Control and Prevention

Measures for protecting workers from exposure to, and infection with, the novel coronavirus, COVID-19 depend on the type of work being performed and exposure risk, including potential for interaction with infectious people and contamination of the work environment. Employers should adapt infection control strategies based on a thorough hazard assessment, using appropriate combinations of engineering and administrative controls, safe work practices, and personal protective equipment (PPE) to prevent worker exposures. Some OSHA standards that apply to preventing occupational exposure to COVID-19 also require employers to train workers on elements of infection prevention, including PPE.

OSHA has developed this interim guidance to help prevent worker exposure to COVID-19.

Regardless of specific exposure risks, following good hand hygiene practices can help workers stay healthy year round.

General guidance for all U.S. workers and employers

For all workers, regardless of specific exposure risks, it is always a good practice to:

Frequently wash your hands with soap and water for at least 20 seconds. When soap and running water are unavailable, use an alcohol-based hand rub with at least 60% alcohol. Always wash hands that are visibly soiled.
Avoid touching your eyes, nose, or mouth with unwashed hands.
Avoid close contact with people who are sick.

The U.S. Centers for Disease Control and Prevention has developed interim guidance for businesses and employers to plan for and respond to COVID-19. The interim guidance is intended to help prevent workplace exposures to acute respiratory illnesses, including COVID-19. The guidance also addresses considerations that may help employers prepare for more widespread, community outbreaks of COVID-19, in the event that this kind of transmission begins to occur. The guidance is intended for non-healthcare settings; healthcare workers and employers should consult guidance specific to them, below.
Interim guidance for most U.S. workers and employers of workers unlikely to have occupational exposures to COVID-19

For most people in the United States, including most types of workers, the risk of infection with COVID-19 is currently low. This applies to U.S. workers not discussed elsewhere on this page (i.e., those not involved in healthcare, deathcare, laboratory, airline, border protection, or solid waste and wastewater management operations or international travel to areas with ongoing, person-to-person transmission of COVID-19). Such workers’ exposure risk is similar to that of the general American public.

Employers and workers in operations where there is no specific exposure hazard should remain aware of the evolving outbreak situation. Changes in outbreak conditions may warrant additional precautions in some workplaces not currently highlighted in this guidance.

OSHA’s infection prevention recommendations follow the hierarchy of controls, including using engineering and administrative controls and safe work practices to protect workers from exposure to COVID-19. Depending on work tasks and potential exposures, appropriate PPE for protecting workers from the virus may include gloves, gowns, masks, goggles or face shields, and/or respirators.
Interim guidance for U.S. workers and employers of workers with potential occupational exposures to COVID-19

Workers and employers involved in healthcare, deathcare, laboratory, airline, border protection, and solid waste and wastewater management operations and international travel to areas with ongoing, person-to-person transmission of COVID-19 should remain aware of the evolving outbreak situation.

As discussed on the Hazard Recognition page, employers should assess the hazards to which their workers may be exposed; evaluate the risk of exposure; and select, implement, and ensure workers use controls to prevent exposure. Control measures may include a combination of engineering and administrative controls, safe work practices, and PPE.

Identify and Isolate Suspected Cases

In all workplaces where exposure to the COVID-19 may occur, prompt identification and isolation of potentially infectious individuals is a critical first step in protecting workers, visitors, and others at the worksite.

Immediately isolate people suspected of having COVID-19. For example, move potentially infectious people to isolation rooms and close the doors. On an aircraft, move potentially infectious people to seats away from passengers and crew, if possible and without compromising aviation safety. In other worksites, move potentially infectious people to a location away from workers, customers, and other visitors.
Take steps to limit spread of the person’s infectious respiratory secretions, including by providing them a facemask and asking them to wear it, if they can tolerate doing so. Note: A surgical mask on a patient or other sick person should not be confused with PPE for a worker; the mask acts to contain potentially infectious respiratory secretions at the source (i.e., the person’s nose and mouth).
If possible, isolate people suspected of having COVID-19 separately from those with confirmed cases of the virus to prevent further transmission, including in screening, triage, or healthcare facilities.
Restrict the number of personnel entering isolation areas, including the room of a patient with suspected/confirmed COVID-19.
Protect workers in close contact* with the sick person by using additional engineering and administrative control, safe work practices and PPE.

*CDC defines “close contact” as being about six (6) feet (approximately two (2) meters) from an infected person or within the room or care area of an infected patient for a prolonged period while not wearing recommended PPE. Close contact also includes instances where there is direct contact with infectious secretions while not wearing recommended PPE. Close contact generally does not include brief interactions, such as walking past a person.

Environmental Decontamination

At this time, there is no evidence that the COVID-19 is spread through environmental exposures, such as coming into contact with contaminated surfaces.

Because the transmissibility of COVID-19 from contaminated environmental surfaces and objects is not fully understood, employers should carefully evaluate whether or not work areas occupied by people suspected to have virus may have been contaminated and whether or not they need to be decontaminated in response.

Workers who conduct cleaning tasks must be protected from exposure to blood, certain body fluids, and other potentially infectious materials covered by OSHA’s Bloodborne Pathogens standard (29 CFR 1910.1030) and from hazardous chemicals used in these tasks. In these cases, the PPE (29 CFR 1910 Subpart I) and Hazard Communication (29 CFR 1910.1200) standards may also apply. Do not use compressed air or water sprays to clean potentially contaminated surfaces, as these techniques may aerosolize infectious material.

See the interim guidance for specific worker groups and their employers, below, for further information.

Worker Training

Train all workers with reasonably anticipated occupational exposure to COVID-19 (as described in this document) about the sources of exposure to the virus, the hazards associated with that exposure, and appropriate workplace protocols in place to prevent or reduce the likelihood of exposure. Training should include information about how to isolate individuals with suspected or confirmed COVID-19 or other infectious diseases, and how to report possible cases. Training must be offered during scheduled work times and at no cost to the employee.

Workers required to use PPE must be trained. This training includes when to use PPE; what PPE is necessary; how to properly don (put on), use, and doff (take off) PPE; how to properly dispose of or disinfect, inspect for damage, and maintain PPE; and the limitations of PPE. Applicable standards include the PPE (29 CFR 1910.132), Eye and Face Protection (29 CFR 1910.133), Hand Protection (29 CFR 1910.138), and Respiratory Protection (29 CFR 1910.134) standards. The OSHA website offers a variety of training videos on respiratory protection.

When the potential exists for exposure to human blood, certain body fluids, or other potentially infectious materials, workers must receive training required by the Bloodborne Pathogens (BBP) standard (29 CFR 1910.1030), including information about how to recognize tasks that may involve exposure and the methods, such as engineering controls, work practices, and PPE, to reduce exposure.
