Most efficient use is at base of fire with solid or straight stream.
Water applied in short bursts until fire “darkens down”
Water not applied too long to prevent upsetting of thermal layering.
Adequate ventilation must be provided ahead of fog streams that are used for interior attacks
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?
2. Which of the following pieces of equipment would not normally be carried by advancing hoseline teams?
a. Prying tool b. Single ladder c. Axe d. Portable light
3. 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 protected
b. Word from rescue team that all victims have been rescued
c. All clear signal to enter the structure from telecommunicator
d. Order to advance from fire officer
5. From which side should firefighters approach and attack a fire to prevent fire spread?
a. Leeward b. Unburned c. Windward d. Burning
6. Which of the following stream patterns is most often used to attack a Class A fire when adequate ventilation is provided ahead of the nozzles?
a. Straight stream b. Narrow fog c. Broken stream d. Wide fog
7. 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.
a. Firefighter A b. Firefighter B c. Both A and B d. Neither A nor B
8. What type of stream/tactic should be used to attack an interior fire when adequate ventilation has not been provided?
a. Broken stream from above fire b. Straight stream at base of fire
c. Narrow fog stream on ceiling above fire d. Wide fog stream at center of fire
9. Firefighter A says that if the fire is localized, the stream should be broken for Class A fires by sweeping it up and down to put water on the fire and in the upper levels of the room.
a.Firefighter A b. Firefighter B c. Both A and B d. Neither A nor B
10. When attacking a Class A structural fire, why should water be applied in short bursts and not for too long?
a. To avoid upsetting thermal layering b. To produce sufficient steam for extinguishment
c. To prevent toxic gases from rising d. To avoid exhausting the firefighters
11. What type of attack is not desirable when victims may be trapped or where the spread of fire to uninvolved areas cannot be contained?
a. Direct b. Indirect c. Blanketd. Combination
12. Which of the following is generally not a factor in choosing a hoseline?
a.Tactical requirements c. Speed of deployment
b. Dimensions of entry point d. Potential fire spread
14. Firefighter A says that when a door to the fire area must be opened, firefighters should stay low.
15. What is the maximum length of hose recommended for supplying a master stream device?
a.150 feet c. 75 feet
b. 100 feetd. 50 feet
Select facts about deploying and operating a master stream device. Write the
correct letters on the blanks.
19. Which is not a main use for a master stream?
a. Direct exterior fire attack b. Backing up attacking handlines
c. Direct interior attack d. Protecting exposures
20. Why should master streams be positioned properly when set up?
a. Once in operation, they must be shut down to be moved.
b. Their supply lines may not exceed a specified length.
c. Once the attack has begun, the requisite number of personnel cannot be spared to relocate them.
d. The hydrant must be shut off before the master stream device can be moved.
21. Which of the following is not correct positioning for a master stream directed into a building?
a.Close enough to a window or door so that it can hit the base of the fire
b. In a location that provides maximum coverage of the building face
c. Aimed to enter the structure at an upward angle so that the stream deflects off the ceiling or other overhead objects
d. Aimed to enter the structure at a downward angle so that it can hit the base of the fire
22. What should be the minimum flow of a master stream?
a. 175 gpm b. 250 gpm c. 350 gpm d. 2,000 gpm
23. What is the minimum number of 2½-inch hoselines necessary to supply a master stream?
