Q

2 Concerns raised with UFADS pose life safety risks

A

1- If Smoke develops under a floor it will be distributed into the space floor level

2- Water may enter the underfloor area and result in a short circuit that could cause a fire in the UFADs electrical system

Q

when the officer is in charge of an incident that will involve automatic aid he is responsible for the following (3)

A

Requesting the dispatcher to instruct all responding units to acknowledge that they are on the assigned radio frequency

Assigning units based on arrival time and capabilities

Establishing and communicating the location of staging areas

17
Q

Mutual Aid is

A

A reciprocal agreement between two or more fire and emergency services organizations.

18
Q

Additional Aid is

A

Similar to mutual aid except that payment rather then reciprocal aid is made by one agency to the other

19
Q

Company officers should survey building that are

A

While under construction

20
Q

Purlin is

A

Horizontal member between trusses that support the roof

21
Q

Every structure is composed of the basic building elements (5)

A

Structural Frame

Load bearing walls both interior and exterior

Non load bearing walls and partitions both interior and exterior

Floor Construction

Roof Construction

22
Q

Type 1 Construction

A

All structural members are composed of only noncombustible materials that posses a high fire resistance rating

23
Q

Type 2 Construction

A

Composed of materials that will not contribute to fire development or spread

24
Q

Type 3 Construction

A

Requires that exterior walls be constructed of non combustible materials, typically masonry, most common in churches schools apartment buildings and mercantile structures

25
Q

Type 4 Construction

A

Is often referred to as heavy timber construction

26
Q

Type 5 Construction

A

Is often referred to as wood frame or frame construction

27
Q

Factors that affect Strategy and tactics in fire within Type 1 (6)

A

High occupancy load and occupancy type

Location of fire and number of floors involved

Access/egress

Ventilation difficulties

Building safety Features

Resource needs

28
Q

Factors that affect Strategy and tactic in fire within type 2 (6)

A

Confirming the actual type 2 construction

Mixed occupancy types within the structure

Likely areas of collapse due to construction features

Potential large area and volume for fire growth

contents and processes

Hoseline Deployment and search tactics

29
Q

Factors that affect Strategy and tactic in fire within type 3 (4)

A

Voids exist inside the wooden channels that roof and truss systems create that will allow fire spread unless proper fire stopping is applied

Renovation in older type 3 structures may have resulted in greater fire risk due to the creation of large void above ceilings and below floors

New construction material my have been substituted for original materials during renovations. this substitution may result in reducing the load carrying capacity of the supporting structural member

the original use of the structure may have changed to one that requires a greater load carrying capacity that that of the original design

30
Q

Factors that affect Strategy and tactic in fire within type 4 (5)

A

Occupancy type and use

Specific requirements for apparatus placement due to potential collapse of structure

Lack of sufficient fire protection systmes

Conditions that require high fire flow/supply water

Potential limited access

31
Q

Factors that affect Strategy and tactic in fire within type 5 (5)

A

High life Hazard

Structure contributes to the fire with early collapse potential

Rapid Fire spread due to the construction and age of the building

non permitted remodeling and alterations to the building

open floor plans and void spaced do no limit the ability’s of fire and smoke to travel through the structure

32
Q

Five Categories of Factory built homes

A

Manufactured

Modular

Panelized

Precut

Hybrid Modular

33
Q

Cockloft is

A

A space 2 to 3 feet in height that is found over commercial building spaces and is not designed for human habitation

34
Q

Plenum is

A

Open space or air duct above a drop ceiling that is part of the air distribution system

35
Q

8 Factors that should be considered when trying to determine the potential for structural collapse include

A

Construction type

Age structure

Renovations additions and alterations

Contents

Length of time the fire has been burning

Stage of the fire

Amount of water used to extinguish the fire

Weather

36
Q

Collapse zone

A

Height of the structure multiplying it by a factor of 1-1/2

37
Q

Collapse Zone should be established when (3)

A

There is an indication that prolonged exposure to the fire or heat has weakened the structure

A defensive strategy has been adopted

Interior operations cannot be justified

38
Q

250 GPM adds ______ per minute to the structure

A

1 Ton of water
