Workplace hazard controls for COVID-19
Hazard controls for COVID-19 in workplaces are the application of occupational safety and health methodologies for hazard controls to the prevention of COVID-19. Vaccination is the most effective way to protect against severe illness or death from COVID-19. Multiple layers of controls are recommended, including measures such as remote work and flextime, increased ventilation, personal protective equipment (PPE) and face coverings, social distancing, and enhanced cleaning programs.
Vaccination is the most effective way to protect against severe illness or death from COVID-19. Breakthrough infections happen in only a small proportion of people who are fully vaccinated.[1]
The U.S. Occupational Safety and Health Administration (OSHA) recommends implementing multiple layers of controls, including measures such as remote work and flextime, engineering controls (especially increased ventilation), administrative controls such as vaccination policies, personal protective equipment (PPE), face coverings, social distancing, and enhanced cleaning programs with a focus on high-touch surfaces.[1]
Preliminary evidence suggests that the small number of fully vaccinated people who do become infected can be infectious and can spread the virus to others. The U.S. Centers for Disease Control and Prevention (CDC) recommends that fully vaccinated people can reduce their risk of becoming infected and potentially spreading it to others by:[1]
Along with vaccination, key controls to help protect unvaccinated and other at-risk workers include removing from the workplace all infected people, all people experiencing COVID symptoms, and any people who are not fully vaccinated who have had close contact with someone with COVID-19 and have not tested negative for COVID-19 immediately if symptoms develop and again at least 5 days after the contact (in which case they may return 7 days after contact). Fully vaccinated people who have had close contact should get tested for COVID-19 3–5 days after exposure and be required to wear face coverings for 14 days after their contact unless they test negative for COVID-19.[1]
Additional fundamental controls that protect unvaccinated and other at-risk workers include maintaining ventilation systems, implementing physical distancing, and properly using face coverings, and proper cleaning. Fully vaccinated people in areas of substantial or high transmission should be required to wear face coverings inside as well. Employees may request reasonable accommodations, absent an undue hardship, if they are unable to comply with safety requirements due to a disability.[1]
Randomized controlled trials and simulation studies are needed to determine the most effective types of PPE for preventing the transmission of infectious diseases to healthcare workers. There is low quality evidence that supports making improvements or modifications to personal protective equipment in order to help decrease contamination. Examples of modifications include adding tabs to masks or gloves to ease removal and designing protective gowns so that gloves are removed at the same time. In addition, there is weak evidence that the following PPE approaches or techniques may lead to reduced contamination and improved compliance with PPE protocols: Wearing double gloves, following specific doffing (removal) procedures such as those from the CDC, and providing people with spoken instructions while removing PPE.[2]
Workers' rights[edit]
In the United States, under the General Duty Clause of the Occupational Safety and Health Act of 1970, employers are responsible for providing a safe and healthy workplace free from recognized hazards likely to cause death or serious physical harm, which includes COVID-19.[1] In addition, OSHA's Emergency Temporary Standard applies required measures to most settings where any employee provides healthcare services or healthcare support services.[4] Section 11(c) of the OSH prohibits employers from retaliating against workers for raising concerns about safety and health conditions, and OSHA encourages workers who suffer such retaliation to submit a complaint to OSHA's Whistleblower Protection Program within the legal time limits.[5][6]
On July 15, 2020, Virginia adopted binding safety regulations on COVID-19, the first such regulations in the United States. The regulations includes mandates about control measures and prohibits retaliation against workers for expressing concern about infection risk, and provides for fines of up to US$130,000 for companies found in violation.[7][8] As of July 2020, Oregon adopted a timeline that targets the establishment of COVID-19 regulations for September 1.[9]
