seat of the fire; ventilation; rescue

1
Q

The fundamental role of a paid professional fire department is to _____ ____ and reduce _____ ____

A

save lives; property loss

2
Q

T/F - Many fire officers conclude that tactics and water flow can only be determined by experience.

A

False

3
Q

There are 14 points the Company Officer should be thinking about enroute to or after arriving on scene:

A
Location of the fire;
Fire Extension;
Life Hazard;
Time of Day;
Weather;
Construction Type;
Building Height;
Area of Fire Involvement (L X W, as relates to fire flow estimates)
Occupancy;
Access;
Internal Systems;
Water Supply;
Apparatus;
Personnel
4
Q

If the first-in officer is faced with a ‘confirmed’ rescue situation, the officer will:

A
  • Announce ‘Rescue Mode’
  • Perform a rapid size-up and risk assessment
  • Initiate interior fire attack and rescue, if possible
5
Q

Rescue requires _______ ______; a removal implies _______ the occupants ______ ____ ________ is addressed.

A

immediate actions; assisting; after fire suppression

6
Q

What is the basic Engine Company job description:

A

To quickly provide a sustained, adequate fire stream where it is needed.

7
Q

What is the definition of an adequate fire stream

A

90% of its volume in a 15” diameter and 75%of its volume in a 10” diameter and stiff enough to attain height or distance in a fresh breeze with no wind blowing, enters a window with enough force to splatter the ceiling

8
Q

In the real world, what is an adequate fire stream

A

Has enough FLOW and REACHES the seat of the fire

9
Q

The seat of the fire is also known as the _____/_____ interface, and becomes critical during fire suppression using _____ __ foam.

A

fuel/flame; Class A Foam

10
Q

To improve our capabilities, the BFD has purchased equipment and adopted procedures to ensure our companies have the ability to succeed:

A
  • Specifically develop adequate fire streams when and where we need them, we use low pressure nozzles and bulk beds.
  • Equipment/Evolutions are designed for deployment by a 3-person engine company
11
Q

What are the low pressure combo nozzle characteristics:

A
  • Single gallonage, constant flow nozzle providing adequate flows at less than 100 psi, creating a more maneuverable line
  • Developed by FDs
  • Larger droplets; less misting
  • More economical
12
Q

List the features of the 1 3/4” nozzle

A
  • Combination breakaway tip
  • High Flow control valve
  • Fog tip flows 150 gpm at 75 psi
  • Remove fog tip, converts to 15/16” solid stream flowing 180 gpm at 50 psi
  • Carried on all 1 3/4” hose beds / bundles
13
Q

List 2 1/2” fog nozzle features:

A
  • 2 1/2” x 2 1/2”control valve
  • 2 1/2” to 1 1/2” reducer (no breakaway)
  • Combo tip flows 250 gpm at 50 psi
  • Transverse and skid loads
14
Q

List the features of the 2 1/2” solid stream nozzle:

A
  • 2 1/2” by 2 1/2” control valve
  • Stream shaper
  • 2 1/2” by 1 1/4” solid tip
  • Carried on all reverse beds (rear 2 1/2” bulk beds)
15
Q

Fog Attack was originally use for:

A
  • Extinguishing fires in unoccupied, unventilated bldgs
  • In the pre-SCBA era
  • For shipboard fires
16
Q

In the era since fog attack was developed, FFs have been recognized as people, and therefore may be considered as _________ of a building. In addition, aggressive _______ has counteracted the effects of ______ in this type of attack. The introduction of _____ __ foam and extinguishing agents has further diminished the ______ of a fog combination attack.

A

occupants; ventilation; steam; Class A; desirability

17
Q

Advantages of a direct fire attack with straight or solid streams

A
  • Better visibility, better work environment
  • Bigger droplet size allows more water to be delivered
  • More water on fuel/flame interface (seat of fire)
  • Less steam, less steam burns to FFs
  • Less pushing of fire into uninvolved areas of structure
  • Quicker and more definite knockdown
18
Q

Hose design is not geared toward a ____ _____, off the ____ of the apparatus.

A

quick attack; rear

19
Q

PACT stands for

A
  • Pike Pole, rubbish hook
  • Attic ladder
  • Chainsaw
  • Tarps
20
Q

Fire attack teams should have staffed ______ ____ in place to _____ the _____ of the attack teams and ______ ____ from getting _____ them.

A

backup lines; protect; egress; prevent fire; behind

21
Q

Discuss the 10 advantages of the current hose beds:

A
  • Designed for easy deployment of 3-member crew
  • Multi-Story and large area bldgs require hose stretches longer than 150’ preconnects
  • Bulk beds meet the need for extended stretches with typical staffing levels
  • Focus of getting the first line into operation. Stats show that fire is usually extinguished, or its extension stopped, with the first line laid
  • Speed is critical
  • Operations centralized to the rear of the engine, keeping the pump panel work area free of obstructions
  • Engine can be spotted where it’s more tactically correct to do so, vs spotting close for preconnect
  • Engine can be spotted on the hydrant when practical to do so
  • Quicker deployment if initial attack line
  • Quicker overhauling of supply line
