On November 30, 2020, the California Department of Industrial Relations’ (DIR) Office of Administrative Law approved a new Cal/OSHA Emergency Temporary Standard (ETS) regarding COVID-19. The ETS became effective immediately and applies, with limited exception, to all California employers. Those exempt from ETS compliance are: 1) single-employee employers who do not have contact with others; (2) employees who are working from home; and (3) employees who are already covered under Cal/OSHA Aerosol Transmissible Diseases standards.
