 ANSULITE® 1% AFFF (Aqueous Film-Forming Foam) Concentrate is formulated
from specialty fluorochemical and hydrocarbon surfactants along with
solvents. It is transported and stored as a concentrate to provide ease
of use and considerable savings in weight and volume. It is intended for
use as a 1% proportioned solution in fresh, salt or hard water. It may
also be used and stored as a 1% premixed solution in fresh or potable
water only. The correct proportioning or mixture ratio is 1 part
concentrate to 99 parts of water.
Three fire extinguishment mechanisms
are in effect when using
ANSULITE 1% AFFF Concentrate. First, an aqueous
film is formed which works to help prevent the release of fuel vapor.
Second, the foam blanket from which the film-forming liquid drains
effectively excludes oxygen from the fuel surface. Third, the water
content of the foam provides a cooling effect.
