List the characteristics of a good quality foam blanket
Will not be disrupted by wind, thermal updraft or flame attack
Will reseal itself if the established foam blanket is disturbed
Will flow around objects to gain access to cover areas
All of the above
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.
All of the above are correct.
