high occupancy and load
location of fire and number of floors
access/egress
building safety
ventilation difficulties
resources needed

Question 19

type 2 factors that affect strategy

Answer 19

confirming the actual type
mixed occupancy
likely areas of collapse due to construction features
potential large area and volume for growth
contents and processes
hoseline deployment and search tactics

Question 20

type III factors that affect strategy

Answer 20

voids exist inside the wooden channels that roof truss systems create unless proper fire stopping is applied
renovations in older type 3 structures may result in greater fire risk due to larger voids created
new construction materials may have been substituted for original materials during reno.
use of structure may have changed

Question 21

type IV factors that affect strategy

Answer 21

occupancy type
specific apparatus placement due to potential collapse
lack of sufficient fire pro systems
conditions that require high fire flow/supply water
potential limited access

Question 22

type V materials

Answer 22

wooden boards
plywood
oriented strand board OSB

Question 23

type V factors affecting strategy

Answer 23

high life hazard
structure contributes to the fire with early collapse potential
rapid fire spread due to construction and age of building
non permitted remodeling and alterations
open floor plans and void spaces do not limit the ability of fire and smoke to travel

Question 24

steps in decision making process (5)

Answer 24

ID and prioritize the problems
define best solution
implement solution
monitor results
adjust plan as necessary

Question 25

Command staff organizational levels

Answer 25

Branch Division Group Unit

Question 26

Branch

Answer 26

organizational level having functional/ geographic responsibility for major segments of incident operations. located between section and division or group. defined by roman numeral IE command or ops.

Question 27

division

Answer 27

having responsibility for ops within a defined geographic area. between branch and single resources, task force, or strike team. resources assigned to that division report to that division super.

Question 28

group

Answer 28

organizational level, equal to division having responsibility for a specific functional assignment at an incident. without regard to a specific area. when assigned function is completed they will be reassigned.

Question 29

unit

Answer 29

level within the section the fulfill specific support functions such as the resources, documentation, demob, and situational units within the planning section.

Question 30

Quantity and movement of smoke indicate

Answer 30

potential fuels and potential hazards location and stage of fire and travel direction

Question 31

smoke color

Answer 31

differ between fuels, such as legacy and modern, tar,soot, and carbon are most common heated particles found in smoke giving it the black color. water vapor and heated gases give the white color

Question 32

light colored smoke/ slow moving

Answer 32

can indicate if smoke has traveled distances from origin. a small amount fo smoke from a large structure could easily indicate a well seated fire inside

Question 33

white smoke

Answer 33

light white smoke indicates pyrolysis is occurring in areas adjacent to the main body of fire. It indicates moisture and gases are being released from the product.

Question 34

brown smoke

Answer 34

common in mid stage heating as moisture mixes with gas and carbons. indication of burning wood, whether unfinished found largely in attics pr finished found in structural wood members.

Question 35

grey smoke

Answer 35

combination of mixing. It can be mid stage heating with white,brown, or black, or it can be when different smoke areas combine. can indicate smoke changes from mid stage to high heat.

Question 36

black smoke

Answer 36

high quantities of carbon particles and is also and indicator of the amount of ventilation available at the seat of the fire. The thicker the smoke, the less clean burning and less oxygen available, as smoldering fires produce massive amounts of black smoke.

Question 37

thick black smoke

Answer 37

suggests fire is in late stage of pyrolysis which produces large amounts of carbon as unburned product

Question 38

black fire

Answer 38

refers to dense black smoke that is ready to ignite possibly at the vent point

Question 39

3 common types of smoke movement

Answer 39

floating/hanging volume pushed heat pushed heat will determine smoke speed

Question 40

occupant survival profile type of size up that should be used when evaluating victim survivability what questions are asked?

Answer 40

are occupants suspected of or known to be trapped? is it reasonable to assume that the occupants are still alive?

Question 41

residential occupancy type

Answer 41

hotels,motels, and guest accommodations are likely to be occupied by transient residents not familiar with the structure, the exits, or evac plans

Question 42

incident priorities

Answer 42

life safety incident stabilization property conservation

Question 43

investigation option (nothing showing)

Answer 43

when the problem is not obvious the IC should establish command and announce nothing showing

Question 44

fast attack or mobile command option

Answer 44

first arriving unit has the responsibility of assuming command of the incident. at most incidents the company officer will be initial IC. Mobile command is an option to him.

Question 45

situations when mobile command can be used

Answer 45

life safety; victim rescue offensive fire attack any incident when FF safety is a major concern when further investigation is required by company officer crew members need closer supervision from being new or inexperienced

Question 46

stationary command option

Answer 46

because of nature or potential for rapid expansion of some incidents, immediate and strong overall command is needed.

Question 47

stationary command set up

Answer 47

name the incident designated location of the incident command post give initial report on conditions request additional resources initiating the use of tactical worksheet

Question 48

VEIS vent enter isolate search

Answer 48

vent enter isolate search

Question 49

direct attack

Answer 49

solid or straight stream of water or foam most efficiently on fuel controlled fires the primary fuels burning in these fires are the combustibles located within the compartment

Question 50

direct attack considerations

Answer 50

arrival conditions location,size,extent of fire available resources size of the structure structural features that may affect interior suppression ease of access to the burning fuel hose stream type and application potential flow paths within the structure

Question 51

indirect attack

Answer 51

use of a solid or straight stream uses water most efficiently on vent controlled fires. primary fuel within these types of fires are the fire gases that the combustion process inside of a compartment produce. can be considered gas cooling if performed on the interior of structure. Additionally could be considered transitional if started exterior.
