5/20/2021 COV1D-19-Control and Prevention I Occupational Safety and Health Administration <br /> Employers' COVID-19 response plans should utilize the hierarchy of controls, which generally labels and <br /> prioritizes controls in the following order from most to least effective: elimination/substitution, engineering controls, <br /> administrative controls and safe work practices, and PPE. <br /> Efforts to exclude potentially infectious individuals from the workplace are consistent with the aim of eliminating <br /> the hazard. <br /> Engineering controls typically require a physical change to the workplace to isolate workers from a hazard. <br /> Examples of engineering controls that employers may find useful for protecting workers from SARS-CoV-2 include: <br /> ■ Installing plexiglass, stainless steel, or other barriers between workers, such as on assembly lines, or between <br /> workers and customers, such as at points of sale. <br /> ■ Using rope and stanchion systems to keep customerslvisitors from queueing within 6 feet of work areas. <br /> ■ Adjusting ventilation systems to introduce additional outside air and/or increase air exchange to introduce fresh <br /> air. Consult a qualified technician if necessary. <br /> ■ Modifying physical workspaces to increase the distance between employees. <br /> Administrative controls and safe work practices change policies and procedures for how workers perform job <br /> duties to ensure work activities are conducted safely. Examples of administrative controls that employers may find <br /> useful for protecting workers from SARS-CoV-2 include: <br /> ■ Limiting the number of workers assigned to a particular shift in a facility and ensuring workstations are spaced <br /> at least 6 feet apart. <br /> ■ Posting signage, in languages the workers understand, to remind workers, customers, and visitors to maintain <br /> a distance of at least 6 feet between one another and to practice regular hand hygiene. <br /> ■ Providing training and information in languages the workers understand. <br /> • Increasing the frequency of cleaning and disinfection within the work site. <br /> ■ Encouraging or permitting workers to wear cloth face coverings, if appropriate, to help contain potentially <br /> infectious respiratory droplets. <br /> PPE protects workers from hazards when engineering and administrative controls are insufficient on their own. <br /> The types of PPE that workers may need for protection from exposures to SARS-CoV-2 in areas with community <br /> transmission will vary based on work activities, exposure risks, and the results of the employer's hazard <br /> assessment, The Additional Considerations for PPE section provides additional details about PPE selection and <br /> use for all employers whose workers have increased risk of exposure to SARS-CoV-2 during the pandemic. <br /> Because of PPE supply chain concerns during the COVID-19 pandemic, employers should consider whether <br /> operations that require PPE can be delayed either until PPE is not needed (e.g., because the COVID-19 hazard <br /> diminishes) or until PPE supply chains stabilize. Employers should consider accommodations for religious exercise <br /> for those employees who, for instance, have or cannot trim facial hair due to religious belief, or provide reasonable <br /> modifications for persons with disabilities. <br /> Additional Considerations for PPE <br /> Interim guidance for specific types of workers and employers includes recommended PPE ensembles for various <br /> types of activities that workers may perform. In general: <br /> ■ PPE may be needed when engineering and administrative controls are insufficient to protect workers from <br /> exposure to SARS-CoV-2 or other workplace hazards and essential work operations must continue. <br /> ■ PPE should be selected based on the results of an employer's hazard assessment and workers' specific job <br /> duties. <br /> ■ PPE ensembles should reflect the types of exposures identified in an employer's hazard assessment. Most <br /> workers' exposure to SARS-CoV-2 is likely to be through the contact or droplet routes, although some workers, <br /> https:llwww.osha.gov/coronaviruslcontroI-prevention 519 <br />
