FF committed to locate and extinguish a fire must have what |
PPE BA MAIN JET TIC |
|
|
What should FF look for outside the building to locate the fire/how do they locate the fire |
Information from eyewitnesses and premises owners Consult the AFA panel Feel for hot doors and walls Characteristic odours can indicate the type of material burning and assist i locating the fire Listen for crackling which can indicate combustion Look all around the building for signs of fire such as smoke, discolouration of windows, use of the TIC and bear in mind fire can be present with no external signs |
|
|
What can firefighters look for WITHIN the building to help locate the fire |
Look for the origins of the smoke Feel for hot doors, walls and floors Use the TIC to look for raised ambient temperatures |
|
|
What dictates the volume of smoke produced |
The nature of the material The amount of oxygen available The amount of time a fire has been alight |
|
|
What is mushrooming |
When convection currents carry smoke vertically upwards from a fire until it meets a ceiling. It the travels laterally until it meets a wall and then fills the room or enclosed space from top to bottom |
|
|
What does smoke indicate |
The presence of unburnt fire gases and usually a lack of oxygen |
|
|
Define weight of attack |
The number of jets, flow settings selected and size of hose used to extinguish a fire |
|
|
What should the IC take into consideration when deciding the weight of attack |
Size and layout Location and access Probable fire loading The size of the fire, fire development, fire growth and fire behaviour |
|
|
What is the preferred weight of attack for all compartment fires |
45mm hose initial attack. Supporting teams should prepare to augment any attack with other 45m hose |
|
|
How long should supporting hose lines be |
At least one length longer than the initial firefighting jet |
|
|
When should a support team be in place before entry is made |
In cases of basement fires |
|
|
What are the two reasons for cutting away |
To investigate a suspected fire To locate and extinguish an inaccessible fire |
|
|
What are the reasons for turning over and damping down |
Small pockets of fire can continue to smoulder under debris. Turning over and damping down ensures all traces of fire are extinguished |
|
|
What methods are used for cutting away |
Use a floor saw on floors and cut as close to the joists as possible On panelling remove beading, use a floor saw to carefully cut Skirting should be removed in complete lengths Ceilings, use a ceiling hook, stand to the side and wear a helmet with visor down to avoid falling debris and protect the face |
|
|
Why are ceilings cut away |
To get a fires in laths or timber joists, to release water standing or collecting above them and to remove portions of ceilings which are dangerous and liable to collapse |
|
|
How should a FF remove plaster |
It should be levered away and then gently hack or saw through the laths. If possible plaster board should be removed in whole sheets |
|
|
Why might a FF need to gain access to an area behind a wall |
To check for fire spread, hot spots or at special services |
