A

Go to the floor below to examine the layout.

52
Q

How much hose should nozzle men have at the door to the fire area?

A

One 50 ft length is enough for most homes and apartments.

53
Q

How should you stretch the lead for fires above the ground floor?

A

54
Q

The nozzle team should stretch dry to a safe area or ___________ before calling to have the line charged.

57
Q

It is important to get low in a working fire because there could be a difference of more than _______ in the zone between 2 and 3 feet off the floor.

A

200 deg F

58
Q

What step can be taken while waiting for water at the door?

A

Look below the smoke to get the layout of the area.

59
Q

When the line is charged, what should you do before entering the fire area?

A

Bleed off air and check the pattern.

60
Q

A good rule of thumb is to open up the nozzle only when you see flames. What is an exception to this rule?

A

When extreme heat and no visible fire is preventing your advance.

61
Q

What method of attack is most often used in the free burning stage?

A

Combination attack

62
Q

Combination attack

A

Sweep the ceiling with a straight stream, side-to-side or clockwise motion for 5 to 10 seconds then drop the stream to sweep all of the burning material in the room.

63
Q

In the free burning stage, ceiling temperatures in a fire room will reach________, while those at the floor are in the range of________.

A

1200-1500 deg F

125-150 deg F

64
Q

What are three advantages of the combination attack?

A
  1. By hitting the ceiling first, you cool the fire gases nearest the line without creating a lot of steam.
  2. By shutting down the line when no further fire is visible, you won’t disturb the thermal balance too severely.
  3. Combination attack puts the firefighters inside the structure near the seat of the fire and in the best position to to save lives.
65
Q

What are 2 disadvantages of the combination attack?

A
  1. Puts members in a hostile environment.

2. Requires live-fire training to develop proficiency.

66
Q

Smoldering stage

A

Fire has burned up nearly all the fuel and is approaching self extinguishment, OR the fire has consumed all the oxygen and has reached 1,000 deg F throughout the room, and there is a high potential for backdraft.

67
Q

What is the first tactic to consider if you suspect that a backdraft is possible?

A

Vent the highest portion of the affected area.

68
Q

When fighting fire in a commercial building at night and roof ventilation is not possible, consider_____________.

A

Using the indirect attack.

69
Q

Who pioneered the indirect attack?

A

Chief Lloyd Layman of the USCG

70
Q

How much does a gallon of water expand when fully vaporized?

A

1,500-2,000 gallons

71
Q

4 Requirements of an indirect attack?

A
  1. No occupants
  2. Limited ventilation
  3. High heat
  4. Limited size of potential fire area
72
Q

How do you execute an indirect attack

A
  1. Create a very small opening in a window or door.
  2. Direct a 30 degree fog pattern through the opening.
  3. Keep the stream open until the volume of steam expelled around the nozzle begins to diminish substantially.
73
Q

You are at a fire in a strip mall when backdraft conditions are suspected and neither roof ventilation nor indirect attack are possible, how should you proceed?

A
  1. All personnel are moved to safe positions or shielded.
  2. One firefighter stands to the side of a window and swings a 6’ or longer hook at the window.
  3. Simultaneously, the nozzleman shall direct a 2-1/2” stream through the opening.
74
Q

Can a backdraft occur at a fire that is free-burning?

A

Yes, in adjacent areas that have not yet been vented.

75
Q

5 advantages of indirect attack?

A
  1. Reduced exposure to backdraft.
  2. Can extinguish fire in high heat areas that cannot be entered.
  3. Allows a smaller crew to put out the fire than could advance a 2-1/2” hose for extinguishment.
  4. Uses less water.
  5. Water damage may be less.
76
Q

5 disadvantages of the indirect attack?

A
  1. Building must be unoccupied.
  2. Requires limited ventilation.
  3. Discharge of less than critical volume may push fire ahead of the steam.
  4. It isn’t possible to view the interior layout until the fire is under control.
  5. Can increase water damage if used in an inappropriate situation.
77
Q

What are the three possible actions at a structure fire?

A
  1. Offensive attack,
  2. Defensive attack.
  3. Take no action.
78
Q

Can you use a water curtain for exposure protection?

A

No, the radiant heat will pass through. Instead, coat the exposed surface with water.

79
Q

At a fire in a warehouse storing pesticides or poison, should an offensive or defensive attack be done?

A

No action should be taken due to the potential for runoff causing greater problems.

80
Q

When human life is at stake, _____________.

A

an offensive (interior) attack is mandatory.

81
Q

Don’t use an outside stream in ____________.

A

An occupied building.

82
Q

Get the first hoseline in operation to cover the worst case before _______________.

A

stretching additional lines.

83
Q

When an attack is stalled, ____________________.

A

Increase ventilation, water flow, or both.

84
Q

Only these two things should prevent a hoseline’s advance:

A
  1. Heat

2. Flame

85
Q

Rule of thumb for backup line?

A

It must be at least as large as the original line.

86
Q

When an effective offensive attack isn’t possible or hasn’t succeeded within 20 minutes __________.
