Aerosol Transmissible Diseases (ATD’s) Biosafety Plan
To comply with Cal-OSHA Title 8, Section 5199
https://www.dir.ca.gov/Title8/5199.html
To the Principal Investigator:
This Biosafety Plan describes the procedures and measures to establish, implement and maintain an
effective program to minimize research laboratory employee exposure to Aerosol Transmitted
Pathogens – Laboratory (ATPs-L) as mandated by California Occupational Safety and Health
Standards board Title 8, section 5199. Consult Appendix D of the standard to determine the specific
pathogens covered under the standard, but note that virtually any human pathogen, including many
pathogens not normally considered likely to infect humans by aerosolization, could be covered under
the standard depending on the potential worker exposure to the pathogen. Some of the agents that are
covered under the ATD standard include all retroviruses, all arboviruses, Salmonella sp., Chlamydia
trachomatis, influenza viruses, Risk Group 2 Mycobacterium sp., and all microbial agents normally
handled at BSL3. Other agents are also covered if used in a manner or quantity that could result in
aerosolization of the agent. Replication defective viral vectors from other than commercial sources
may also be subject to this standard if aerosol exposure to laboratory or animal care staff could occur.
The Standard requires that each laboratory that works with any of the agents specified in Appendix D of
the Standard must develop a biosafety plan which must be reviewed and approved by one of the
individuals identified in (1b), below. The Biosafety Plan must include the required information in
sufficient detail to provide a useful training document for laboratory employees and students. The
information included in Item 4 below should be considered a minimum requirement to be expanded to
reflect actual risks and practices for your work site.
Completion and adoption of this document does not substitute for obtaining a Biological Use
Authorization (BUA) from the Institutional Biosafety Committee (IBC) that authorizes the
possession, storage, transfer, and use of the biohazardous materials noted in this biosafety
plan. Further, completion and annual update of this biosafety plan is a prerequisite for securing
and maintaining IBC approval of your BUA. Where practicable, the information included in this
biosafety plan may duplicate information presented in your Biological Use Authorization, but you are
responsible for training your staff and students in both documents.
