Figure 2-17. Fire Hose Nozzles
Foam liquid must be disposed of in compliance with local, state, and federal regulations.
Rinse any spill thoroughly with water as the foam liquid is slippery. The foam liquid poses no
direct hazard, however it should be disposed of in limited quantities at a time to avoid
nuisance foaming in sewer or waterway
Slowly squeeze fire hose nozzle valve levers (1) (fig. 2-17) one at a time until each hose is cleared. The
fire hose nozzle should discharge gas only for 10 seconds.
