Aerosol Transmissible Disease Prevention

The Cal/OSHA Aerosol Transmissible Diseases (ATD) standard was adopted in 2009 to protect employees who are under added risk of contracting certain airborne diseases due to the work they perform. The requirements for employers under this standard are found in Title 8 of the California Code of Regulations, section 5199.

This course will review the requirements of this rule and will allow for you to ask questions regarding which employers are “full standard employers” vs “referring employers”. We will review issues of compliance related to effective screening procedures, isolation precautions, respiratory protection and more. 

Current regulation in California is requiring that employers maintain a COVID-19 Prevention Program in writing. This is in addition to the requirement for some employers to comply with the Aerosol Transmissible Disease Prevention standard (ATD standard).
