The U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) has published “Guidance on Preparing Workplaces for COVID-19” to help companies respond in the event of coronavirus in the workplace.
The guidance was developed in collaboration with the U.S. Department of Health & Human Services (HHS).
The document provides practical guidance for preventing the spread of COVID-19, also known as novel coronavirus, and contains information on safe work practices and appropriate personal protective equipment based on the risk level of exposure.
