Firefighter A
Firefighter B
Both A & B
Neither A nor B
Which of the following statements about AFFF is correct?
AFFF resists breakdown by dry chemical, making it suitable for use in combination with other agents.
Because of its low viscosity, AFFF will quickly spread across the surface of hydrocarbon fuels to form a vapor-suppressing blanket.
The floating AFFF film is self-sealing when disturbed.
