MASTER STREAM

Select facts about suppressing Class A (structural) fires. Write the correct numbers on the blanks.

1. When suppressing Class A fires, what is one of the advantages of coordinating the attack with ventilation?

by advancing hoseline teams? a. Prying tool b. Single ladder c. Axe d. Portable light3. Which of the following is not a step in the nozzle firefighter’s pre-entry

routine?a. Bleed air from the hoseline and check the operation of the nozzle.b. Extinguish any burning material around or near the entry.c. Wet down any exposures around or near the entry.d. Set the proper pattern for attack.4. What should the attack team wait for before entering a burning structure?a. Word from exposure crew that exposures have been protectedb. Word from rescue team that all victims have been rescuedc. All clear signal to enter the structure from telecommunicatord. Order to advance from fire officer

Class A fire when adequate ventilation is provided ahead of the nozzles?a. Straight stream b. Narrow fog c. Broken stream d. Wide fog7. Firefighter A says that to prevent steam from rolling back over the

nozzle, adequate ventilation must be provided ahead of fog streams used for interior attacks.
