Q and A bank Flashcards
According to STP - What are the 3 Golden rules to follow when applying foam?
- Do not begin to apply foam unless you have enough to extinguish the fire or cover the fuel spill
- Point branch away from fire until good finished foam is being produced
- You cannot mix different foam concentrates
According to STP - 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 larger jet reaction than a standard hose
- Slug flow – When the proportion of foam, air and water is wrong. It will cause the finished foam to “shudder” or “pulsate” as it is exiting the branch
- Does not contain enough water for internal attack
According to STP - List 5 actions to take when combatting a natural gas leak with no fire involved.
- Structural PPE and SCBA
- Evacuate all persons from the immediate area
- Remove all sources of ignition
- Respond Gas company
- Only use intrinsically safe equipment
- Dampen ground around the site of the gas release to prevent static electricity
- Keep protection line in place using fog
- If possible, crimp line to stop release of gas
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?
The explosion can occur up to 24 hours after the cylinder is removed from the fire or heat source, if it is not cooled
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 and materials.
Smoke - Colour, density, height of smoke layer/neutral plane, turbulence.
Air Track - how structure ventilation can change air track and influence fire behaviour.
Heat - signs of; blackening (rich conditions) or crazing (high temps) of windows, blistering paint, flame colour (yellow - well ventilated, reddish orange - less oxygen)
Flame colour is also an indicator of heat, yellow flames generally indicate a reasonable air supply. Reddish orange flames indicates less oxygen available.
NEVER RELY ON ONE INDICATOR - READ ALL SIGNS TOGETHER
According to STP - What techniques enable us to control the interior environment during a structure fire?
Gas cooling - long and short pulses.
Controlling ventilation (closing doors to limit ventilation to fire)
According to STP - List 2 common hose laying techniques that can be used by firefighters?
- “S” Lay
- Cleveland Load

As listed in STP - What form populated by firefighters gives the Fire Investigator a summary of firefighter actions at an incident.
SOFA Form (Summary of Ovservations and Firefighter Actions)
STP - Details how a structure fire will burn within one of two burning regimes. List and describe the regimes.
Fuel Controlled: Fire development is dictated by the characteristics (size, material, arrangement) and availability of the fuel in the fire compartment. There is more than enough O2 available for combustion.
Ventilation Controlled: Occurs during a fully developed fire. Fire is pyrolyzing more fuel than can be burnt with available air/O2. Fire growth is limited by the available air/O2 supply.
STP - Identifies the search priority in multi story buildings, list the priorities.
Search priority starts at the fire floor, then floor above and then the top floor. Occupants in these areas are most at risk due to rising heat, smoke and fire gases.
