We’ve put that question before the owner. But like many other NFPA “requirements”, the requirement means nothing to most owners if there is no one to enforce it. Most will not see the value in spending the money no matter what you say to them.

Sent: Wednesday, January 04, 2017 5:10 PM To: [email protected]<mailto:[email protected]> Subject: Shelf life of AR-AFFF foam concentrate [EXTERNAL] The ChemGuard chemist told me, back in the day, that 20 years was their expectation. I seem to recall 3M put a 25-year shelf life on their PFOS (perfluoroctane sulfanate) /PFOA (perfluoroctanoic acid) AFFF, but then their electro-telomerization formulation was halted long-before that expiration date arrived. Surely CH2M-Hill has a test facility where you can put some of this foam through its paces with a turbulent pool fire? We remamber that ease-of-extinguishing tank fires scales exponentially, and not just due to the square of the radius. Scot Deal Excelsior Fire & Risk Engineering gsm: +420 722 141 478
