PCT 2 Flashcards
What’s inside a booster cabinet?
Connection points for FF’s to connect to internal hydrant system.
Some systems have their own pumps
2x 64mm storz couplings with pressure gauges
Access to mains supply
Block plan
Max test and operating pressures
Entrapment procedure for FF’s
Send Red message to OIC with condition, location, assistance required, cylinder pressure, and personnel with you.
Activate DSU or make tapping noises.
Remain and calm and avoid exertion.
If charged branch available, saturate surroundings
Move to save place near support structure such as a pillar.

What is Overhauling and its components?
Overhaul involves the systematic checking and turning over and wetting down of material to ensure no pockets of fire exists.
Locate hidden fires
Prevents rekindling of fires
Help determine the cause
Prevent unnecessary damage
Describe Salvage operations and its components.
Action taken immediately after the fire to minimise the damage caused by the fire and by the water used to extinguish it.
Three phases:
Preventative
Protective
Recovery
What is ventilation?
The removal and cooling of heat and fire gases with introduction of fresh air.
Considerations for ventilation with a PPV Fan.
Whether fire is completely extinguished
Wind direction
Location and number of inlets/outlets
Rooms to be ventilated
Which rooms are priority
Number of fans required
Impact of exhaust fans
Advantages and Disadvantages of Fog batten.
Advantages -
covers large surface area
Absorbs heat rapidly
Water converted to steam quickly
Minimise damage to property
Maximise water usage
Provides protection for FF’s
Disadvantages-
Short reach
Will not cool hot objects unless directly applied
Steam conversion can burn FF’s in compartment
Impede visibility
What does BSAHF stand for?
Building construction
Smoke
Air track
Heat
Flame
What is flashover and its signs?
A sudden and sustained transition of a growing fire to a fully developed fire.
Ventilation controlled, vented fire
Painful radiant heat
Low turbulent neutral plane
Fingers of flame through smoke
Hot surfaces
Increased rate of pyrolysis
What is back draught and its signs?
If fire gases accumulate to significant proportions and then an admission of air occurs causing sudden deflagration.
Ventilation controlled, non vented fire
Lack of visible flame
Dirty smoke
Smoke pulsating through openings
Air being drawn in
Indications of extreme heat
What is the blow torch effect and its signs?
Created when a vented fire is exposed to high winds from the inlet. Rapidly progressing through the stage of combustion.
Pulsing smoke
Working fire
Ventilation controlled, vented fire
High winds
Process for Evacuating multi story building.
Priority given to fire floor and floor above.
Staging area floor below fire
