Chapter 13 - Overhaul Operations Flashcards
Recognize that overhaul operations can be a dangerous assignment for firefighters. Realize the importance of an inspection of the building before a concentrated overhaul effort is begun. Understand the principle of controlling personnel during overhaul operations. Define the basic purpose of overhaul. Identify the hazards that may be encountered during overhaul operations. Identify the proceedures to reduce the chances of injury to personnel performing overhaul operations.
When there has been extensive damage to a building during a night fire, it is best to
a. Overhaul using portable lighting; if the entire building cannot be lighted at once, light each room as you proceed from the immediate fire area, outward then upward
b. Overhaul using whatever lighting is available after a short break during which a careful inspection of the building is made and ventilation is provided
c. Overhaul immediately so that the companies can return to service
d. If possible, establish a fire watch and wait until morning to overhaul
d. If possible, establish a fire watch and wait until morning to overhaul.
During the overhaul phase
a. Fire fighters should be allowed to remove those articles of personal protective clothing that are no longer needed as determined by the overhaul inspection
b. Fire fighters should remain in full personal protective clothing but may remove their SCBA
c. Fire fighters should remain in full personal protective clothing, including SCBA
d. The IC should determine the correct level of protective clothing based on atmospheric testing and the overhaul inspection
c. Fire fighters should remain in full personal protective clothing, including SCBA.
Overhaul occurrs during the
nonemergency phase of operation; therefore
a. A more relaxed command system is in order, but the accountability system should remain in effect
b. The formal accountability process can be eliminated and a more relaxed command system established
c. The formal command and accountability systems can be eliminated, but the buddy system must be enforced
d. The ICS and accountability system must remain in effect durint the entire operation
d. The ICS and accountability system must remain in effect durint the entire operation.
When conducting overhaul operations
a. Engine and ladder crews shoud work together in each room - the ladder crew gaining access to concealed spaces and the engine crew in the room with a charged hose line
b. Ladder crews should work in each room checking for fire extension and opening spaces as needed with the engine crew standing by near the perimeter, ready to extinguish any embers or small fires the ladder crew finds
c. Engine crews should remove heavy objects and debris while the ladder crew opens walls and other concealed spaces
d. Engine and ladder crews should be assigned to various areas, each accessing concealed spaces and each equipped with a hose line
Ladder crews should work in each room checking for fire extension and opening spaces as needed with the engine crew standing by near the perimeter, ready to extinguish any embers or small fires the ladder crew finds.
When opening a ceiling to check for fire extension
a. Pull the entire ceiling in any room showing signs of fire entering the ceiling space
b. continue opening the ceiling until there is no sign of fire damage
c. Open small inspection holes in several areas until there is no sign of fire damage
d. Open the ceiling just enough to operate a hose line into the false space, then operate the nozzle on a full fog pattern for at least 5 minutes
b. continue opening the ceiling until there is no sign of fire damage.
Walls constructed of wood lath and plaster
a. Are more susceptable to hidden fire than walls constructed using wooden studs covered with drywall
b. Are more susceptible to hidden fire than walls constructed using metal studs covered with drywall
c. Are more susceptible to hidden fire than walls constructed using metal or wooden studes covered with drywall
d. Are less susceptable to hidden fire than walls constructed using metal or wooden studes covered with drywall
b. Are more susceptible to hidden fire than walls constructed using metal studs covered with drywall.
Which of the following would be an indicator of an intentionally set fire?
a. A point of origin at the bottom of a stairwell
b. Multiple points of origin
c. Holes in floors
d. Any of the above
.d. Any of the above
When covering a roof opening during termination operations:
a. Use an old salvage; cover and nail it to the roof. If two covers are needed, overlap the covers placingthe top cover over the lower cover
b. Use an old salvage cover, slats, and/or boards; wrap the salvage cover over the edges of the slats and/or boards, and then nail through both the cover and boards/slats. If two covers are needed, overlap the covers placing the topcover over the lower cover rolling the cover over the boards/slats
c. Roll a salvage cover over boards and/or slats that are longer than the cover. Roll the cover around the boards so ends of the board protrude beyond the cover and nail the ends of the board (not the cover) to the roof
d. Do not use salvage covers to cover roof openings
c. Roll a salvage cover over boards and/or slats that are longer than the cover. Roll the cover around the boards so ends of the board protrude beyond the cover and nail the ends of the board (not the cover) to the roof.
