The only way to know for sure what the risks are for your specific operation is to do the risk assessment. You said “spraying pobio [potentially biohazardous] materials as a testing/mfg process” plus you mentioned “possible aerosolization of viral particles (Hepatitis, HIV, etc)” … seems (to me, anyway) to introduce a risk that’s definitely > 0.  If employees aren’t using at least N95s, then your facility must have some exceptionally good engineering in place.  


If your facility were operating in California, then the information you shared would trigger writing a facility-specific Aerosolized Transmissible Disease (ATD) plan.  Not that you need to do that of course, because your facility is located in Illinois.  I only mention it because you asked, and it might be interesting to the list how some jurisdictions might weigh in on this subject.     


From appendix D of =A75199. Aerosol Transmissible Diseases,


Retroviruses, including Human and Simian Immunodeficiency viruses (HIV and SIV) (activities with high potential for aerosol or droplet production, large quantities or high concentrations)




Hepatitis B, C, and D viruses (activities with high potential for droplet or aerosol generation, large quantities or high concentrations of infectious materials)


The Cal OSHA ATD rules are the respiratory disease version of the BBP rules.  And the persistent rumor has it that the ATD rules will spread to the rest of the country like H1N1.

Kathy - I think you need to give the list a bit of insight into "POBIO" - I was assuming you mean the Mitsubishi term for the resins/chemicals/materials harvested from "biological sources" (which is a far cry from what most of us usually think of as "Potentially Biohazardous" - still - does require some consideration of best practices for recombinant DNA/infectious agents research...

Hi Patty,


I'm trying to determine whether spraying pobio materials as a testing/mfg process would present any significant health risk or require any specific containment device due to possible aerosolization of viral particles (Hepatitis, HIV, etc).

Hi Kathy,  what specifically are you looking for?
