Q

The stream must be directed

Onto the surface of the exposure so that the water washes down its walls. The water absorbs the heat that way, and keeps it from igniting. p. 395

Q

If the exposed building has a stand Pipe system, it should be

A

Charged

26
Q

Structures of the material the fire must be covered beginning first on

A

Leeward side or downwind side

27
Q

The combination of convicted and reading he makes the Leeward side

A

Most vulnerable

28
Q

When exposures are close to the building, the most vulnerable areas are

A

Parts of the exposed building just above p. 396

29
Q

Streams should be directed onto the exposure at a level of ‘’’

A

Somewhat above that of the fire

30
Q

Sometimes a Handline hose line is the only way to protect an exposure, but ‘’’’ provide safer and more effective streams for most situations

A

Streams streams p. 397

31
Q

Streams developed by ‘’’ nozzles hold together better and therefore penetrate winds better than spray nozzle streams

A

Smooth, bore nozzles

32
Q

Combination fog nozzle sway straight stream where strong winds are not a factor are probably the better choice for

A

Exposure protection

33
Q

Positioning of exposure, lines is important exposure lines must be placed where

A

They will cover the maximum amount of exposure area

34
Q

The’’ is that maximize the effectiveness of that stream at the same time provides firefighter protection from rating heat and keeps them out of the cop zone

A

Ideal position p.400

35
Q

Why is exposure the second strategic objective andRECEO/VS

A

Inadequate stopping meant that there weren’t enough firefighters to get ahead of the fire and concealed spaces P. 402

36
Q

If there is any possibility of fire and a horizontal or vertical space or shaft that space must be

A

Opened and inspected visually

37
Q

Fires and concealed spaces are the exact condition for which which nozzles were designed

A

Piercing / round nozzles p. 403

38
Q

Many structures contain concealed, vertical shafts that house, utilities, such as

A

Water
Gas
Sewer systems vent pipes
Electrical lines

39
Q

Many single-family dwellings in apartment housings have white that extend through the building from the basement to the chimney fixture on the roof

A

HVAC

40
Q

If walls need to be opened, start at

A

Waste tight to check the space this allows the nozzle to be aimed up the channel towards the top plate or down

41
Q

What frame construction is notorious not for having vertical fire stops?

A

Balloon frame P.405

42
Q

The quickest and most effective way to check for vertical fires spread and a balloon frame building is to

A

Open the siding panels on the outside of the fire area this will expose all the vertical stud channels for extinguishment without smoke, obscuring the view

43
Q

Commercial structures, stores and shopping centers these vertical vent channels are normally placed

A

Towards the rear of the building

44
Q

An apartment buildings, the vertical shaft follow the patterns of the apartment layouts. They are most often found near.

A

Kitchens and bathrooms each chat is usually placed so that it serves two ormore bathrooms

45
Q

O the grave variety and desire of single-family dwellings means that vertical shafts could be located almost anywhere in the structure, however, the location of ‘’’ our good indicators where the can be found

A

Vent pipes and kitchens vents on the roof P. 405

46
Q

A wall that is hot to touch is probably

A

Concealed Fire P. 405

47
Q

If it is known or suspected that a fire has entered, a vertical shaft hose line should be directed’’’’’’’, fires in these channels is confined to a comparably small area thus what hose lines are most useful for this operation?

A

Into the shaft and should be opened and inspected from the roof
1 inch 3/4 LINES P. 406

48
Q

Event hold that assesses the attic space must be

A

Cut to vertically ventilate

49
Q

What nozzle resembles fog applicator and they work the same as by throwing a 360 sphere of water

A

Round nozzles( if used needs to be done before any vertical ventilation occurs) 407

50
Q

If an attic on fire is sprinkler, affected heads would fuse when the temperature reaches

A

165°
8 to 24 gallons per

51
Q

Fire may travel’’’’ through the spaces between ceilings and floors over false or hanging ceilings along ductwork and utility conDUITS through conveyor, tunnels, and industrial buildings and warehouses and through similar channels

A

Horizontally

52
Q

Officers must always carry a

A

TIC / 6 foot Pike pole- reach to Pop CEIlings for exposures P. 408

53
Q

Collapses may occur in as little as 10 minutes with what type of roofs

A

Steel bar JoIST roof

54
Q

An unprotected steel tie, rod and connector that holds the trusses together and the unprotected steel grinders that support them lose their strength and can feel when the steel is subjected to temperatures over

A

1000° for 10 more minutes P. 410

55
Q

In addition to limited access and limited egress, firefighters must also content with regarding basement fires

A

Narrow stairs
No/ limited windows
Small/narrow windows
Nature of stock, product, and other items stored in the basement
Low ceilings
Trapped heat and smoke

56
Q

unfinished basements allow the fire to ‘'’because the floor Joyce, which are often constructed of lightweight, fabricated, wooden i- beams and lightweight steel hangers and gaskets the floor assembly.. if they are exposed they can collapse in as a little a ‘’’’

A

Attacked the floor above
2 to 5 minutes after direct flame contact. p. 411

57
Q

If the incident commander inspected a basement fire and balloon frame construction, the other objective, in addition to keeping ahead of the fire is to

A

Keep the fire from extending to upper floors, including the attic and cock loft area.. no PVV fan should be used in balloon frame construction during the fire attack. 412

58
Q

Basement fires in commercial stores become more difficult solid streams from’’ are needed

A

2/2 inch hand lines

59
Q

If there is a rear door, but no other openings to the basement, the attack can begin from ‘’'’the ventilation effort should be conducted through’’’

A

Conducted through openings at or near areas already burning p. 414

60
Q

If the basement has no outside openings, but only an interior stairway or a trap door entrance to display window openings can be used for ‘’ and the fire can be attacked with’’’

A

Ventilation
Hose design through interior openings or with Bresnan or celler nozzles from the floor above p. 416
