Q

Give the following info for the MKV Pumper:
Pump type -
Rated water capacity -
Rated Foam capacity at 3% -
Rated Foam capacity at 6% -

A

Pump type - Darley 1000 series mid mounted, single stage centrifugal pump w/ additional high pressure 2nd stage

Rated water capacity - 3800 L/m at 1000kpa @ 3m lift

Rated Foam capacity at 3% - 3800 L/m at 1000kpa

Rated Foam capacity at 6% - 2650 L/m at 1000kpa

17
Q

Identify the 5 Friction loss laws

A

DRISL

Friction loss increases directly with the length of the hose

Friction loss increases directly with the decrease in diameter

Friction loss increases directly as the square of the flow rate

Friction loss increases with the roughness of the interior of the hose

Friction loss for all practical purposes, is independent of pressure

18
Q

List the formula for calculating Head pressure

A

P = 10 x Height

19
Q

If 700kpa is required at the branch at the end of two length of 38mm hose running up a 5m incline, what pressure would be required at the pump? Show calculations

A

Branch = 700kpa
Hose 2x38mm = 440 kpa
Height = 50 kpa

1190 kpa at the pump

20
Q

What does RECEO stand for?

A

Rescue
Exposures
Containment
Extinguish
Overhaul

21
Q

Give a brief description of ‘Backdraught’

A

The sudden introduction of oxygen into a compartment full of superheated gases that have been starved of oxygen resulting in a rapid deflagration

22
Q

Give a brief description of flashover

A

The sudden and sustained transition from the ‘developing stage’ to the fully developed stage of the fire within an enclosure

23
Q

List 3 reasons why you would ventilate a structure

A
  1. Increase visibility for firefighters attempting search and rescue
  2. Increase survivability of casualties
  3. Reduces damage to building caused by smoke
24

B) non- encapsulated splash suit w/ BA
C) non-encapsulated splash suit w/ respirator/ P2 mask
D) structural firefighting uniform

26
Q

Define the term ‘primary search’

A

A rapid but thorough search of all areas which can be entered safely. The purpose of this search is to find and remove all occupants safely

27
Q

Define the term ‘secondary search’

A

Occurs once the incident is under control & the fire has been contained. Emphasis is on thoroughness

28
Q

List the four routes of entry for toxic substances

A
  • Inhalation
  • Ingestion
  • Injection
  • Absorption
29
Q

List 5 Advantages of using foam

A
  1. Utilizes less water, resulting in less water damage to property
  2. Reduces chance of re-ignition due to smothering / insulating effects
  3. Effective against class B fires
  4. Lighter than water and therefore useful in buoyant compartments (ships)
  5. Can be used to extinguish fires where firefighters are unable to gain access to
30
Q

List the 3 types of extinguishing methods for a compartment fire

A
  • direct attack
  • indirect attack
  • gas cooling
