5.1.1 The Ontario Building Code defines “highrise buildings” as those being seven storeys or more in height or more specifically the floor level of the highest storey of that major occupancy is more than 18 metres above grade.
True or False
Residential highrise buildings are typically compartmented, with non fire-rated walls
separating living units and hallways.
Highrise Firefighting
False
5.1.2 Residential highrise buildings are typically compartmented, with fire-rated walls separating living units and hallways.
Commercial (office) highrise buildings are typically:
A. undivided with only partitions
separating offices and workstation cubicles extending only to a hanging ceiling
and leaving a void space between the ceiling and floor above.
B. divided with fire-rated partitions
separating offices and workstation cubicles extending only to a hanging ceiling
and leaving a void space between the ceiling and floor above.
C. divided with fire-rated partitions
separating offices and workstation cubicles extending only to a fire-rated ceiling
and leaving a void space between the ceiling and floor above.
D. are typically compartmented, with fire-rated walls
separating living units and hallways
A.
5.1.3 Commercial (office) highrise buildings are typically undivided with only partitions separating offices and workstation cubicles extending only to a hanging ceiling and leaving a void space between the ceiling and floor above.
True or False
For highrise buildings, a full size-up is possible and mandatory.
False
5.2.1 For highrise buildings, a full size-up may not be possible due to the complexity and size of the structure. Incoming apparatus with different vantage points will aid in the initial size up and should report any important information to the Incident Commander.
True or False
If the initial size-up confirms the presence of a working fire, the incident shall be upgraded to a second alarm.
True
5.2.3
Why might a full size-up be difficult in a highrise building?
A. Due to number of trucks responding
B. Due to the complexity and size of the structure
C. Due to lack of radio communication
D. Due to civilian interference
B.
5.2.1 For highrise buildings, a full size-up may not be possible due to the complexity and size of the structure. Incoming apparatus with different vantage points will aid in the initial size-up and should report any important information to the Incident Commander.
What action is required if a working fire is confirmed during the initial size-up?
A. An updated CAN report
B. Upgrade to a second alarm
C. Evacuate the building immediately
D. Request mutual aid
B.
5.2.3 If the initial size-up confirms the presence of a working fire, the incident shall be
upgraded to a second alarm.
How should the first arriving pumper position itself?
A. Near the lobby entrance
B. With clear access to the FDC and hydrant
C. On the fire floor
D. At the back or side entrance of the building
B.
5.3.1 Placement of the first arriving apparatus should be geared towards having clear
access to the Fire Department Connection (FDC) and hydrant to become the fireground pumper.
If the first arriving apparatus at a scene is an aerial, what is the Officer’s primary consideration?
A. Determining if the aerial is needed for aerial functions like master stream or balcony access
B. Establishing an incident command post immediately
C. Connecting to a hydrant and beginning fire suppression
D. Waiting for instructions from dispatch
A.
5.3.1 If the first arriving apparatus is an aerial, the Officer will need to quickly determine if the apparatus may be required to function as an aerial (master stream, balcony access etc.) and, if so, apparatus placement should be in the most appropriate location for aerial deployment, or staged for future aerial deployment and the fireground pumper role should be deferred to the next arriving pumper.
If the aerial apparatus is needed for aerial functions, what should the Officer do?
A. Immediately deploy the aerial and bypass other units
B. Park the apparatus as close as possible to the fire
C. Place or stage the aerial for optimal deployment and defer the pumper role to the next arriving pumper
D. Use the aerial for initial fireground pumping operations
C.
5.3.1 If the first arriving apparatus is an aerial, the Officer will need to quickly determine if the apparatus may be required to function as an aerial (master stream, balcony access etc.) and, if so, apparatus placement should be in the most appropriate location for aerial deployment, or staged for future aerial deployment and the fireground pumper role should be deferred to the next
arriving pumper.
What should the Captain of the first arriving apparatus do upon arrival?
A. Connect to the FDC immediately
B. Begin interior water application
C. Begin exterior water application
D. Respond to the annunciator panel to confirm alarm location
D.
5.3.2 The Captain and crew (excluding the driver) should respond to the annunciator panel to confirm type and location of alarm. If more than one floor is indicated, the investigation shall begin at the lowest floor indicated.
True or False
If arriving to investigate
the report of a fire where the building’s alarm system has not activated, the Officer should consider activating a pull station prior to commencing the
investigation if they believe there are credible indications of a working fire.
True
5.3.2
When should the driver/operator pressurize the FDC?
A. Upon arrival
B. Only when directed by the Incident Commander
C. After connecting to the hydrant
D. After confirming a working fire
B.
5.3.3 The driver/operator of the first arriving apparatus should connect the apparatus to the building’s Fire Department Connection (sprinkler/standpipe system), but not pressurize the system until directed by the Incident Commander and connect (but not charge) the apparatus to the appropriate fire hydrant to establish a sustainable water supply with the inline-Relay valve in place.
Typically at a fire alarm activation the apparatus driver/operator would locate the FDC and fire hydrant and be prepared to establish a connection if directed, but not complete the connection unless a working fire is discovered. As soon as it becomes apparent that the incident is a working fire, the apparatus driver/operator shall complete the connection, but the hoses will not be charged until directed by the Incident Commander.
What information should the Captain obtain from building personnel?
A. Building maintenance schedules
B. What the fire panel shows
C. Elevator, fire phone, and master keys
D. HVAC system blueprints
C.
5.3.4 The Captain should obtain information from responsible building personnel or occupants, secure all required keys (elevator, fire phone, master) and if a responsible party from the building is on site, ensure they wait in the lobby for the next arriving Officer.
What must be done if elevators are used for an incident on the fourth floor or above?
A. Secure and ground elevators, and assign Elevator Sector
B. Use available elevators whether or not they are in emergency mode
C. Avoid elevators entirely
D. Send all crew members to the fire floor
A.
5.3.5 If the incident is on the fourth floor or above and elevators will be used, then the crew needs to secure and ground elevators if they are not already on the ground floor. One firefighter will place the elevator (preferably a “firefighter elevator”, if so
equipped) into emergency use and will assume the duties of “Elevator Sector” and shall be equipped with an SCBA and portable radio
What is the purpose of establishing a perimeter around a highrise building?
A. To limit civilian interference
B. To prevent injury from falling debris
C. Required as per the Fire Code
D. To secure apparatus parking
B.
5.2.5
Depending on the findings of the initial size-up, a perimeter or safe zone around the building may need to be established to prevent injury to firefighters and
civilians (falling debris, glass etc.)
Where should the first arriving crew proceed after securing elevators?
A. Directly to the fire floor
B. One floor below the fire floor
C. Two floors below the lowest indicated floor
D. To the lobby

A. CO monitor
B. Thermal imaging camera
C. Highrise hose packs/kit
D. Forcible entry tools
