SUPPRESS URBAN FIRE Flashcards
(40 cards)
What four (4) 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 Tool
- BA Entry Control Board
- Thermal Imaging Camera (TIC)
Which material presents a danger of exploding in fires involving transformers?
Exploding porcelain
What is the difference between a strategy and tactic? Give an example of each for a structure fire;
Strategy - A strategy is a broad plan, developed in support of the control objective that is used to combat the incident.
Tactic - A tactic indicates how a job will be done.
Example– extinguish fire / Tactic using line of 60/40 with branch
Which is the most suitable extinguishing medium when fighting oil fires?
Application of foam
Name the three (3) basic types of storage tank construction?
- Fixed roof (cone) tank
- Internal floating roof tank
- Floating roof tank
Name the three (3) conditions necessary for static electricity to cause ignition?
- Accumulation of a large charge
- A spark gap
- An ignitable vapour/air mixture
List one of the major fall hazards for firefighters in partially built structures.
Missing or incomplete stairways and floors
What is appropriate extinguishing media for small fires involving radioactive materials?
Small fires should be dealt with using dry chemical, CO2, water spray or foam
What three (3) things should you consider when doing a fire “size up”
- What has occurred and is happening
- How the fire or incident might develop
- Your resources
List three types of defects that will result in completing a Vehicle Fault Report?
- Appliance faults
- Faulty/Damaged Equipment
- Missing Equipment
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?
H - Height of the building
A - Area of the building
U - Used for/as
L - Lines of hose used
E - Exposures/Evacuations
R - Resources – current and required
S - Staging
In addition to PPC, what is required to be worn by firefighters when entering smoke and gases produced by a burning vehicle?
BA
Name the principal method by which most oil refinery process unit fires can be extinguished?
Process unit fires can be extinguished principally by the removal of the fuel
What observations can be made on the way to a structure fire?
- People in the area may have seen who or what started the fire, where the fire started, or they may have started the fire themselves. Where names cannot be obtained, at least a description of the person’s features (height, weight, age, hair colour etc.) should be
noted,as well as clothing - Details of vehicles in or leaving the area are valuable as they may help identify the vehicle and its driver later. Details such as registration numbers, vehicle make/type or distinctive features such as roof racks, panel damage etc. are important
- Whether access gates were open, closed or locked. For example, if they were locked, and access via that gate is restricted to personnel with keys, then this may eliminate a number of suspects
- Fire behaviour such as whether the smoke is from one column, or a strip, or separate spots.
Urban fires may be started by four main means: What are they?
- Accidental – heating, cooking, welding, electrical
- Natural – Lightning or spontaneous combustion
- Deliberate – Multiple fire seats, accelerant found
- Suspicious – All accidental causes ruled out and suspicious indicators located
On receipt of a loaned, repaired, or replaced piece of equipment, the firefighter receiving the item should do what?
On receipt of a loaned, repaired, or replaced piece of equipment, the firefighter receiving the item should check it for any faults and if satisfied that it is operational, place it on the appliance in the designated place
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
Amount of water required is (3m x 4m) X 15 = 180L/min, 1,800L over 10 minutes.
Pool Volume m3 = 5m x 7m x 1.6m = 56m3
Pool Litres capacity = 56m3 X 1000 = 56,000L
Total amount of water available is 56,000L and water required is 1,800L
Which extinguishing media should not be applied to an electrical fire?
Water
Hazards involving clandestine laboratories can be grouped into five broad categories: List four (4) of them.
- Improvised or Temporary Laboratory Facilities
- Fire Hazards
- Hazardous Chemicals
- Production Hazards
What is the main problem you face if the fire gets behind you in structural firefighting?
As it cuts off their line of retreat.
Why is radiant heat a problem at structure fires?
Radiant heat can cause combustibles to ignite tens of metres away from the involved building, so it is important to protect nearby structures from exposures.
What are the levels of incident review conducted by DFES?
- Debrief
- Post Incident Analyses (PIA)
- Major Incident Review (MIR)
List five (5) of the hazards you may face in a structural fire situation.
- Heat
- Smoke and Dust
- Electricity
- Flashover
- Backdraught
Name two unique hazards specific to mobile properties?
- Gas cylinders,
- Small confined areas
