Control and Prevention
Measures for protecting workers from exposure to, and infection with, SARS-CoV-2, the virus that causes Coronavirus Disease 2019 (COVID-19), depend on the type of work being performed and exposure risk, including potential for interaction with people with suspected or confirmed COVID-19 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 SARS-CoV-2 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 SARS-CoV-2. The general guidance below applies to all U.S. workers and employers. Depending on where their operations fall in OSHA's exposure risk pyramid (Spanish), workers and employers should also consult additional, specific guidance for those at increased risk of exposure in the course of their job duties broken down by exposure risk level.

Regardless of specific exposure risks, following good hand hygiene practices can help workers stay healthy year round.
General Guidance for All 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.
Practice good respiratory etiquette, including covering coughs and sneezes.
Avoid close contact with people who are sick.
Stay home if sick.
Recognize personal risk factors. According to U.S. Centers for Disease Control and Prevention (CDC), certain people, including older adults and those with underlying conditions such as heart or lung disease or diabetes, are at higher risk for developing more serious complications from COVID-19.
OSHA and the U.S. Department of Health and Human Services (HHS) provide joint guidance for all employers on preparing workplaces for COVID-19 (Spanish).
The CDC has also developed interim guidance for businesses and employers to plan for and respond to COVID-19. The interim guidance is intended to help prevent workplace exposure to acute respiratory illnesses, including COVID-19. The guidance also addresses considerations that may help employers as community transmission of COVID-19 evolves. The guidance is intended for non-healthcare settings; healthcare workers and employers should consult guidance specific to them, including the information below and on the CDC coronavirus webpage.
Interim Guidance for Workers and Employers of Workers at Lower Risk of Exposure
For most types of workers, the risk of infection with SARS-CoV-2 is similar to that of the general American public. Workers whose jobs do not require contact with people known to be, or suspected of being, infected with SARS-CoV-2, nor frequent close contact with (i.e., within 6 feet of) the general public are at lower risk of occupational exposure.

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.
As the Hazard Recognition page explains, workers’ job duties affect their level of occupational risk, and such risk may change as workers take on different tasks within their positions.
Employers and workers in operations where there is no specific exposure hazard should remain aware of the evolving community transmission. Changes in community transmission may warrant additional precautions in some workplaces or for some workers not currently highlighted in this guidance.
Employers should monitor public health communications about COVID-19 recommendations, ensure that workers have access to that information, and collaborate with workers to designate effective means of communicating important COVID-19 information. Frequently check the OSHA and CDC COVID-19 websites for updates.
Interim Guidance for Workers and Employers of Workers at Increased Risk of Occupational Exposure
Certain workers are likely to perform job duties that involve medium, high, or very high occupational exposure risks. Many critical sectors depend on these workers to continue their operations. Examples of workers in these exposure risk groups include those in:
These workers and their employers should remain aware of the evolving community transmission risk.
As discussed on the Hazard Recognition page explains, workers’ job duties affect their level of occupational risk. 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
