NOTE: This procedure is in direct contrast with that required in fire fighting operations
employing mechanical foam agents, such as the “Raindown” technique recommended
when using aqueous film forming foams (AFFF) (FIG 5).
Figure 5 - The AFFF “Raindown” technique
Bank-and-Roll Method:
If an obstruction prevents attacking the fuel from the front using the Plunge
Method and a wall or bank is located at the back of the burning pool of petrochemical, a
straight stream of PYROCAP B-136™ at a 6 percent concentration may be aimed
approximately 6 inches above the fuel level (fig. 6a). A foam will be developed which
will begin to roll back across the fuel surface (fig. 6b). Once control becomes apparent,
the nozzle should be adjusted to a 30 degree setting and the material should be aimed at
the base of the remaining fire as in the Plunge method (fig. 6c).
