High Rise Firefighting (PN 633) Flashcards
(47 cards)
How is a high rise building defined?
‘A building at such a height or position that external firefighting and rescue operations may not be feasible’
What are the 4 headings that hazards at high rise fires can be grouped under?
1) Building height and design
2) Management and use
3) Fire Behaviour
4) Firefighting and Rescue Operations
What do DRM and WRM stand for?
Dry Rising Main and Wet Rising Main
A WRM is required in buildings that are in excess of what height?
60 Metres pre 2006
50 Metres post 2006
The planning requirements for Rising Mains started in the 50’s so buildings from this decade and before may not have these facilities
What 2 basic facilities may be provided?
Firefighting Shaft (protected stairwell) Firefighting Lift
Protected Shafts and Mains ‘May be found’ in buildings exceeding what height?
7.5 Metres
What might the presence of a Sprinkler System indicate?
Larger compartments with potential for higher fire loading
What 5 factors should be considered when establishing the ‘Level of Risk’ at a highrise building?
- Size
- Complexity of Layout
- Contents
- Processes
- Occupiers
What does ORD stand for?
Operational Risk Database
What does the note state should be printed en route from the MDT?
Electronic Premises Information Plate (ePiP).
Note. MkIII Appliances do not have a printer but the rear MDT is detachable.
When siting Appliances during initial attendance what 3 things should be considered?
1) The Siting of oncoming Aerial Appliances
2) Other oncoming special Appliances and Emergency Services
3) Falling Objects
Where should the IC remain?
At ground floor level
When can a ‘High Rise Procedure implemented’ Message be sent? (3)
When:
1) A Risk assessed Bridgehead is in place
2) Access and Egress to Bridgehead is secure
3) The Bridgehead has 2 charged Jets
What should a DRM be able to supply?
1500 lpm
What should a WRM be able to supply?
1500 lpm for 45 minutes
What does HVAC stand for?
Heating Ventilating and Air Conditioning System
Can LFB Personnel switch off sprinkler systems?
Yes, on the instruction of the IC, but it is unlikely
Where is a sprinkler ‘stop valve’ normally located?
Ground Floor
Can firefighters use lifts?
Yes providing that it is a ‘Firefighter Lift’
When using a Firefighting Lift at an Incident where must you get out?
At least 2 floors below
How must a firefighting Lift be controlled?
Operate the fireman’s switch and then designate a firefighter to remain with the lift.
Note. it is often necessary to keep the buttons depressed for operation
Can a firefighter lift be used where the incident location isn’t known?
No, use the stairs!
If the lift is not working what 3 things should the IC consider?
1) Increase Resources for carrying equipment to Bridgehead
2) Use of an Aerial Appliance to transport kit, depending on building design
3) Additional Resources to carry casualties from the Bridgehead
Where should the Bridgehead be established?
2 floors below unless safe to be closer due to building design
