In designing a new histo lab, If you contact the industrial flooring 
companies, they have flooring for anti-paraffin, also a company named MLA has 
sticky sheets that catch stuff on shoes, sheets tear off and can be disposed 
of , we also have ordered special clogs for our personnel so they do not 
carry paraffin thru the other labs, they are worn only in histo and are kept 
there. Hope this sheds some light.
