Ignition Device: Mechanical, chemical, or electrical means used to initiate a fire.

Question 18

PROTECTED AREA:

Answer 18

Protected Area: The clean or unburned area left by stock, furniture, contents, etc. covering shelves, floors, or other combustible areas.

Question 19

Flow Path

Answer 19

FLOW PATH - is the movement of heat and smoke from the higher air pressure within the fire area to all other lower air pressure areas both inside and outside of a fire building

Question 20

Heat Release Rate

Answer 20

HEAT RELEASE RATE - is the rate at which energy (heat) is released by the burning of a fuel and oxygen mixture

Question 21

Ventilation Limited Fire

Answer 21

Ventilation Limited Fire - is a fire in which the heat release rate or growth of the fire is being slowed because the fire is consuming the available oxygen and no new oxygen is entering the fire area.

Question 22

FOWPATH

Answer 22

The term Flow Path describes the movement of fire, heat and smoke from an area of high pressure (the fire area) to an area of low pressure (all areas other than the fire area).

Question 23

CATENARY WIRES

Answer 23

CATENARY WIRES – Overhead electrical wires delivering approximately 12,000 (12KV) volts of alternating current (AC). These lines retain residual static electricity after the power source has been disconnected. The removal of this residual electricity requires the railroad to have a Class “A” employee (A Man) ground the catenary on the tracks/tunnel circuit where power removal was requested by the Incident Commander (IC).

Question 24

Incipient:

Answer 24

Incipient: The early stage of fire development where the fire’s progression is limited to a fuel source and the thermal hazard is localized to the area of the burning object.

Question 25

Growth:

Answer 25

Growth: The stage of fire development when the heat release rate from an incipient fire has increased to the point where heat transfers from the fire and causes the combustion products to pyrolyze adjacent fuel sources. The fire begins to spread across the ceiling of the fire compartment (rollover).

Question 26

Fully Developed:

Answer 26

Fully Developed: The stage of fire development which has reached its peak heat release within a compartment. This usually occurs after flashover, resulting in floor to ceiling burning within the compartment thereby creating heat conditions untenable for members.

Question 27

Decay:

Answer 27

Decay: The stage of fire development within a structure characterized by either a decrease in the fuel load or available oxygen to support combustion, resulting in lower pressure and lower temperatures in the fire area.

Question 28

Fire partition

Answer 28

Fire partition - A partition provided for the purpose of protecting life by furnishing an area of exit, or refuge, and having a fire resistive rating of at least three hours as per the 1938 Building Code.

Question 29

FIREPROOF CONSTRUCTION

Answer 29

Fireproof construction - A building in which the walls, floors, structural members and stairway enclosures are made of non-combustible materials with fire resistive ratings as required by the Building Code.

Question 30

FIRE STOPPING

Answer 30

FIRE STOPING - The closing of all concealed draft openings to form a barrier against the spread of fire with non-combustible materials.

Question 31

FIRE WALL

Answer 31

Fire wall - A fire-rated, smoke tight wall having protected openings designed to restrict the spread of fire from one structure to another, or from one area of a structure to another. It extends continuously from the foundation to, or through, the roof with sufficient structural stability to withstand the collapse of construction on either side of it. Fire Wall ratings for 1968 BC are rated at 4 hours; 2008 BC are rated at 2 or 3 hours depending on occupancy.

Question 32

Question 39

UNDER CONTROL

Answer 39

Under Control: Indicates that at this time, in the judgment of the Incident Commander, final extinguishment of the fire or control of the emergency will be accomplished by the apparatus, equipment and personnel on the scene.

Question 40

HEAVY FIRE SITUATION

Answer 40

Heavy Fire Situation: Indicates a fire that will require the operation of more than two (2) hoselines to extinguish the fire or requires the use of hoselines in conjunction with the use of heavy appliances. When describing a fire as a Heavy Fire Situation, include a quantitative description of the fire: Location, volume, and direction of travel.

Question 41

STANDING FAST

Answer 41

Standing Fast: Indicates that a unit is held in reserve status, intact as a unit at the Incident Command Post or Staging Area and is immediately available to the Incident Commander.

Question 42

Incendiary Fire

Answer 42

Incendiary Fire: A designation given to a fire, in which the Fire Marshal has determined through physical examination of the fire scene and interview with witnesses that the fire was intentionally set by someone. A fire may be suspected of being incendiary if there is evidence of, among other things, the presence of an accelerant or a firesetting device, two or more separate and distinct fires burning at the same time, an eye witness to the setting of the fire, a confession, or a combustible substance deliberately placed at the point of origin.

Question 43

SUSPICIOUS FIRE

Answer 43

Suspicious: A designation given by the Incident Commander in command of a fire operation and is one of the circumstances in which the Fire Marshal is called to the fire scene to investigate and determine the cause, origin and circumstances of the fire. A fire is suspicious if:

• There are indications that the fire may have been set and all accidental causes have not been eliminated. (When all accidental causes have been eliminated, the fire is incendiary.)
• A threat preceded the fire.
• It is one in a series of similar fires.
• Premises normally locked are found unlocked.
• Stock or belongings were removed prior to the fire.
