Aerosol Transmissible Diseases

The California Occupational Safety and Health Administration (Cal/OSHA) issued the Aerosol Transmissible Diseases Standard, Title 8 Section 5199, in August, 2008, to mitigate occupational exposures to pathogens transmitted via aerosols and droplets. The regulations specify that employers must implement an effective program to minimize exposure of employees to aerosol transmitted diseases (ATD).

Scope of the Regulations with Regard to Laboratory and Field Research

Principal investigators with research involving any of the agents listed in “Appendix D: Aerosol Transmissible Pathogens – Laboratory” of Title 8, Section 5199 must establish, implement and maintain a written biosafety and exposure control plan that meets the requirements of subsection (f). The regulations require precautions for aerosol as well as droplet generating procedures. As such, Appendix D even includes enteric pathogens, e.g., Salmonella spp.

Additionally, § 5199.1 Aerosol Transmissible Diseases - Zoonotic explicitly covers operations involving the capture, sampling, or transportation of wildlife and operations involving samples, cultures, or other materials potentially containing zoonotic aerosol transmissible pathogens.

The ATD Biosafety and Exposure Control Plan template provided below is intended to fulfill the requirements specified by the ATD Standard. The completed plan will describe the program elements needed to minimize occupational exposure to aerosol transmissible pathogens for laboratory and field operations. Principal investigators must fill in the required information in sufficient detail to provide a useful training document for all research personnel. Principal investigators are responsible for training staff and students on the exposure control plan. The same plan may be implemented for multiple biological use authorizations and/or animal care and use protocols. This exposure control plan shall be reviewed and filed with the campus biosafety officer to document compliance with the standard.

For questions, contact the biosafety officer at 805.893.8894.

Field Research

§ 5199.1 Aerosol Transmissible Diseases - Zoonotic explicitly covers operations involving the management, capture, sampling, transportation or disposal of wild birds or other wildlife and operations involving samples, cultures, or other materials potentially containing zoonotic aerosol transmissible pathogens. The campus biosafety officer monitors all approved extra-institutional animal care and use protocols that entail work in UCSB’s California field sites. Principal investigators conducting research that is covered by § 5199.1 will be contacted by the biosafety officer to ensure compliance with the Cal/OSHA ATD Standard.
