[Histonet] FFPE Tissue as a bio-hazard

[Morken, Timothy]

Tanya, in our institution we don't treat intact paraffin blocks as a  biohazard,  but we do collect all trimmings from the microtomes and put in red biohazard bags. The reasoning is that no one outside the lab knows what this stuff is so we err on the side of the safety, or perceived safety, of those downstream in waste cycle.

Subject: [Histonet] FFPE Tissue as a bio-hazard

I am looking for documentation that talks about FFPE tissue as it relates to bio-hazards in the lab.  When and where does tissue change from a bio-hazard to non bio-hazard.    Needing to present to our safety department.  They are ready to put us on lock down ;0/.
Thanks for your help!
