633 High Rise Firefighting Flashcards
What is a High Rise Building
A high rise building, for the purposes of this procedure, may be defined as a building containing
floors at such a height or position that external fire fighting and rescue operations may not be feasible.
What are the 3 Hazard groups involved in High Rise Fires?
(a) Building height, layout and design.
(b) Fire behaviour and development.
(c) Firefighting and rescue operations.
What is the building height required for a dry riser?
18m
What is the building height required for a wet riser?
50m (60m pre 2006)
What may be found in buildings exceeding 75m?
Fire shafts including fire mains
How should High rise details be gathered and recorded?
By conducting 7(2)d Visits and recording on theORD as the premises risk assessment score dictates
How can you increase the PDA for a High Rise?
Submit a request via the special attendance database or out of hours contact the OTD
What should be considered when siting an appliance at a High Rise Incident?
- Aerial appliances
- Access for other agencies
- Falling objects/Debris
Where should the IC be at a high rise incident?
Ground Level unless a forward control centre has been established
What is HVAC?
Heating Ventilation and Air Conditioning Systems
What are the water requirements for Dry and Wet Rising mains?
Dry rising main - 1500 litres per minute (minimum)
Wet rising main - 1500 litres per minute for 45 Minutes Minimum
What is in a F.I.R.E Tool Roll?
Riser Outlet Wheel, adjustable spanner, mole grips and a rubber hose washer - to assist with operation of risers in disrepair.
What floor should a bridgehead be established on?
At least 2 floors below the fire floor.
What is the minimum rank of a fire sector commander?
CM who will be in charge of the bridgehead and committing Crews (early consideration should be given to increasing the rank of the fire sector commander at larger incidents
What is the minimum crew to be sent to establish the bridgehead?
Fire Sector Commander, ECO, Two BA wearers
What is the initial equipment required at the bridge as soon as practically possible?
• Two lengths of 45mm hose with carrying straps • Immediate Emergency Care (IEC) pack • Two BA sets • Long Line • Breaking in Gear • One BA Board • Thermal Imaging Camera) • One F.I.R.E bag containing: − One controlled dividing breeching − Three Hose Identifying Sleeve − One DeltaFire Quickattack branch − One Set of lift access keys − One F.I.R.E tool roll (see Appendix 7)
What additional equipment should be considered at the bridgehead after initial equipment is in place?
- Sufficient hose for two lines to reach the affected area of the building
- An additional branch
- Bracket and tripod for BA board
- Access keys/codes
- Floor plans (if available)
- Forward information board (FIB)
Where can a main jet and a covering jet be run from at a highrise fire?
Main Jet - 1 floor below
Covering jet - fire floor if safe to do so
When implementing high rise procedure what should be sent ASAP?
“High rise procedure implemented” as an informative
What must be in place before High rise procedure can be sent as implemented?
A bridgehead has been established with two charged jets
The bridgehead location has been risk assessed and deemed appropriate regarding the location and scale of the fire
Access and egress from the Bridgehead have been secured and can be maintained
Who should be informed before committing BA crews to the incident?
The Fire sector commander should inform the IC before committing crews
If there are signs of abnormal fire behaviour (flashover/backdraught) what should be established before Firefighting/search and rescue teams are committed?
A covering Jet and BA must be in place
When travelling through door ways, what must crews ensure?
That hose is charged to prevent restricted flow caused by hose being caught under doors
Can Firefighters be deployed above the fire floor without BA?
Yes - If the buildings construction is sound and the area of work is unaffected by smoke or fire - a safety officer will also be deployed to the relevant stair well.
What role can be deployed to help with search and rescue at a Highrise?
A search and rescue coordinator can be nominated
What can be used to help keep track of searched areas at a high rise incident?
An FIB
The High Rise Board
Door marker tags/marking crayon from the FIRE tool bag
What should the IC consider when deciding on evacuation of a high rise?
(a) the effect of firefighting tactics on evacuation (and vice versa),
(b) the resources required to support the evacuation or “Stay put” policy,
(c) where it is safe to do so, using other emergency service personnel to assist with evacuation;
and that widespread evacuation may divert teams from the task(s) they were briefed to undertake which may require additional resources,
(d) the need to establish, if appropriate, separate attack and evacuation stairwells.
When can ventilation take place?
Only on instruction from the IC
What should be considered when planning ventilation of a high rise incident?
(a) any adverse affect on fire development, such as the risk of causing a backdraught or flashover and the effects on personnel and occupants in the hazard zone.
(b) what impact wind may have if doors, windows or emergency exits are opened or should fail
prematurely.
(c) the need to communicate with and possibly withdraw personnel in affected areas or
occupants still in the building.
(d) that sufficient resources are in place to contain the fire if there is a need to breach any built-in or engineered safety systems.
(e) that measures such as covering jets are in place to protect surrounding risks.
At a High rise, what should an external safety officer be aware of?
(a) falling debris,
(b) cordon maintenance for personnel, other emergency services and the public, and
(c) external spread of fire and smoke.
What is the ideal maximum parking distance for a pumping appliance from a Riser Inlet?
18m
What is the recommended minimum load for a firefighting lift?
850kg
What is the difference between a firemans lift and a firefighters lift?
A Firefighters lift is modernised and provides additional fire/water protection and a back up power supply
What is the size of the female inlet on a dry riser?
65mm
What are the recommended pressures of Wet rising mains?
Before 2006 - 4-5 bar
Post 2006 - 8 bar
when are sprinkler systems a requirement in a high rise?
Residential high rise over 30m built after 2006
how many controlled dividing breechings can be used from one rising main?
One
What stop should be used from a High Rise incident?
A full worded stop should always be sent. To ensure all oncoming appliances and officers know that they are no longer required
