From the Document: "You can protect workers by supporting them in maintaining both personal preventive behaviors (socially distancing, wearing cloth masks, washing hands) and environmental interventions. Evaluate your workplace to identify scenarios where workers cannot maintain social distancing of at least 6 feet from each other and/or riders. Use appropriate combinations of controls following the hierarchy of controls to address these situations to limit the spread of the virus that causes COVID-19 [coronavirus disease 2019]. A committee of both workers and management may be most effective at identifying all possible scenarios."
