, an employee’s choice to accept or reject the vaccine cannot affect their performance rating or professional advancement. An employee who chooses not to receive the vaccine cannot suffer any repercussions from this choice. If employees are not free to choose whether or not to receive the vaccine without fearing adverse action, then the vaccine is not merely “recommended” and employers should consult the above FAQ regarding COVID-19 vaccines that are a condition of employment.
Note also that the exercise of this discretion is intended only to provide clarity to the public regarding OSHA’s expectations as to the recording of adverse effects during the health emergency; it does not change any of employers’ other responsibilities under OSHA’s recordkeeping regulations or any of OSHA’s interpretations of those regulations.
Finally, note that this answer applies to a variety of scenarios where employers recommend, but do not require vaccines, including where the employer makes the COVID-19 vaccine available to employees at work, where the employer makes arrangements for employees to receive the vaccine at an offsite location (e.g., pharmacy, hospital, local health department, etc.), and where the employer offer the vaccine as part of a voluntary health and wellness program at my workplace. In other words, the method by which employees might receive a recommended vaccine does not matter for the sake of this question.
Under federal law, you are entitled to a safe workplace. Your employer must provide a workplace free of known health and safety hazards. If you have concerns, you have the right to speak up about them without fear of retaliation.
If you believe you are being exposed to SARS-CoV-2, the virus that causes COVID-19, or that your employer is not taking appropriate steps to protect you from exposure to the virus at work, talk to your supervisor or employer about your concerns. OSHA provides recommendations for measures workers and employers can take to prevent exposures and infections.
You have the right to file a complaint if you feel you are being exposed to a serious health or safety hazard. If you have suffered retaliation because you voiced concerns about a health or safety hazard, you have the right to file a whistleblower protection complaint.
If you believe you have contracted COVID-19 on the job, OSHA recommends several steps you should take, including notifying your supervisor. Your employer can take actions that will keep others in your workplace healthy and may be able to offer you leave flexibilities while you are away from work.

Generally, your employer may require you to come to work during the COVID-19 pandemic. However, some government emergency orders may affect which businesses can remain open during the pandemic.
Under federal law, you are entitled to a safe workplace. Your employer must provide a safe and healthful workplace. If you have concerns, you have the right to speak up about them without fear of retaliation.
Under section 11(c) of the Occupational Safety and Health Act, a worker who refused to work would be protected from retaliation if:

You have the right to file a complaint if you are required to work and believe you are being exposed to a serious health or safety hazard. If you have suffered retaliation because you voiced concerns about a health or safety hazard, you have the right to file a whistleblower protection complaint. No particular form is required and complaints may be submitted in any language.
Visit OSHA's Workers page to learn more.
If you believe that your health and safety are in danger, you (or your representative) have the right to file a confidential safety and health complaint with OSHA.
Employers should strive to maintain a sufficient supply of sanitation and hygiene products such as soap or hand sanitizer with at least 60% alcohol to use when soap and water are not available. Handwashing is an important measure for staying safe. If your workplace is running low, speak to your supervisor about ensuring more is provided.
If soap is not available, CDC recommends using a hand sanitizer with at least 60% alcohol. Wear gloves, if needed. Don't touch your nose, mouth, eyes, face, or food with unwashed hands or while wearing gloves. OSHA's sanitation standards (29 CFR 1910.141, 29 CFR 1926.51, 29 CFR 1928.110, 29 CFR 1915.88, and 29 CFR 1917.127) are intended to ensure that workers do not suffer adverse health effects that can result if handwashing facilities and supplies and toilets are not sanitary or available when needed
