What are the five ways in which foam extinguishes fire?

-Dilutes the surrounding air with water vapour.


-Isolates fuel from the oxygen in the air.


-Forms a speaking blanket over the surface preventing vapour from escaping.


-Intercepts radiant heat from flames.


-Cools the fuel by absorbing heat.

DIFIC

Foam concentrations by ratio...

-Low Expansion, 2:1 - 20:1


-Medium Expansion (non LFB), 20:1 - 200:1


-High Expansion, 200:1 - 2000:1

When foam is produced there are three factors that can be varied:

-Volume of air mixed with solution.


-The size of bubbles.


-Quantity of concentrate added.

A.B.C

The effectiveness of foam depends on the following factors...

-Concentrate in good condition


-Correct mixture of concentrate used


-Good maintenance of equipment


-Correct pump pressure used for the equipment

Good correct good correct

What are the two branches that have foam aspirator attachments?

-Delta Attack 400-S-Pro


-Akron Ground Monitor

What are the four methods of foam application?

-Gentle (from afar to let the foam lose velocity)


-Raindown (aim high to allow foam to drift onto fire)


-Rolling on (aim on the ground to produce a rolling wall toward fire)


-Off wall (onto an object so the foam rolls down the object/wall onto fire)

Seven considerations when using foam?

-Never apply water onto burning liquid.


- If the burning liquid is flowing, apply the foam to the furthest point from the fire.


-Cool surrounding risks with a covering jet.


-Ensure there's enough foam available to apply and maintain a complete seal.


-Preserve foam blanket once application is complete.


-Open branch away from fire until a consistent supply is achieved.


-Dont walk on or drag hose through the foam and disrupt the seal.

NICEPOD

What are the 3 factors determining distance between pumps in a water relay?

1. Flow required.


2. Diameter of hose line between pumps.


3. Contours of the relay route.


How can the output of a water relay be improved?

-Shorten distance between pumps by using more intermediate pumps.


-Increase diameter of the hose used.

What are the two types of water relay?

•Closed circuit- water pumped through hose direct from one pump to the next, using the lpp.


•Open circuit- water is pumped through hose connected to portable dams, reservoirs or the appliance tank before the inlet of the next pump in the relay.

When the base pump is working from open water, what should be done to the spacing between the base and first intermediate pump and why?

Distance between the base and 1st intermediate pump should be reduced.



Base pump is using some energy to lift from open water, so the output pressure to the intermediate pump is reduced.

What are the hazards when using high Expansion foam?

-Claustrophobia


-Disorientation


-Limits audibility


-Mini backdraughts and fire explosions due to pockets of oxygen starved fire and unignited gases


-Severely affected light penetration


-Difficulty in realising spread of fire due to reduction in transmission of heat


-Obscured view of surrounding damage to structure and signs of collapse

Air consumption rates are influenced by a number of factors, such as?

Physical Exertion - The harder the body works, the greater it's demand for oxygen, causing harder breathing.
