This course will provide attendees with the background behind the use of aqueous film forming foam (AFFF), its association with polyfluoroalkyl substances, or PFAS, and proposals to address AFFF in the codes and standards. The IFC and NFPA 30 have specified AFFF in certain storage arrangements. This seminar will address where the codes and standards are going in relation to AFFF and regulation of PFAS chemicals by the federal government and state governments.
