Q

What is an in-line valve that has an internal plastic or steel component shape like a ball and is the values for the discharge port on the pumper? The ball has a hole through its center and all allows water to flow through it when the ball is in the open position no water is allowed to float through it and the clothes position.

A

200-1 and 1000-1

21
Q

What is excellent to for extinguishing stubborn a basement fires

A

Hi expansion foam

22
Q

Difference between class A and class B foams

A

Class B- water is needed to mix the proper foam solution ratio and water is also the vehicle to deliver the product into the fire, a film is formed over the surface of the barren and gasoline to stop in prevent further release flammable vapors( film barrier must remain intact)
Class A - water is the dominant extinguishing Agent not the foam the foam enhances the effectiveness of the water by creating bubbles does increasing the heat absorption service area of the water droplets p. 178

23
Q

Research by NIST has determined that droplets measuring between ‘’’ microns or more efficient and absorbing heat then where the larger heavier droplets

A

250-350

24
Q

an ‘’ agent is one that can render a fuel non-flammable by encapsuling the hydrocarbon molecules. When added to surfactants these agents emulsify grease , petroleum hydrocarbons, paint and other barriers to water penetration

A

emulsifying agents p. 178

25
Q

What class of phones do not contain emulsifying agents

A

class b ( if they did foam blankets would sink to the bottom of the flammable liquids instead of floating on top) p. 178

26
Q

Class, what foams breakdown the surface intention of water, making it more effective and extinguishing fuels

A

ClassA p. 179

27
Q

Class one foams can prep and protect threatened structures in wildland/urban interface fires

A

class A p. 180

28
Q

Company officer who decider to use pre-connected classA foam attack line when it’s known that ventilation may be delayed is making a

A

Wise move( thoroughly wedding the burning fuel the fire triangle is quickly broken) p. 181

29
Q

Primary damage refers to the damage that just caused directly by

A

The fire

30
Q

Secondary damage is damage caused directly by

A

Firefighters efforts

31
Q

What is the complete extinguishment of fire and usually starts after the initial fire is knocked down it involves looking for hidden fires and wall ceilings and void spaces that are still causing primary damage

A

Overhaul

32
Q

What is an advanced method of making class A foam solution

A

CAFS P. 182

33
Q

What are the four basic hose lays for establishing a water supply?

A

Forward LAY
Split lay
Direct to engine
Reversely the most

34
Q

the most advantageous hose lay is the

A

Forward lay from hydrant to fire

35
Q

Which lay helps engine companies comply with the two in two out rule

A

Forward lay p. 183

36
Q

Most rooms in content fires in the incipient or early growth the stage are extinguished with less than how many gallons of water

A

100 gallons of water

37
Q

Water approach is when a supply line is laid from a hydrant to the fire, but the line is left uncharged for another company to hook up to the hydrant in charge of the supply

A

forward lay - dry p. 184

38
Q

What lay is a dry forward, lay by the first arriving engine. The only difference is there is no hydrogen wrap or no water source at the T interception.

A

Split

39
Q

Because the first engine lays forward and the second engine lays reverse it’s called a

A

split Lay

40
Q

Which lay is useful when long, narrow driveway limit axis road without hydrants or dead ends hamper operations at a fire building

A

Split lay

41
Q

Fast water from the tank without supply can be safe and effective procedure only when

A

The fires in the incipient stage or early in the growth stage, it could be extinct for 500 gallons or less
At least two companies are sure arrival p186

42
Q

Advantages of direct to engine no line laid approach are

A
  1. first arriving engine go directly to the fire
  2. Can use pre connects
  3. Knocking down the firewood tank water lowers the temperature inside the structure.
43
Q

Disadvantages of the direct to engine no line laid approach

A
  1. Operation doesn’t work unless companies arrive close together.
  2. Too many companies are required to provide one engine company with the continuous uninterrupted water source.
  3. Little or no margin of safety for interior attack Cruise.
  4. tank Water might run out p. 188-189
44
Q

What lay can sometimes come in handy for grass and small brushfires so it’s good to know about it

A

Reverse lay

45
Q

Most efficient way to lay reverse is using a

A

Trigate
Portable hydrant
Manifold connected to an LDH

46
Q

and LDH provides more volume less friction loss to the

A

Manifold p. 190 -91
