Fire behaviour/development
Firefighting/rescue operations
Min building height you might find a FF shaft (including fire mains)
7.5metres
DRM/WRM flow
DRM 1500 LPM
WRM 1500 LPM 45 min flow 4-5 bar

Competent Firefighter
Describe sectors in a high rise fire
FIRE SECTOR- fire floor
SEARCH SECTOR- above fire floor
LOBBY SECTOR- all floors below the bridgehead

4
LFF
ECO
2 BA

Additional equipment ASAP Sufficient hose for 2 lines to reach affected area Additional branch Bracket/tripod Access codes/keys Floor plans FIB
When can the message HIGH RISE PROCEDURE IMPLEMENTED
Location of Bridgehead risk assessed
Access and egress secured
Bridgehead established with 2 charged jets
What consideration might IC make at a larger incident when BA heavy for S&R
Nominate a Search Coordinator
Whilst firefighting there will be fore doors open. What might the IC have to do if there’s a change in wind flow due to ventilation/HVAC
