Definitions and information on firefighting foams

摘要

I would like to comment on the article about high-expansion foams, High stakes, which featured in the September issue of FP&FEJ. In particular, I focus on the list of foam types given with bullet points on p.46 of the article. First on the list is aqueous film-forming foams (AFFF), followed by alcohol-resistant (AR) concentrates (or should this read foams rather than concentrates?).
