8.1 Commercial/Industrial Fires Flashcards
Why is caution advised when significant fires exist in large commercial structures with steel-frame construction?
a. To ensure proper ventilation
b. To protect downwind exposures
c. Due to the potential compromise of the roof system
d. To prevent the spread of superheated gases
C
What is the significance of conducting a proper size-up in large commercial structures?
a. To locate the fire
b. To estimate the size of the structure
c. To identify potential exhaust openings
d. To assess the compromise of the roof system
A
Why should entry be made as close as possible to the fire location in large commercial structures?
a. To minimize SCBA air consumption
b. To limit travel and working time
c. To facilitate water application
d. To avoid potential exhaust openings
B
What is the primary consideration regarding the flow path in large commercial structures?
a. Minimize movement of superheated gases
b. Increase the movement of superheated gases
c. Direct streams onto exposed structural steel
d. Take out glass indiscriminately
A
What is the recommended method for cooling high heat conditions at the roof level in a Type II building?
a. Use small diameter hose streams
b. Direct large diameter hose streams onto exposed structural steel
c. Utilize aerial devices angled downward
d. Indiscriminately take out glass for ventilation
B
How should water application be approached in large commercial structures, especially for cooling steel roof joists?
a. Utilize multiple hoselines
b. Connect to the sprinkler system only
c. Use straight streams for their penetration characteristics
d. Avoid cooling exposed steel elements
A
What should be considered when extinguishing fires in large commercial structures compared to high-rise or residential structures?
a. Use of standpipe connections
b. Utilization of handlines from a pumper
c. Both a and b
d. Neither a nor b
C
Why is the size of a fire in large commercial structures potentially deceiving?
a. Due to the effectiveness of aerial devices
b. Because of the size of the structure
c. Lack of sprinkler systems
d. Rapid fire spread in open spaces
B
In heavily involved structures, what method of fire attack should be considered for effectiveness?
a. Standpipe connections
b. Residential handlines
c. Aerial devices with master streams (storefront attack)
d. Sprinkler system connection
C
What type of hoseline is recommended for protection of fire personnel during rescue operations in large commercial structures?
a. 65mm hoseline
b. 45mm hoseline
c. Small diameter hose streams
d. Blitzfire appliance
B
What is the first action that the First Arriving Apparatus should take upon arrival at the scene?
a. Ladder the building
b. Establish command and transmit initial radio report
c. Begin fire attack operations immediately
d. Coordinate tactical ventilation
B
What consideration should the Captain of the First Arriving Apparatus keep in mind regarding the water supply?
a. Utilize the onboard water tank before catching a hydrant
b. Catch a hydrant only if there is an obvious working fire
c. Transmit a follow-up radio report before water supply planning
d. Liaise with on-scene building personnel for water supply details
B
How should the First Arriving Apparatus identify the location of the fire if building personnel are not on site?
a. Use thermal imaging cameras
b. Check the annunciator panel if available
c. Initiate tactical ventilation
d. Transmit a primary search report
B
When should the First Arriving Apparatus conduct a primary search and evacuate occupants?
a. Immediately upon arrival
b. After establishing command
c. Upon identifying the fire location
d. After transmitting the initial Incident Action Plan
C
What is the primary responsibility of the First Arriving Aerial?
a. Stretch a 65mm hoseline
b. Coordinate tactical ventilation
c. Ladder the building according to incident needs
d. Establish command and transmit initial radio report
