  1. 16 Fire Hose, Nozzles, Streams, and Foam

  2. Nozzles • Give fire streams shape and direction • Classified into groups: • Low-volume • Handline • Master stream • Shut-offs • Quarter-turn valve • Rotary control valve

  3. Smooth-Bore Nozzles (1 of 3) • Consist of shut-off valve and smooth bore tips • Fit handlines and master stream devices

  4. Smooth-Bore Nozzles (2 of 3) • Advantages: • Longer reach than combination fog nozzle • Capable of deeper penetration into burning materials • Operate at lower pressures • Extinguishes fire with less air movement

  5. Smooth-Bore Nozzles (3 of 3) • Disadvantages: • Do not absorb heat as readily as fog streams • Not as effective as fog streams for hydraulic ventilation • Cannot change setting to produce a fog pattern
