Cal/OSHA Aerosol Transmissible Disease Standards
California passed the first two occupational standards in the nation to prevent worker illness from infectious diseases that can be transmitted by inhaling air that contains viruses, bacteria, or other disease organisms: 1) the Aerosol Transmissible Diseases (ATD) standard, which applies to workplaces at high risk for infectious diseases such as hospitals, clinics, emergency medical services, laboratories, prisons, and homeless shelters; and 2) the ATD Standard – Zoonotic, which protects workers from diseases spread to humans by animals.
