0

This is the stage a fire at which all surfaces and objects within a space has been heated to their ignition temperature and simultaneously ignite all surfaces and objects in the space.

Flashover

1

When does flashover occur?

Between the growth and fully develop stages

2

When do backdraft conditions typically exist?

In the decay stage after the fire compartment has consumed all available oxygen

3

This is observed when flames present and layers of smoke as a result of heated gases that are pushed under pressure from the fire area into uninvolved areas?

Rollover

4

This is the layering of smoke and gas clouds?

Stratification

5

What are the four stages of fire growth?

Incipient
Growth
Fully developed
Decay

6

Rollover should serve as a warning that the fire area may be reaching what point?

Flashover

7

During this stage, fire develops and rollover is often seen in the adjacent compartment?

Growth stage

8

Effective engine company operations rely on the company's ability to do what?

To advance to and extinguish the seat of the fire and all other areas of fire extension inside and outside the structure

9

When should ventilation needs be identified?

When the fire officer complete their size up

10

What does proper ventilation decrease The likelihood of?

Flashover or rapidfire development event any creases the life safety factor of all occupants and firefighters within the fire structure

11

In most situations what should be in place prior to ventilation?

A charged hoseline

12

When using hydraulic ventilation the host rain should cover what percentage of the opening?

80%

13

Using this type of ventilation technique the conditions within the compartment improves and increases visibility to enable the engine company to improve their environment?

Hydraulic ventilation

14

What are the fire ground principles of smoke?

Smoke is potential fuel

Smoke density and color together or an indicator of the flammability

Velocity and pressure or indicators of heat and flowpath

Volume is a indicator of fire intensity

All of the above indicators for a incident profile regarding the location, status, and extent of fire

15

Smoke color is an indicator of what two things?

What is burning

Flammability of the smoke

16

What two things does velocity of smoke indicate

General location of the heat source

The fires current flow path

17

What is the best way for firefighters to maintain their personal safety?

Recognizing a change in the smoke conditions by identifying, reacting, and preventing flashover or rapidfire progression

18

This is the general plan or course of action decided upon to reach the objectives?

The strategy

19

These are the specific actions employed to fill the strategy?

Tactics

20

What is the primary focus of any incident?

Rescue of life
