High Rise Firefighting 633 Flashcards
What defines high rise
A building containing floors at such height or position that external firefighting or rescue may not be feasible
What are the 3 group hazards of high rise
Building height layout design,
Fire behaviour and development,
Firefighting and rescue operations
What are the challenges with height layout and design
Height effecting personnel equipment water supply Object falling Access Large complex floors Maisonette layout Communication Entanglement Construction
What height of building requires them to make provisions for firefighting
18mtrs
What is the building height that requires a wet riser
Excess of 60mtrs , as of 2006 50mtrs
Firefighting shaft
dry/wet riser
Firefighting lift
How many lpm can a dry riser main deliver
1500LPM
What capacity do wet riser mains have
1500LPM for 45 minutes
What can the IC request if the riser outlets have been vandalised
The FIRE tool roll
What does the FIRE tool roll contain
Riser outlet wheel
Adjustable spanner
Mole grips
Rubber hose
Where should the fire lift remain
The bridge head
Where should the bridgehead be located
2 floors below the fire
What is the minimum rank of the fire sector commander
LFF
What is the FSC role
Establish bridgehead
Commit teams to firefight search and rescue
What is the minimum amount of FF’s the FSC will take to the bridgehead
3 , two in BA and one for BAECO
What equipment should be taken to the bridgehead
2 45mm hose IEC 2 BA sets Long line Breaking in gear BA board TIC FIRE bag Dividing breach 3 hose sleeves 1 DeltaFire quickattack branch Set lift keys FIRE tool roll
As soon as possible the FIRE system should be augmented with
Sufficient hose for two lines to reach the affected area An addition branch Tripod bracket for BA board Access keys codes Floor plans FIB
When can the message “high rise procedure implemented “ be sent
The location of the bridgehead has been risk assessed as appropriate for the incident .
Access and egress to and from the bridgehead is secured and maintained .
The bridgehead is established with two charged jets deployed
Where should the initial charged branch be supplied from
The rising main outlet 1 floor below the fire if available
Where should the second branch be supplied from
Riser main outlet in the fire floor if available and at least 1 length longer
What should the IC identify before operating any heating or ventilation systems
The path the fire heat or smoke will travel

Falling debris
Cordon maintenance
External fire smoke spread
What minimum features are to be considered to donate that a fire lift is safe for use
Primary secondary power supply IP rated wiring Firefighter recall switch at access level Firefighter incar control Firefighter communication systems Floor indicators
What are the advantages of using the DRM
Reduced time taking water to upper levels Reduced amount of hose Reduced frictional loss Less equipment needed Reduced offset of personnel Keeps.stairway clear
