1

In the 1920s homes were provided with 30 amp electrical service what amp is typical today

200 amp service is typical

2

The useful lifespan of a building can range from

25 to 100 years or more

3

The varying ages of buildings within a community present challenges to firefighters because

Construction technology is continually evolving

4

Building variables that can affect the course of the fire are

Age of building, fire protection systems, occupancy type, fuel load, construction type, configuration, building access and exposure

5

Process of restoring run down or deteriorated Properties bite more affluent people often displacing poor residence

Gentrification

6

The age of the building affect the occurrence and behavior of

Fire, in indirect ways

7

Effects of aging are

Not uniform

8

Older buildings sometimes offer advantages to the firefighter because of design methods in the past. Extra structural mass was used. What is the benefit

Greater mass often results in greater structural stability under fire conditions

9

Lighter more efficient structural materials, although structurally sound, might

Fail more quickly than older heavier members under fire conditions

10

The first line of defense in a building is

Automatic fire protection systems, sprinkler systems

11

The occupancy of the building often affects

Ways in which building components behave under fire conditions, do two different types of fuels and hazards in different types of occupancies

12

Amount of fuel present expressed quantitatively in terms of weight of fuel per unit area. This may be available fuel or total fuel and is usually dry weight

Fuel load

13

Changes in occupancy frequently will result in a significant difference in the

Amount and type of combustible materials, an increase that may tax existing sprinkler systems or structural design for fire safety

14

Who plays an important role in detecting hazards associated with occupancy change

Fire inspectors, usually discovering change during routine inspection

15

Nothing is more fundamental to a building than

The materials from which it is constructed

16

The traditional construction classifications

Fire resistive.
Noncombustible.
Masonry or ordinary.
Heavy timber.
Woodframe.

17

The contemporary building code numerical designation for various construction type

Type I. Fire resistive
Type II. Protected noncombustible or noncombustible
Type III exterior protected
Type IV heavy timber
Type V woodframe

18

In a scientific sense the laws of physics and chemistry that govern fire behavior

Never change

19

Each building type classification is further divided into

Sub classifications

20

This refers to a buildings general shape or layout

Configuration

21

Building designers tend to be more concerned with

The functionality of the structure and it's a visual appeal

22

The primary factor for firefighter operations in building construction

Access

23

Features that cause access problems such as steep slopes rivers and landscaping

Terrain features

24

Things that cause access problems like narrow roadways, setbacks, and barriers for security

Built out environments

25

Structure or separate part of the fire ground to which the fire could spread

Exposure

26

Large uncontrollable fire covering a considerable area crossing natural fire barrier is usually involves buildings more than one block and causes a large fire loss forest fires also consider this

Conflagration

27

The earliest provisions of building codes were directed at the danger of

Conflagration's

28

Some of the earliest fire regulations adopted in colonial Boston prohibited

Thatched roofs to prevent the spread of fire

29

NFPA defines a building as an exposure when

The heat from an external fire my cause ignition or damage to the exposed building

30

In tactical firefighting the term exposure is also used to refer to

A structure or object such as a propane take her pile of lumber to which fire could spread
