Which of the following potentially cancerous compounds are found in AFFF?
A. Primary carbons
B. Perforated carbons
C. Purified carbons
D. Perfluorinated carbons
Foam prevents potential flammable sources from igniting and extinguishes already burning fuel so
A. reducing fuel temperature
B. suppressing flammable vapors
C. preventing oxygen from contacting the fuel source
D. forming a blanket layer over the combustible liquids
E. reacting with the fuel source to change its chemical composition
Answer (2)
Perfluorinated carbons are the potentially cancerous compounds found in AFFF. Foam functions primarily by forming a blanket over burning liquids and preventing oxygen from fueling the fire. ;
Perfluorinated carbons (D) are the potentially cancerous compounds found in AFFF. Foam functions primarily by forming a blanket layer over combustible liquids, which helps prevent oxygen from contacting the fuel source and suppresses flames. This combination is essential for effective fire extinguishing and safety measures.
