33

Most dwellings usually have one interior means of access to the cellar.

 

If conditions permit, the status and CELLAR door construction should be determined and communicated to the ___________ ____________

Incident Commander

34

The IC (Chief or Company Officer) should consider ordering an exterior hoseline operated into a cellar window to allow for a quick knockdown when there will be a delay in applying water from the interior or whenever fire conditions dictate.  Some examples are:

  1. Unable to quickly access or locate a secondary cellar entrance and unable to advance down the interior cellar stair.  
  2. Unable to locate any cellar entrance.
  3. At a serious or advanced cellar fire. 
  4. At a cellar fire involving lightweight construction

This should only be attempted when no members are operating in the cellar.  It must be carefully coordinated with and communicated to all units operating on scene

35

The primary consideration for members operating on the first floor above a cellar fire is to _____________________________________________

close the interior cellar door at the top of the stairs

36

The following options should be considered for the safety of the members remaining on the first floor, based on conditions encountered:

  1. Operate under the protection of a charged hoseline on the floor(s) above.
  2. Secure an area of refuge, ensuring a ready means of egress.
  3. Exit the building

37

Note: In an emergency such as members trapped by fire in the cellar or endangered by fire because a collapse has occurred, the IC should order:

 the immediate operation of a hoseline into a cellar window. 

 

It is a good practice at PD fires, especially serious cellar fires, to have a precautionary charged hoseline in position near the front of the building for these contingencies

38

Various factors, including the following, would preclude the descent of
the first hoseline down the interior cellar stairs:

 

HISS

HISS

  1. High heat conditions at the top of the stairs
  2. Questionable stability of the stairway
  3. Immediate availability of a second hoseline
  4. Initial size-up indicating a serious fire condition

39

The ___________________ is the paramount concern in making the decision to advance down the interior cellar stairs

The safety of members is the paramount concern in making the decision to advance down the interior cellar stairs

40

In situations where the first line is advanced through the main entrance and the first hoseline does not advance into the cellar, then the first hoseline will maintain its position on the first floor (if safety allows) to:

  1. Protect the interior stairs leading to the floors above
  2. Protect members conducting searches on the first floor and the floors above
  3. Extinguish any fire that is extending from the cellar

41

The first hoseline will remain on the first floor (if safety allows) until:

the cellar fire is controlled

42

The decision to reposition the first hoseline to a secondary entrance can only be made by

an Acting Chief Officer/Chief Officer

43

What factors should be considered before repositioning the hoseline from the interior stairs to an alternative entrance?

 

 

The Incident Commander should transmit an_______ message utilizing the emergency alert button to broadcast this to all members and ensure an _______________ from all units/members operating in the interior.

  1. Is another hoseline available on scene.
  2. Is repositioning of the hose line necessary to save or protect life.
  3. Will any further delay in the application of water severely expose an adjoining property

The Incident Commander should transmit an URGENT message utilizing the emergency alert button to broadcast this to all members and ensure an acknowledgement from all units/members operating in the interior.

44

Ladder company members operating on the first floor must be withdrawn before the first hoseline is repositioned from that floor.  

The forcible entry team will then operate with the engine company and facilitate the advance of the hoseline via a secondary entrance

Members operating on the upper floors may also need to be withdrawn to a safe area if no portable ladders are positioned and readily available. This is done for reasons of safety and operational efficiency.

45

The IC should consider the following tasks for placement of the second hoseline:

  • Backing up the first hoseline.
  • Used for exposure protection.
  • Stretched into an exposure.
  • Used to extinguish auto-exposure on the structure.
  • Stretched to the first floor through the main entrance door to extinguish fire and/or protect members operating on the upper floors.
  • Enter the cellar via a secondary entrance if present
  • Apply water into a cellar window (or Bilco door) for a quick knockdown if there is a heavy fire condition or entry is delayed

46

Prior to committing the first hoseline to a first floor fire, what must members determine?

During the initial size-up at apparent first floor fires, members should ensure they check to determine that the fire did not start in the cellar, before committing the first hoseline

47

Whenever the first arriving engine company backstretches to the hydrant, they should consider dropping ___hoselines in front of the building.

Whenever the first arriving engine company backstretches to the hydrant, they should consider dropping two hoselines in front of the building.

48

49

BUILDING FULLY INVOLVED

Operate the hoseline on the exterior to protect exposures before:

entering the building.

50

BUILDING FULLY INVOLVED

Buildings fully involved have an increased collapse potential and require a complete evaluation by

the IC before entering

51

Consider stretching a 2½ inch hoseline for

  • a faster knock down
  • greater reach of stream
  • increased volume of water 
  • increased exposure protection.

Note: A 2½ inch hoseline shall also be considered when encountering a wind impacted fire. or a heavily involved first floor fire in a larger style Private Dwelling (Queen Anne

52

Queen Anne

Roof ventilation is not an initial concern, but when it is, Who conducts roof ventilation on a Queen Anne

It is generally performed by a Later Arriving Unit

76

Can the first Ladder Co. Officer make a decision to advance down the interior cellar stairs without a hoseline?

 

If so, what action must be taken?

Yes, when no hoseline is immediately available and if fire conditions permit.

 

One member should remain at the top of the cellar stairs to control the door.  Door control at the top of the cellar stairs is essential when searching without the protection of a hoseline to ensure ladder company members do not create a flowpath which can dramatically change conditions in the cellar

77

When entering the cellar via a secondary entrance, there is often an interior door that leads to the first floor at the top of the stairs.  If this door is found open, it should be closed to reduce the amount of oxygen feeding the fire and prevent a potential flowpath for the fire.  The officer should communicate the status of this door to?

 the second ladder officer and the IC

78

Bilco style doors may cover an exterior cellar entrance.  This type of secondary entrance often requires extensive forcible entry, and is more indicative of an unoccupied cellar. 

Is this a good option for line advancement?

Utilizing this type of entrance for line placement is the least desirable of the secondary entrances and shall not be utilized for hoseline placement unless it is the only option

79

Indications of an open interior cellar door when entering through the entrance door are:

  • A thermal imaging camera showing heat waves emanating across the first floor ceiling when entering the first floor via the entrance door.
  • Smoke action seen on the first floor seen at the entrance door - such as smoke showing significant force and speed under pressure

80

Due to the limited means of access to most attics, the ladder company must be prepared to assist the engine company in alternate means of getting water on the fire.  This can be achieved by opening up a ________ of the ceiling on the floor below.  The engine company could then operate from a small extension ladder to sweep the attic space with the hoseline

3' section

81

If wood is encountered when making the initial opening, you may have encountered an attic catwalk.  Shifting about ________ to one side and making another opening may avoid this type of obstruction.  The bent tip and/or cockloft nozzle may also be used effectively in this situation
