Answer 6

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

Question 7

What is the definition of an adequate fire stream

Answer 7

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

Question 8

In the real world, what is an adequate fire stream

Answer 8

Has enough FLOW and REACHES the seat of the fire

Question 9

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

Answer 9

fuel/flame; Class A Foam

Question 10

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

Answer 10

• 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

Question 11

What are the low pressure combo nozzle characteristics:

Answer 11

• 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

Question 12

List the features of the 1 3/4” nozzle

Answer 12

• 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

Question 13

List 2 1/2” fog nozzle features:

Answer 13

• 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

Question 14

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

Answer 14

• 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)

Question 15

Fog Attack was originally use for:

Answer 15

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

Question 16

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.

Answer 16

occupants; ventilation; steam; Class A; desirability

Question 17

Advantages of a direct fire attack with straight or solid streams

Answer 17

• 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

Question 18

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

Answer 18

quick attack; rear

Question 19

PACT stands for

Answer 19

• Pike Pole, rubbish hook
• Attic ladder
• Chainsaw
• Tarps

Question 20

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

Answer 20

backup lines; protect; egress; prevent fire; behind

Question 21

Discuss the 10 advantages of the current hose beds:

Answer 21

• 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
