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

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.

How deep is the trench?
What is the purpose of the trench?
What’s been done so far?
5 signs of impending trench collapse
Parallel cracks
Fretting
Slumping
Bulging walls
Deflection and creaking of shoring
Types of fire alarms
Dry: smoke, heat, flame
Wet: Sprinkler system
What does EWIS stand for and its purpose?
Emergency warning and intercommunication system
Required in buildings over 25 meters, allows occupants to be alerted to an emergency situation via an alter tone, or an emergency message. Two way communication is also possible through WIP phones.
Causes for false alarms
Activities that simulate fire such as grinding
Interference with wiring
Rainwater leak into detector
Improper installation and maintenance
Sprinkler head knocked off
Activation from exhaust emissions
Percentages for foam use
.1 - .3% wet
.4 - .6% medium
.7 - 1% dry
Advantages of CAFS
Light hose
Absorption
Quick knockdown
Extended stream
Pre treatment
More effective than water
Ability to cling to assets
Optimal pressure for foam
700-800kPa
Limitations of CAFS
Affected by wind
Environmental concerns
Time required to flush after use
Higher maintenance
Initial jet reaction
More components/complicated
