High rise definition |
Contains floors at a height where external ff and rescue ops are not feasible |
|
|
Hazards and OP considerations |
Metabolic heat stress Delays in ff & rescue ops Comms difficulties Fixed installations Antisocial behaviour Layout of building Fire growth and smoke travel: -undivided stairways (act like chimneys) -smoke spread (smoke rises and cools then starts to spread laterally causes more hazards) - Fire spread (maybe quicker due to effects of wind 'coanda effect') |
|
|
Features of high rise buildings |
FF shafts Dry or wet riser A fire lift |
|
|
Modern high rise structures |
FF lobby & shaft FCC (Fire control centre) Atrium Comms system Crossover floors Stairs pressurisation system HVAC - heating, ventilation and air con Fixed installations |

Bridgehead |
At least 2 floors below fire floor Under control of CM and ECO |
|
|
Min Equipment taken to bridgehead via lift |
45mm hose Long line 2 branches Tic Breaking in gear BA ECB Access keys/codes 2 BA sets Floor plans (if available) First aid & ressuss kit |
|
|
Committing crews in high rise |
Staircase - more than one staircase then devote one for fire and rescue and other for evac Initial team - committed with line of hose as soon as resources and water supply ready Support team - committed to support initial team with additional jet Comms - hand head radios and fire telephones Other considerations - undertaking tasks elsewhere before fire extinguished |
|
|
3 sectors with sector commander for greater level of control |
Search sector (search and rescue & ventilation) Fire sector ( main area of ops, floors involved in fire) Lobby sector (area of ops from ground level, including bridgehead) |
