Q

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:

A
  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
Q

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

A

close the interior cellar door at the top of the stairs

36
Q

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

A
  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
Q

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:

A

** 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
Q

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

HISS

A

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
Q

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

A

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

40
Q

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:

A
  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
Q

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

A

the cellar fire is controlled

42
Q

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

A

an Acting Chief Officer/Chief Officer

43
Q

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.

A
  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
Q

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

A

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
Q

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

A
  • 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
Q

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

A

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
Q

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