No, we do not have such a test facility. We don’t do that kind of work.

Sent: Wednesday, January 04, 2017 5:10 PM To: [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
