Suppress Urban Fire Flashcards
(40 cards)
What four pieces of equipment should be taken if fire is confirmed or there are signs of a fire in a complex building?
- Initial entry bag
- Forcible entry tools
- BA Entry Control Board
- TIC
What is the difference between a strategy and tactic? Give an example of each for a structure fire.
- A strategy is a broad plan, developed in support of the control objective that is used to combat the incident (e.g. an offensive attack or a primary search)
- A tactic indicates how a job will be done (e.g. deployment of resources at an incident)
Which is the most suitable extinguishing medium when fighting oil fires?
- Wet chemical
What is appropriate extinguishing media for small fires involving radioactive materials?
- Dry chemical, CO2, water spray or foam
What three things should you consider when doing a fire “size up”?
- Flame; height, intensity, spread
- Smoke; colour, volume, ventilation
- Heat; intensity, impact on surroundings
List three types of defects that will result in completing a Vehicle Fault Report? (Answers not limited to the following)
- Appliance fault
- Damaged equipment
- Missing items
There are many methods used to assist the OIC in providing the most appropriate information to the ComCen. One such method is the acronym H.A.U.L.E.R.S.? What does it stand for?
- Height of the building
- Area of the building
- Used for/as
- Lines of hose used
- Exposures/Evacuations
- Resources (current and required)
- Staging
In addition to PPC, what is required to be worn by firefighters when entering smoke and gases produced by a burning vehicle?
- Breathing apparatus
Name the principal method by which most oil refinery process unit fires can be extinguished?
- Removal of fuel
What observations can be made on the way to a structure fire?
- Description of people in the area (may have seen who/what started the fire, where the fire started or if they were involved)
- Details of vehicles in or leaving the area (rego/make/model/distinctive features)
- Access gates being open/closed/locked
- Fire behaviour (one column/strip/separate spots)
Urban fires may be started by five main means: What are they?
- Accidental
- Natural
- Deliberate
- Suspicious
- Undetermined
You are the 1st arriving pump driver at a structure fire incident. On site you notice a swimming pool that you estimate is 5m wide, 7 metres long and approximately 1.6m deep. Is this water source sufficient to extinguish a fire that is 3 m x 4 m in size and has been estimated to require 10 minutes of water application? Show calculations.
- Yes, it’s sufficient. The total amount of water available is 56,000L and only approximately 1,800L of water is required.
- Water supply needed in litres per minute = area of fire (L x W) x 15
- Pool volume m3 = (length x width x depth)
- Pool litres capacity = (volume m3 x 1000)
- Water supply needed = (3m x 4m) x 15 = 180L/min (x10min) = 1,800L
- Pool volume = (5m x 7m x 1.6m) = 56m3
- Pool capacity in litres = (56m3 x 1000) = 56,000L
Hazards involving clandestine laboratories can be grouped into five broad categories. List four of them.
- Improvised/temporary laboratory facilities
- Fire hazards
- Hazardous chemicals
- Production hazards
- Weapons (or other security devices)
What is the main problem you face if the fire gets behind you in structural firefighting?
- Risk of entrapment due to having line of retreat cut off
Why is radiant heat a problem at structure fires?
- Radiant heat can cause combustibles to ignite tens of metres away
What are the levels of incident review conducted by DFES?
- Debrief
- Post Incident Analysis (PIA)
- Major Incident Review (MIR)
List five of the hazards you may face in a structural fire situation.
- Heat
- Smoke
- Electricity
- Flashover
-Backdraught
Name two unique hazards specific to mobile properties.
- Gas cylinders
- Small, confined spaces
- Flammable thin building materials
What is a potential hydrant problem in complex buildings?
- Low water pressure
State the hazard that the firefighters must be aware of, after an escaping gas fire has been extinguished?
- Vapour forming on the extinguishment of an escaping gas fire
List two of the causes of entrapment in urban fires.
- Escape routes blocked by collapse of building/debris
- Escape routes blocked by fire
- Escape routes becoming untenable due to radiant heat/other hazards
- Disorientation combined with failure to make adequate use of guidelines
As per SOP 3.4.8 – Electrical Hazards, briefly describe the two step procedure for persons in contact with electrical wires.
- Do not attempt to aid any casualty unless safe to do so, or until the electrical supply has been isolated
- If possible, isolate the power source using the ‘isolation method’ or alternatively, request the assistance of the energy provider for isolation and/or advice to render the hazard safe
Explain exothermic and endothermic reactions.
- Exothermic: chemical reaction accompanied by the release of heat, causing a rise in temperature in the surrounding area
- Endothermic: chemical reaction where the reactants absorb heat, causing a fall in temperature in the surrounding area
What provides protection from radiation?
- Time
- Distance
- Shielding
