Q.1 What are the 3 golden rules to follow when applying foam?
*Don’t start to apply foam unless you have enough to extinguish the fire or cover fuel spill.
*Point branch away from fire until good finished foam is being produced.
*Don’t mix different foam concentrates.
Q.2 List 3 hazards/considerations when using CAFS at a structure fire.
- CAFS hose lines have a build up of pressure when the branch is closed, this causes a large jet reaction than a standard hose.
- Slug flow when the proportion of foam, air and water is wrong. Finished foam will shudder or pulsate.
- Doesn’t contain enough water for an internal attack.
Question 3.
According to STP - List 5 actions to take when combatting a natural gas leak with no
fire involved.

Only use intrinsically safe equipment.
Dampen ground around the site of the gas release to prevent static electricity.
Question 4.
According to STP - Acetylene is a very volatile gas, exploding cylinders can
penetrate double brick walls or metal freight containers & land 200m away. How
many hours after the cylinder is removed from the fire or heat source, if it is not
cooled, can this explosion occur?
24 hours
Question 5.
According to STP - When reading a fire, we need indicators to base our decisions
on, what are the most important indicators?
B-SAHF
Building: Construction style & materials impact fire behaviour.
Smoke: Colour varies with the combustion process.
Airtrack: Relationship between inlet & outlet openings & the way air flows between these points.
Heat: Blackening and crazing of windows.

Question 21.
STP - Details how a structure fire will burn within one of two burning regimes. List
and describe the regimes.
Fuel controlled:-
Initial phase of fire development the fire grows as a direct function of the fuel itself with little or no influence from the compartment environment.
Fires with more than enough air for combustion are fuel controlled.
Ventilation Controlled:-
Most structure fires will reach a stage where fire development and the Heat Release Rate HRR is now dictated by the availability of oxygen.
This occurs during a fully developed fire when fire is pyrolyzing more fuel than can be burnt with the available oxygen in the compartment.
Fire growth and HRR is limited by the available oxygen supply.
