|
|
What determines the distance between the pumpemin a water relay? |
Size of diameter of hose inbetween pumps The flow required Contours of relay route |
|
|
Pressure and flow setting of foam branch ? |
6 bar @ 400lpm |
|
|
What contribute to the effectiveness of foam |
Concentrate in good condition Good condition/ maintenance of equipment Correct pressure of pump used for equipment Correct mixture of foam concentrate uses |
|

2nd set tally - where it goes and what to do with it |
Put at in the bottom slots of ECB ( above emergency ba teams tallys) Write second set on tally Bracket the tallys on ECB and write emergency BA Team |
|
|
What are the signs if a fire outside a building DUFS |
D - discolorations of windows/ blistering of paintwork ( indicatesnheat presence in compartment) U - Use TIC to look for unusually high temperatures on the building boundary ( specifically on doors, windows and openings) F - Fire can also be present without showing any external signs in this case further information should be gathered to help locate the fire S - smoke emerging from building ( confirms fire but isn't a reliable indication of fire location or its size) |
|
|
Functions of ICP and how to identify it |
Identify it by its blue flashing lights Its function is:
To provide comms link between lfb control and IC Remains focal point for incident |
|
|
Definitions of incident command |
A system to promote safe and effective resolutions of events through the deliberate allocation and direction of resources |
|
|
Signs and and actions of fire gas ignition |
Signs:
Fire burning for some time Accumulation of fire gasses outside the fire compartment
Actions:
Communicate it to other reviews, eco, sc or ic Consider withdrawing Ventilate gasses from adjacent comp Cool and dilate fire gasses that have leaked from fire compartment |
|
|
Types of pulses |
Long pulse Short pulse |
|
|
Purpose of long pulse |
Extinguish flaming combustion in gas layer Allow ff to advance through compartment |
|
|
What are the fire stages |
Developing g fire stage Flash over stage Fully developed fire stage Decay stage |
|
|
Purpose of short pulse |
Provide safe zone by cooling gasses in immediate proximity/vicinity of firefighting team |
|
|
Fire switches on fire lift |
Deactivate the landing calling button Automatically returns lift tomground level Enables ff only to control the lift (once at ground level) using lift car buttons |
|
|
Equipment taken to bridge head |
TIC 2 x Branches 2 x 45mm hose Long line IEC Breaking in gear 1 x ECB |
|
|
Location of bridgehead |
2 floors below fire floor and one above the lobby sector |
|
|
Operating tempmof the TIC |
-35° to 450°c |
|
|
Spot temp of TIC |
(-)40° to 1000°c |
|
|
What is a heat Barrier |
This is when the smoke and fire gases are hotter than the surrounding air, it therefore rises making the entrance of stairs and entrance of basement like a chimney or flute |
|
|
What is offensive ventillations |
This is when the ventiallations directly affects the fire itself, limiting fire spread and improving conditions in the fire compartment |
|
|
Advantages of tactical vemtillations AIRSII |
A - assist with escape of occupants and FF by restricting speed of smoke I - improve condtions for FF and trapped ocupants R - reduce fire spread and damage to property by controlling movement of hot smoke and gases S - speed up rescue operation and fire attack by reducing neat and smoke I - improve visibility I - increase safety of FF by reducing risk of flash over, backdraught, fire gas explosion |
|
|
Define special services |
Any occurance dealt with by the LFB, which doesn't involve a fire or suspicion of fire |
|
|
What setting should be in a branch for gas cooling |
Min of 230lpm Short rapid burst |
|
|
Actions taken for sprinkler main stop valve |
Ensure that valve isn't c.osed ( except on specifics orders from ic)On the order of the IC open the valve if its found closed ic) On the order of the IC open the valve if its if its found closed |
|
|
Where can a direct fire extinguishing method be applied to? Its branch setting and effects |
Fully ventilated fire Fire in early stages ( before neutral plane has developed) Fire gasses are under control From outside if nincauslties involved Branch Narrow spray or solid jet Effects Exntiguish fire Potential for excessive water damaged Air can be entrained into the comp and fire (intensifying reaction ) With limited ventalation where an over pressure has developed it has potential to lower neutral plane and worsen conditions for ff and casualties |
|
|
Locating a fire within a building |
Look fir origins of the smoke and for the signs of heat damage eg blistering of paintwork Feel for hormdoors, walls as they will be reliable guides of presence of fire ( rise in ambient temp = getting closer to fire) Use of tic to look for raised ambient temo hot surfaces and doorways |
|
|
Info for locating fire outside building |
Gathers all information from eye witnesses and the premises owner Consult afa panel as will tell you what sprinkler head was activated Feel for hot doors Character it odours could indicate type of material burning Listen for crackling - indicates combustion |
