WARNING
ICON 21
Caution must be taken when carrying 5 gal. (19 l) pails of foam agent to top of foam
agent tank. If foam agent is spilled, walking surface can become extremely slippery.
Clean any spilled foam agent before continuing to fill foam agent tank. Failure to
comply may result in injury or death to personnel.
NOTE
Foam cell should be filled halfway up into expansion dome to minimize surface area of
foam agent subject to evaporation. Pour foam agent down center of round tube when
filling tank. This tube goes to bottom of tank and allows foam agent to enter under surface
of foam currently in tank. This is done to reduce aeration of foam agent per NFPA.
7.
Foam agent must be added by pouring through the 4 in. (10 cm) tube; it must be done slowly and carefully to
prevent aeration. If aeration occurs inside tank, stop pouring until foam agent bubbles dissolve. Take care not
to allow water, dirt, debris, or foreign substance to enter tank.
8.
Close expansion dome hatches (4).
9.
Stow right rear access ladder (WP 0013).
