1. Foam is ineffective against all of the following fire types EXCEPT
A. Three-dimensional fires
B. Class B fires
C. Pressurized gases
D. Class C fires
E. Class D fires
2. The foam that is best suited to confined space fires is
A. Film forming fluoroprotein (FFFP)
B. Alcohol-resistant aqueous film forming (AR-AFFF)
C. Alcohol-resistant film forming fluoroprotein (AR_FEED)
Answer (2)
Foam is effective against Class B fires, while the best foam suited for confined space fires is Alcohol-resistant aqueous film forming (AR-AFFF). Understanding the correct application of foam types is critical in firefighting. Class B fires are specifically targeted with foam to be effectively extinguished. ;
Foam is effective against Class B fires, which involve flammable liquids. The best suited foam for confined space fires is Alcohol-resistant aqueous film forming (AR-AFFF). This type of foam effectively manages fires involving alcohol and other polar solvents.
